Ubisoft is recommending that users change their account information due to a recent hack that accessed a number of usernames, email addresses, and encrypted passwords.
According to the company, one of Ubisoft's web servers was exploited allowing intruders to grab protected data from the account database. Luckily, no payment information, phone numbers, or physical addresses were stolen in the hack. Additionally, Ubisoft's Uplay service and game server uptime were not affected.
"We recently found that one of our Web sites was exploited to gain unauthorized access to some of our online systems," Ubisoft wrote in a statement. "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 asks that as a precaution, you change your account password. You can do so by following this link. They further recommend that you update your information on any other website or service that you use a similar password for.
If you have questions, Ubisoft has opened an official forum thread to handle them.
Ubisoft added that they have restored the "integrity of any compromised systems," and are actively continuing to investigate how the hack happened. They are currently working with relevant authorities and both Ubisoft and external security experts to try and make sure it does not happen again.
"Unfortunately, no company or organization is completely immune to these kinds of criminal attacks," the company concluded.
This incident comes right on the heels of an incident involving Ubisoft's digital storefront. The online store was temporarily closed due to an exploit that allowed users to download games for free, including the then unreleased Far Cry 3: Blood Dragon..
