What is RunAsUser? ----------------------------------------------------------RunAsUser is able to run a command as another user. You need the local administrator privileges and the user must have a running process on the system.
How does it work? ----------------------------------------------------------RunAsUser uses dll injection techniques to gain SYSTEM privileges. With SYSTEM privileges the dll is able to open the target process, duplicate the access token and run a program with the user privileges.
What I can do with RunAsUser? ----------------------------------------------------------RunAsUser can be used in a lot of situations, the most interesting usage is the privilege escalation that can be done on a Microsoft domain. If the user has local administrator rights and a domain admin is logged on the system you can get domain administrator privileges.
Command line arguments ---------------------------------------------------------- -p <pid> Pid of the target process -c <command> Command to be executed with user privileges -s <session ID> Target session IDSession where the new process is spawned. To get your current session id run taskmgr.exe, go to "View" -> "Select columns" and select "Session ID" and search one of your current processes.
-l <lsass pid> (optional)RunAsUser looks for the lsass.exe process. If this process fails, try using this option specifying the lsass pid.
