The Security Service of Ukraine (Ukrainian: Служба безпеки України, romanized: Sluzhba bezpeky Ukrainy [ˈsluʒbɐ bezˈpɛkɪ ʊkrɐˈjinɪ]; abbreviated as SBU [СБУ] or SSU) is the main internal security agency of the Ukrainian government. Its main duties include counter-intelligence activity and combating organized crime and terrorism. The Constitution of Ukraine defines the SBU as a military formation, and its staff are considered military personnel with ranks. It is subordinated directly under the authority of the president of Ukraine.[5] The SBU also operates its own special forces unit, the Alpha Group.

The SBU was created after the Declaration of Independence of Ukraine in 1991. The agency was viewed negatively by the Ukrainian public for much of its history, as it was widely regarded as corrupt and was best known for arresting and intimidating political dissidents. After the Revolution of Dignity in 2014, the SBU went through a restructuring with the transition to the new government, because of its corruption and possible infiltration by intelligence agencies of Russia.[6]

The SBU carries out operations that in many other countries are the responsibility of the police and special forces rather than counter-intelligence services.

The SBU has since been involved in operations against Russia, pro-Russian separatists in Donbas and other Russian sympathizers after the start of the war in Donbas and the wider Russo-Ukrainian War.[7]

Duties and responsibilities

[edit]

The Security Service of Ukraine is vested, within its competence defined by law, with the protection of national sovereignty, constitutional order, territorial integrity, economical, scientific, technical, and defense potential of Ukraine, legal interests of the state, and civil rights, from intelligence and subversion activities of foreign special services and from unlawful interference attempted by certain organizations, groups and individuals, as well with ensuring the protection of state secrets.[8]

Other duties include combating crimes that endanger the peace and security of mankind, terrorism, corruption, and organized criminal activities in the sphere of management and economy, as well as other unlawful acts immediately threatening Ukraine's vital interests.

The SBU carries out operations that in many other countries are the responsibility of the police and special forces rather than counter-intelligence services.[9]

Organization

[edit]

The general structure and operational methods of SBU appear to be very similar to that of its predecessor (KGB of Ukrainian Soviet Socialist Republic) with exception of Ukrainian Border Guards and department responsible for security of high-rank state officials. Both of them became independent institutions. However, the SBU keeps under its control special operation Alpha units with bases in every Ukrainian province. According to British political expert Taras Kuzio the organizational structure of SBU remains bloated in size compared to its predecessor, the Soviet Ukrainian KGB, with the total number of active officers being as high as 30,000 personnel. It is six times larger than the British domestic MI5 and external MI6 combined.[10]

History

[edit]

Ukrainian security services in Soviet era

[edit]

On January 14, 1918, the Ukrainian People's Republic founded its Security Services.[11]

In May 1918 the Department of the State Guard of the Ministry of Internal Affairs of the Ukrainian State started to form a new intelligence service.[11] This was a much more effective agency than its predecessor due to the incorporation of former employees of Okhrana (the secret police force of the Russian Empire).[11] After the fall of the Ukrainian State and the return of power of the Ukrainian People's Republic (UNR) in December 1918, the new UNR authorities destroyed virtually all of the state infrastructure of the Ukrainian State.[11] Therefore, the new secret services founded in January 1919 (with two divisions – domestic and foreign) had to start practically from scratch.[11][12] It never became as well-led, nor as successful, as its forerunner, the security services of the Ukrainian State.[11][12] The security services of the West Ukrainian People's Republic on the other hand were well-organized.[11] The West Ukrainian People's Republic were formed in March 1919 as the Field Gendarmerie of the Ukrainian Galician Army (it also served as military police).[11] There was no cooperation between the security services of the West Ukrainian People's Republic and Ukrainian People's Republic.[11]

In 1924, former (April–July 1919) head of intelligence of the Ukrainian People's Republic Mykola Chebotarov started intelligence work on his own initiative for the Ukrainian People's Republic government in exile on the territory of the Ukrainian SSR.[13]

SBU Alpha Group operators

The All-Ukrainian Cheka was formed on December 3, 1918, in Kursk[14] on the initiative from Yakov Sverdlov and Lenin's orders. The commission was formed on the decree of the Provisional Workers' and Peasants' Government of Ukraine and later adopted on May 30, 1919, by the All-Ukrainian Central Executive Committee. To support the Soviet government in Ukraine, in Moscow was formed a corps of special assignment with 24,500 soldiers as part of the All-Ukrainian Cheka. In spring 1919, there was created the Council in fight against counterrevolution and consisted of Adolph Joffe, Stanislav Kosior, and Martin Latsis. In its early years the security agency fought against the "kulak-nationalistic banditry"[15] (peasants who resisted having their land confiscated and being forced into collective farms). On August 19, 1920, the All-Ukrainian Cheka arrested all members of the All-Ukrainian Conference of Mensheviks after accusing them of counterrevolutionary activity.[16] On December 10, 1934, the State Political Directorate of Ukraine was dissolved, becoming part of the NKVD of Ukraine.[14]

1990s–2005

[edit]
SBU Headquarters in Kyiv

The SBU originated from the Ukrainian Soviet Socialist Republic's Branch of the Soviet KGB, keeping the majority of its 1990s personnel.[17] It was created in September 1991 following the August 1991 independence of Ukraine.[11] The last Ukrainian Soviet Socialist Republic's Branch head Colonel-General Nikolai Golushko stayed on as chairman of the newly formed Security Service of Ukraine for four months before moving to Russia.[11] (Golushko headed the Russian Federal Counterintelligence Service in 1993 and 1994.[11])

Since 1992, the agency has been competing in intelligence functions with the intelligence branch of the Ukrainian Ministry of Defense. Despite this, a former Military Intelligence Chief and career GRU technological espionage expert, Ihor Smeshko, served as an SBU chief until 2005.

According to Taras Kuzio during the 1990s in some regions of Ukraine (Donetsk) the SBU teamed up with local criminals taking part in privatization of state property (so-called prykhvatizatsiya) ignoring its operational objectives and sky-rocketing level of local violence. A notorious incident took place in December 1995 in Western Ukraine when a local citizen Yuriy Mozola was arrested by SBU agents, interrogated and brutally tortured for three days. He refused to confess in trumped up murder charges and died in SBU custody. Later it turned out that the real killer was Anatoly Onoprienko. He was arrested the next year.[10]

Reports of SBU involvement in arms sales abroad began appearing regularly in the early 2000s.[17] Ukrainian authorities have acknowledged these sales and arrested some alleged participants.[17]

In 2004, the SBU's Intelligence Department was reorganized into an independent agency called Foreign Intelligence Service of Ukraine. It is responsible for all kinds of intelligence as well as for external security. As of 2004, the exact functions of the new service, and respective responsibilities of the Foreign Intelligence Service of Ukraine were not regulated yet. On November 7, 2005, the President of Ukraine created the Ukraine State Service of special communications and protection of information, also known as Derzhspetszvyazok (StateSpecCom) in place of one of the departments of SBU and making it an autonomous agency. The SBU subsumed the Directorate of State Protection of Ukraine (Ukrainian: Управління державної охорони України), the personal protection agency for the most senior government officials, which was the former Ninth Directorate of the Ukrainian KGB.

The SBU's State Directorate of Personal Protection is known for its former Major Mykola Mel'nychenko, the communications protection agent in President Leonid Kuchma's bodyguard team. Mel'nychenko was the central figure of the Cassette Scandal (2000)—one of the main events in Ukraine's post-independence history. SBU became involved in the case when Mel'nychenko accused Leonid Derkach, SBU Chief at the time, of several crimes, e.g., of clandestine relations with Russian mafia leader Semyon Mogilevich. However, the UDO was subsumed into the SBU after the scandal, so Mel'nychenko himself has never been an SBU agent.

Later, the SBU played a significant role in the investigation of the Georgiy Gongadze murder case,[18] the crime that caused the Cassette Scandal itself.

In 2004, General Valeriy Kravchenko, SBU's intelligence representative in Germany, publicly accused his agency of political involvement, including overseas spying on Ukrainian opposition politicians and German TV journalists. He was fired without returning home. After a half-year of hiding in Germany, Kravchenko returned to Ukraine and surrendered in October 2004 (an investigation is underway).

Later, the agency commanders became involved in the scandal around the poisoning of Viktor Yushchenko—a main candidate in the 2004 Ukrainian presidential election. Yushchenko felt unwell soon after supper with SBU Chief Ihor Smeshko, at the home of Smeshko's first deputy. However, neither the politician himself nor the investigators have ever directly accused these officers. The Personal Protection department has been officially responsible for Yushchenko's personal security since he became a candidate. During the Orange Revolution, several SBU veterans and cadets publicly supported him as president-elect, while the agency as a whole remained neutral.

