Google tells Iranian users to check if their Gmail accounts have been hacked

Filed Under: Data loss, Google, Privacy

Iranian flagGoogle is advising *all* its users in Iran to change their Gmail passwords, and check that their Google accounts have not been compromised.

In a blog post, Google said that it was directly contacting users in Iran who may have been hit by a man-in-the-middle attack.

As you've no doubt been reading on Naked Security, the threat emerged after disgraced Dutch SSL certificate authority DigiNotar was compromised.

As Google, correctly points out - it's not just a question of changing passwords. Even if hackers who broke into your Gmail account no longer know your password, there are still things they could have done *while* they had access to your email which will allow them to continue to monitor your communications.

For instance, it's possible for someone to have tampered with your Gmail account to silently forward all messages that you receive to another account.

Similarly, it's a good dea to check that no-one has been unexpectedly authorised to read and send email from your account.

Although ensuring that their Gmail has not been compromised will probably be the most obvious concern for many users, it's worth bearing in mind that other Google apps - such as Google Docs - could be at risk if you suffered from the man-in-the-middle attack.

Take Google's advice seriously and take steps to ensure that your account isn't compromised.
