Hackers scoop $21 million from Japanese crypto mining pool SBI: ZachXBT - FXStreet

On-chain researcher ZachXBT reported a $21 million cryptocurrency hack targeting Japanese mining pool SBI Crypto, with funds transferred through Tornado Cash mixing service.

The attack involved the theft of Bitcoin, Ethereum, Litecoin, Dogecoin, and Bitcoin Cash from SBI Crypto wallets. Investigators identified patterns suggesting North Korean hacker groups were responsible for the breach. The stolen cryptocurrency was subsequently moved through five instant exchanges before being deposited into Tornado Cash, a cryptocurrency mixing service often used to obscure transaction trails.

• SBI Crypto has not yet officially confirmed the $21 million hack involving multiple cryptocurrencies
• Blockchain patterns indicate potential North Korean involvement, consistent with previous crypto exchange attacks
• Stolen funds were laundered through Tornado Cash, highlighting ongoing regulatory concerns about mixing services
• The incident adds to a series of major cryptocurrency exchange breaches in 2025, including the notable Bybit hack