2005–2010

[edit]

In 2005, soon after the elections, sacked SBU Chief Smeshko and other intelligence agents stated their own version of the revolution's events. They claimed to have prevented militsiya from violently suppressing the protests, contradicting the orders of President Kuchma and threatening militsiya with armed involvement of SBU's special forces units. This story was first described by the American journalist C.J. Chivers of The New York Times and has never been supported with documents or legally.[citation needed]

An episode of human rights abuse by SBU happened during the case of serial killer Anatoly Onoprienko. Yuriy Mozola, an initial suspect in the investigation, died in SBU custody in Lviv as a result of torture. Several agents were convicted in the case.[19] The SBU remains a political controversial subject in Ukrainian politics.[20]

2010–2014

[edit]

The former Security Service of Ukraine Head Valeriy Khoroshkovsky was involved in several controversies during his tenure. The rector of the Ukrainian Catholic University in Lviv Borys Gudziak heavily criticized a visit from the SBU, forcing Khoroshkovskiy to apologize. Later the head of the Kyiv Bureau of the Konrad Adenauer Foundation, Nico Lange, was detained for a short while and released only after several high-ranking officials from the German Chancellery vouched for him. The Security Service described the incident as a misunderstanding.[21] Khoroshkovskiy, as the Chairman of the SBU, eliminated the main competition of Ukrainian TV-giant Inter,[citation needed] officially owned by his wife Olena Khoroshkovskiy, in the face of TVi and Channel 5. In July 2010, Konrad Schuller of the Frankfurter Allgemeine Zeitung wrote that Khoroshkovskiy had connections with RosUkrEnergo.[22][23][24] The most important source of Khoroshkovskiy's[clarification needed] came from RosUkrEnergo.[citation needed] The President's spokesperson, Hanna Herman, in an interview with this newspaper, did not dispute that Dmytro Firtash was one of the sponsors of the Presidential Party of Regions, with the help of which Khoroshkovskiy was appointed to the position of the State Security chairman. Khoroshkovskiy denied any connections to RosUkrEnergo. However it is a fact[citation needed] that Firtash possesses certain privileges in Inter. Schuller also stated that the SBU acts in direct association with RosUkrEnergo, arresting their main opponents (see RosUkrEnergo) to recover their invested money in the recent[which?] presidential campaign. Khoroshkovskiy having declined to give an interview to Frankfurter Allgemeine Zeitung, Schuller posted a quote from one of his other interviews:

All my experience until now indicates that I am a patriot. ... I see through economic intrigues, crime, know methods of money laundering, banks that illegally exchange currency. ... My knowledge is much wider than most of those who work here.

When Minister of Finance Fedir Yaroshenko resigned on January 18, 2012, Khoroshkovsky replaced him in the post on the same day.[25] Khoroshkovsky is also the owner of U.A. Inter Media Group which owns major shares in various Ukrainian TV channels including Inter TV.[26] 238 members of the Verkhovna Rada voted for Khoroshkovsky, however the head of the parliamentary committee for the National Security and Defense Anatoliy Hrytsenko stated that the committee accepted the decision to recommend Verkhovna Rada to deny the candidature of Khoroshkovskiy on the post of the chairman of Security Service of Ukraine.[27]

Khoroshkovskiy said the SBU's main duty was to protect the president rather than the interests of Ukraine. On July 26, 2010, it arrested an internet blogger, producing a warrant for his arrest the next day. SBU accused the blogger of threatening the President of Ukraine, citing his comment "May thunder strike Yanukovych!"; he was released after a short discussion.[28] However, SBU showed a rather passive reaction to the statements of the Russian state official who claimed that Crimea and Sevastopol belong to the Russian Federation.[29] Protest group FEMEN said that after the early 2010 election of President Viktor Yanukovych the SBU attempted to intimidate the FEMEN activists.[30]

A SBU raid against organized crime in Sumy Oblast

On May 22, 2012, Volodymyr Rokytskyi, Deputy Head of the SBU, was photographed in public wearing a $32,000 luxury wristwatch despite the fact that its price amounts to his yearly official income. The instance happened at a joint Ukrainian-American event dedicated to fighting the drug trade.[31]

The SBU uncovered seven spies and 16 special service agents in 2009.[32] A large number of arrests and searches occurred in 2011.[33]

2014–2022

[edit]

In February 2014, numerous documents, hard drives, and flash drives, including data on over 22,000 officers and informants, were stolen or destroyed in a raid on the SBU allegedly ordered by President Viktor Yanukovych.[34]

Late February 2014 opposition MP Hennadiy Moskal released papers that showed the SBU had allegedly infiltrated the late 2013 – February 2014 anti-government Euromaidan protest.[35] According to BBC Ukraine analyst Olexiy Solohubenko, many tactics discussed in the paper had indeed been performed.[35]

After the overthrow of Yanukovich in the Revolution of Dignity the new SBU head Valentyn Nalyvaichenko claimed to have found his new office building empty, saying "the agency's former leadership had all fled to Russia or Crimea. There were no operative files, no weapons. Institutionally, the place was totally destroyed".[6] Nalyvaichenko also claimed that at that time the agency was heavily infiltrated by Russian spies.[6] Indeed, Nalyvaichenko predecessor Oleksandr Yakymenko with about 15 former SBU top officials surfaced in Russia a few days later.[34] Allegedly in the months following the Revolution of Dignity thousands of Ukrainian spies switched sides and began reporting to Russia during the 2014 Crimean crisis and the pro-Russian unrest in east and south Ukraine.[34] At the end of 2014 235 SBU agents, including the former counterintelligence chief and his cousin, and hundreds of other operatives had been arrested and 25 high treason probes against Yanukovych-era SBU officials had been launched; also all regional directors had been changed, as well as half of their deputies.[34] In July 2015 Nalyvaichenko claimed "There's no longer a total infiltration of Russian agents. The danger is no longer widespread".[6] The arrested agents were replaced by new recruits from western Ukraine, many of them in their early twenties.[34] To test loyalty, all SBU agents are subjected to recurrent interrogations and lie detector tests.[34]

In June 2015, the Kyiv Post reported that a deputy chief of the SBU, Vitaly Malikov, had supported events leading to the annexation of Crimea.[36] According to February 2016 official figures of the Ukrainian parliamentary Committee on National Security, after Russia's annexation 10% of SBU personnel left Crimea.[37] According to the SBU itself (in November 2017) 13% did so.[38]

In 2016, Amnesty International and Human Rights Watch reported that the SBU operates secret detention facilities where civilians are held incommunicado being subjected to improper treatment and torture.[39]

In 2017, the United Nations Human Rights Monitoring Mission in Ukraine (HRMMU) expressed concerns about a situation with "freedom of opinion and expression" in Ukraine which facing "mounting challenges". According to the UN reports the SBU is taking advantage of broad interpretation and application of Ukrainian Criminal Code against independent Ukrainian journalists, bloggers, and media activists.[40] According to reports of the United Nations Human Rights Monitoring Mission in Ukraine, the SBU personnel is responsible for multiple cases of human rights abuses including sexual violence and torture.[41][42]

A new fifth directorate of SBU was created in 2015 to act as a saboteur force. It was associated with several assassinations of prominent pro-Russian commanders in Donbas: Alexander Zakharchenko, Mikhail Tolstykh and Arsen Pavlov.[43]

On December 21, 2017, two Ukrainian civil servants were arrested by the SBU for spying on behalf of Russia, one of them being an SBU employee while the other, Stanislav Yezhov, worked for various cabinet ministers.[7]

In late 2018, the SBU carried out raids across the country targeting the Ukrainian Orthodox Church (Moscow Patriarchate) churches and priests.[44][45][46]

On July 8, 2019, the SBU announced that they conducted a raid into areas held by the Donetsk People's Republic to apprehend Vladimir Borysovich Tsemakh, who was head of the air defense in Snizhne and a 'person of interest' when a Buk missile launcher was used to shoot down MH17.[47] The SBU mentioned that he's a witness to the incident.[48]

On April 14, 2020, the SBU announced the arrest of Lt. General Valeriy Shaytanov [uk], who was recruited in 2014 by the FSB during a Russian-Ukrainian anti-terrorist working group under the command of Colonel Igor Anatolievich Egorov [uk].[49][50] He was known to head the anti-terrorist division who had played a prominent role in negotiating ceasefires and prisoner exchanges with Russia-backed militants in Eastern Ukraine.[49] He had planned the future assassination of Adam Osmayev, a Chechen in the International Peacekeeping Battalion named after Dzhokhar Dudayev which is defending Ukraine against Russia aggression.[51][52]

2022 Russian invasion of Ukraine

[edit]

