Who Runs the Ransomware Group ‘The Gentlemen?’

A cybercrime group known as The Gentlemen has emerged as the second most active ransomware gang , rapidly attracting a talented pool of hackers through an aggressive recruitment strategy that promises affiliates 90 percent of any ransom paid by victims. This post examines clues pointing to a real life identity for the administrator of The Gentlemen ransomware group. A graphic created and shared 2026. Experts at the security firm Check Point Software have been closely covering exploits of The Gentlemen, a so-called “ransomware-as-a-service” (RaaS) offering that pays affiliates handsomely to help spread the group’s malware. “A 90/10 affiliate revenue split — compared to the industry standard 80/20 — is accelerating the group’s growth ,” the researchers wrote in April. Check Point found The Gentlemen are the second most active ransomware group , claiming at least 332 published victims since the group’s inception in mid-2025 and more than 240 in 2026 alone. According to Check Point, the group targets Internet-facing devices (VPNs, firewalls) as their entry point, and once inside moves quickly to encrypt entire networks within hours. Check Point says the administrator and primary operator of the ransomware group uses the nickname Zeta88 on the Russian-language cybercrime forums, and that this individual was previously known under the moniker Hastalamuerte. Check Point noted that a breach of the group’s backend infrastructure made it clear that Hastalamuerte/Zeta88 is the person who assembles the locker and RaaS panel, manages payments, and is essentially the administrator of the entire program who receives 10 percent of all ransoms. The cyber intelligence firm Intel 471 shows that the user Hastalamuerte is a Russian and English speaking person who registered on almost a dozen cybercrime forums between 2019 and the present day, including Exploit, Breachforums, Ramp_V2, BHF, Raidforums, and Nulled. Intel 471 reveals that Hastalamuerte registered on Breachforums in January 2025 from an Internet address in Izhevsk, the capital city of Russia’s Udmurt Republic. Likewise, the user Zeta88 signed up at the English-language cybercrime forum Breached in August 2022 from a different Internet address in Izhevsk. Intel 471 finds Hastalamuerte registered on Raidforums in 2020 using the email address hastalamuerte1488@protonmail. com (1488 is a common combination of two numeric symbols associated with white supremacy). A lookup on this address at the open source intelligence service Epieos shows it is connected to an account at Apple and to a phone number ending in 04. Epieos says that Protonmail address is also linked to a GitHub account under the username SantaMuerte. That account is marked private, but a history of this user’s activity shows they are watching and developing a number of malware tools and exploits.
