This repository demonstrates a technique for creating DLL-Wrappers using a manual implementation of each exported function from the original DLL module. The built-in Windows amsi.dll was used as an example here. This technique can be used to perform some more stealthy DLL-Hijacking tactics, or for conveniently manipulating module parameters (function input and output) to get a better idea of what is going on.
