MBA

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only MBA learning skill whose local note storage is disclosed and aligned with its purpose.

Before installing, be aware that the skill may create ~/mba/ and save progress, notes, exercises, and case analyses there. Avoid putting confidential business plans, financials, or personal career information in those files unless you are comfortable storing them locally.

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

Confidence
70% confidence
Finding
Hidden instructions were detected in comments or invisible text. These could contain malicious directives. Manual review is recommended.

Missing User Warnings

Medium
Confidence
95% confidence
Finding
The skill explicitly instructs tracking progress, case studies, exercises, and notes under ~/mba/ without warning the user that local files will be created and retained. This creates a privacy and data-handling risk because users may store sensitive business plans, financial analyses, or personal career information on disk unintentionally.

Vague Triggers

Low
Confidence
88% confidence
Finding
The activation guidance says the skill applies whenever a user wants 'better business decisions' and spans entrepreneurs, professionals, career changers, and students. This is a very broad natural-language scope without explicit trigger constraints or exclusion examples, increasing the chance of unintended invocation for generic advice requests.
