The website is down pending a fix to PHP's 0day expl0itz.
No this site didn't get hacked. This is a temporary workaround until PHP is fixed.
In the meantime, check out this shellcode from the draichess archives, shellcode2.tgz...
char shellcode[] = "\xeb\x36\x5e\x31\xdb\x31\xc0\xb3\xff\x89\xf1" "\x41\x8a\x1\x39\xd8\x75\xf9\x89\xcf\x31\xdb\x88\x1f\x47\x89\xfc" "\x83\xc4\xc\x31\xc0\x50\x50\x56\x31\xc0\x83\xc0\xb\x89\xf3\x89" "\xf9\x89\xfa\x83\xc2\x8\xcd\x80\x31\xc0\x40\xcd\x80\xe8\xc5\xff" "\xff\xff/bin/sh\xff";
See if you can reverse engineer the shellcode without using any tools other than objdump.

I just migrated to wordpress as well... what a shame.
