Today, CISA—in partnership with the Federal Bureau of Investigation (FBI)—released a joint Cybersecurity Advisory, North Korea State-Sponsored Cyber Group Conducts Global Espionage Campaign to Advance Regime’s Military and Nuclear Programs. The advisory was coauthored with the following organizations:

U.S. Cyber National Mission Force (CNMF);
U.S. Department of Defense Cyber Crime Center (DC3);
U.S. National Security Agency (NSA);
Republic of Korea’s National Intelligence Service (NIS);
Republic of Korea’s National Police Agency (NPA); and
United Kingdom’s National Cyber Security Centre (NCSC).

This advisory was crafted to highlight cyber espionage activity associated with the Democratic People’s Republic of Korea (DPRK)’s Reconnaissance General Bureau (RGB) 3rd Bureau based in Pyongyang and Sinuiju. The group primarily targets defense, aerospace, nuclear, and engineering entities to obtain sensitive and classified technical information and intellectual property to advance the regime’s military and nuclear programs and ambitions.

The authoring agencies believe the group and the cyber techniques remain an ongoing threat to various industry sectors worldwide, including but not limited to entities in their respective countries, as well as in Japan and India.

All critical infrastructure organizations are encouraged to review the advisory and implement the recommended mitigations. For more information on North Korean state-sponsored threat actor activity, see CISA’s North Korea Cyber Threat Overview and Advisories page.

Andariel actors fund their espionage activity through ransomware operations against U.S. healthcare entities.
