SharpHook : Tool Tath Uses Various API Hooks In Order To Give Us The Desired Credentials

SharpHook is inspired by the SharpRDPThief project, It uses various API hooks in order to give us the desired credentials.

In the background it uses the EasyHook project, Once the desired process is up and running SharpHook will automatically inject its dependencies into the target process and then, It will send us the credentials through EasyHook’s IPC server.