With the 2022 Russian invasion of Ukraine, the SBU started to conduct extensive counter-espionage against Russian intelligence services. The SBU captured fifth-columnists, Russian sympathizers, collaborators, spies and infiltrators.[53] The SBU, with help of the American NSA and CIA, also broke through the Russian encrypted cellphone services, intercepting phone calls to find valuable targets or other useful intelligence. Several Russian generals died due to the intercepted calls.[54] They also published many supposed intercepted phone calls on their website, showing morale issues or admissions of war crimes by Russian troops.[55][56]

On March 5, 2022, SBU agents shot and killed Denys Kireyev, a member of Ukraine's negotiating delegation during the 2022 Russian invasion of Ukraine, while he was being arrested.[57] According to the SBU, Kireyev was suspected of treason and was claimed to have clear evidence of him working for the enemy.[58][59] However in August 18, later the Chief Directorate of Intelligence of the Ministry of Defence of Ukraine (GUR) disclosed the information that he was their agent and that he "died while performing special tasks" for the GUR.[60]

On April 12, 2022, the SBU announced they had arrested Viktor Medvedchuk, an ally of Vladimir Putin, in what Bakanov called a "a lightning-fast and dangerous multi-level special operation"; a treason case was opened against Medvedchuk the previous year and in February, and authorities said that Medvedchuk that escaped from house arrest.[61]

On July 17, 2022, Head of the SBU Ivan Bakanov was dismissed by President Volodymyr Zelenskyy.[62] While a long-time associate and personal friend of Zelenskyy, Bakanov was accused of allowing treason and collaboration of SBU agents with Russia, and failing to uproot them.[63][64] Vasyl Malyuk, the first Deputy Head of the SBU, was appointed as acting Head of the SBU.[64] It has been reported that the SBU was in a bad state at the time. The Kherson region SBU head had withdrawn agents before Russia's occupation, against orders. There was nepotism. The SBU was considered to be penetrated by Russian agents; Malyuk prioritised removing them. Malyuk's effectiveness in this was a factor in the success of the 2025 Operation Spiderweb attack on Russian airbases, highly dependent on secrecy, which did not leak.[9]

According to Ukrainska Pravda and the UNIAN, the October 2022 Crimean Bridge explosion was carried out by the SBU.[65][66]

On August 7, 2023, Ukrainian Security Service has arrested a woman in relation to an attempt to assassinate President Zelenskyy. The unnamed woman was accused of supplying information for a Russian air strike.[67]

On August 12, 2024, SBU alleged that Russia was attempting to falsely accuse Kyiv's military of committing war crimes, as Ukraine advanced with a ground incursion into Russia's Kursk region. Meanwhile, Russian state media reported that Alexei Smirnov, accused Ukrainian forces of using chemical weapons. Smirnov also stated that Ukraine had seized control of 28 settlements in the region.[68]

On June 1, 2025, the SBU carried out a massive attack on multiple Russian air bases. The air bases struck were the Belaya air base, the Dyagilevo air base, the Olenya airbase, the Ivanovo airbase, and the Voznesensk airbase. The SBU smuggled in drones in cargo containers into Russia, which were then driven near airbases. The drivers of the trucks carrying the cargo containers were not SBU operatives, but unknowing Russian truckers, with the SBU already having all of their people withdrawn to Ukraine before the attack. When activated, the thin covers of the containers would slid off and the drones would take off and attack the bombers. Video footage shows rows of bombers being destroyed by the drones, causing significant damage to the parked bombers. The attack resulted in the destruction and damage of 41 aircraft, including Tu-95MS and Tu-22M3 strategic bombers, as well as at least one A-50 AWACS aircraft. The damage was valued at an approximate $2 billion, with many of the aircraft destroyed not in production.[69][70][71] On June 3, the SBU carried out an attack on the Crimean Bridge, detonating underwater explosives damaging the bridge support structure.[72]

Assassinations

[edit]

SBU was connected to a number of targeted attacks on Russian military personnel and pro-Kremlin figures. Ukraine said it was behind the killing of a senior Russian naval officer in a car in Crimea. SBU said it was also responsible for the killing of a high-ranking officer in the GRU military intelligence service, who was assassinated outside his house in a village in the Moscow region.

SBU said it assassinated Mikhail Shatsky, a leading Russian missile scientist who worked on upgrading cruise missiles used on the battlefield in Ukraine. His body was discovered in Kuzminsky forest park, at Kotelniki.[73]

In December 2024 the head of the Russian army’s chemical weapons division Igor Kirillov was killed by an explosive device attached to a scooter outside an apartment building in Moscow. It was the most targeted assassination of a senior military official since Russia’s full-scale invasion of Ukraine, according to Guardian.[74][73]

Apart from military figures, Ukraine assassinated Darya Dugina, daughter of Russian ideologue and ultranationalist Aleksandr Dugin, who was killed in August 2022 when a car bomb exploded her Toyota Land Cruiser. The assassination attempt was originally targeted at her father.[75]

Security Service of Ukraine

View on Grokipedia
from Grokipedia
The Security Service of Ukraine (SBU; Ukrainian: Служба безпеки України) is the principal government agency tasked with protecting Ukraine's national security through counterintelligence, counterterrorism, and the defense of state secrets and statehood.[1][2] Established in September 1991 immediately after Ukraine's declaration of independence from the Soviet Union, the SBU succeeded the Ukrainian republic's branch of the KGB, inheriting much of its personnel, infrastructure, and operational framework while undergoing initial reforms to align with the new sovereign state's priorities.[3][4] As a non-military law enforcement body subordinate to the President of Ukraine, the SBU's mandate—formalized by legislation in March 1992—encompasses detecting and preventing threats such as espionage, terrorism, organized crime, and subversion against the constitutional order, with a focus on internal security rather than foreign intelligence gathering.[2][5] The agency maintains regional departments across Ukraine and specialized units, including the Alpha counterterrorism group, and has been central to efforts combating Russian hybrid warfare since the 2014 annexation of Crimea and the ensuing Donbas conflict, neutralizing networks of agents and saboteurs amid ongoing reforms to enhance oversight and reduce politicization inherited from its Soviet-era roots.[6][7] Despite its pivotal role in safeguarding sovereignty, the SBU has faced criticism for past inefficiencies and alleged ties to oligarchic influences, prompting legislative pushes for modernization to prioritize apolitical counterintelligence functions.[8][9]

Legal Basis and Mandate

Establishment and Legal Framework

The Security Service of Ukraine (SBU; Ukrainian: Sluzhba bezpeky Ukrayiny) was established on September 20, 1991, through a resolution of the Verkhovna Rada of Ukraine, shortly following the country's declaration of independence from the Soviet Union on August 24, 1991.[10] [4] This creation transformed the republican branch of the KGB of the USSR into a national agency aligned with Ukraine's sovereignty, retaining much of the prior personnel and infrastructure while initiating a reorientation away from Soviet structures.[6] The foundational legal framework was codified in the Law of Ukraine "On the Security Service of Ukraine," enacted by the Verkhovna Rada on March 25, 1992.[4] [11] This statute delineates the SBU as a special-purpose state body with law enforcement functions, classified as a state authority organ, and as a state security body with military status, directly subordinated to the President of Ukraine, and empowered to conduct counterintelligence, counter-subversion, and protective operations to safeguard national security, territorial integrity, and the constitutional order.[11] Article 4 of the law specifies that its activities are grounded in the Constitution of Ukraine, this legislation, international treaties ratified by Ukraine, and other pertinent normative acts.[11] The Constitution of Ukraine, particularly Article 17, reinforces the SBU's role as the primary agency coordinating state security efforts, ensuring the defense of democracy, human rights, and freedoms against internal and external threats.[12] Subsequent amendments to the 1992 law, including provisions for operational independence and oversight mechanisms, have refined its mandate, though core principles of presidential subordination and focus on non-criminal intelligence functions persist.[13] The SBU's military character grants its personnel ranks and status akin to armed forces members, distinguishing it from civilian law enforcement.[11]

