# Email Security & Phishing Analysis
## ACTION REQUIRED(读完后立刻执行)
1. `NOW`: 确认授权(分析样本邮件 / 租户配置评审)
2. `NOW`: 不向真实用户二次投递恶意样本
3. `ACT`: 头认证 → 内容/URL → 附件沙箱 → 租户控制面建议
## 适用场景
- 钓鱼邮件拆解与 IOC
- SPF/DKIM/DMARC 配置评估
- BEC 商务邮件欺诈模式
- OAuth 应用钓鱼 / 邮箱令牌滥用(联合 llm/cloud 身份)
- 安全意识演练设计(授权)
## 工作流
```text
□ 完整原始头:Received 链、From/Return-Path 一致性
□ SPF/DKIM/DMARC 对齐结果
□ URL 沙箱与附件静态(联合 malware-analysis)
□ 仿冒品牌与回复地址差异
□ 租户:反钓鱼策略、外部标记、MFA、OAuth app 同意
```
## 工具链
| 工具 | 用途 |
|------|------|
| 邮件客户端「查看源」 | 头 |
| dig/nslookup | SPF/DMARC 记录 |
| urlscan / 沙箱 | 链接与附件 |
| 租户管理中心 | 策略 |
## 参考
- `references/email-auth-checklist.md`
- `../malware-analysis/` `../attack-chain/`(钓鱼阶段) `../windows-ad/`(令牌)
## 路由上下文
**上游**: MASTER R36
**MUST NOT**: 未授权对第三方域群发测试钓鱼
## 任务完成自检
- [ ] 头认证结论是否完整?
- [ ] IOC 是否可检测化(联合 threat-hunting)?
