Data Analyzer From Bilibili

Security checks for vulnerabilities and agentic risk

Overview

This is a simple data-analysis prompt skill with broad Chinese trigger text and noisy reference notes, but no executable code or hidden high-impact behavior.

Before installing, consider whether you want a Chinese-language data-analysis helper that may activate on general data or spreadsheet requests. Review uploaded data normally, but this artifact does not add executable code, persistence, credential access, or hidden system changes.

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
  • 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
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
86% confidence
Finding

The user-facing description and trigger examples are written only in Chinese, while no language-selection or opt-in behavior is documented. This can violate language/locale policy when a skill implicitly constrains interaction to a specific language without clearly offering alternatives or explaining why the locale is required.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The trigger phrases are broad everyday terms like '分析数据', '统计一下', and references to CSV/Excel uploads, which can cause the skill to activate during ordinary conversation rather than only when explicitly intended. In an agent system, overbroad activation increases the chance of unintended context capture, incorrect tool routing, and execution of a low-quality auto-generated skill on unrelated user input.
