This Metasploit module exploit BITS behavior which tries to connect to the local Windows Remote Management server (WinRM) every times it starts. The module launches a fake WinRM server which listen on port 5985 and triggers BITS. When BITS starts, it tries to authenticate to the Rogue WinRM server, which allows to steal a SYSTEM token. This token is then used to launch a new process as SYSTEM user. In the case of this exploit, notepad.exe is launched as SYSTEM. Then, it writes shellcode in its previous memory space and trigger its execution. As this exploit uses reflective dll injection, it does not write any file on the disk. Vulnerable operating systems are Windows 10 and Windows servers where WinRM is not running. Lab experiments has shown that Windows 7 does not exhibit the vulnerable behavior.
