the reverse engineering track has broken my brain (in a good way)

I used to just use tools. Now I can't stop opening them up to see how they work.
Rebuilt 3 small tools so far just for fun. None of them are useful, all of them taught me more than any course I've paid for. CyberChef one was the gateway drug.
the cyberchef lesson got me too. 'how does this even work' is a dangerous question
