id Software's revealed that its ageing QuakeCon forums have been hacked.
Zoom"In recent days, a hacker carried out an unlawful intrusion of the old forums.quakecon.org site, compromising usernames and passwords," the firm said on the Quakecon website.
"While we have taken appropriate steps to protect the new forums from attack, we recommend anyone using their old credentials on another site to change their passwords immediately.
"We regret any inconvenience this may have caused, and suggest you migrate to the new forums - which will be live shortly - to discuss QuakeCon 2011," it added.
Research published last month found that the recent spate of hacking attacks on games companies and websites has dented consumer confidence in digital services.
This year's QuakeCon will take place from August 4-7 at the Hilton Anatole Hotel in Dallas, Texas.
