Penetration tests

I've started studying pentesting in 2018, with the Ethical Hacking Fundamentals course by the teacher Marcos Flávio Araújo Assunção. Since then, I'm specializing on it through specialized courses and CTF platforms, such as Hack The Box. In Hack The Box, it's possible to simulate a Black Box attack, because it allows you to deploy a machine and gives you only its IP so that you can attack, and you need to identify the services being executed and how they can be explored.
