Using Vectra to Detect and Stop Maze Ransomware by Vectra AI Security Research team

This report describes the Maze ransomware family (aka ChaCha), its pioneering double-extortion model (encrypting data and exfiltrating it for blackmail), common attack progression (initial compromise, reconnaissance/privilege escalation, lateral movement, exfiltration, and ransomware detonation), observed tooling (Cobalt Strike, Mimikatz, PsExec, BloodHound), and how Vectra AI’s behavior-based detections identify precursor behaviors and active infections, illustrated by a post-incident case where reconnaissance and data exfiltration were detected prior to encryption.
