🚨 XaocMail, Phantom53, and Havoc: Anatomy of a Halloween Threat Cocktail | SOCRadar STRU IOC

SOCRadar Threat Research Team (STRU) recently identified a multi-stage campaign operated by a Russian-speaking threat actor wielding an AI-assisted toolkit. The adversary’s pipeline chains XaocMail (translated as ChaosMail), a phishing platform delivering ClickFix-style document sharing lures with Phantom53, a stealthy DNS-over-HTTPS (DoH) command-and-control (C2) framework used to drop PowerShell payloads and deploy the Havoc post-exploitation framework on-demand.
