GentleKiller targets more than 400 security processes across 48 products
ESET details the Gentlemen ransomware gang's in-house GentleKiller EDR-killer framework targeting over 400 security processes across 48 products, supplied to affiliates.
ESET analyzed the Gentlemen ransomware gang's in-house GentleKiller EDR-killer framework, confirmed through an internal data leak from May 2026. The framework has at least eight variants impersonating legitimate security products and abusing vulnerable or malicious kernel drivers, targeting more than 400 process names across 48 security products. Gentlemen emerged in late 2025, became one of the five most active ransomware gangs in Q1 2026, offers affiliates a 90% ransom share, and practices double extortion using Go-based and C-based ESXi encryptors. The suite also reuses outside tools including HexKiller, ThrottleBlood, and HavocKiller, unified by a shared evasion layer that mimics well-known security vendors.
