Uplay is Ubisoft's online service that allows access to its PC games, like Far Cry 3 and Assassin's Creed 3. If you play any of Ubisoft's games on PC, you may be one of the people who had their accounts hacked by Russian hackers. People who have reported their accounts hacked have said that their email addresses have been changed to ones pointing to a Russian website.

Ubisoft knows of the hacking and has posted on its Ubisoft Support Facebook page urging users to connect their Facebook (as a personal advice) to their Uplay accounts for added security. Just make sure your passwords aren't the same. Otherwise your Uplay getting hacked will be the least of your worries.
