Who Runs the Ransomware Group ‘The Gentlemen?’

**Executive summary:** The Gentlemen is a rapidly expanding ransomware-as-a-service gang that has claimed at least 332 victims since mid-2025 and uses an aggressive 90/10 affiliate revenue split to recruit operators; Check Point reports the group targets internet-facing devices (VPNs, firewalls) and can encrypt networks within hours. OSINT from multiple providers links the administrator aliases Hastalamuerte/Zeta88 to online accounts, Telegram identifiers, and a phone number that pivot to records naming Alexander Andreevich Yapaev in Izhevsk, suggesting a likely real-world identity while outlining the group's operations and growth.
