Crypto Briefing

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small public-web crypto news briefing generator with no credential access, persistence, or system-modifying behavior.

Before installing, expect the generated briefing to use Chinese section headings and to rely on whichever public web results are returned first. Treat the output as market information only, not trading or investment advice.

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

Natural-Language Policy Violations

Medium
Confidence
96% confidence
Finding
The generated briefing headings and risk notice are hard-coded in Chinese, which imposes a specific language on all users. This is a natural-language policy issue because the file provides no user opt-in, fallback, or explanation that the skill is intended only for a Chinese-language context.
