Security audit

Aws S3

Security checks for vulnerabilities and agentic risk

Overview

This is a coherent AWS S3 SDK bundle skill, but users should pin and verify the remote package they install and keep dependencies updated.

Install only from a pinned, verified tarball for the version you intend to use, and run the skill with least-privilege AWS credentials limited to the required S3 buckets and actions. Review dependency updates before rebuilding the bundle.

A.I.G

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Data Exfiltration
Confidence
50% confidence
Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
