## 说明

1. 安装依赖:`pip install boto3 requests`
2. 使用 AWS CLI 或 boto3 查询 CloudTrail 的 S3 Data Events。
3. 建立访问基线:按小时请求量、每用户对象计数、源 IP 历史记录。
4. 检测异常:
   - 非工作时间访问(本地时间 8am-6pm 以外)
   - 批量下载:单个主体在 1 小时内 >100 次 GetObject 调用
   - 最近 30 天内未见过的新源 IP
   - ListBucket 枚举峰值(侦察指标)
5. 生成优先级排序的发现报告。

```bash
python scripts/agent.py --bucket my-sensitive-data --hours-back 24 --output s3_access_report.json
```

## 示例

### CloudTrail S3 Data Event
```json
{"eventName": "GetObject", "requestParameters": {"bucketName": "sensitive-data", "key": "financials/q4.xlsx"},
 "sourceIPAddress": "203.0.113.50", "userIdentity": {"arn": "arn:aws:iam::123456789012:user/analyst"}}
```
