SharpHide is just a nice persistence trick to confuse DFIR investigation. Uses NtSetValueKey native API to create a hidden (null terminated) registry key. This works by adding a null byte in front of the UNICODE_STRING key valuename.
The tool uses the following registry path in which it creates the hidden run key: (HKCU if user, else HKLM)\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

Usage
To Create hidden registry (Run) key:
SharpHide.exe action=create keyvalue=”C:\Windows\Temp\Bla.exe”
To Create a hidden registry (Run) key with parameters:
SharpHide.exe action=create keyvalue=”C:\Windows\Temp\Bla.exe” arguments=”arg1 arg2″
Delete hidden registry (Run) key:
SharpHide.exe action=delete
This tool also works with Cobalt Strike’s execute-assembly.
