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

The outflow amount was approximately 482 億円 equivalent (converted at the rate at the time the outflow occurred). The quantity of BTC that flowed out was approximately 4,502.9 BTC (based on multiple reports — the company’s primary press release is currently inaccessible). To contain the situation, the company announced fundraising on the scale of 550 億円 and carried out a market buy-back of BTC, but ultimately gave up on continuing the business (for details 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); as sister cases, Bybit Lazarus Hack Detailed Analysis and Coincheck Nem Hack Detailed Analysis are comparable).

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.
