Unauthorized outflow incident (2024-05-31) details:

The National Police Agency materials state that 4,502.9 BTC was lost, valued at approximately ¥48.2 billion at the time. The company announced a fundraising plan on the scale of ¥55 billion and a policy to buy back the equivalent BTC; it later terminated service and transferred customers to SBI VC Trade (see DMM Bitcoin outflow incident detailed analysis（2024-05）— 4,502.9 BTC attributed to Lazarus and Japan Domestic VASP Crypto Asset Breach History (2014-2026)).

Japan’s National Police Agency, the FSA, and the US FBI published, dated 2024-12-24, an identification of this case as an attack by “Trader Traitor (North Korea’s Lazarus Group)” and issued an advisory (recorded in the “Publication of ‘令和6年12月24日 Regarding cyber-attacks by the North Korea-backed cyber-attack group Trader Traitor (advisory)’” on the FSA page).

This case is one of the largest-scale unauthorized outflow incidents in the history of Japan’s crypto-asset industry.
