A data breach of two popular gaming forums, Xbox and PlayStation has exposed the account details of 2.5 million users, potentially opening up their other online accounts to attack by hackers.
Both forums offered a way for gamers to share links to download free versions of games.
Even if users didn't have financial details stored on the sites, the information could be used to break into other sites, if users have the same password for different accounts.
If you use one of these forum, change your password of other sites, if they are same as fast as possible.
