Ubisoft is asking Uplay users to change their passwords as soon as possible after the service got hacked.
"We recently found that one of our Web sites was exploited to gain unauthorized access to some of our online systems," Uplay support team posted on Ubisoft’s Support Center. "We instantly took steps to close off this access, to begin a thorough investigation with relevant authorities, internal and external security experts, and to start restoring the integrity of any compromised systems."
"During this process, we learned that data were illegally accessed from our account database, including user names, email addresses and encrypted passwords. No personal payment information is stored with Ubisoft, meaning your debit/credit card information was safe from this intrusion."
Ubisoft vowed to overhaul and strengthen Uplay’s security in response to the exploit.
