The FBI and CISA recently published an update to the joint Cybersecurity Advisory “#StopRansomware: 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 variants (previously Royal).
FBI investigations identified these TTPs and IOCs as recently as July 2024. See WaterISAC’s coverage of the last two updates to the Joint Advisory.
