Security audit

Instagram Collector

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward Instagram metrics collector that uses Apify as disclosed, with privacy and compliance considerations users should understand before use.

Install only if sending Instagram handles and related public profile/post data to Apify is acceptable for your organization. Confirm Apify terms, token scope, expected costs, and any Instagram scraping or privacy compliance requirements before using it in a production audit pipeline.

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

Missing User Warnings

Confidence

Finding

The skill explicitly sends Instagram handles and scraping requests to Apify, but it does not warn users that their input and requested profile data are transmitted to a third-party service. This creates a transparency and privacy issue because users may assume the skill operates locally or only within the primary platform, and organizations may unknowingly violate disclosure or data-handling requirements.

External Transmission

Medium
Category
Data Exfiltration
Confidence
86% confidence
Finding

The skill depends on an external endpoint at api.apify.com to perform profile scraping, which means user-supplied handles and requested profile data leave the local trust boundary. In context this is part of the intended functionality, but it still introduces third-party data exposure, compliance, availability, and supply-chain risk if not clearly disclosed and governed.
