The Ubuntu forums are the latest to suffer a data breach, from a hacker, taking place last night. An estimated 1.82 million accounts have been affected and at the time of writing the site is still down for maintenance. According to the placeholder page currently on the Ubuntu site, only the forums were affected with Ubuntu One, Launchpad and other Ubuntu/Canonical services escaping the breach. The page also asks that although passwords were not stored in plain text, users who use the same password for multiple services such as email are "strongly encouraged to change the password on the other service ASAP." They also specifically admit that the hacker going by the name of @Sputn1k_ managed to grab "every user's local username, password, and email address from the Ubuntu Forums database." FYI, the Ubuntu forums uses vBulletin, which is a popular web-based forum software.
