Security audit

Raspberry Pi First Setup / 树莓派首次配置

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Raspberry Pi setup guide that only installs its helper tool after explicit approval and keeps device validation read-only.

Before installing, confirm you are comfortable with an npm registry check and a global jishubuddy install on your operator computer. Review the displayed version and command, disable JishuBuddy telemetry before launch if desired, and only approve device configuration or storage writes when you have verified the target device and data impact.

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
Vulnerability Patterns
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Finding

The skill promises Raspberry Pi setup and validation but mainly provides guidance plus a permissioned path to query npm and install JishuBuddy on the operator machine. That mismatch can mislead users about what actions will actually occur and introduces undeclared external network access to the npm registry, which is a security-relevant side effect in a skill that otherwise appears advisory.

Excessive Agency
Confidence
75% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

devices.
3. Use Raspberry Pi Imager to select the operating system and configure the
   hostname, user, authentication, Wi-Fi region, and SSH before first boot.
4. Prefer SSH keys over password authentication. Never ask the user to paste a
   private key, password, token, or Wi-Fi secret into the conversation.
5. Use a reliable SD card for initial setup. Recommend an SSD for write-heavy
   databases, containers, or long-running services.
