I would like to share a python script that lets you inject a shellcode in a binary to be executed through a TLS callback. If you don't know what I'm talking about I recommend you to read this post and this one.
Since I didn't find any script to do this automatically I made a first version to use it in my pentests; I’ve called it tlsInjector. This is not intended to be a serious tool (like the nice backdoor factory) but just an additional script to consider when you need to choose a persistence mechanism. Personally I don’t like leaving my evil binary in places where tools like Autoruns usually sniffs out.
