The Devman ransomware group emerged in 2025 as a financially motivated operation, initially functioning as an affiliate for larger ransomware gangs before evolving independently. Known for its 'Devman 2.0' version, the group engages in double-extortion tactics, exfiltrating sensitive data before encrypting it to pressure victims for ransom. They are highly active, claiming over 120 victims, and employ a sophisticated operational model focusing on stealth and rapid internal network compromise.
