macOS / Mach-O Reverse Engineering

ACTION REQUIRED（读完后立刻执行）

  1. NOW: 读取 ../field-journal/precedent-reverse.md
  2. NOW: 确认目标为 macOS/Mach-O/App bundle（iOS IPA → mobile-reverse/）
  3. NEXT: tool-index；jtool2/lldb 等
  4. ACT: 签名与装载信息 → 静态 → 动态（lldb/Frida）

适用场景

  • Mach-O 可执行文件 / dylib / framework
  • .app bundle、LaunchAgent/Daemon
  • Objective-C / Swift 符号与 runtime
  • 公证/签名、Hardened Runtime、TCC 相关行为分析
  • macOS 恶意软件静态/动态分析（联合 malware-analysis）

工作流

1. 包体与签名

file target
codesign -dv --verbose=4 target
spctl -a -vv target 2>&1
otool -L target

2. 静态

□ class-dump / swift-demangle / Hopper / Ghidra / IDA
□ 字符串与 XPC 服务名、TCC 敏感 API
□ LC_LOAD_dylib 依赖与 rpath

3. 动态

□ lldb / Frida
□ fs_usage / log stream 观察
□ 网络：联合 protocol-reverse 或代理

工具链

参考

  • references/macho-triage.md
  • ../mobile-reverse/（iOS） ../ghidra-reverse/ ../malware-analysis/

路由上下文

上游: MASTER R31 下游: iOS → mobile-reverse；通用样本 → malware-analysis

任务完成自检

  • [ ] 是否记录签名/Hardened Runtime 状态？
  • [ ] 是否有地址级/符号级结论？
  • [ ] Checklist？

  • Acloud-k8sUse for authorized cloud, container, and Kubernetes security assessment including metadata SSRF, IAM misconfig, container escape paths, and cluster RBAC review.
  • Acode-auditUse for authorized source-code security review and SAST workflows including Semgrep, CodeQL patterns, dangerous API hunting, and fix verification.
  • Acompetition-ad-certificate-abuseInternal downstream skill for ctf-sandbox-orchestrator. CTF-sandbox workflow for AD CS, certificate templates, enrollment rights, EKUs, SAN controls, PKINIT, certificate mapping, and cert-based privilege paths. Use when the user asks about ESC-style abuse, certificate templates, enrollment agents, EKUs, SAN or subject controls, smartcard or PKINIT logon, CA policy, or how an issued cert turns into accepted privilege. Use only after `$ctf-sandbox-orchestrator` has already established sandbox assumptions and routed here.
  • Acompetition-agent-cloudInternal downstream skill for ctf-sandbox-orchestrator. CTF-sandbox workflow for AI-agent, prompt-injection, MCP or toolchain, cloud, container, CI/CD, and supply-chain challenges. Use when the user asks to analyze prompt-to-tool flows, retrieval poisoning, mounted secrets, deployment drift, runtime-vs-manifest mismatches, registry provenance, or CI-produced artifacts under sandbox assumptions. Use only after `$ctf-sandbox-orchestrator` has already established sandbox assumptions and routed here.
