The Nightmare Course [1], so named because someone with that skillset (developing zero-days) is a nightmare for security, not because the course itself is a nightmare, and Roppers Academy [2] are both good for learning how to reverse engineer software and look for vulnerabilities.

The nightmare course explicitly talks about how to use Ghidra.

The first is certainly interesting, but it won't help you develop 0day. I would think of it like more of a collection of fun puzzles and esoterica. For example all the heap unliking/metadata attacks and House of X stuff is pretty antiquated. These will help you win ctfs but are certainly not a prerequisite or even all that relevant to contemporary vuln research. Most of the public research I see is probably at least a year behind the current meta (and I expect the public internet will only grow more quiet over time)

What resources would you recommend now? Even if they're a year behind the meta, it's a lot easier to start a year behind than 6+
