Threat Hunting & Detection Engineering

ACTION REQUIRED（读完后立刻执行）

NOW: 确认蓝队/狩猎授权与数据源范围（SIEM、EDR 导出）
NOW: 明确假说（hypothesis）再查数，避免无脑刷告警
NEXT: 工具与数据接入方式
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？
