A network of 4.5 million passwords for Mail.Ru mailboxes hit the network

Yesterday, more precisely, late in the evening of September 7, a warning was posted “1,000,000 passwords from Yandex mailboxes leaked to the network” , which for many was a surprise and caused a storm of emotions. It is strange that this did not happen earlier, since the news about the base appeared on the forums at least in the morning of the sixth. The company "Yandex" has already given its comments on this matter.

However, it seems that the troubles of users of mail systems did not end there - a database of email addresses with passwords from the mail.ru mail service hit the network. This database contains 4,664,478 records. The relevance of the database has not been verified, but, given the situation with Yandex mail accounts, this continuation of the story does not seem incredible.

Some sources have already laid out the database without passwords to check their own accounts for getting into this database. Since the situation with Yandex.Post was publicized only after almost two days and only after getting on Habr, I consider it necessary to notify users here about this potential threat.

Let me remind you that if the mail turns out to be in such a database, it makes sense to change the password to a new one just in case, as well as on all related services that recover passwords to this email address, as well as third-party services that used the same password.
