Instagram Growth

Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed Instagram growth strategy skill with no executable code, persistence, credential handling, or hidden data movement.

Before installing, be aware that this skill may route work to several companion marketing skills and asks the agent to use brand, audience, strategy, and Instagram Insights data you provide. Review any separate publishing or scheduling skill before allowing it to post or schedule content on an Instagram account.

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

Finding

The manifest description says the skill routes to a narrower set of companion skills, but the body later expands orchestration to additional executors such as viral-reverse-engineering, cross-platform-repurposing, and scheduling-related skills. This creates a capability mismatch that can mislead reviewers, policy gates, or users about what downstream actions the skill may trigger, weakening trust and control over agent behavior.
