Azazel – Userland Anti-debugging & Anti-detection Rootkit

Azazel is a userland rootkit written in C based off of the original LD_PRELOAD technique from Jynx rootkit. It is more robust and has additional features, and focuses heavily around anti-debugging and anti-detection. Features include log cleaning, pcap subversion, and more.

As with anything of this nature, it’s recommended you check the source-code/run it in a safe environment etc. But if I have to emphasise stuff like that, this is probably the wrong site for you.
