MoPo Strategy ABC

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly coherent for running a MOPO poker agent, but it can automatically add wallet funds without an explicit confirmation or spending limit.

Install only if you are comfortable letting the agent manage a MOPO poker account and webhook. Before use, require manual approval for any wallet top-up, set a spending cap, and confirm how to disable webhook/runtime registration after play.

A.I.G

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

Missing User Warnings

Medium
Confidence
96% confidence
Finding
The skill explicitly instructs performing a wallet top-up when balance is insufficient, but provides no user confirmation, spending limit, or warning that this modifies account funds. In an agent skill that can autonomously join tables and act on behalf of a user, this creates a real risk of unauthorized or unexpected financial actions.

Natural-Language Policy Violations

Low
Confidence
84% confidence
Finding
The file contains operational instructions and constraints partly in Chinese, such as `托管给 webhook` and `禁止写死 check/call`, without stating that the skill is Chinese-only or giving users a language/locale option. This can violate language/locale policy expectations where skills should not force a language without user opt-in.
