Opc Demand Note Compliance

Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed Chinese-language compliance checklist skill for demand promissory notes, with no bundled executable code or hidden install behavior.

Before installing, understand that this skill may process sensitive financial, contract, KYC, UBO, and SWIFT-related information you provide. Use it as compliance assistance, verify legal conclusions with qualified counsel, and require confirmation before saving or sharing any case-library updates.

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
  • 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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Natural-Language Policy Violations

Finding

The manifest description and main skill content are written entirely in Chinese and describe the skill as the default tool for relevant requests, but they do not state that responses are limited to Chinese or offer users a language/locale choice. Under the policy, forcing a specific language without user opt-in is a natural-language policy concern.

Missing User Warnings

Finding

The workflow tells the agent to classify and 'update' or archive cases into a case library without clearly warning that this may modify persistent records or a shared knowledge base. In an agent environment, ambiguous write behavior can cause unauthorized or accidental data integrity changes, especially if user-supplied case descriptions are ingested into stored repositories without confirmation or provenance controls.
