#ProcessHider
This tools is allowed to use only for penetration testing and other white-hat activities. Illegal use is absoloutly frobidden!
ProcessHider is a post-exploitation tool designed to hide processes from monitoring tools such as Task Manager and Process Explorer, thus preventing the admins from discovering payload's processes. The tool works on both 32 and 64 bit versions, by self detecting the OS version and using the right version of the tool.
ProcessHider is available as a EXE file or as a Powershell script.

To build the project, use "build-me.bat" that's in the root directory. There are two versions of the complete script: EXE and Powershell.
To use the EXE, call the main file, ProcessHider, which is under MainFile\, from cmd, using the following options:
To use the Powershell, use Powershell\Output\fullScript.ps1, with the same arguments as the exe.
Example usage:
`ProcessHider -i 5454,3672 -n "chrome.exe,notepad.exe" -x "cmd.exe"`Note: you need to use at least one of -i or -n. The hider will make sure to hide itself as well.
The project uses the following libraries and projects:

There's no dependency on neither those libraries nor VC++ runtime, as they're all linked statically
First, the hider checks whether the OS is 32 bit or 64 bit, and chooses the right version to use. Then, it launches a daemon, which looks for one of the frobidden monitoring tools. When it finds one - it uses DLL injection to launch the payload - which hooks the call to NtQuerySystemInformation - the method the OS tools use to enumerate active processes, and deletes each of the processes specified (and the daemon) from the results.
Contributions are most welcome. Make sure that when working on the powershell scripts, don't work on the "fullScript" but rather on the "daemon-integration" and "Invoke-ReflectivePEInjectionLite", as the building script uses these files as sources to the fullScript/
