Exploit Dev — Your First Exploit

Everything so far converges into your first real working exploit. We take a vulnerable program and walk the whole recipe end to end: trigger the crash, find the exact offset with a cyclic pattern, prove you control RIP, find a target function, then ret2win — redirect execution into win() and pop a shell. You write the complete pwntools script, handle the 16-byte alignment gotcha, and learn the common failures and their fixes.
