Signal Processing

Security checks for vulnerabilities and agentic risk

Overview

This skill is a signal-processing study reference and does not ask for unusual access or perform actions on the user's system.

Install this if you want a Chinese signal-processing reference. Review the included example code before running it in your own environment, as it is illustrative and may require scientific Python, GNU Radio, or DSP libraries.

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 title and introductory description are written in Chinese and present the skill as a Chinese-language knowledge system, with no indication that users may choose another language. This creates a language/locale policy concern because the skill implicitly mandates a specific language rather than offering an opt-in or documenting a justified region-specific restriction.
