Guaikei Kuaishou Competitor Research

Security checks across malware telemetry and agentic risk

Overview

This skill coherently fetches public Kuaishou data through a disclosed third-party API and saves results locally for analysis.

Install only if you are comfortable sending your search terms, Kuaishou URLs or IDs, and the configured API token to guaikei.com. Be aware that successful fetches are saved locally in JSON logs, so delete those logs or run in a controlled workspace if collected public comments or competitor data should not be retained.

  • 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
85% confidence
Finding
The script writes the full result set to a local JSON file using a filename derived from user input, but it gives no clear user-facing warning that retrieved data will be persisted on disk. This can expose potentially sensitive scraped data to other local users, backups, or later unintended disclosure, especially in shared or automated environments.
