Threat Actor Profile
Lazarus Group (ATP38)
Country of Origin
Lazarus Group is linked to North Korea and is believed to operate under the Reconnaissance General Bureau, the primary intelligence agency of the Democratic People’s Republic of Korea (DPRK). The group’s activities align with state objectives, including financial gain for an economy burdened by international sanctions and furthering the regime’s political goals.
Members
The Lazarus Group is structured into specialized subgroups for various operations: Andariel focuses on financial theft and ransomware, Bluenoroff targets large-scale financial heists and cryptocurrency, and Kimsuky primarily conducts cyber espionage.
Leadership
The leadership of the Lazarus Group remains largely unidentified. However, it is reportedly governed by North Korea’s Reconnaissance General Bureau. Notably, Park Jin Hyok, a member of the Chosun Expo Joint Venture, was charged in 2018 by the U.S. Department of Justice for his involvement in Lazarus-associated operations.
