this. Everything touted as a good "hacker" llm is notoriously back. If I wanted to build malware I'd just look at poc's on github. There's also a plethora of youtube vids on blackhat conferences that show you a lot of stuff. I also wouldn't just trust an LLM to write me an exploit or walk me through it when even the billion dollar ones can't tell me how to do stuff in photoshop. They are useful for other things.
But man, want to be a good hacker? Read the docs. Seriously. Good hackers read the docs and live off the land.
Certs I've found to be pretty superficial for the most part. I've taken pentest+, PNPT and started the OSCP before I realized that I wasn't becoming a good hacker. I was generally just being walked through tools and being given VMs that already ran with vulnerabilities. I won't say that poking it to find what's wrong doesn't instill a type of thinking. I've just found them to be reliant on established tooling and known vulnerabilities.
