Could you connect to this target without using a RDP file (do you use one ?), just by using: mstsc /v:1.2.3.4 ? and test again?

byehack commented 3 years ago

i tried with mstsc -v: 123.x.x.x and mstsc -v: 123.x.x.x /F -console. same results.

gentilkiwi commented 3 years ago

You don't have AutoLogon to true, because your AuthenticationLevel is 0 (not NLA at all, it's like typing your password on the Windows login screen) mstsc is not really aware of your creds, cause no NLA.

byehack commented 3 years ago

but i used saved creds to connect rdp.

gentilkiwi commented 3 years ago

If so, there are so many ways to get it :') But my prefered is by dpapi ;)

You can start by exploring with vault::cred But more fun by using files in: %localappdata%\Microsoft\Credentials with dpapi::cred : https://github.com/gentilkiwi/mimikatz/wiki/howto-~-credential-manager-saved-credentials

byehack commented 3 years ago

i know i can get it using dpapi.(which i tried and get it.) but i suprised why mstsc dumping doesn't working. btw it is because No NLA. i will try using NLA on to connect rdp.

byehack commented 3 years ago

it worked with NLA. I have another proposal that add MCSPort to main result list.

gentilkiwi commented 3 years ago

Yeah, I think about AutoLogon and AuthenticationLevel too now ;)