Core Duties and Responsibilities

The core duties and responsibilities of the Security Service of Ukraine (SBU) are outlined in the Law of Ukraine "On the Security Service of Ukraine" No. 2229-XII, enacted on March 25, 1992, and subsequently amended, including as recently as July 16, 2025.[11] This legislation establishes the SBU as a state law enforcement and intelligence agency tasked primarily with safeguarding national security through counterintelligence measures. Its mandate emphasizes protection against external threats, including the prevention, detection, suppression, and investigation of subversive activities by foreign intelligence services, organizations, or individuals aimed at undermining Ukraine's sovereignty, constitutional order, territorial integrity, or defense capabilities.[11] [4] Key responsibilities include combating terrorism by identifying and neutralizing threats to public safety and state institutions, as well as countering organized crime that poses risks to national security, such as large-scale embezzlement of state funds or corruption enabling foreign influence.[11] [4] The SBU is also charged with protecting state secrets, including scientific-technical and economic information vital to national defense, through measures like vetting personnel and securing classified materials.[11] In addition, it conducts information-analytical support for government bodies, providing assessments on security threats to inform policy decisions.[4] Amid the ongoing Russian invasion, legislative updates have expanded the SBU's operational scope, authorizing enhanced special operations to counter armed aggression, including targeted strikes on enemy assets and military counterintelligence within the Armed Forces of Ukraine.[14] [15] As of July 28, 2025, President Volodymyr Zelensky signed a law increasing SBU personnel and capabilities to bolster these defensive activities, reflecting adaptations to wartime exigencies while retaining the foundational counterintelligence focus.[14] Despite reform proposals to narrow its role exclusively to counterintelligence and eliminate general law enforcement functions—such as reducing staff from approximately 27,000 to 15,000 and ending pre-trial investigations—these changes remain unimplemented as of October 2025, preserving the agency's broader mandate.[16]

Organizational Structure

Internal Divisions and Hierarchy

The Security Service of Ukraine (SBU) operates under a hierarchical structure determined by the President of Ukraine, with the Chairman at the apex, appointed directly by the president and responsible for overall command and coordination. The Chairman is supported by an Apparatus that handles executive functions, policy implementation, and oversight of subordinate units. Deputy chairmen and department heads report to the Chairman, forming a centralized chain of command that emphasizes operational secrecy and rapid decision-making in counterintelligence and security matters. This structure, while evolved from Soviet-era models, prioritizes functional specialization to address threats like espionage, terrorism, and subversion. The SBU and Russia's Federal Security Service (FSB) are successor agencies to the KGB, with the SBU inheriting the Ukrainian SSR branch and the FSB the Russian; direct quantitative comparisons remain limited.[17][18] The Central Office constitutes the core of the SBU, encompassing specialized departments for core missions. Key operational departments include the Department of Counterintelligence, focused on detecting and neutralizing foreign intelligence activities; the Department of Military Counterintelligence, which embeds units within the armed forces to counter espionage and internal threats; the Department of Protection of National Statehood, targeting subversion against Ukraine's sovereignty; and the Center for Special Operations "A" (commonly known as Alpha Group), a department-status unit specializing in high-risk operations, counterterrorism raids, and hostage rescue, with training in advanced tactics such as sniping and parachuting. Investigative and support functions are handled by the Main Investigative Department for pretrial probes into security crimes, the Main Department of Internal Security for auditing SBU personnel, and departments for economic counterintelligence, state secrets protection, operational-technical measures (e.g., surveillance), and special communications. Analytical and administrative units, such as the Department of Information and Analytical Support, Personnel Management Department, Legal Support Department, and Financial and Economic Department, ensure logistical and strategic backing.[17][19][18] Regional organs extend the SBU's reach, comprising main departments in major areas (e.g., Kyiv and Kyiv Oblast, pre-2014 Crimea) and dedicated departments in each oblast (e.g., Vinnytsia, Lviv, Kharkiv) plus Sevastopol, totaling over 20 territorial units for localized surveillance, recruitment, and response. Military counterintelligence bodies operate as embedded subunits rather than standalone regions, integrated into military commands to monitor troops and defense infrastructure. The Antiterrorist Center, functioning directly under the SBU, coordinates interagency efforts against terrorism, drawing on Alpha units and regional assets for unified operations. Training and research are supported by institutions like the National Academy of the SBU for officer education and the Ukrainian Research Institute of Special Equipment and Forensic Examinations for technical development.[17][19] Authorized personnel stood at approximately 30,000 focused on counterintelligence against Russian threats in peacetime under 2005 provisions, expandable in special periods and further under wartime mobilization, with the Alpha Center maintaining at least 10,000 operatives and the FSB estimated at 200,000 staff handling broader internal security. The structure has undergone incremental reforms, including separations of foreign intelligence (into an independent service in 2004) and government communications, but retains KGB-like centralization with limited public transparency on exact hierarchies due to operational sensitivities. A 2025 reform law signed by President Zelenskyy introduced enhancements to the organizational framework and personnel welfare, aligning with NATO-inspired standards amid ongoing wartime adaptations, though detailed divisional reallocations are not publicly specified.[19][18][20]

Personnel, Training, and Resources

The Security Service of Ukraine (SBU) maintains an authorized peacetime personnel strength of approximately 30,000 focused on counterintelligence against Russian threats.[21][22] This expansion allocates additional staff primarily to the Special Operations Center "A" (Alpha Group) and other counterterrorism units, with wartime staffing permitted up to higher levels to address heightened threats from Russian intelligence activities.[23] Actual deployment figures remain classified amid the ongoing conflict, but the agency recruits through competitive processes emphasizing physical fitness, psychological resilience, and specialized skills for roles in counterintelligence, cyber operations, and field operations.[24] Training occurs primarily at the National Academy of the Security Service of Ukraine (NASBU), a higher education institution reorganized from earlier KGB-era facilities to prepare officers in counterintelligence, special operations, and national security disciplines. Its rector is appointed by the President of Ukraine.[25] The curriculum has shifted toward practical components, including hands-on simulations, foreign partner exchanges, and large-scale special operations drills, with recent enhancements in cybersecurity training via dedicated centers established in collaboration with international organizations.[26][27] Specialized units like Alpha undergo rigorous selection involving physical tests, marksmanship, tactical maneuvers, and loyalty vetting, often drawing from military veterans or academy graduates to ensure operational readiness against hybrid threats.[24][28] Resources for the SBU are drawn from Ukraine's state budget within the broader security and defense sector, which totaled approximately UAH 1.85 trillion in 2023 for all agencies.[29] In 2025, the SBU received an additional UAH 1.6 billion (about $40 million) amid budget amendments to bolster wartime capabilities, funding personnel expansion, equipment procurement, and operational sustainment.[30] While detailed allocations for assets like surveillance technology, armored vehicles, and weaponry are not publicly itemized due to security sensitivities, the agency's resources have been augmented by Western intelligence-sharing partnerships rather than direct matériel transfers, prioritizing human intelligence and domestic production amid fiscal constraints.[6]

Historical Development

Soviet-Era Predecessors and Transition

The Committee for State Security (KGB) of the Ukrainian Soviet Socialist Republic operated as the primary internal security organ in Soviet Ukraine from its formal establishment in 1954 until 1991, functioning as a republican affiliate of the all-Union KGB headquartered in Moscow.[4] Its core responsibilities included counterintelligence against foreign espionage, surveillance and suppression of political dissent, protection of state secrets, and combating perceived anti-Soviet activities such as Ukrainian nationalism or ideological subversion, often through infiltration, arrests, and archival documentation of suspects.[31] These operations aligned with the broader KGB mandate to maintain Communist Party control and ideological conformity across the USSR, contributing to the incarceration or exile of thousands of Ukrainian intellectuals, cultural figures, and activists during periods like the 1960s-1980s "dissident crackdowns."[32] Ukraine's push for independence accelerated following the failed August 1991 coup attempt against Mikhail Gorbachev in Moscow, which weakened central Soviet authority. On August 24, 1991, the Verkhovna Rada declared Ukraine's sovereignty, prompting immediate steps to nationalize security institutions. By September 20, 1991, the Rada adopted a resolution dissolving the KGB of the Ukrainian SSR and enacting the Law "On the Service of National Security of Ukraine," which created the Security Service of Ukraine (SBU) as an independent agency subordinated solely to the Ukrainian state rather than Moscow.[33] [8] This legislation emphasized the SBU's role in defending Ukraine's constitutional order, territorial integrity, and countering threats like espionage or subversion, explicitly barring it from internal political repression or economic functions previously handled by the KGB.[4] The transition involved reorganizing existing KGB structures, with the SBU inheriting approximately 90% of the republican KGB's personnel—around 25,000-30,000 officers and staff—as well as regional offices, archives, and equipment, enabling operational continuity amid the USSR's collapse.[34] Nikolai Golushko, the final KGB chairman in Ukraine, served as acting SBU head from September 20 to November 6, 1991, overseeing the initial purge of overtly pro-Moscow elements while retaining most mid-level operatives due to expertise shortages.[34] Yevhen Marchuk, a career KGB officer with experience in counterintelligence, then became the first permanent chairman in late 1991 (confirmed in early 1992), prioritizing loyalty oaths to Ukraine and gradual de-Sovietization, though entrenched personnel ties delayed full ideological decoupling and fueled early criticisms of residual authoritarian methods.[35] This inheritance ensured the SBU's rapid functionality but embedded challenges, including potential infiltration risks from Soviet-era networks still aligned with Russia.[4]

Early Independence Period (1991–2004)

