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 ID
Session 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.
