Comic Cmoa has confirmed that the personal data of up to 4.2 million users was lost during a recent server breach.

In a statement from October 21, Japan's biggest manga site revealed that system log files including email addresses, nicknames, date of birth, and gender information were lost during the attack. That being said, it was quick to reassure users that passwords have not been compromised, with only 319 having such information leaked in an encrypted format as part of an internal database.

As of the time of writing, the website is still inaccessible. No timeline has been given on restoration, but work is proceeding on reactivating certain features once safety has been assured. In the meantime, the site urged users to beware phishing emails that might arrive based on the leaked data.