The Security Service of Ukraine (SBU) was established on September 20, 1991, through a resolution of the Verkhovna Rada that transformed the republican structures of the KGB of the Ukrainian SSR into a national agency focused on counterintelligence, protection of state secrets, and combating threats to sovereignty amid Ukraine's declaration of independence earlier that year.[8] Initially named the National Security Service of Ukraine, it inherited approximately 25,000 personnel from the KGB but prioritized restructuring to align with democratic principles, including the adoption of the Law on the Security Service of Ukraine in March 1992, which defined its mandate to exclude internal political repression and emphasize external threats like espionage.[34] Yevhen Marchuk, appointed chairman on November 6, 1991, led initial efforts to assert loyalty to the new state, dismissing pro-Soviet elements and redirecting operations toward safeguarding independence against residual Soviet influences.[34] Under Marchuk's tenure until July 1994, the SBU conducted counterintelligence operations to neutralize foreign agents exploiting Ukraine's post-Soviet vulnerabilities, including a 1994 case involving the apprehension of Swedish national Eric Olaf Estenson for provocative activities aimed at destabilizing the country.[4] The agency also addressed organized crime and economic sabotage during hyperinflation and privatization chaos, with counterintelligence units targeting smuggling networks and corruption that threatened fiscal stability. Successors like Volodymyr Radchenko (1994–1997) expanded focus on economic security, establishing departments to combat financial crimes and protect critical infrastructure, though personnel shortages—reduced to around 15,000 by mid-decade—limited effectiveness.[34] Russian intelligence penetration remained a core concern, with SBU uncovering networks linked to Moscow seeking to influence politics and military assets, such as the Black Sea Fleet division agreements.[8] By the late 1990s under Leonid Derkach (1997–2000), the SBU faced accusations of overreach, including selective enforcement favoring President Leonid Kuchma's administration, which eroded public trust inherited from the KGB's repressive legacy.[34] The 2000 investigation into journalist Heorhii Gongadze's murder highlighted operational shortcomings, with evidence mishandling prompting Kuchma to dismiss Derkach in 2001 amid tapes alleging high-level involvement.[8] Vladimir Maliarenko's interim leadership (2000–2003) and subsequent appointments attempted professionalization, but persistent challenges included inadequate funding—budgets hovered below 0.5% of GDP—and infiltration risks from former Soviet operatives, fostering perceptions of the SBU as a tool for elite protection rather than impartial security.[34] Through 2004, the agency dismantled several espionage rings tied to Russia and Belarus, yet systemic ties to old guard personnel hindered full de-Sovietization.[4]

Post-Orange Revolution Reforms (2005–2010)

Following the Orange Revolution, President Viktor Yushchenko sought to reform the Security Service of Ukraine (SBU) by removing holdovers from the Kuchma administration and shifting the agency toward greater accountability and reduced political interference. On February 4, 2005, Yushchenko dismissed SBU Chairman Ihor Smeshko, a career intelligence officer appointed in 2003, citing the need to break from past practices that included alleged complicity in electoral manipulations.[36] Yushchenko then appointed Oleksandr Turchynov, a civilian politician and ally from the Our Ukraine bloc, as the new chairman—the first non-military figure to lead the SBU since Ukraine's independence—tasking him with purging corrupt elements and investigating 2004 election fraud, including falsified vote counts estimated at over 1.5 million by international observers.[37] [38] Turchynov's leadership initiated probes into high-profile cases, such as the poisoning of Yushchenko with dioxin in late 2004, but yielded few convictions due to evidentiary challenges and resistance from entrenched networks.[38] Turchynov served until September 8, 2005, when Yushchenko removed him amid scandals involving alleged SBU misconduct, including unauthorized surveillance and internal leaks, which highlighted ongoing institutional opacity.[38] Subsequent appointments, such as acting or interim heads, reflected political instability, with the SBU remaining contested terrain amid coalition disputes between Yushchenko's supporters and Viktor Yanukovych's allies. On November 7, 2005, Yushchenko issued a decree establishing the independent State Service of Special Communications and Protection of Information, carving out the SBU's government communications and signals protection units to streamline functions and limit the agency's domestic reach, though this separation did not address broader counterintelligence overlaps.[18] Efforts to institutionalize reforms continued unevenly; in December 2006, Yushchenko proposed a National Commission on Reforming the SBU to develop a comprehensive strategy, emphasizing depoliticization and alignment with Euro-Atlantic standards, but the initiative stalled amid parliamentary gridlock and lack of unified presidential-parliamentary support.[39] Throughout 2005–2010, the SBU's personnel numbered around 25,000–30,000, with budgets fluctuating between 1.5–2 billion hryvnia annually, yet persistent corruption—manifest in economic crime investigations that often protected elite interests—and ties to regional clans undermined progress, as evidenced by internal audits revealing embezzlement cases exceeding 100 million hryvnia yearly.[39] No major amendments to the 1992 Law on the Security Service of Ukraine were enacted during this period, leaving the agency's expansive mandate intact and vulnerable to executive influence.[13] By 2010, these half-measures had failed to fully sever Soviet-era legacies, positioning the SBU as a tool in domestic power struggles rather than a reformed guardian of national security.[39]

Yanukovych Administration (2010–2014)

Upon Viktor Yanukovych's inauguration as president on February 25, 2010, the Security Service of Ukraine (SBU) underwent leadership changes aligning it more closely with the new administration's priorities. On March 11, 2010, Yanukovych appointed oligarch Valeriy Khoroshkovsky, a media magnate and owner of the Inter Media Group controlling significant television assets, as SBU head.[40] Khoroshkovsky's tenure, lasting until January 2012, saw the agency revert to Soviet-era tactics, including intimidation and surveillance of critics, drawing accusations of politicization to protect regime interests over national security.[41] The SBU under Khoroshkovsky investigated high-profile opposition figures, such as former Prime Minister Yulia Tymoshenko on charges related to a 2009 gas deal with Russia, amid broader efforts to consolidate power through selective prosecutions.[42] Khoroshkovsky's dismissal on January 19, 2012, and subsequent appointment as finance minister marked a transitional phase, with interim leadership including figures like Ignat Danilchenko before a permanent replacement.[43] On January 9, 2013, Yanukovych elevated Oleksandr Yakymenko, a former air force general with ties to Russian-oriented security circles, to SBU chief.[44] Yakymenko's leadership intensified the agency's domestic focus, including expanded authority under a January 2012 law signed by Yanukovych to probe "mass disturbances" and official abuse of power, facilitating preemptive suppression of dissent.[45] This period also involved interference in media and business spheres, with SBU actions supporting allied oligarchs while targeting competitors, as evidenced by probes into outlets critical of the regime.[46] The Yanukovych administration's pro-Russian pivot compromised SBU counterintelligence efforts against Moscow. Despite internal warnings—at least twice in 2010 and 2011 about Russian subversion in Crimea—the agency was directed to deprioritize such threats, allowing unchecked FSB activities on Ukrainian soil.[47] SBU operations against pro-Russian separatists were explicitly prohibited, enabling Russian agents freer rein and contributing to later vulnerabilities in 2014.[47] Resources shifted toward internal surveillance, including against journalists and activists, as in the 2011 case of blogger Oleg Shinkarenko targeted for anti-Yanukovych posts, exemplifying the service's weaponization for political loyalty over external defense.[6] As Euromaidan protests escalated from November 2013, the SBU under Yakymenko played a supporting role in regime security measures, conducting surveillance and coordinating with other forces amid violent crackdowns that killed over 100 demonstrators by February 2014.[48] Yakymenko fled to Russia following Yanukovych's ouster on February 22, 2014, later facing treason charges for alleged collaboration that undermined Ukrainian sovereignty.[49] This era's emphasis on regime protection eroded institutional independence, fostering infiltration by Russian assets and setting the stage for post-Maidan reforms.

