The FBI and CISA have issued a warning regarding the Interlock ransomware, which is specifically targeting critical infrastructure sectors in the United States. This ransomware employs advanced techniques to disrupt operations and demands large ransoms, posing a significant threat to essential services. Organizations are urged to enhance their cybersecurity measures to mitigate the risks associated with such attacks.

The FBI reported that the Play ransomware group has breached approximately 900 organizations as of May 2025, a significant increase from previous counts. The gang employs advanced tactics, including recompiled malware and threats to leak stolen data, while urging affected organizations to enhance their security measures, including implementing multifactor authentication and maintaining updated systems.
