About this groupFirst seen 2025-04-02

warlock

According to ransomware.live, The Warlock ransomware and operator(s) are believed to be attributed to Storm-2603, a China-based threat actor who is also known to have deployed LockBit ransomware. There's also a crossover between victims with Black Basta. Both are RaaS and have a long list of known and unknown affiliates. Having said that, this is possibly an affiliate (likely a cybergroup) of both of those groups. The Alliance & Association would technically be Encryptor Sharing, but this is realistically more of an "Old Affiliate" that created their own ransomware encryptor and operation.
