analyzing-cloud-storage-access-patterns

Detect abnormal access in AWS S3, GCS, and Azure Blob Storage by analyzing CloudTrail Data Events, GCS audit logs, and Azure Storage Analytics for after-hours bulk downloads, new-IP access, and API-call spikes (e.g. GetObject) via statistical baselines and time-series anomaly detection. Use when investigating suspected cloud data exfiltration or building related detection rules.

Low

W011: Third-party content exposure detected (indirect prompt injection risk).

What this means

The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.

Why it was flagged

In `scripts/agent.py`, the runtime workflow executes `aws cloudtrail lookup-events` in `query_cloudtrail_s3_events()` and then reads/ingests the returned CloudTrail `CloudTrailEvent` JSON fields (e.g., `sourceIPAddress`, `requestParameters.bucketName/key`, `userIdentity.arn`) from that external log content into `s3_events` for anomaly detection.
