Security checks for vulnerabilities and agentic risk

Overview

This skill is a small Portuguese-language guide for sending user-directed chat messages through OpenClaw, with no hidden code, persistence, or unrelated behavior found.

Install only if you want Portuguese guidance for OpenClaw chat sending. Before using it, confirm the channel, account, recipient ID, and message contents; use `--dry-run` for complex payloads and avoid sending secrets or sensitive personal data unless that is intentional.

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

Missing User Warnings

Medium
Category

Confidence

Finding

The skill provides procedural guidance for sending messages, media, and structured payloads to external chat platforms but does not warn users that content will be transmitted outside the local environment and may expose personal, confidential, or regulated data. In an agent setting, this omission increases the risk of accidental data exfiltration because users may treat the skill as routine automation rather than an external communication action.

Natural-Language Policy Violations

Low

Not specified by scanner
Confidence
94% confidence
Finding

The natural-language instructions and description are presented in Portuguese throughout the file, but there is no indication that the user opted into that language or that the skill is intentionally limited to a Portuguese-speaking audience. This can violate language/locale policy when a skill forces a specific language without user choice or justification.
