Japanese crypto exchange DMM Bitcoin is warning that 4,502.9 Bitcoin, or approximately $308 million, has been stolen from one of its wallets today, making it the most significant cryptocurrency heist of 2024.
"At approximately 1:26 p.m. on Friday, May 31, 2024, we detected an unauthorized leak of Bitcoin from our wallet," DMM Bitcoin told customers.
DMM Bitcoin has not provided any information on how the theft occurred, but similar thefts were conducted in the past by gaining access to corporate systems or by exploiting flaws in smart contracts or websites.
The exchange apologized to customers, stating that all Bitcoin deposits will be fully guaranteed as they replenish the equivalent amount through the help of the group's companies.
Cryptocurrency intelligence firm Elliptic, who is tracking the stolen Bitcoin, says that the threat actors have already split the stolen Bitcoin into multiple new wallets.
BleepingComputer contacted DMM Bitcoin with questions about the breach but a reply was not immediately available.
