#StopRansomware Advisory: Interlock Ransomware Threats and Mitigation — tl;dr: The CISA, FBI, HHS, and MS-ISAC have issued a joint advisory on Interlock ransomware, first observed in September 2024, which targets businesses and critical infrastructure in North America and Europe. This ransomware employs a double extortion model, encrypting data after exfiltration to pressure victims into paying ransoms. Organizations are urged to implement DNS filtering, patch vulnerabilities, segment networks, and enforce multifactor authentication to mitigate risks. The advisory provides insights into the tactics used by Interlock actors, including drive-by downloads and social engineering techniques, emphasizing the need for robust endpoint detection and response capabilities.
