Security audit

Monte Carlo

Security checks for vulnerabilities and agentic risk

Overview

The skill does not show malicious system access, but its finance/Monte Carlo reference claims do not match the generic placeholder content it actually provides.

Review this skill before relying on it for financial work. It appears locally contained and non-destructive, but its content is too generic for a Monte Carlo finance reference and should not be treated as authoritative modeling, risk, compliance, or investment guidance.

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 declared description says this is a 'Monte Carlo reference tool' for finance contexts, which implies content specifically about Monte Carlo methods or simulations in finance. The code only implements a command-line help/reference viewer with hardcoded, mostly generic text. While it is nominally a reference tool, the actual content is largely placeholder-style material and not substantively about Monte Carlo methods in finance. There are no undeclared sensitive actions or resource accesses, but the primary purpose as implemented is materially different from a genuine Monte Carlo finance reference tool.

Finding

The description and 'When to Use' section use generic phrases such as 'working with monte carlo,' 'need quick reference,' and 'need a checklist or guide' without defining specific trigger phrases, constraints, or exclusion conditions. This broad wording could overlap with ordinary finance discussions and cause unintended invocation of the skill.

Description-Behavior Mismatch

Confidence

Finding

The script is labeled as a Monte Carlo reference tool for finance, but it only prints generic boilerplate content and does not provide Monte Carlo simulation concepts, methods, formulas, or finance-specific guidance. This is dangerous because users may rely on it for domain-sensitive financial work and receive misleading or irrelevant information, creating a trust and integrity failure rather than a code-execution flaw.
