Ubisoft's support center has posted a new notice asking Uplay users to update their passwords as soon as possible, owing to a recent website exploit. "We recently found that one of our Web sites was exploited to gain unauthorized access to some of our online systems," says the Uplay support team. "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." The support team adds that Ubisoft's security teams "are exploring all available means" to overhaul and strengthen Uplay's security features, in response to the exploit. Further details are not available at this time. "Unfortunately, no company or organization is completely immune to these kinds of criminal attacks." Uplay users can update their passwords here or learn more about the incident or file support tickets via Ubisoft's support center.
