Data Analyzer

Security checks for vulnerabilities and agentic risk

Overview

This is a straightforward data-analysis skill whose file-writing examples are disclosed and purpose-aligned, with no evidence of hidden execution, persistence, credential access, or exfiltration.

Before using this skill, run analysis only on datasets you intend the agent to process and direct outputs to an isolated folder to avoid overwriting files or creating sensitive derived reports in shared locations.

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

Vague Triggers

Medium
Category

Confidence
93% confidence
Finding

The activation guidance uses generic phrases such as 'User wants to analyze a dataset' and 'Generate charts and visualizations' without narrowing context, explicit trigger phrases, or exclusion conditions. These descriptions overlap with common analytics requests and make it unclear when this skill should or should not activate.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The skill repeatedly shows commands that write reports, charts, and transformed datasets to disk, but it does not warn that execution will create or overwrite files at the provided output paths. In agent contexts, missing disclosure about filesystem side effects can lead to unintended data exposure, clobbering existing files, or writing sensitive derived artifacts to insecure locations.
