Crypto exchange Coincheck says it suffered a data breach, which may have exposed some users' personal information

Japanese cryptocurrency exchange Coincheck announced on Tuesday that it suffered a data breach, which may have leaked users’ emails and personal information.

The information includes name, registered address, birth date, phone number and selfie ID, said Coincheck. The breach affected around 200 customers who made email inquiries from May 31 to June 1, the exchange added.

Giving details of the breach, Coincheck said a third party unauthorizedly accessed its domain registration service and “fraudulently” accessed customer emails. The domain registration information has since been amended and there is “no impact on customers’ assets at this time,” said Coincheck.

As a result of the breach, the exchange has suspended its crypto remittance service, while other services such as trading, deposits and withdrawals remain active.

Last month, crypto lender BlockFi also suffered a similar data breach, which affected some of its retail clients. The breach lasted for "about an hour" and did not impact customer funds, BlockFi said at the time.

As of Coincheck, the exchange has previously suffered the biggest hack in crypto's history. In January 2018, Coincheck lost nearly $500 million in digital tokens. Japan-based online brokerage firm Monex Group later acquired Coincheck for $33.5 million, and the exchange is now a licensed entity.
