The official Steam forums have been taken down by Valve after they were hacked late last night. Users who attempted to visit the site before they were taken down were being redirected to fkn0wned.com, a site offering gaming information, along with "warez, porn, hacking/security" and more.

However, despite the site's security/hacking focus, the owners of fk0wned.com, together with the site's subscribers, have denied any knowledge of the attack. While they're back online now, the fkn0wned.com forums went down for several hours, with the following message posted for everyone to see:
"Fkn0wned Forum is currently unavailable In lights of someone crediting us for the recent breaches of steam forums, the board is offline. Fkn0wned is not responsible."
This isn't the only hack referencing fkn0wned either. Twitter search results reveal the name appearing repeatedly in posts from what appear to be hacked or spamming accounts that include links to what may be malicious content.
Valve hasn't recommended that users change details such as passwords - but video game blog Kotaku recommends that if you use the same password for the Steam forums as you do for your Steam account, it might not be a bad idea to change it.
Valve has as yet given no indication that users' details may have been stolen.
