Looks like it might be a good time to update your password.
A new report has found that there has been a massive breach of security exposing “hundreds of millions” of stolen usernames and passwords belonging to these accounts.
Alex Holden, chief information security officer of Hold Security, has told Reuters that 272.3 million usernames and passwords have been stolen from users of Hotmail, Yahoo Mail, Google’s Gmail and Mail.ru, Russia’s largest email service.
The discovery came after researchers from Hold Security found a young Russian hacker – referred to as “The Collector” – bragging about the “heist” in an online forum.
The majority of data comes from Mail.ru. Fifteen percent of data is known to come from Yahoo Mail, 12 percent from Hotmail, and 9 percent from Gmail. Usernames and passwords for banking and retail are also among the stolen data.
It is one of the biggest stashes of stolen credentials to be uncovered since cyber attacks hit major US banks and retailers two years ago.
It is advised that all users of these email services change their passwords. All of the affected email services also offer a two-step verification process, which will ask for extra information if there is an attempt to log in from a new device.
