A comprehensive, week-by-week plan from where you are now (start of pwn.college) to a working reverse engineer and security researcher, specialising in Linux driver security and Linux malware. 72 weeks mapped in detail; Stage 6 then continues open-ended for years.
At about 3 focused hours on weekday evenings, one row here is roughly one calendar week. Some weeks will take two; that's expected. Consistency over the long run beats speed.
Built around your background. You're an embedded-Linux engineer and kernel contributor, so the C, Linux-internals and driver-writing work is deliberately fast or reframed rather than taught from zero. Your edge is that Stages 3, 5 and 6 sit on skills most security learners spend years acquiring. Spend the saved time on the security mindset and on exploitation, which are the genuinely new parts.
