Data Analysis 1

Security checks for vulnerabilities and agentic risk

Overview

This is a coherent data-analysis guidance skill with no executable code, network endpoints, persistence, or hidden privilege behavior found.

This skill appears safe to install as a data-analysis reference aid. Users should still review any separate SQL queries, scripts, spreadsheet automations, or related skills they ask an agent to run, because those user-directed actions may access or transform sensitive data even though this skill itself does not add persistence or external data sharing.

A.I.G

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

Self-Modification

Finding

Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.
