Ubisoft, home of the "Asssassin's Creed" and "Far Cry" series, released a statement saying that user data including user names, email addresses and encrypted passwords were accessed illegally. Read the statement here on the Ubisoft official forums.

As a result, Ubisoft is now urging all users to change their passwords, even for services in the event where you used a password similar to, or the same as, the one you used to access Ubisoft services. To change your password, click here.

There is some good news, though: Ubisoft assured users that payment information including debit and credit card numbers were not subject to the attack. Personal information including phone numbers and addresses weren't accessed either, according to the company's statement.
