Right now I'm seeing the hacked site with the silhouette of the guy with two assault rifles walking toward the moon.
I'm also thinking the entire server might be hacked and not just the web site. Here is why. The hacker posted server stats on the page:
uname -a : SuxLife ! ~
Linux venus 2.6.28-16-server #57-Ubuntu SMP Wed Nov 11 10:34:04 UTC 2009 x86_64 GNU/Linux
Also, the <title> says "r00t3d By YazanRuleZ". rooted usually refers to hijacking the root account on a Linux machine. For those who don't know, root is the admin user, meaning the hacker might be in total control of the server and not just that one site. It's hard to tell looking from the outside, though.
I might be wrong, though. I'm not sure if atproxy.net is on the same server, but it seems to be working correctly.
