[SBI Crypto Suspected to Have Suffered a North Korean Hacker Attack, Losses of $21 Million] BlockBeats reports that on October 1, suspicious outflows of approximately $21 million were detected from wallet addresses associated with SBI Crypto, a subsidiary of Japanese financial giant SBI Group, on September 24, 2025. The stolen funds include BTC, ETH, LTC, DOGE, and BCH. These funds were subsequently transferred to five instant exchange platforms and then deposited into Tornado Cash for mixing. In a Telegram post, ZachXBT pointed out that multiple signs resemble previous hacking methods supported by the North Korean state, raising concerns that this incident may be yet another cryptocurrency theft linked to North Korea. As a mining pool operator under SBI Group, SBI Crypto's parent company is a publicly listed Japanese financial group with significant investments in both traditional finance and digital assets.
