Bitcoin Market Intelligence

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple Markdown guide for a paid Bitcoin data API, with the payment behavior and prices disclosed.

Install only if you intend to let your agent use lnget with a funded Lightning node. The health endpoint is free, but the market brief and latest alert examples are paid calls that spend 100 sats and 50 sats respectively.

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

Missing User Warnings

Medium
Confidence
97% confidence
Finding
The usage examples explicitly show commands that trigger paid Lightning requests, but they do not warn the user that running them will spend real sats from a connected Lightning node. In a skill aimed at automation and agents, this is especially risky because users may copy-paste or programmatically execute the examples, causing unintended financial loss.
