Royal Ransomware Actors Rebrand as “BlackSuit,” FBI and CISA Release Update to Advisory

Today, CISA—in partnership with the Federal Bureau of Investigation (FBI)—released an update to joint Cybersecurity Advisory #StopRansomware: Royal Ransomware, #StopRansomware: BlackSuit (Royal) Ransomware. The updated advisory provides network defenders with recent and historically observed tactics, techniques, and procedures (TTPs) and indicators of compromise (IOCs) associated with BlackSuit and legacy Royal activity. FBI investigations identified these TTPs and IOCs as recently as July 2024.

BlackSuit ransomware attacks have spread across numerous critical infrastructure sectors including, but not limited to, commercial facilities, healthcare and public health, government facilities, and critical manufacturing.

CISA encourages network defenders to review the updated advisory and apply the recommended mitigations. See #StopRansomware for additional guidance on ransomware protection, detection, and response. Visit CISA’s Cross-Sector Cybersecurity Performance Goals for more information on the CPGs, including additional recommended baseline protections.

CISA encourages software manufacturers to take ownership of improving the security outcomes of their customers by applying secure by design tactics. For more information on secure by design, see CISA’s Secure by Design webpage and joint guide Shifting the Balance of Cybersecurity Risk: Principles and Approaches for Secure by Design Software.
