Germany Doxes "UNKN," Head of RU Ransomware Gangs REvil, GandCrab (krebsonsecurity.com)

German authorities have identified the elusive hacker known as “UNKN” as Daniil Maksimovich Shchukin, whom the BKA says led Russia-linked ransomware operations GandCrab and REvil from 2019 to 2021. The BKA alleges Shchukin, along with Anatoly Sergeevitsch Kravchuk, carried out dozens of attacks that produced nearly €2 million in extortion and more than €35 million in total economic damage, and it links earlier U.S. seizure efforts tied to REvil proceeds to Shchukin. The article describes how GandCrab and REvil used double extortion and how REvil’s later compromise of Kaseya contributed to its decline.
