Security audit

Agente Portugues

Security checks for vulnerabilities and agentic risk

Overview

This is a Portuguese exam-tutoring skill with no code, network access, credential handling, persistence, or destructive behavior.

Before installing, expect this skill to activate for many Portuguese, grammar, literature, and writing-study requests, including Antonio-specific tutoring contexts. It appears safe from a security perspective, but users who want narrower routing may prefer more explicit FUVEST-only activation wording.

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

Finding

The activation conditions are broad enough to match many ordinary study interactions, such as mentions of grammar, literature, writing, or any orchestrator-opened Portuguese session. This can cause the skill to activate outside narrowly intended contexts, increasing the chance of unnecessary invocation, routing mistakes, or interference with other educational agents in the same ecosystem.
