ctf-pwn

Comprehensive binary exploitation reference covering stack overflows, ROP chains, heap attacks, kernel pwn, and advanced CTF techniques. Quick reference for binary exploitation (pwn) CTF challenges. Each technique has a one-liner here; see supporting files for full details. Python packages (all platforms): Linux (apt): macOS (Homebrew): Ruby gems (all platforms): Manual install: Quick decision tree: ret2win with magic value: Overflow -> ret (alignment) -> pop rdi; ret -> magic -> win(). Stack alignment: SIGSEGV in movaps = add extra ret gadget. Offset: buffer at rbp - N , return at rbp + 8 , total = N + 8. Input filtering: assert payload avoids memmem() banned strings. Gadgets: ROPgadget --binary binary | grep "pop rdi" , or pwntools ROP() for hidden gadgets in CMP immediates.
