Valve, the owner and creator of Dota 2, claims that the stolen database contains only forum accounts and that no Steam accounts were compromised.
Some of the user names and passwords on the forum probably match the user names and passwords for their Steam accounts. So we would not be surprised to see a spike in Steam account hijacking.
1. If you are a Dota 2 forum user, change your password there. Remember to make it strong enough.2. Check to see if LeakedSource has information about your account. If so, you’ll probably want to delete it. [leakedsource[.]com/]
3. If you have used the same password anywhere else, change all of your passwords. And learn how to handle them properly — we have a blog post about that for you.
4. To further protect your Steam account, enable two-factor authentication using Steam Guard.
5. After you have completed those four critical steps, it’s a good idea to get educated about other threats in the world of computer games. We — wait for it — have a post about that as well.
