Black Suit

BlackSuit first appeared in May 2023 and is a confirmed rebrand or direct evolution of Royal Ransomware. It operates as a Ransomware-as-a-Service (RaaS), employing a double-extortion model—encrypting files and stealing sensitive data for leak threats. BlackSuit targets Windows and Linux systems, including VMware ESXi environments, using the .blacksuit extension for encrypted files. Technical analysis shows strong code overlaps (≈98%) with Royal, itself believed to be run by former Conti affiliates. Victims span healthcare, critical manufacturing, education, and government sectors, with notable incidents affecting public health systems in the U.S. Initial access vectors include phishing, exploitation of public-facing applications (e.g., Citrix and Fortinet vulnerabilities), and compromised credentials purchased from initial access brokers. Ransom notes direct victims to Tor-based negotiation portals.
