Radar CNPJ

Security checks for vulnerabilities and agentic risk

Overview

This skill is a clearly scoped Radar CNPJ integration that uses external API calls for its stated company-checking purpose and includes explicit user-approval rules for paid or personal-data actions.

Before installing, be aware that queries go to radar-cnpj.com and that paid lookups, credit tokens, partner names, phone numbers, and email reveals require careful user approval and legitimate use. The skill itself tells the agent not to spend balance, reveal personal data, or log tokens without user control.

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
