Overview

BravoX is an emerging Ransomware-as-a-Service (RaaS) operation that came to public attention on January 23, 2026. The group operates a selective affiliate model requiring targets with $5M+ annual revenue and excludes CIS countries. They employ double extortion tactics with data exfiltration via Rclone, VMDK encryption, and maintain a modern Vue.js-based data leak site with automated negotiation features. The group demonstrates operational creativity in persistence and defense evasion, particularly through BYOVD techniques using the wsftprm.sys driver (Killer.exe) to disable EDR solutions including Microsoft Defender and Sophos.
