How it fires

How this skill gets triggered: by you, by Claude, or both.

  • Fires itselfAuto-invocation. Claude auto-loads it when your prompt matches the work.Auto-invocation is when the right skill fires by itself at the right moment, driven by a FLOW.md router and a hook, instead of you invoking it by name. It is the difference between a skill being installed and a skill actually getting used.Read the full definition →

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

| 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?
