Pentesting Methodology
Hacktricks logos designed by @ppiernacho.
0- Physical Attacks
Do you have physical access to the machine that you want to attack? You should read some tricks about physical attacks and others about escaping from GUI applications.
1 - Discovering hosts inside the network / Discovering Assets of the company
Depending if the test you are perform is an internal or external test you may be interested on finding hosts inside the company network (internal test) or finding assets of the company on the internet (external test).
{% hint style="info" %} Note that if you are performing an external test, once you manage to obtain access to the internal network of the company you should re-start this guide. {% endhint %}
2- Having Fun with the network (Internal)
This section only applies if you are performing an internal test.
Before attacking a host maybe you prefer to steal some credentials from the network or sniff some data to learn passively/actively(MitM) what can you find inside the network. You can read Pentesting Network.
3- Port Scan - Service discovery
The first thing to do when looking for vulnerabilities in a host is to know which services are running in which ports. Let's see the basic tools to scan ports of hosts.
4- Searching service version exploits
Once you know which services are running, and maybe their version, you have to search for known vulnerabilities. Maybe you get lucky and there is a exploit to give you a shell...
5- Pentesting Services
If there isn't any fancy exploit for any running service, you should look for common misconfigurations in each service running.
Inside this book you will find a guide to pentest the most common services (and others that aren't so common). Please, search in the left index the PENTESTING section (the services are ordered by their default ports).
I want to make a special mention of the Pentesting Web part (as it is the most extensive one).
Also, a small guide on how to find known vulnerabilities in software can be found here.
If your service is not inside the index, search in Google for other tutorials and let me know if you want me to add it. If you can't find anything in Google, perform your own blind pentesting, you could start by connecting to the service, fuzzing it and reading the responses (if any).
5.1 Automatic Tools
There are also several tools that can perform automatic vulnerabilities assessments. I would recommend you to try Legion, which is the tool that I have created and it's based on the notes about pentesting services that you can find in this book.
5.2 Brute-Forcing services
In some scenarios a Brute-Force could be useful to compromise a service. Find here a CheatSheet of different services brute forcing.

6- Phishing
If at this point you haven't found any interesting vulnerability you may need to try some phishing in order to get inside the network. You can read my phishing methodology here:
7- Getting Shell
Somehow you should have found some way to execute code in the victim. Then, a list of possible tools inside the system that you can use to get a reverse shell would be very useful.
Specially in Windows you could need some help to avoid antiviruses: Check this page.\
8- Inside
If you have troubles with the shell, you can find here a small compilation of the most useful commands for pentesters:
