Everest is a Russian-speaking, financially motivated cybercrime and ransomware-extortion group active since late 2020. Also known as Everest Group, Everest Ransomware, Everest Team, and Everest Ransomware Gang, it has operated parallel revenue streams involving ransomware and double extortion, data-theft extortion, brokering initial access, and recruitment of corporate insiders. Everest has advertised stolen remote-access credentials and solicited insiders able to provide network access. Everest initially deployed ransomware but later emphasized theft of victim data and extortion without necessarily encrypting systems. It operates a leak site and has publicly claimed victims across North America, Europe, Asia, and Latin America. Confirmed activity includes theft of technical data from a shared supplier data-exchange environment after use of compromised supplier credentials. The group has targeted organizations in technology, manufacturing, telecommunications, financial services, and professional-services sectors. Everest has a documented code connection to BlackByte, but no confirmed operational relationship with LockBit has been established.
