Where did you search, and found it? I find nothing like a hash or a password.

I'm also stuck with the payload...

I use https://github.com/decoder-it/psgetsyste...getsys.ps1 script to inject process inside winlogon. However, I get error code: ERROR_INSUFFICIENT_BUFFER

122 (0x7A)

The data area passed to a system call is too small.

I see process is being created but exits immediately.

winlogon has no enough memory to start cmd.exe? It's super weird.

Find a credential file and use it to invoke a reverse shell as this user
