分析 Office 365 审计日志以检测账户失陷
概述
商业邮件欺诈（Business Email Compromise，BEC）攻击通常会在 Office 365 审计日志中留下痕迹：可疑的收件箱规则创建、将邮件转发到外部地址、邮箱委托更改以及未经授权的 OAuth 应用授权。本 skill 使用 Microsoft Graph API 查询统一审计日志，枚举各邮箱的收件箱规则，检测转发配置，并识别账户失陷指标。
前置条件
- Azure AD 应用注册，具备
AuditLog.Read.All、MailboxSettings.Read、Mail.Read（应用权限） - Python 3.9+ 及
msal、requests库 - 用于认证的客户端密钥或证书
- 全局读取者（Global Reader）或安全读取者（Security Reader）角色
步骤
- 使用 MSAL 客户端凭据流向 Microsoft Graph 进行身份认证
- 查询统一审计日志中的可疑操作（Set-Mailbox、New-InboxRule）
- 枚举各邮箱的收件箱规则并标记转发规则
- 检测邮箱委托更改（Add-MailboxPermission）
- 识别向可疑应用程序的 OAuth 授权
- 检查审计日志中的可疑登录模式
- 生成包含时间线的失陷指标报告
预期输出
- JSON 报告，列出转发规则、委托更改、OAuth 授权以及带有风险评分的可疑审计事件
- 失陷指标及受影响邮箱的时间线
