Tokyo: Japanese crypto exchange DMM Bitcoin said it had lost bitcoin worth around $300 million in what it described as "an unauthorised leak" from its digital wallet.
"We are still investigating details of the damages," it said in a statement after detecting the "unauthorised leak" at around 13:26 (0426 GMT) Friday.
"We have already taken measures to prevent the unauthorised leak, but we have also implemented restrictions on the use of some services to ensure additional safety," the exchange said.
DMM Bitcoin did not give details on the "leak" but global cryptocurrency analysis firm Chainalysis said it was one of the biggest crypto hacks.
"Today's hack of Japanese exchange DMM Bitcoin for $305M worth of bitcoin is the biggest hack since Dec 2022 and the 7th largest crypto hack ever," Chainalysis said in post on social media platform X, adding it had labelled the funds as "stolen".
