AlienVault OTX Malware

The Gentlemen is a ransomware-as-a-service (RaaS) group that emerged in mid-2025, targeting Windows, Linux, NAS, and BSD systems. It uses a double-extortion model by encrypting files and exfiltrating data. The ransomware is written in Go and employs ChaCha20 encryption with multiple speed modes. It terminates security processes using vulnerable drivers and spreads laterally via PsExec. A May 2026 breach exposed internal communications and affiliate information. The group primarily targets organizations in the United States and Europe across manufacturing, technology, healthcare, professional services, and retail sectors.
