The passwords are not stored in plain text, they are stored as salted hashes. However, if you were using the same password as your Ubuntu Forums one on another service (such as email), you are strongly encouraged to change the password on the other service ASAP. Ubuntu One, Launchpad and other Ubuntu/Canonical services are NOT affected by the breach." Interestingly, members of a Libre Ubuntu derivative, Trisquel, place the blame of compromised security on Ubuntu's policy of using proprietary forum software. It appears the world's most popular GNU/Linux distribution, Ubuntu, serves as an example as to what happens when you use non-free software."
