So why did we specify credentials then? On Windows 10 you can't use SMB unauthenticated by default. And as far as I know there isn't a way to give msbuild credentials directly. So I fiddled around and find a little trick to cache some credentials for my SMB server on the host. As you see I use hacker/hacker for authentication. Very secure of course. On the target, trigger an authenticated
net use command. This should try to access the SMB share with the specified credentials, and therefore cache them locally on the target. From an opsec perspective this isn’t ideal, so if you have suggestions please reach out.
