Credsleaker allows an attacker to craft a highly convincing credentials prompt using Windows Security, validate it against the DC and in turn leak it via an HTTP request.
This script used to display a powershell credentials box asked the user for credentials. However, That was highly noticeable. Now it's time to utilize Windows Security popup!

The box cannot be closed (only by killing the process) and will keep on checking the credentials against the DC. If credentials fail at the DC, then they are checked against local SAM so that local accounts are leaked even if the machine is a domain member. When validated, it will close and process via chosen method.

Start a web server and upload cl_reader.php, config.php, config.cl to desired path
Fill out parameter defaults in CredsLeaker.ps1
Edit Pipeline parameters in run.bat to desired scenerio
Execute run.bat file.
To Dviros for a great script that I have learned a ton from! To all my friends that helped to craft this script (specially @deanf)
