Threat Hunting & Detection Engineering

ACTION REQUIRED（读完后立刻执行）

  1. NOW: 确认蓝队/狩猎授权与数据源范围（SIEM、EDR 导出）
  2. NOW: 明确假说（hypothesis）再查数，避免无脑刷告警
  3. NEXT: 工具与数据接入方式
  4. ACT: 假说 → 查询 → 验证 → 规则化

适用场景

  • 威胁狩猎（hypothesis-driven）
  • Sigma / YARA 检测工程
  • 告警调优、误报分析
  • 与 malware-analysis/：样本侧 IOC → 本 skill 落地检测
  • 与 digital-forensics/：案件伪影 → 横向狩猎

工作流

1. 建假说

例：攻击者用 living-off-the-land 做横向
→ 数据源：Sysmon 1/3/10、Windows Security 4624/4648
→ 成功标准：发现异常父进程或罕见账户日志源

2. 查询与堆叠

□ 基线：正常管理员行为时段与主机
□ 异常：新服务、编码 PowerShell、异常出站
□ 关联：同账号多主机短时登录

3. 规则化

# Sigma 骨架见 malware-analysis；本 skill 强调：
# - 误报面
# - 数据源字段映射
# - 响应 playbook 链接

4. 验证

□ 原子测试（Atomic Red Team）仅在授权实验室
□ 回放历史日志验证召回

工具链

参考

  • references/hunting-loop.md
  • ../malware-analysis/references/yara-sigma-rules.md
  • ../digital-forensics/

路由上下文

上游: MASTER R27 下游: 确认入侵 → forensics；恶意样本 → malware-analysis MUST NOT: 在无授权生产环境跑攻击模拟

任务完成自检

  • [ ] 是否有明确假说与结论？
  • [ ] 规则是否注明误报与数据源？
  • [ ] Checklist？

  • Capk-reverse在 CLI 环境下做 Android APK 逆向时使用。适用于 APK 解包、Java 反编译、smali 修改、重打包、Frida 动态 Hook，以及按需切换到 so/native 分析。优先使用本机已安装的 jadx、apktool、frida、adb、ida-reverse、radare2。
  • Cattack-chainUse for authorized multi-stage attack-path planning and orchestration when a task spans reconnaissance, initial access, privilege escalation, lateral movement, or impact assessment. Route single-stage tasks directly to their specialist skill.
  • Abinary-diff跨版本符号迁移与二进制差分。当你有旧版本的符号/逆向结果，需要快速迁移到新版本时使用。 适用场景：内核缺 PDB 用旧版符号推导、程序更新后批量迁移函数名、应用更新后快速定位新偏移。 核心方法：用 LLM 做结构化差异比对，程序化输入输出，成本极低（200 函数 ~1 元）。 触发关键词：符号迁移、bindiff、跨版本、PDB 缺失、函数偏移迁移、symbol migration、binary diff、版本对比。
  • Abinary-ninja-reverseUse for authorized binary analysis in Binary Ninja, including HLIL/MLIL/LLIL inspection, strings/imports/exports, cross-references, types, patch review, Python API automation, and optional Binary Ninja MCP or localhost HTTP integration.
  • Abrowser-automation统一自动化入口。覆盖浏览器自动化（Playwright）和 Windows 桌面应用自动化（OpenReverse）。 浏览器场景：打开网页、点击、填表、爬取、截图、自动化登录、渗透页面交互。 桌面场景：操作 IDA/x64dbg 等 GUI 工具、Windows UI Automation、视觉驱动交互、桌面应用网络抓包。 触发关键词：浏览器自动化、桌面自动化、打开网页、填表、爬取、截图、自动化登录、Playwright、agent-browser、headless、OpenReverse、UIA、CUA、桌面操作、Windows 自动化。
  • Abrowser-extension-reverseUse for authorized reverse engineering of browser extensions (Chrome/Firefox) including manifest analysis, background workers, and extension-based credential or traffic logic recovery.
  • Acase-reviewReviews a reverse-skill case package for scope readiness, Evidence to Finding to Path traceability, work item coverage, timeline references, and optional artifact hash integrity before report handoff.
  • 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.
