Dns Lookup

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward DNS lookup helper that uses the standard dig tool, with the only notable risk being a user-directed system package install.

Install only if you are comfortable adding the bind-utils package through your system package manager. After installation, the skill performs DNS lookups with dig and does not request credentials or background access.

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
