Fallchill and Volgmer are new malware threats from cyber actors out of North Korea, according to DHS and the FBI. Read a cybersecurity expert's advice to net admins about these malware alerts.
The Department of Homeland Security (DHS) and the Federal Bureau of Investigation (FBI) on Tuesday, November 14, 2017 issued two joint technical alerts. Both alerts pertain to threats from North Korean cyber actors: The remote administration tool (RAT) known as Fallchill and the trojan malware Volgmer. The tools appear to target the financial, aerospace, and media industries and other critical infrastructure sectors in the US and globally.
The North Korean government has engaged in long-term campaigns to target civilian and government systems and networks in the US. US-CERT, which is part of the DHS National Cybersecurity Communications Integration Center (NCCIC), released in August 2017 an analysis of a piece of malware known as DeltaCharlie, which North Korea uses in launching distributed denial of service (DDoS) attacks on companies or other domains. Government agencies refer to cyber actors or specific exploits by code names, and have grouped this suspected North Korean activity under the name Hidden Cobra.
