How can vshadow.exe be abused for both persistence and evasion in a penetration test?
`vshadow.exe` from the Windows SDK carries a Microsoft signature, allowing it to bypass some application whitelisting controls. It can be used to execute arbitrary commands (e.g., `vshadow -nw -exec=notepad.exe c:`) within a snapshot context, leaving VSSVC.exe running as a background process. This can be leveraged for persistence by setting it as a startup item, and it does not appear in Autoruns' default startup list, making it harder to detect. The full exploitation approach is detailed in Domain Penetration - Obtaining the NTDS.dit File from Domain Controller Servers and related resources.
