I don't personally have anything to do with spreading or operating RATs and Botnets, however this is just really cool.
The fact that you have thought of a way to utilize the web servers you have taken over to further spread your virus is spectacular, great creativity. I would suggest you try to put the download link in a spot near the end of some process. Like near the very end of a checkout. I would assume that the web developer would never just run through a whole checkout sequence once it is developed unless a bug is reported, that way they should never see the change to their website.
