Post-Exploitation

Commands mentioned previously, such as getsystem and hashdump will provide important leverage and information for privilege escalation and lateral movement. Meterpreter is also a good base you can use to run post-exploitation modules available on the Metasploit framework. Finally, you can also use the load command to leverage additional tools such as Kiwi or even the whole Python language.

Loading Python

meterpreter > load python
Loading extension python...Success.
meterpreter > python_execute "print 'TryHackMe Rocks!'"
[+] Content written to stdout:
TryHackMe Rocks!

meterpreter >

The post-exploitation phase will have several goals; Meterpreter has functions that can assist all of them.

• Gathering further information about the target system.

• Looking for interesting files, user credentials, additional network interfaces, and generally interesting information on the target system.

• Privilege escalation.

• Lateral movement.

Once any additional tool is loaded using the load command, you will see new options on the help menu. The example below shows commands added for the Kiwi module (using the load kiwi command).

Loading Kiwi

meterpreter > load kiwi
Loading extension kiwi...

Success.

These will change according to the loaded menu, so running the help command after loading a module is always a good idea.The updated help menu
