The FBI and the Cybersecurity Infrastructure Security Agency (CISA) have released new information about North Korean malware in the form of six new Malware Analysis Reports (MARs). US agencies have released these MARs to provide organizations with detailed malware analysis information that has been acquired through manual reverse engineering of malware samples. At the same time, reports have also been released to help network defenders detect and reduce exposure to malicious activity by the North Korean government, which the US government calls HIDDEN COBRA. CISA recommends that all users and administrators carefully review the seven MARs in a blog post, saying, "Each MAR includes malware descriptions, suggested response actions, and recommended mitigation techniques." Users or administrators should report activity associated with the malware and report the activity to CISA or FBI Cyber Watch (CyWatch), and give the activity the highest priority for enhanced mitigation.
