Security audit

Investment Analyst

Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed investment-analysis guidance skill with no executable code, persistence, credential access, or hidden behavior, though users should treat its financial recommendations cautiously.

Install only if you want a Portuguese-language investment analysis helper. Do not treat its outputs as personalized regulated financial, tax, or legal advice, and avoid sharing unnecessary personal financial details unless needed for the analysis.

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
Findings (3)

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
79% confidence
Finding

The manifest description and the entire skill documentation are written in Portuguese, and the response format section does not indicate that users may choose another language. Under the language/locale policy, a skill should not implicitly force a language unless the constraint is justified or optional.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The description and usage text are broad enough to trigger on many generic investment-related requests without clearly stating when the skill should or should not be invoked. In an agent-routing context, this can cause over-selection of the skill, leading to inappropriate financial guidance, unnecessary tool use, or the model bypassing safer/general handlers for ambiguous requests.
