Incident Overview

South Korean exchange Upbit 342,000 ETH worth about $50 million was stolen. The exchange’s alleged theft occurred while assets were being transferred between hot and cold storage wallets, leading some to speculate that the incident may have been an internal job rather than an external breach. On January 14, 2025, the United States, Japan, and South Korea mentioned in a joint statement that the Upbit theft was attributed to DPRK.
