Security audit

Portfolio Watcher

Security checks for vulnerabilities and agentic risk

Overview

This portfolio-tracking skill is coherent and not malicious, but it asks for sensitive holdings and cost-basis details without clear privacy, storage, or alerting controls.

Review this skill carefully before installing. It does not show malicious behavior, but users should avoid entering detailed holdings or cost-basis information unless they understand where that data is stored, how alerts are maintained, and how to review or delete saved portfolio data.

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
Vulnerability Patterns
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The trigger phrase "stock price" is broad enough to match ordinary finance-related conversation that may not be an intentional invocation of this skill. That can cause accidental activation in contexts where a user is merely discussing markets, increasing the chance of unintended processing of portfolio-related data or confusing skill routing.

Vague Triggers

Category

Confidence
94% confidence
Finding

The trigger phrase "crypto price" is similarly generic and likely to collide with common user requests about cryptocurrency markets. In a conversational assistant, such broad matching can invoke the skill unintentionally, exposing or soliciting sensitive holdings information without clear user awareness.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The skill encourages users to provide holdings, share counts, and purchase prices, but it does not clearly warn that this financial data will be stored or processed. Because portfolio composition and cost basis are sensitive personal financial information, lack of upfront disclosure can lead users to reveal data without informed consent or understanding of retention and privacy implications.
