Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Apify Google Search helper that discloses its external API use and does not include hidden persistence or local code execution.

Before installing, users should understand that searches and related parameters are sent to Apify and require an APIFY_TOKEN, which may consume Apify credits and expose search queries to that provider. Set maxItems or maxPagesPerQuery when controlling cost or volume matters, and avoid using customMapFunction unless you understand the remote actor behavior.

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
