On June 2, it has been reported that the exchange has encountered an apparent attack that could lead to customers’ personal data and e-mails being leaked, which suffered a $500 million hack in 2018 that was considered to be the biggest crypto theft in the history.
However, Coincheck said that the breach had “no impact on the customer’s assets” this time, as the exchange still had to halt its crypto remittance service in order to investigate the problem.
“Although there is no impact on your assets at this time, we will stop crypto remittance service again, considering the progress of the investigation by the domain registration service operator. Services such as depositing/withdrawing Japanese Yen and receiving/purchasing/selling crypto assets can be used as usual.”
The report also said that the breach took place on May 31 and June 1, as it purportedly affected around 200 customers, all of whom had sent in e-mail inquiries during that period.

The severity of the breach is apparently significant. Attackers may have stolen Coincheck clients’ e-mail addresses, as well as information like full name, date of birth, phone number, registration address, and selfie ID.
Thus, data breaches at crypto-related businesses are becoming increasingly frequent.
