The Gentlemen Ransomware Gang Industrialized EDR Evasion Into a Service Economy
The Gentlemen ransomware-as-a-service operation emerged in late 2025 and rapidly ascended to become a top-five ransomware gang by Q1 2026 through their innovative EDR killer framework. The crew developed an industrialized approach to endpoint detection and response evasion, creating eight or more variants of their GentleKiller tool that targets over 400 security processes across 48 different security products. By offering affiliates a generous 90% revenue share compared to the industry standard of 80%, Gentlemen scaled their operation through volume rather than per-incident margins, transforming EDR evasion from a technical skill barrier into a commodity service available to low-skill threat actors. This incident represents the maturation of the bring-your-own-vulnerable-driver (BYOVD) attack technique from isolated tactics into a full-scale economy with pricing tiers, product roadmaps, and customer support models, fundamentally changing the threat landscape defenders face.
