Kr00k was discovered by ESET Experimental Research and Detection Team, most prominently ESET security researcher Miloš Čermák.
It was named Kr00k by Robert Lipovský and Štefan Svorenčík. It was discovered when trying variations of the KRACK attack.
Initially found in chips made by Broadcom and Cypress, similar vulnerabilities have been found in other implementations, including those by Qualcomm and MediaTek.
The vulnerability is known to be patched in:
During their research, ESET confirmed over a dozen popular devices were vulnerable.
Cisco has found several of their devices to be vulnerable and are working on patches. They are tracking the issue with advisory id cisco-sa-20200226-wi-fi-info-disclosure.