Euromaidan Revolution and Reorientation (2014–2021)

During the Euromaidan Revolution, from November 2013 to February 2014, the Security Service of Ukraine (SBU) under head Oleksandr Yakymenko, a close ally of President Viktor Yanukovych, played a role in suppressing protests against the government's suspension of EU association talks. Investigations later revealed coordination with Russia's Federal Security Service (FSB), including the presence of at least 20 FSB officers in Kyiv from December 13 to 15, 2013, to assist in planning the crackdown on demonstrators.[50] On February 19, 2014, amid escalating violence, the SBU announced an "anti-terrorist operation" targeting protesters, which contributed to the deaths of over 100 civilians in clashes with security forces.[51] Following Yanukovych's flight to Russia on February 22, 2014, and the Revolution of Dignity's success, the SBU underwent immediate leadership changes and internal purges to excise pro-Russian elements. Valentyn Nalyvaichenko was appointed acting head on February 24, 2014, reporting that SBU headquarters had been stripped of files and weapons by fleeing personnel.[52] The agency, previously infiltrated by Russian agents, initiated arrests of suspected collaborators; by late 2014, it had detained 235 individuals accused of espionage for Moscow and charged unspecified numbers of its own officers with treason.[53] Vasyl Hrytsak succeeded Nalyvaichenko as head in June 2015, overseeing a shift toward countering hybrid threats amid Russia's annexation of Crimea in March 2014 and the outbreak of war in Donbas that April.[6] The SBU's reorientation emphasized counterintelligence against Russian operations, including in the Anti-Terrorist Operation (ATO) framework for Donbas from 2014 to 2018, where it coordinated security efforts against separatist forces backed by Moscow.[54] Key activities involved dismantling FSB agent networks, such as a 2021 exposure of Ukrainian citizens recruited for intelligence tasks in eastern regions, and documenting early Wagner Group deployments in Donbas from May 2014.[55][56] Reforms progressed unevenly; a 2019 law curtailed the SBU's involvement in economic crimes to refocus on state security and hybrid warfare, though critics noted persistent corruption, political misuse, and insufficient depoliticization.[6][57] By 2021, under ongoing leadership, the agency had foiled numerous espionage attempts but retained broad domestic powers, reflecting incomplete transition from its Soviet-era roots despite external pressures for Western-aligned oversight.[58]

Full-Scale Russian Invasion Era (2022–Present)

The Security Service of Ukraine (SBU) shifted to a wartime posture following Russia's full-scale invasion on February 24, 2022, prioritizing counterintelligence, sabotage against Russian forces, and neutralization of internal collaborators. Prior to the invasion, the agency had disrupted several Russian intelligence-gathering operations targeting Ukrainian military assets, including attempts to recruit insiders for sabotage. In the invasion's early stages, SBU elements supported the defense of Kyiv by identifying and arresting suspected Russian agents and local collaborators, contributing to the disruption of planned terrorist acts in government-controlled areas. By August 2025, the SBU reported exposing 207 Russian operatives since the invasion's outset, among them 52 active-duty Ukrainian servicemen acting as moles.[59][58] Leadership transitioned amid scrutiny of internal loyalties. President Volodymyr Zelenskyy dismissed SBU head Ivan Bakanov in July 2022, citing widespread treason cases within the security apparatus that compromised operations during the invasion's initial months. Vasyl Maliuk, a lieutenant general with prior counterintelligence experience, assumed the role of acting head and was formally appointed on February 7, 2023. Under Maliuk, the SBU expanded cross-border operations, conducting sabotage deep inside Russian territory, including drone strikes on military airfields and the assassination of a pro-Russian paramilitary leader in Moscow on February 3, 2025. Maliuk personally oversaw responses to targeted killings, such as the July 2025 elimination of a foreign hit squad in Kyiv after the murder of an SBU colonel.[4][60][61] The SBU claimed responsibility for the October 8, 2022, truck bombing of the Kerch Bridge linking Russia to occupied Crimea, which damaged the structure and disrupted Russian logistics. Subsequent operations included maritime drone strikes across the Black Sea, with an upgraded "Sea Baby" variant unveiled in October 2025 capable of operating throughout the sea and carrying heavier payloads. In June 2025, Maliuk disclosed details of an 18-month effort involving 117 drones and 2,200 kg of explosives to destroy Russian strategic bombers, followed by "Operation Cobweb," a drone swarm attack postponed due to Russian logistical delays during Easter. Internally, the agency detained its own counter-terrorism center chief in February 2025 on suspicion of Russian collaboration, highlighting ongoing infiltration risks.[5][62][63] Wartime demands prompted resource reallocations, with SBU personnel integrated into broader defense efforts, though specific reforms remained limited amid the conflict's exigencies. By October 2025, Maliuk reported to Zelenskyy on enhanced long-range strike capabilities and operational plans targeting Russian advances, such as in the Pokrovsk direction, underscoring the agency's evolving role in asymmetric warfare. These activities, while boosting Ukrainian morale, relied heavily on unverified Ukrainian disclosures, with Russian sources denying many claims of damage or attributing successes to defensive measures.[64][65][66]

Key Operations and Achievements

Counterintelligence and Sabotage Against Russia

The Security Service of Ukraine (SBU) has prioritized counterintelligence measures to detect and dismantle Russian intelligence networks within Ukraine following the full-scale invasion on February 24, 2022. By August 2025, the SBU reported exposing 207 Russian agents and spies operating across various sectors, including adjustments to recruitment tactics amid heightened scrutiny.[67][59] Among these, 52 individuals were identified as active-duty personnel in the Ukrainian Armed Forces, with 44 convicted and sentenced to 12–15 years in prison for treason and espionage.[67] These efforts have included neutralizing embedded agents who leaked military plans, such as a former Special Operations Forces commander arrested in 2024 possessing encrypted devices with sensitive warfare data.[67] Specific counterintelligence operations have targeted Russian military intelligence (GRU) cells responsible for coordinating strikes and sabotage. In February 2025, the SBU detained two agents in Kyiv and Odesa—a 27-year-old Kyiv resident and a 40-year-old former serviceman—linked to GRU handler Maksim Chachin, who directed scouting of strategic sites for missile and drone attacks on Kyiv via Google Maps coordinates.[68] The network, recruited through a former Kyiv university lecturer who fled to Russia in 2021, also executed arson on two mobile communication towers and electrical substations in Odesa while preparing IED-based terrorist acts, all of which were thwarted.[68] The suspects face life imprisonment on charges of high treason, sabotage, and explosives handling. Additional arrests in July 2025 involved a Kharkiv-based agent plotting substation bombings, and on August 11, 2025, a Lviv woman spying on airfields via concealed cameras.[67][67] In parallel, the SBU has conducted sabotage operations targeting Russian military and infrastructure assets, often deep within Russian territory or occupied areas, as claimed by SBU head Vasyl Maliuk. On October 8, 2022, the SBU detonated a truck bomb on the Kerch Bridge, destroying a road section and damaging rail lines, disrupting Russian logistics for seven months.[69] Assassinations included Daria Dugina via car bomb in Moscow on August 20, 2022; Vladlen Tatarsky with an explosive figurine in St. Petersburg on April 2, 2023; Lt. Gen. Igor Kirillov by scooter bomb in December 2024; and Lt. Gen. Yaroslav Moskalik by car bomb in April 2025.[69] Infrastructure strikes encompassed explosives on the Baikal-Amur Mainline railway in Siberia on November 30, 2023, igniting a freight train and damaging a bridge; underwater mines weakening Kerch Bridge supports on June 3, 2024; and drone strikes destroying approximately 12 military aircraft at Russian airfields on June 1, 2024, via smuggled containers.[69] These actions, executed with local assets and remote activation, aimed to degrade Russian operational capacity, though Russian sources often dispute attributions and casualty figures.[69] In 2026, the SBU reported neutralizing multiple FSB agents involved in sabotage, highlighting ongoing operational rivalry.[70]

Naval and Drone Operations

The Security Service of Ukraine (SBU) has played a central role in asymmetric naval warfare against Russia's Black Sea Fleet since the full-scale invasion in February 2022, primarily through the deployment of unmanned surface vessels (USVs) known as "Sea Baby" drones. These maritime drones, developed and operated under SBU oversight, have been used to conduct strikes on Russian naval assets and infrastructure, contributing to the degradation of Russian naval presence in the region. The SBU has credited these operations with forcing Russia to relocate significant portions of its fleet from Sevastopol and other Crimean bases to more distant ports like Novorossiysk.[71][72] On October 22, 2025, the SBU unveiled an upgraded iteration of the Sea Baby drone, featuring enhanced range exceeding 1,000 kilometers, reinforced engines, improved navigation systems, and capacity for heavier explosive payloads, enabling operations across the entire Black Sea. The agency reported that prior versions of these USVs had successfully struck 11 Russian vessels, including frigates and missile carriers, since the war's onset, with strikes targeting anchored ships and port facilities to exploit Russian vulnerabilities in defended harbors. These drone operations rely on remote control, satellite guidance, and explosive warheads, allowing low-cost, high-impact attacks that bypass traditional naval superiority.[72][71][73] In coordination with the Ukrainian Navy, the SBU executed a joint strike on October 18, 2025, destroying a key Russian ammunition depot at Kinburn Spit near the Black Sea entrance to the Dnipro River, which disrupted logistics for Russian forces in southern Ukraine and enhanced Ukrainian control over vital shipping routes. SBU-led sabotage efforts have also incorporated underwater elements, such as a reported June 2025 operation targeting the Kerch Bridge connecting Russia to occupied Crimea, using divers and submersible devices to damage underwater supports and interrupt supply lines. SBU Head Vasyl Maliuk stated that these naval drone initiatives would persist to systematically expel Russian naval forces from the Black Sea, reflecting a shift toward unmanned systems as a force multiplier in Ukraine's resource-constrained maritime domain.[74][75]

