I've been a noob to the cyber security industry since 2018 (going to be starting university this year to receive a BSc in Cyber Security and Networks and have worked 4 months as a Junior Penetration Tester in addition to self study) and I'm looking for study material to continue with after I've done a little more here on HTB.
I've completed CrackMe! in the RE section and Ropme in the pwn section of the site already for which I used python pwntools; after completing a challenge from web, taking a look into the mobile challenge and rooting a couple of boxes I'm really wanting to explore malware development and exploit development in detail.
I want to get to a point where I can find a vulnerability in a service manually and independently develop a working exploit to gain root (I'm aware it's not as simple as I've worded it!)
Anything would be helpful but I'd specifically love some project ideas and tutorials on exploit & malware development- I'd rather not use Metasploit additionally.
