Jade Sleet is a North Korean government-linked threat actor tracked under Microsoft’s “Sleet” naming convention for DPRK cyber operations. It has been identified as one of several North Korean actors involved in large-scale cryptocurrency theft, alongside Sapphire Sleet and Citrine Sleet. North Korean Sleet actors are associated with financially motivated operations that generate revenue for the North Korean state, including programs tied to strategic weapons development. In the same broader DPRK operational ecosystem, North Korean actors have also conducted intelligence collection against South Korea, the United States, and Japan, and have targeted sectors such as education, cryptocurrency services, venture capital, and other financial organizations. High-confidence reporting in this context specifically ties Jade Sleet to cryptocurrency theft, but does not provide further actor-specific detail on its tooling, intrusion chain, or distinct victimology beyond its role in DPRK crypto-heist activity.