Cyber and Domestic Security Efforts

The Security Service of Ukraine (SBU) maintains a dedicated Cyber Security Department responsible for defending against Russian-sponsored cyberattacks and hybrid threats, particularly intensified since the February 2022 invasion. SBU cyber teams conduct real-time operations to disrupt Russian drone incursions, utilizing proprietary drones, sensors, and electronic warfare tactics in a continuous adversarial cycle along front lines.[76] Ukrainian officials, including SBU leadership, have stressed the imperative of national cyber resilience, implementing layered defenses to mitigate disruptions to critical infrastructure amid persistent Russian probing.[77] In parallel, SBU cyber efforts integrate with broader information operations, countering Russian influence campaigns and malware deployments targeting government and military networks, as evidenced by joint advisories from Western agencies on GRU-linked activities.[78] These operations have contributed to Ukraine's overall cyber posture, enabling sustained functionality of digital systems under duress, though specific attribution of prevented incidents remains classified.[79] Domestically, SBU prioritizes counter-sabotage and counterintelligence to neutralize FSB-orchestrated networks, arresting hundreds of collaborators since 2022 through vetting, surveillance, and raids. By August 2025, the agency had exposed 207 Russian spies across military units, political circles, and infrastructure sites, including a marine brigade operative directing strikes on Ukrainian bases and an air force officer leaking data on Western-supplied jets.[59][80][81] SBU's 2023 counter-sabotage measures vetted nearly 1 million individuals, averting threats at nuclear facilities in Mykolaiv, Rivne, and Khmelnytskyi regions by detaining 13 suspected agents.[82] High-profile actions include the November 2022 raid on Kyiv's Kievo-Pechersk Lavra monastery, targeting alleged Russian subversive cells, and January 2025 arrest of an engineer heading a spy ring coordinating attacks on energy grids.[83][84] The agency has also exposed impersonation tactics where Russian operatives pose as SBU officers via fake summonses to recruit civilians for sabotage, issuing public warnings to disrupt such recruitment.[85] These efforts have demonstrably reduced internal threats, with SBU documenting prevention of dozens of planned diversions at rail, port, and power facilities.[58]

Controversies and Criticisms

Domestic Surveillance and Political Overreach

The Security Service of Ukraine (SBU) has been implicated in unauthorized surveillance operations targeting domestic actors, including journalists and civil society figures, often justified under national security pretexts but criticized as exceeding legal bounds. In early 2024, the investigative outlet Bihus.Info disclosed that SBU agents had installed hidden cameras and recording devices in the journalists' offices, vehicles, and residences for months, capturing private conversations unrelated to security threats.[86] This surveillance culminated in a leaked video in January 2024 purporting to depict Bihus.Info staff using narcotics at a New Year's event, which the outlet attributed to a failed SBU smear campaign; the incident sparked outrage over press freedoms, with G7 ambassadors engaging journalists to investigate.[87] President Volodymyr Zelenskyy responded by dismissing the head of the SBU's Department of Operational Support, though the agency denied systematic wrongdoing and claimed the recordings targeted potential corruption.[88] SBU actions have extended to political figures perceived as oppositional, particularly those with pro-Russian ties, raising allegations of selective enforcement to neutralize rivals. In May 2021, the SBU raided the home of Opposition Platform—For Life leader Viktor Medvedchuk, charging him with treason for allegedly financing separatist groups in Donbas with over 200 million hryvnia (approximately $7.5 million USD at the time); Medvedchuk, a close associate of Russian President Vladimir Putin, denounced the probe as "political repression" aimed at silencing dissent.[89] The SBU's investigation preceded National Security and Defense Council sanctions in February 2021 blocking three Medvedchuk-linked television channels—112 Ukraine, ZIK, and NewsOne—on grounds of spreading Russian propaganda and evading prior sanctions, affecting an estimated 6 million viewers and prompting accusations from opposition lawmakers of media censorship to consolidate power.[90] Under martial law enacted in February 2022, the SBU's surveillance mandate expanded, permitting warrantless interceptions in counterintelligence cases, but instances of overreach persisted into 2025 amid inter-agency conflicts. The SBU launched raids on the National Anti-Corruption Bureau of Ukraine (NABU) in July 2025, detaining at least one employee on high treason charges for purported Russian ties, including alleged coordination with FSB handlers; these operations, involving over 70 searches, coincided with NABU probes into scandals implicating Zelenskyy allies, fueling claims that the SBU—viewed as aligned with the President's Office—was weaponized to obstruct anti-corruption efforts.[91] [92] Independent analyses have highlighted how such clashes erode institutional independence, with the SBU portraying targets as security risks while critics argue the timing reflects political self-preservation rather than genuine threats.[93] Zelenskyy administration defenders counter that wartime exigencies necessitate aggressive domestic monitoring to counter infiltration, though documented illegal tactics like the Bihus case underscore accountability gaps in SBU oversight.[94]

Human Rights Violations and Due Process Issues

The Security Service of Ukraine (SBU) has faced documented allegations of human rights violations, particularly arbitrary detentions, enforced disappearances, and torture, primarily in the context of countering separatist activities in eastern Ukraine since 2014. A joint report by Human Rights Watch and Amnesty International, based on interviews with 40 victims, detailed nine cases of arbitrary and prolonged detentions by Ukrainian authorities, including three involving SBU facilities where detainees were held in secret for periods ranging from six weeks to 15 months without acknowledgment of their custody or access to legal representation.[95][96] These incidents occurred in SBU premises in Kharkiv, Kramatorsk, Izyum, and Mariupol, with victims subjected to beatings, electric shocks, waterboarding, and threats of execution to extract confessions of separatist ties.[95] A United Nations Office of the High Commissioner for Human Rights (OHCHR) thematic report covering April 2014 to April 2021 verified approximately 2,300 arbitrary detentions by Ukrainian government actors, including the SBU, out of 3,600–4,000 total conflict-related detentions, with around 1,500 victims reporting torture or ill-treatment such as electrocution, sexual violence, and mock executions.[97] Secret and incommunicado detentions were prevalent in unofficial SBU sites, especially during 2014–2015 when 60% of arbitrary cases occurred, often without court warrants or notification to families, facilitating coerced statements and denying detainees medical care for injuries.[97] Specific patterns included transferring detainees to conceal their presence during international inspections, as in cases from November 2014 and May 2016 at the Kharkiv SBU facility.[97] Due process violations have compounded these abuses, with detainees routinely denied prompt judicial review, legal counsel, or evidence presentation, contravening Ukrainian law and international standards.[95] In 2023, the OHCHR documented 65 instances of SBU incommunicado detentions in unofficial facilities lasting hours to 4.5 months, aimed at coercing information related to alleged Russian collaboration, during which 57% of interviewees reported torture or ill-treatment.[98] The U.S. Department of State noted that such practices persisted under martial law, with SBU withholding information from relatives and ignoring court authorizations for release in some cases.[98] Investigations into these allegations have been limited, contributing to patterns of impunity, as few perpetrators faced prosecution despite victim testimonies and forensic evidence of abuse.[97][99]

Corruption Scandals and Internal Misconduct

In September 2025, Ukraine's National Anti-Corruption Bureau (NABU) and Specialized Anti-Corruption Prosecutor's Office (SAPO) notified Illia Vitiuk, the former head of the Security Service of Ukraine's (SBU) cybersecurity department, of suspicion for illicit enrichment and submitting false asset declarations; the case alleges discrepancies between his declared income and acquired properties, including luxury vehicles and real estate valued at millions of hryvnias.[100] The SBU dismissed the charges as retaliatory "revenge" by anti-corruption agencies amid ongoing inter-agency tensions, claiming Vitiuk's ouster in 2024 was unrelated to personal gain but part of broader restructuring.[101] Also in September 2025, NABU and SAPO indicted a senior SBU officer and two accomplices for extorting $300,000 from an individual to quash evidence in a scheme smuggling military-age men abroad to evade mobilization; the case, involving wiretaps and surveillance footage, was forwarded to court, with potential penalties of up to 12 years imprisonment and asset forfeiture.[102] This incident highlighted alleged abuse of SBU operational tools for personal profit, tied to Ukraine's wartime border control challenges where smuggling networks have proliferated.[103] In July 2025, NABU charged another SBU officer with bribery, accusing him of soliciting payments to influence investigations; the suspect faces up to 12 years in prison, amid escalating raids and counter-accusations between the SBU and NABU over alleged Russian infiltration in anti-corruption probes.[104] These cases reflect persistent internal vulnerabilities, despite SBU reforms post-2014, including the unexplained 2022 disbandment of Department "K," its organized crime and anti-corruption unit, which critics linked to operational failures or self-protection from scrutiny.[6] Earlier probes, such as those against former SBU head Vasyl Hrytsak (2015–2020), involved court orders for NABU to investigate undeclared family asset acquisitions and potential treason, but yielded no convictions and were marred by claims of political motivation during leadership transitions.[105][106] Overall, while wartime priorities have limited systemic audits, individual misconduct prosecutions underscore challenges in insulating the SBU from graft, with inter-agency rivalries complicating accountability.[107]

