技术细节

Ryuk ransomware emerged August 2018, operated by WIZARD SPIDER (TrickBot operators). Targeted large organizations for high ransoms ($100K-$12.5M+ per victim). Distribution: delivered via TrickBot/BazarLoader infections (human-operated). Encryption: RSA-2048 + AES-256 (CBC mode), unique key per file. Stops 40+ Windows services (backup, antivirus, database) and kills >180 processes. Deletes volume shadow copies (vssadmin delete shadows /all /Quiet). Disables Windows recovery: bcdedit /set {default} recoveryenabled No. Network propagation: uses Wake-on-LAN to activate sleeping network hosts for encryption. Believed based on Hermes ransomware sold by a North Korean-linked actor on underground forums. Predecessor to Conti ransomware which emerged from WIZARD SPIDER's operations in 2020.
