If you've ever signed up for a Uplay account, your information could now be in the hands of criminals. Ubisoft's confirmed that a security breach at one of its sites, now closed, has granted hackers access to sensitive user data (i.e., usernames, emails and passwords). Critically, no actual financial information was leaked, owing to the fact that Ubisoft doesn't retain personal credit or debit card account numbers on its servers. Regardless, the Assassin's Creed developer is taking proactive measures, contacting account holders directly and strongly advising them to update any related passwords. You can find the full email just after the break.
