Web Research

Security checks for vulnerabilities and agentic risk

Overview

This is a simple web-research guidance skill with no code, persistence, credential access, or hidden behavior, though users should be aware it favors Chinese-language sources by default.

Install this if you want an agent to structure web research and cross-check sources. For global, legal, medical, security, or highly technical topics, ask the agent to prioritize authoritative sources in any language rather than Chinese-language sources by default.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Finding

The trigger conditions are broad enough that the skill may activate for many generic requests involving searching, verification, or feasibility checks. This can cause unintended invocation, leading the agent to perform web access or apply this skill when the user did not clearly request it, increasing the risk of scope creep, irrelevant browsing, or policy bypass through unexpected tool use.

Natural-Language Policy Violations

Finding

Hard-coding a preference for Chinese-language resources without user opt-in can bias retrieval quality and completeness, especially when the most authoritative or current materials are in other languages. In a web-research skill, this may systematically suppress better sources and distort results, which is a security-relevant reliability issue when users depend on accurate external information.
