I wrote up a little analysis of the MySpace Quicktime worm, and also
have a copy of the source code which I cleaned up and heavily commented.



Source Code:


To really appreciate this worm, compare it to the source of Samy
(http://namb.la/popular/tech.html) or Yamanner
This worm subclasses native JavaScript objects, has good use of
functions, no wasted or unnecessary globals, pulls source from multiple
server, etc. On top of that the MySpace vuln to include the menu with
Phishing is only two weeks old, while the backdoored Quicktime movie
vector is a few months old. Just like attackers wait for MS patch
Tuesday to write malware, it seems people are actively reading web
security resources and using them to generate worms. It is also
interesting that more and more worms, from Space Flash to Yamanner, to
this, are being used to try and generate revenue instead of simply
