New SuperBlack Ransomware Strikes via Fortinet Authentication Bypass

The SuperBlack ransomware, a modified LockBit 3.0 variant, is deployed by the Mora_001 threat actor using a double extortion strategy to steal and encrypt sensitive data. They exploit Fortinet vulnerabilities (CVE-2025-24472 & CVE-2024-55591) for initial access, escalating privileges by creating super_admin accounts. Persistence is maintained through HA configuration manipulation, while VPN brute-force attacks enable lateral movement. With FortiGate devices at risk globally, organizations must urgently patch vulnerabilities and enhance security measures.
