Russian internet and search company Yandex announced today that one of its system administrators had enabled unauthorized access to thousands of user mailboxes.
The investigation revealed that the employee's actions led to the compromise of almost 5,000 Yandex email inboxes.
BleepingComputer emailed Yandex for more details about the incident but received no reply at publishing time.
"Yandex's security team has already blocked unauthorized access to the compromised mailboxes," the company says, adding that the owners have already been alerted of the breach and that they need to change their account passwords.
As a result of the incident, Yandex will make changes to the administrative access procedure to increase the security of user data.
While this data breach deserves serious scrutiny, Yandex faced a graver threat in the past, when Western intelligence agencies compromised their systems with Regin malware.
