+# Post-Exploitation Challenge
+
+### Room Link: Task 5 in https://tryhackme.com/room/meterpreter
+
+- Meterpreter provides several important post-exploitation tools.
+- 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.

+
+- 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).

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