Description

I have a PSAMSi server being run on a Kali VM with the Client being run on a VM. PSAmsi is properly finding the flags when using the -FindAmsiSignatures switch but is simply returning the original script with no modifications when the -GetMinimallyObfuscated flag is used.

Research direction

Reproduce the issue with the PSAmsi server on a Kali VM and the client on another VM. Run the working -FindAmsiSignatures path, then try -GetMinimallyObfuscated and compare the returned script with the original; done means the latter returns a modified payload as expected.
