说明
- 安装依赖：
pip install boto3 requests - 使用 AWS CLI 或 boto3 查询 CloudTrail 的 S3 Data Events。
- 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。
- 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）
- 生成优先级排序的发现报告。
python scripts/agent.py --bucket my-sensitive-data --hours-back 24 --output s3_access_report.json
