Documentation

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
  • malware-analysis/:样本侧 IOC → 本 skill 落地检测
  • 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

工具用途
Sigma CLI / sigmac规则转换
YARA文件/内存
SIEM(ELK/Splunk 等)查询
osquery端点狩猎
Atomic Red Team检测验证(实验室)

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?

Individual skills in this repo

This repo contains 20 individual skills — each has its own dedicated page.

api-security

Use for authorized security assessment of REST, GraphQL, WebSocket, or SOAP APIs, including discovery, authentication, authorization, rate-limit, and CI/CD testing.

apk-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。

attack-chain

Use 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.

binary-diff

|

binary-ninja-reverse

Use 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.

browser-automation

|

browser-extension-reverse

Use for authorized reverse engineering of browser extensions (Chrome/Firefox) including manifest analysis, background workers, and extension-based credential or traffic logic recovery.

case-review

Reviews 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.

cloud-k8s

Use for authorized cloud, container, and Kubernetes security assessment including metadata SSRF, IAM misconfig, container escape paths, and cluster RBAC review.

code-audit

Use for authorized source-code security review and SAST workflows including Semgrep, CodeQL patterns, dangerous API hunting, and fix verification.

ctf-sandbox

Thin PRIMARY for CTF / AWD / 靶场 multi-type orchestration. Hands off to the sidecar CTF-Sandbox-Orchestrator. Use when the user says CTF, AWD, 靶场, or 比赛题 and no more specific pwn/APK/IDA route already won.

database-security

Use for authorized database security assessment covering PostgreSQL/MySQL/MSSQL/Mongo/Redis exposure, authz, UDF/command paths, and misconfiguration review.

diagram-generator

generate, refine, validate, and render diagrams from natural language, notes, code snippets, schemas, tables, or existing diagram source. use for flowcharts, swimlanes, sequence diagrams, state diagrams, er diagrams, class diagrams, architecture/c4-style diagrams, dependency graphs, gantt charts, mind maps, user journeys, sankey-style flows, org charts, network graphs, and other visual models. supports mermaid by default, graphviz dot for complex graph layout, plantuml for uml-heavy engineering diagrams, and svg output when direct markup is more reliable.

digital-forensics

Use for authorized digital forensics including memory dumps, disk timelines, PCAP investigation, artifact triage, and IR evidence preservation.

docs-generator

dotnet-reverse

.NET / C# 二进制逆向。当目标是 .NET assembly(PE 头含 CLR、.exe/.dll 托管程序)、C# 编译产物(含 NativeAOT)、红队 Sharp* 工具(Rubeus / SharpHound / SharpHound 等)、.NET 混淆程序(ConfuserEx / SmartAssembly / Babel / Eazfuscator)、.NET loader / info-stealer / 套壳 malware 时使用。优先用 dnSpyEx + de4dot,需要 AI 直接操作时联动 dnSpy MCP。不用于纯 native 二进制(走 reverse-engineering / ida-reverse)。
