- DMM Bitcoin, a Japanese cryptocurrency exchange, was hacked, resulting in the theft of 4,503 Bitcoins, valued at around $320 million.
- The exchange plans to raise 50 billion yen ($321 million) to compensate affected users.
- The hack is one of the largest in cryptocurrency history, ranking as the seventh-largest crypto hack by Chainalysis.
- The stolen Bitcoins were quickly transferred through various wallets and mixed using Tornado Cash, a service that enhances transaction anonymity.

The Hack and Its Impact
On May 31, DMM Bitcoin reported that digital assets worth $320 million, equivalent to 4,503 BTC, were stolen due to an unauthorized outflow. This attack is now ranked as the seventh-largest crypto hack by Chainalysis. Hackers exploited vulnerabilities in the exchange’s system, leading to this substantial loss.
The stolen Bitcoins were quickly transferred through various wallets, with some of the funds being mixed using Tornado Cash. Tornado Cash is a well-known mixing service that enhances transaction anonymity by severing the link between input and output addresses, making it difficult for authorities to track the transactions.
Commitment to Compensation
In response to the hack, DMM Bitcoin has committed to raising fifty billion yen to acquire Bitcoin and fully compensate affected users. The exchange emphasized that these purchases will be conducted in a non-disruptive manner to avoid significantly impacting the Bitcoin market.
The platform has enlisted the help of cybersecurity experts and regulatory authorities to analyze the breach and implement measures to prevent future incidents. Japan’s Financial Services Agency has mandated DMM Bitcoin to provide a detailed account of the hack and outline its compensation strategies.
Regulatory and Security Measures
Japan’s Financial Services Agency has mandated DMM Bitcoin to provide a detailed account of the hack and outline its compensation strategies. Finance Minister Shunichi Suzuki has pledged to enhance the security of the nation’s exchange platforms to prevent similar events.
DMM Bitcoin continues to work with law enforcement and cybersecurity professionals to recover the stolen funds and apprehend the perpetrators. Observers will be keen to see how the exchange strengthens user protection following this major security breach.
Temporary Suspension of Operations
In the wake of the hack, DMM Bitcoin has temporarily halted the buying of orders for spot trading, the opening of leveraged trading positions, and the screening of new account openings. Additionally, the processing of crypto withdrawals has been suspended for the time being, although withdrawals in Japanese Yen are still being processed, albeit slower than usual.
Historical Context
This hack is the most substantial crypto-related exploit the industry has faced in some time. It surpasses any hack seen so far this year or in 2023. The incident is only overshadowed by the 2018 Coincheck hack, where over $550 million worth of XEM was stolen, marking the largest crypto heist in Japan’s history.
The crypto industry has been plagued by numerous hacks and exploits, with billions of dollars lost due to security vulnerabilities. While 2023 saw significant losses, it did not match the record-breaking hacks of 2022, where over $4 billion was stolen across various platforms.
