- Two successful sign-ins from geographically impossible locations within 15 minutes.
|
||||
- MFA challenge volume increased abnormally before final success.
|
||||
- User confirmed they did not initiate overseas login.
|
||||
|
||||
## 研判过程摘要
|
||||
|
||||
1. 确认告警场景与核心风险：User account showed impossible travel between Shanghai and Amsterdam, followed by repeated MFA prompts and successful sign-in.
|
||||
2. 提取关键证据并交叉验证：Two successful sign-ins from geographically impossible locations within 15 minutes.
|
||||
3. 对照关联 playbook / KB 复核告警模式与处置路径。
|
||||
4. 基于关键证据与场景模式完成结论判定：真报。
|
||||
|
||||
## 结论依据
|
||||
|
||||
- 结论为真报。
|
||||
- 最关键依据：Two successful sign-ins from geographically impossible locations within 15 minutes.
|
||||
- 补充依据：MFA challenge volume increased abnormally before final success.
|
||||
|
||||
## 处置建议
|
||||
|
||||
- 复核登录来源、MFA 事件和后续邮箱规则或 OAuth 变更。
|
||||
- 若存在账号接管迹象，立即执行会话失效和凭据重置。
