$21M in Bitcoin and Other Crypto Stolen From Japanese Miner SBI, Says Blockchain Sleuth
News Summary
Approximately $21 million in cryptocurrencies, including Bitcoin, Ethereum, Litecoin, Dogecoin, and Bitcoin Cash, was reportedly stolen from addresses linked to Japanese miner SBI Crypto, according to blockchain sleuth ZachXBT. The stolen funds were allegedly laundered via the crypto mixer Tornado Cash or moved to "instant exchanges." ZachXBT noted "several indicators share similarities to other known Democratic People's Republic of Korea attacks" and stated that SBI Crypto has not yet publicly disclosed the incident. This theft is the latest in a series of crypto breaches in 2025, following a $1.4 billion hack of Bybit and a nearly $50 million theft from Infini. The U.S. Treasury Department had placed Tornado Cash on its sanctions list in 2022 but removed it in 2025.
Background
SBI Crypto is a crypto mining pool owned by Japan's publicly-traded investment management company SBI Group. Its crypto arm, SBI VC Trade, agreed in 2024 to take control of DMM Bitcoin's customer assets and accounts following a $308 million hack. Tornado Cash is a coin mixing app designed to obscure Ethereum transactions. The U.S. Treasury Department added it to the Specially Designated Nationals list in 2022 but removed it in 2025. The U.S. Justice Department and other global law enforcement agencies have alleged that North Korean state-sponsored hacking group Lazarus Group used the app to launder stolen funds, linking them to the Bybit exploit and other incidents. The group typically employs decentralized exchanges and obfuscating apps to hide stolen assets.

What are the deeper implications of a North Korean-linked crypto theft for global cybersecurity cooperation and regulatory frameworks? - Given the potential link to North Korea's Lazarus Group, this incident underscores the severe challenge posed by state-sponsored actors continually exploiting cryptocurrencies for illicit financing. Even after the U.S. removed Tornado Cash from its sanctions list in 2025, the tool's alleged misuse highlights the limited effectiveness of merely sanctioning decentralized tools, necessitating more comprehensive international cooperation and technological solutions. - This event could prompt the U.S. and its allies, particularly Japan, to enhance cybersecurity intelligence sharing and joint response mechanisms against North Korea's growing digital financial capabilities. This could escalate geopolitical tensions and potentially lead to discussions for stricter international cryptocurrency regulations. With frequent crypto thefts in 2025, what risks does this pose to institutional investor confidence and the future institutionalization of the digital asset market? - The frequent occurrence of large-scale crypto thefts, including those targeting Bybit, Infini, and SBI Crypto, severely erodes institutional investor confidence in the security and stability of the digital asset market. These ongoing security breaches expose deficiencies in existing security protocols and infrastructure, likely leading institutions to adopt a more cautious approach when entering or expanding their investments in the crypto space. - This trend may compel regulators, including the U.S. Treasury and SEC under the Trump administration, to re-evaluate and potentially tighten compliance requirements and security standards for cryptocurrency exchanges, miners, and related services. While stricter regulation aims to enhance security, it could also increase operational costs and slow the pace of innovation in the short term, impacting the long-term growth trajectory and institutionalization of the digital asset market. What new challenges does Tornado Cash's return as a money laundering tool present to regulators after its removal from the U.S. sanctions list? - Tornado Cash's immediate use for laundering stolen funds after its removal from the sanctions list in 2025 presents significant challenges for global Anti-Money Laundering (AML) and Counter-Financing of Terrorism (CFT) efforts. This indicates that regulators face a dilemma in balancing privacy protection with combating financial crime, especially in the absence of clear accountability frameworks and technical solutions for decentralized protocols. - This escalating 'cat-and-mouse game' may push regulators to explore new technological means for tracking and analyzing on-chain activities, such as more advanced on-chain monitoring tools and AI-driven anomaly detection systems. Concurrently, it could spark international legal and ethical debates on how to define and enforce responsibility for decentralized protocol developers, profoundly impacting the future regulatory landscape of digital assets.