Conflicts with Anti-Corruption Bodies

The Security Service of Ukraine (SBU) has engaged in multiple public disputes with the National Anti-Corruption Bureau of Ukraine (NABU) and the Specialized Anti-Corruption Prosecutor's Office (SAPO), primarily over jurisdiction in high-profile investigations and allegations of mutual interference. These conflicts intensified in 2025, with the SBU conducting raids on NABU and SAPO facilities, detaining personnel, and accusing anti-corruption officials of ties to Russian intelligence, while NABU and SAPO countered by charging SBU officers with corruption and portraying the actions as efforts to shield politically connected figures.[108][94][91] On July 21, 2025, the SBU initiated searches targeting individuals it claimed exerted "significant influence" on NABU activities, alleging contacts with Russian intelligence and potential sabotage of national security probes under the guise of anti-corruption work. The operation included detaining a senior investigator linked to SAPO, whom the SBU accused of leaking sensitive information, though NABU and SAPO described the moves as a "coordinated assault" to undermine their independence and obstruct cases involving defense procurement and elite networks.[92][109][110] In response, on September 4, 2025, NABU filed charges against Illia Vitiuk, the SBU's former head of cybersecurity, for alleged illegal wiretapping and abuse of office in a case the SBU dismissed as "revenge" by anti-corruption agencies against its leadership. This tit-for-tat escalated further in October 2025, with SAPO head Oleksandr Klymenko publicly decrying SBU pressure tactics, including repeated interrogations and surveillance, which he linked to NABU probes into figures close to President Zelenskyy; the SBU rejected these claims, insisting its actions targeted only verifiable threats.[111][101][110] Broader institutional friction emerged on July 22, 2025, when Ukraine's parliament enacted legislation granting the executive branch—potentially including SBU oversight—expanded authority over NABU and SAPO leadership appointments and operations, prompting international criticism and a partial reversal after protests from EU partners and domestic reformers who viewed it as subordinating anti-corruption efforts to security apparatus control. The SBU has maintained that such measures are essential for countering hybrid threats, including alleged Russian infiltration of reformist institutions, whereas critics from anti-corruption circles argue the agency's expansive mandate enables selective enforcement to protect entrenched interests amid wartime opacity.[107][112][113]

Reforms, Oversight, and International Role

Oversight Mechanisms and Presidential Control

The head of the Security Service of Ukraine (SBU) is nominated by the President of Ukraine and appointed following approval by a majority vote in the Verkhovna Rada, Ukraine's parliament; the President retains unilateral authority to dismiss the head at any time. This dual process, outlined in the Law of Ukraine "On the Security Service of Ukraine," positions the presidency as the primary executive authority over the agency's leadership, with parliamentary consent serving as a formal check rather than a veto power. For instance, on July 28, 2022, President Volodymyr Zelenskyy appointed Vasyl Maliuk as acting head of the SBU, with the Verkhovna Rada's involvement limited to subsequent confirmation procedures amid wartime exigencies.[114][115] Parliamentary oversight is exercised primarily through the Verkhovna Rada's Committee on National Security, Defence and Intelligence, which reviews SBU activities, receives the agency's annual report from its head, and conducts inquiries into operations. The SBU is legally obligated to provide information and respond to committee requests, as stipulated in Ukraine's national security framework and intelligence laws, enabling scrutiny of counterintelligence, internal security, and resource allocation. However, the committee's effectiveness has been constrained by the imposition of martial law on February 24, 2022, which expanded executive powers and deferred certain parliamentary functions, including detailed audits during active conflict.[114][116] Complementing these structures, the President appoints a dedicated Commissioner for Control over SBU Activities to monitor compliance with legal mandates, investigate complaints, and report directly to the presidency; Roman Semenchenko has served in this role since his appointment on October 11, 2019. This mechanism reinforces presidential dominance, as the commissioner operates within the executive branch without independent prosecutorial or judicial authority. In practice, SBU accountability relies heavily on internal audits and judicial warrants for specific operations, but analysts note that the agency's alignment with presidential priorities—particularly in countering Russian influence since 2014—has prioritized operational autonomy over rigorous external checks, with the presidency holding ultimate directive power under Article 106 of Ukraine's Constitution.[117][114]

Reform Efforts and Challenges

Following the 2014 Revolution of Dignity, the Security Service of Ukraine (SBU) underwent initial restructuring to address corruption and ties to the prior regime, including mandatory asset declarations for officials starting in 2015. In 2018, President Petro Poroshenko announced a comprehensive reform plan to transfer investigative functions in areas like economic crimes and anti-corruption to other law enforcement bodies, aiming to refocus the SBU on counterintelligence and national security threats.[118] These efforts sought depoliticization, mandate restriction, enhanced transparency, and greater public oversight, with civil society organizations playing a role in advocacy.[119] Under President Volodymyr Zelenskyy, reform momentum continued with draft legislation in 2021 to eliminate the SBU's anti-corruption and organized crime departments, addressing inefficiencies and corruption loopholes inherited from its KGB-era structure.[120] However, implementation lagged, with no major overhaul by early 2020 despite high expectations.[121] On July 28, 2025, Zelenskyy signed a new SBU law increasing peacetime staffing from 27,000 to 37,000 personnel, authorizing use of weapons and equipment akin to the Armed Forces for defense tasks, and restructuring for improved operational effectiveness amid ongoing aggression.[20][122] Challenges have persisted due to bureaucratic resistance, entrenched secrecy enabling corruption schemes, and repeated failures of prior reform attempts amid political interference.[123][124][119] The 2022 full-scale Russian invasion shifted priorities toward wartime operations, deprioritizing structural changes and complicating vetting and lustration of personnel.[125] The 2025 law's expansion of SBU capacities coincided with parliamentary passage of Bill No. 12414, which curtailed independence of anti-corruption agencies like the National Anti-Corruption Bureau (NABU), sparking protests and criticism for potentially undermining rule-of-law gains by re-empowering security services over specialized investigators.[126][127] International partners, including the EU and NATO allies, have conditioned assistance on deeper reforms to prevent backsliding into politicized enforcement.[125]

International Cooperation and Assistance

The Security Service of Ukraine (SBU) maintains cooperative relationships with intelligence agencies from NATO member states and other Western partners, primarily focused on counterintelligence, counterterrorism, and countering Russian hybrid threats. These ties, which expanded significantly after the 2014 Russian annexation of Crimea, emphasize intelligence sharing, joint training, and operational support to bolster Ukraine's defensive capabilities against Moscow's influence operations.[53][128] The United States has been a primary partner, with the Central Intelligence Agency (CIA) providing extensive assistance to the SBU since 2014, including the reconstruction of Ukraine's intelligence infrastructure and training for counterespionage operations. This collaboration enabled the SBU to identify and neutralize Russian agents within Ukraine, with joint efforts reportedly rooting out hundreds of spies by 2024. The CIA also supported the establishment of 12 secret forward-operating bases near the Russian border, facilitating real-time intelligence exchanges and preparation for cross-border activities.[53][129][128] While U.S. officials credit this partnership with enhancing Ukraine's resilience against Russian penetration, the SBU has operated many missions independently to minimize risks of escalation or traceability to American sources.[130] The United Kingdom's Secret Intelligence Service (MI6) has engaged in trilateral cooperation with the CIA and SBU, particularly in areas like election interference prevention and sabotage operations targeting Russian assets. This framework, proposed as early as 2014, has included technical assistance and shared assessments of Russian activities in Europe. European Union structures, such as the EU Advisory Mission (EUAM) Ukraine established in 2014, offer strategic advice and capacity-building for SBU reforms, focusing on civilian security sector modernization, counterterrorism protocols, and protection of critical infrastructure.[131][132][129] NATO allies contribute through multilateral channels, including pre-invasion intelligence disclosures that warned of Russian military buildups and post-2022 training programs under initiatives like the NATO Security Assistance and Training for Ukraine (NSATU). These efforts, involving over 700 personnel from Allied nations as of July 2024, extend to SBU-relevant domains such as cyber defense coordination via the Tallinn Mechanism, launched in December 2023 to align Ukraine's capabilities with Western standards. Despite these advancements, challenges persist, including coordination gaps and the need for sustained funding amid Ukraine's resource constraints.[133][134][135]
