Halo

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed A-share stock analysis workflow, with no bundled executable code or hidden persistence found.

Before installing, understand that this skill is meant to run local Python scripts and fetch market/news data to produce investment-style reports. Only use it in a workspace where the referenced scripts are known and trusted, and treat the generated report as informational rather than financial advice.

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

Finding

The trigger is defined broadly enough that ordinary user requests for A-share stock analysis could invoke this skill automatically, even when the user did not explicitly request /halo. This increases the chance of unintended activation, surprising execution of local scripts, and unnecessary access to financial/news data sources in contexts where a simpler response would have sufficed.

Vague Triggers

Medium

Confidence
96% confidence
Finding

The markdown trigger text says any request to analyze an A-share stock should activate the skill, which is an ambiguous auto-trigger condition. In practice, that can cause overbroad routing of normal conversation into a workflow that executes multiple Python scripts and fetches external data, creating avoidable security and safety exposure through unintended tool use.
