This is the Rootkit source code which was once delivered together with the SkypeTrojan. These days it was quite useful but now after some years have passed there is no reason to maintain it any longer. The AV companies did a good job, detect it easily and I’m not motivated to implement other methods. There are other things to explore which pose a bigger challenge than rootkits. But mainly there are other people around whom are more passionate and dedicated to this field :)

This Rootkit only runs on Microsoft Windows. To be more precise on Windows XP. If you want to compile it you first have to install the DDK (Driver Development Kit). Well at least in 2006 the DDK was required to compile a kernel module. Since then I’ve never worked with kernel modules again and maybe Microsoft delivers the necessary libs and header files even with the VS Express editions.

You find the source code here.
