Summary
Description
This Malware Analysis Report (MAR) is the result of analytic efforts between the Department of Homeland Security (DHS) and the Federal Bureau of Investigation (FBI). Working with U.S. Government partners, DHS and FBI identified Trojan malware variants used by the North Korean government. This malware variant is known as TYPEFRAME. The U.S. Government refers to malicious cyber activity by the North Korean government as HIDDEN COBRA. For more information on HIDDEN COBRA activity, visit https://www.us-cert.gov/hiddencobra.
DHS and FBI are distributing this MAR to enable network defense and reduce exposure to North Korean government malicious cyber activity.
This MAR includes malware descriptions related to HIDDEN COBRA, suggested response actions and recommended mitigation techniques. Users and administrators should flag activity associated with the malware, report the activity to the DHS National Cybersecurity and Communications Integration Center (NCCIC) or the FBI Cyber Watch (CyWatch), and give the activity the highest priority for enhanced mitigation.
This malware report contains analysis of 11 malware samples consisting of 32-bit and 64-bit Windows executable files and a malicious Microsoft Word document that contains Visual Basic for Applications (VBA) macros. These files have the capability to download and install malware, install proxy and Remote Access Trojans (RATs), connect to command and control (C2) servers to receive additional instructions, and modify the victim's firewall to allow incoming connections.
