Sortino

Security checks for vulnerabilities and agentic risk

Overview

This skill does not show malware-like behavior, but its Sortino finance reference content is materially generic and may mislead users expecting accurate Sortino guidance.

Review this before installing if you need reliable finance guidance. The skill appears locally contained and low-risk from a system-security perspective, but its outputs should not be treated as an accurate Sortino ratio reference without independent verification.

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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The skill's activation guidance is very broad and generic, such as 'need quick reference' or 'troubleshooting sortino issues,' without clear boundaries on when it should or should not be invoked. This can cause over-selection of the skill in loosely related finance contexts, increasing the chance of irrelevant or misleading guidance being surfaced, though the skill appears to be a static reference wrapper rather than an active code-execution tool.

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The script advertises itself as a Sortino reference tool, but the body contains largely generic finance boilerplate and even references unrelated metrics such as Sharpe. This creates a trust and integrity problem: users may rely on the tool for domain-specific financial guidance and receive misleading or incorrect information, which can lead to bad decisions or compliance mistakes.

Intent-Code Divergence

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The inline documentation claims the script is a Sortino reference tool, but the implementation does not substantively cover Sortino. This mismatch is dangerous because users and downstream agents may trust the metadata and invoke the skill in finance contexts where precise, topic-specific guidance is expected.
