Security checks for vulnerabilities and agentic risk

Overview

This skill is a Chinese-language freelance opportunity helper that uses disclosed web requests to scan job platforms and does not show hidden execution, persistence, or destructive behavior.

Before installing, expect the agent to make web requests to freelance and content platforms and to use any skill/profile details you put in the local HUSTLE.md file for recommendations. Review generated proposals before sending them, as the skill itself also advises.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill's title, description, commands, configuration guidance, and examples are entirely in Chinese, with no indication that other languages are supported or that Chinese is a necessary regional constraint. Under the policy, forcing a specific language without user opt-in is a natural-language policy violation unless the locale limitation is explicitly justified.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The skill explicitly advertises automatic scanning of multiple third-party platforms but does not warn users that prompts, search terms, IP address, and possibly profile-related context may be transmitted to external services. In a skill that encourages repeated web/API access, omission of a privacy and data-transmission notice can mislead users into sharing data they did not intend to send off-platform.

External Transmission

Medium
Category
Data Exfiltration
Confidence
91% confidence
Finding

The example command issues an outbound POST request to an external API endpoint, which creates a real data-transmission boundary and can expose user-derived query context, metadata, and network identifiers to a third party. Because the skill is designed to automate scanning, this behavior could occur repeatedly and without adequate user awareness if integrated directly into agent actions.
