从逆向走到可用利用 (Working Exploit) 的全链路工程化方法。 适用场景：拿到了二进制 + 漏洞点 + 目标环境，需要写出一个能稳定打通的 exploit（不是只能本地复现一下、远程一打就崩的脚本）。 覆盖三大方向：栈溢出 / 堆利用 / 内核 pwn。强调"CTF 本地通 → 真实远程稳定打通"的工程差距：libc 版本错配、堆喷射时序、SMEP/SMAP/KASLR、栈对齐、远程缓冲。 核心工具链：pwntools + GEF/pwndbg + ROPgadget/Ropper + one_gadget + libc-database + qemu-system 内核调试。 触发关键词：pwn、栈溢出、堆溢出、ROP、ret2libc、ret2csu、one_gadget、libc-database、堆利用、tcache、fastbin、unsorted bin、kernel pwn、kROP、SMEP、SMAP、KASLR、modprobe_path、pwntools、GEF、pwndbg。
Stack overflow and ROP playbook. Use when exploiting buffer overflows to hijack control flow via return address overwrite, ROP chains, ret2libc, ret2csu, ret2dlresolve, or SROP on Linux userland binaries.
Arbitrary write to RCE playbook. Use when you have an arbitrary write primitive (from heap exploitation, format string, or OOB write) and need to convert it into code execution by targeting GOT, hooks, _IO_FILE vtable, exit_funcs, TLS_dtor_list, modprobe_path, .fini_array, or C++ vtables.
Binary protection bypass playbook. Use when identifying and bypassing ASLR, PIE, NX/DEP, stack canary, RELRO, FORTIFY_SOURCE, CET, and MTE protections in ELF binaries to enable exploitation.
Format string exploitation playbook. Use when printf-family functions receive user-controlled format strings, enabling arbitrary stack reads (%p/%s), arbitrary memory writes (%n/%hn/%hhn), GOT/hook overwrites, and canary/libc/PIE leaks.
Heap exploitation playbook. Use when targeting ptmalloc2/glibc heap vulnerabilities including UAF, double free, overflow, off-by-one/null, and leveraging tcache/fastbin/unsortedbin attacks for arbitrary write or code execution.
Provides binary exploitation techniques for CTF challenges. Use when you already have a vulnerable native target or service and need to turn memory corruption or low-level primitives into code execution or privilege escalation, such as buffer overflows, format strings, heap bugs, ROP, ret2libc, shellcode, kernel exploitation, seccomp bypass, sandbox escape, or Windows/Linux exploit chains. Do not use it when the main blocker is understanding what the binary does; use reverse engineering first. D
