Hacker group LulzSec published the accounts of over 62,000 emails and passwords for free for download.Mikko H. Hypponen from F-secure believes that the emails and passwords were from a database kept by website Writerspace.com, according to the Hacker News.
Gizmodo took the database and has made a script for users to input their email address to check it against the release from LulzSec. Unless you were a member of Writerspace, you're probably not affected, but this is a good way to confirm.
