pwn-chain

pwn-chain is a skill for Claude Code, Codex from SeaOf0/dsh-redteam-model. It costs 271 tokens per session (3,060 once invoked), scanned A, a copy of pwn-chain, MIT.

A workflow for turning a known memory-safety bug in a program into a working exploit. It covers stack, heap, and Linux-kernel exploitation.

In plain words
What is it for?
Use it to exploit known stack overflows, use-after-free bugs, double frees, and similar flaws, including Linux kernel driver bugs, with tools such as pwntools and debuggers.
Why use it?
An exploit that works locally can fail remotely because of different libraries, memory protections, timing, or system settings; this focuses on making it work reliably in the target environment.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

pwn-chain scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 193 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ACTION REQUIRED(读完后立刻执行)

  1. NOW: 读取 ../field-journal/precedent-reverse.md — 确认本 skill 的操作是已授权的常规操作
  2. NOW: 确认当前任务是否命中本 skill 的适用范围
  3. NEXT: 读取 ../tool-index.md,校验工具可用性和实际路径
  4. NEXT: 缺工具时调用 bootstrap,不要猜路径
  5. ACT: 进入"工作流"第一步并执行,不要停在确认状态

从漏洞点到 Working Exploit (Pwn Chain)

适用范围

当任务属于以下场景时使用本 skill:

  1. 拿到二进制 + 已知漏洞点 — 静态/审计/fuzz 已经找到溢出/UAF/double free,需要从触发到拿 shell
  2. CTF 题已经本地通了,远程打不通 — 远端环境差异导致脚本失效,需要稳定化
  3. 真实目标的二进制利用 — SRC / 红队场景下,已经识别到内存损坏漏洞,需要构造 RCE
  4. Linux 内核驱动的 ioctl bug — 用户态触发,目标是提权到 root

前提:你已经知道"哪里炸了"。本 skill 不负责发现漏洞(那是 fuzzing / 审计),只负责"从漏洞点写出 exploit"。

与其他 skill 的分工

场景 用什么
识别 custom VM / anti-debug / 复杂 obfuscation reverse-engineering/
从零打开二进制做静态分析 ida-reverse/radare2/
有漏洞点,写 exploit 打通远程 本 skill
把 pwn 拿到的 shell 整合进完整攻击链 attack-chain/(下游)

reverse-engineering/ 关注"理解程序在干什么"(模式识别、协议还原、解 CTF 题里的奇怪机制);本 skill 关注"把已经看懂的漏洞变成可执行的攻击"。两者经常配套使用,但分工清晰。

核心工作流

Step 1: 确认漏洞类型 + 保护机制
   ├─ checksec ./vuln(NX / Canary / PIE / RELRO / Fortify)
   ├─ file ./vuln  + readelf -d ./vuln
   ├─ 漏洞分类:栈溢出 / 格式化字符串 / 堆 (UAF/DF/OF) / 整数 / 竞态 / 内核
   └─ → 决定走哪个 references/

Step 2: 选择利用策略
   ├─ NX 关 + 无 ASLR → 直接 shellcode
   ├─ NX 开 + 给 libc → ret2libc / one_gadget
   ├─ NX 开 + 不给 libc → leak 后 libc-database 反查
   ├─ 堆 → 按 glibc 版本对应技术 (tcache/fastbin/unsorted/large)
   └─ 内核 → commit_creds / modprobe_path / core_pattern

Step 3: 准备 libc + gadget
   ├─ libc-database:./find puts 0x6f0
   ├─ ROPgadget --binary ./libc.so.6 --only "pop|ret"
   ├─ one_gadget ./libc.so.6
   └─ 计算 base:leak_addr - libc.sym['puts']

Step 4: 写 pwntools 模板(本地 process)
   ├─ context.binary = ELF('./vuln')
   ├─ p = process('./vuln')  /  p = gdb.debug('./vuln','b *main+xx')
   ├─ payload = cyclic(N) + p64(ret) + ...
   └─ p.interactive()

Step 5: 本地通
   ├─ 反复 attach + 看寄存器 + 调 offset
   ├─ 用 pwndbg/GEF 的 vmmap / heap / bins / telescope
   └─ 跑通后切 remote()

Step 6: 远程稳定化
   ├─ libc 偏移:用 leak 反查 libc-database,不要拍脑袋
   ├─ 栈对齐:16-byte 不对齐 → movaps 崩 → 加一个 ret gadget
   ├─ 远程网络延迟 → recvuntil 精确锚字符串,禁用模糊 sleep
   ├─ 远程缓冲:sendlineafter 比 sendline 更稳
   ├─ 堆喷成功率:放大 spray 数量 + 留 padding chunk 防合并
   └─ 多次跑:写 while True 验证成功率 ≥ 95%

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
