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.
Supported Processes
| Process | API Call | Description | Progress |
|---|---|---|---|
| mstsc | CredUnPackAuthenticationBufferW | This will hook into mstsc and should give you Username, Password and the remote ip | DONE |
| runas | CreateProcessWithLogonW | This will hook into runas and should give you Username, Password and the domain name | DONE |
| powershell | CreateProcessWithLogonW | This will hook into powershell and should give you output for commands for when the user enters a different credentials. For example – Start-Process cmd -Credential X | DONE |
