psexec

Impacket's psexec is a script within the Impacket suite that emulates the functionality of Microsoft's PsExec tool. PsExec is a part of the Sysinternals Suite and allows execution of processes remotely by creating a service on the remote system. Impacket's psexec provides similar functionality, enabling users to execute commands or launch an interactive shell on remote Windows machines.

It allows for the execution of commands on a remote Windows machine. Users can spawn an interactive shell on the remote system, which is extremely useful for administration tasks or penetration testing scenarios. The script supports NTLM authentication, making it possible to authenticate against remote systems using either a password or an NTLM hash (pass-the-hash). psexec is widely used for legitimate network administration tasks and in penetration testing for gaining remote access to systems.

An example:

python psexec.py <DOMAIN>/<USERNAME>:<PASSWORD>@<TARGET_IP> cmd.exe

• <TARGET_IP> is the IP address of the target Windows machine.
• cmd.exe is the command to be executed on the remote system. This could be replaced with any command or even a path to an executable script.

If you wish to spawn an interactive shell, you might use the script without specifying a command:

python psexec.py <DOMAIN>/<USERNAME>:<PASSWORD>@<TARGET_IP>
