Joint Advisory Issued on Protecting Against Interlock Ransomware

CISA, FBI, HHS, and MS-ISAC issued a joint advisory regarding Interlock ransomware targeting North American and European organizations. The advisory details indicators of compromise, tactics, techniques, and procedures identified through recent FBI investigations. Organizations are urged to prevent initial access by using DNS filtering, web firewalls, and user training against social engineering. Mitigating known vulnerabilities through patching and updates is crucial for defense. Network segmentation helps restrict lateral movement of the ransomware within an organization. Implementing strong identity, credential, and access management policies along with multifactor authentication is also recommended. The advisory is part of the #StopRansomware campaign to provide guidance on various ransomware threats. It aims to inform network defenders about Interlock and other ransomware variants.
