North Korean Malicious Cyber Activity

On May 12, 2020, the Cybersecurity and Infrastructure Security Agency (CISA), the Federal Bureau of Investigation (FBI), and the Department of Defense (DoD) released three Malware Analysis Reports (MARs) on malware variants used by the North Korean government.

The information contained in the alerts and MARs listed above is the result of analytic efforts between the U.S. Department of Homeland Security, the U.S. Department of Defense, and the Federal Bureau of Investigation to provide technical details on the tools and infrastructure used by cyber actors of the North Korean government. Each MAR includes malware descriptions, suggested response actions, and recommended mitigation techniques. Users or administrators should flag activity associated with the malware and report the activity to the Cybersecurity and Infrastructure Security Agency (CISA) or the FBI Cyber Watch (CyWatch), and give the activity the highest priority for enhanced mitigation. The U.S. Government refers to the malicious cyber activity by the North Korean government as HIDDEN COBRA.
