We got hacked. It's under control, but the cocksucker tagged us during the WWDC keynote, when I was otherwise occupied. We have cleaned up, except we need to replace some vandalized HTML from backup and upgrade some software before the webserver can go back up. Email and other services are working.
For the record, it looks like he used a PHP exploit to execute a file which locally exploited the Linux 2.4.20 ptrace() hole. This means he had a root shell.
What you can do:
Again, everything is back up but the web server, which will come back hopefully tonight.
Stay tuned, True Believers.
