The Gentlemen Ransomware Gang Gets a Taste of Its Own Medicine

The second most active ransomware operation globally just became a victim itself. The Gentlemen, a ransomware-as-a-service (RaaS) group responsible for over 400 publicly documented attacks in 2026, had its internal backend database compromised and leaked in early May—exposing chat logs, affiliate rosters, ransom negotiation transcripts, and operational details that defenders can now use against them.

Check Point Research published an analysis of the leak, which provides a rare inside look at how modern ransomware operations actually function behind their public-facing leak sites.

How The Gentlemen Got Hacked

The breach traces back to 4VPS, a bulletproof hosting provider that The Gentlemen used to run core infrastructure. When 4VPS itself was compromised, attackers gained access to The Gentlemen's backend systems.

The group's administrator acknowledged the incident on underground forums on May 4, 2026, confirming their database had been exposed. The data initially appeared for sale on the Breached forum for $10,000 in Bitcoin before eventually being dumped publicly.

This is the second time we've seen The Gentlemen's operational security fail. We previously covered how researchers gained access to a SystemBC C2 server operated by a Gentlemen affiliate, revealing over 1,570 compromised corporate networks that never made public victim lists. That incident showed the group's true scope; this one exposes how they actually operate.

What the Leak Reveals

The compromised data includes several categories of sensitive operational intelligence:

Leadership structure: The operation centers on approximately nine named operators organized around a single administrator using the handles "zeta88" and "hastalamuerte." This individual manages the platform, personally participates in attacks, and handles affiliate payouts. Before launching The Gentlemen, the admin worked with the Qilin ransomware group, learning the trade under an established operation.

Business model: The Gentlemen offers affiliates a 90/10 revenue split—significantly more generous than the industry-standard 80/20 arrangement. This aggressive pricing strategy helps attract experienced operators from rival programs.

Attack entry points: Chat logs confirm that nearly all successful breaches occur through unpatched internet-facing devices. VPNs and network appliances are primary targets, with specific exploitation of CVE-2024-55591 and CVE-2025-32433. When those fail, affiliates purchase credentials harvested by infostealer malware from underground markets.

AI-assisted development: The administrator built the entire RaaS admin panel in three days using AI coding assistants, specifically Chinese models DeepSeek and Qwen. This dramatically accelerates how quickly criminal operations can stand up infrastructure.

Supply Chain Attacks Inside a Criminal Operation

One of the more concerning revelations involves chain victimization. In April 2026, The Gentlemen breached a UK software consultancy and then weaponized the stolen access in a subsequent attack against one of the consultancy's Turkish clients. The consultancy's documentation, credentials, and infrastructure diagrams became tools for the next intrusion.

This mirrors legitimate supply chain attack patterns seen in nation-state operations, but applied to criminal ransomware. The consultancy was effectively used as an unwitting access broker.

The Intelligence Value of Criminal Leaks

When ransomware gangs get hacked, defenders win—at least temporarily. The exposed data helps security teams:

• Update detection rules based on known affiliate TTPs
• Identify compromised organizations that may not know they're already breached
• Map infrastructure that can be reported for takedown
• Understand negotiation tactics for potential future incidents

Similar leaks in the past, including the Conti ransomware playbooks that emerged in 2022, provided lasting defensive value because they revealed operational patterns that persist across criminal groups.

The Gentlemen remains active despite the breach, though affiliates may think twice about the group's operational security. When your hosting provider can expose your entire operation, the 90% revenue split starts looking less attractive.

For organizations concerned about ransomware defense, the leaked attack patterns reinforce familiar guidance: patch internet-facing devices promptly, monitor for credential theft indicators, and maintain offline backups. The Foxconn breach earlier this month showed what happens when even large enterprises fall victim to ransomware operations. Don't assume scale provides protection.
