Qq Music

Security checks for vulnerabilities and agentic risk

Overview

This skill is a read-only QQ Music analysis helper with disclosed limits and no artifact-backed evidence of persistence, hidden behavior, or unsafe automation.

Install this as a public QQ Music analysis helper. Use it for summaries and trend checks, and avoid giving it account access unless you specifically want personal page information organized; it should not be used for downloads, bulk scraping, bypassing checks, or automatic account actions.

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
  • Rogue AgentSelf-Modification, Session Persistence
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The description activates on essentially any request involving QQ Music content, which is broader than a narrowly scoped skill trigger. Overbroad activation can cause the agent to invoke this skill in contexts the user did not intend, increasing the chance of unnecessary browsing, data handling, or policy-bound automation on a third-party site.

Content

No source excerpt is available for this finding.

Session Persistence

Medium
Category
Rogue Agent
Confidence
75% confidence
Finding

Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
