Security checks across malware telemetry and agentic risk

Overview

This skill is a disclosed Kuaishou public-data research tool that calls a third-party API and saves local result logs, with no evidence of hidden execution, credential theft, or destructive behavior.

Install only if you are comfortable sending Kuaishou keywords, profile URLs, video URLs, and query parameters to guaikei.com using your GUAIKEI_API_TOKEN. Treat the generated logs as sensitive work history if your research targets, competitor monitoring, or comment datasets should remain private, and delete logs when no longer needed.

  • 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
87% confidence
Finding
The README states that all task results are automatically saved to a local logs/ directory, and this tool accepts user-supplied keywords, profile URLs, and video URLs. Even if the data is public, persisted logs can capture sensitive research targets, monitoring subjects, and query history, creating privacy, confidentiality, and operational security risks if the host is shared, backed up, or compromised.

Missing User Warnings

Medium
Confidence
80% confidence
Finding
The script writes fetched comment data to a local file without explicit user notice or consent, creating an unannounced persistence channel for potentially sensitive or regulated content. In a data-collection skill, silent retention increases privacy, compliance, and data-handling risk, especially on shared hosts or multi-user environments where stored files may be later accessed or redistributed.

Missing User Warnings

Medium
Confidence
90% confidence
Finding
The CLI persists full search output to a local JSON file named with user-supplied keyword data, but the user is not clearly warned that results will be stored on disk. In this skill’s context, the output can include competitive research data and fetched public-platform content, creating unintended local data retention and possible disclosure to other local users, backup systems, or downstream tooling.
