From Day Zero to Zero Day: A Hands-On Guide to Vulnerability Research

can you please tell me what should be right approach what i should do that can help me.. Idk if i'm a good information resource (as i'm unemployed and have pretty bad problems with procastination and anhedonia), but here's a "path" (that can be done non linear/some steps learned with others at the same time) that i think can pretty much get you to a good level at RE/VR/Exploit Dev: Lern the fundamentals, depth as possible. So, really understand how memory works, C, networking (at least the basis), git, diff/patching, OS, etc. There's a LOT of resources on how to learn any of those things, some examples: Zhirkov book C Programming Language The Elements of Computing Systems Operating Systems: Three Easy Pieces MIT Algorithms Course Any Tanenbaum book For RE you can pretty much start with pwn.college, go for ost2 and do a lot of CTF's/crack.me. For VR there's not too much you can do besides reads tons of writeups about CVE's and start your own researching. For the second, the Eugene Lim book can help you. And that's it, tons of stuff to do more than just learn/read. With patience you will probably be fine.
