Ubisoft today revealed that a hack of its systems exposed user names, email addresses, and encrypted passwords, but not financial data.

The attackers exploited one of Ubisoft's websites "to gain unauthorized access to some of our online systems," the company said in a statement. Ubisoft shut down the hackers' access, but discovered that they had infiltrated the company's account database.

"It's important to note that no personal payment information is stored with Ubisoft, so fortunately all credit/debit card information was safe from this intrusion," according to Ubisoft.

Ubisoft is recommending that all account holders change their passwords on ubi.com, as well as on other websites where they might have used the same password.
