Maui Ransomware being use in HPH attacks

This joint CSA includes tactics, techniques, and procedures (TTPs) and indicators of compromise (IOCs) on Maui ransomware from FBI incident response actions and an industry study of a Maui sample. FBI, CISA, and Treasury encourage HPH Sector and other critical infrastructure organizations to adopt the advice in this CSA to prevent ransomware compromise. Maui ransomware victims should contact the FBI or CISA immediately.

In September 2021, the Treasury revised its guidance on ransomware sanctions risks and updated preemptive actions firms should take to reduce them. This update advises U.S. companies to implement and strengthen cybersecurity procedures and report ransomware assaults to authorities. When impacted parties take these proactive efforts,
