Mega mail breach fears

Webmail passwords of millions of users are allegedly for sale.

Hundreds of millions of usernames and passwords - purportedly for Mail.ru, GMail, Yahoo Mail and Microsoft email accounts - are on sale through Russian cybercrime bazaars, according to security expert Alex Holden. Most of the stolen data refers to mail.ru accounts.

Holden has form for calling the Adobe and later Target breach but the latest leak remains unconfirmed.

Mail.ru's initial checks found “no live combinations of usernames and passwords which match existing emails”, Reuters (the news agency which reported the breach) reports. ®
