In what is likely one of the largest hacks of a digital-asset platform, the Japanese crypto exchange DMM Bitcoin said it detected “an unauthorized leak” of around $301 million from its digital wallet.
The exchange is still investigating the outflow, equal to 4,503 Bitcoin, the company said on its website. It’s restricted a slew of services, including cryptocurrency withdrawals. In a tweet, blockchain researcher Chainalysis called the incident a “hack,” and labeled the funds as stolen.
