Sometimes, when we shine a light on a particular piece of malware, we find some interesting things that would otherwise go unnoticed. One such piece of malware is the trojan sometimes called "Troj/SpamThru", among other names.

Pretty interesting writeup of a modern trojan. A little disturbing in the sophistication of the software. I was especially impressed by the software downloading and patching a pirated copy of commercial anti-viral software, to remove competition on the host.
