272.3 million accounts have had their privacy details hacked with usernames and passwords for email accounts on the Hotmail, Yahoo and Gmail servers being compromised, according to a report by Reuters.

The company that suffered the biggest security breach was Russia's most popular email service, Mail.ru, but millions of accounts from Gmail, Yahoo and Hotmail were also compromised. 40 million Yahoo Mail accounts were breached while 33 million Microsoft Hotmail users were targeted. Gmail accounts registered for 24 million of the theft.
