An elusive hacker who went by the handle "UNKN" and ran the early Russian ransomware groups GandCrab and REvil now has a name and a face. Authorities in Germany say 31-year-old Russian Daniil Maksimovich Shchukin headed both cybercrime gangs and helped carry out at least 130 acts of computer sabotage and extortion against victims across the country between 2019 and 2021.

Russian authorities have arrested six men accused of operating some of the most active online bazaars for selling stolen payment card data. The crackdown -- the second closure of major card fraud shops by Russian authorities in as many weeks -- comes closely behind Russia's arrest of 14 alleged affiliates of the REvil ransomware gang, and has many in the cybercrime underground asking who might be next.
