Pay2Key's Linux ransomware variant is analyzed in depth, showing a root-privileged, configuration-driven encryptor that enumerates mounts, disables defenses (stops services, kills processes, disables SELinux/AppArmor), persists via cron, and encrypts files using ChaCha20 with full or sampled modes; the report notes per-file key obfuscation, lack of observed C2 or exfiltration, and defensive recommendations for Linux environments.
