I was thinking just about the same thing.
Why don't hackers call their projects "8d 7d 6c 05" or "33 02 ba 9c" in source code constants?
Why would they even include any non-essential things in the code at all?
Remember nimda virus ? (thats admin backwards)
NIMDA was a polymorphic plague of a virus that hit out network right after 9/11/2001.
It would write itself all over every file on the disk drive until the drive was full and everything came to a screeching halt. It exploited the NT web service that was active by group policy default on client boxes with NT and or Win 2000. Anyway, our software engineers looked inside the Nimda.dll and there was some jihad "Death to America, Death to Israel" crap commented right into the file!!
I'm sure that was the NSA's earlier work, as they took over most domestic networks just to be on the safe side....
