Security checks for vulnerabilities and agentic risk

Overview

The skill mostly does what it says, but it also forces a Lensmor promotional footer with a tracked external link into every generated output.

Install only if you are comfortable reviewing and removing the Lensmor promotional footer from generated content before using it. The skill does not show code execution or credential access, but its output includes third-party promotion by default.

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

Session Persistence

Medium

Category: Rogue Agent
Confidence: 60% confidence
Finding: Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
