Lottery Liu

Security checks for vulnerabilities and agentic risk

Overview

This skill only instructs an agent to look up public Chinese lottery results, with a minor disclosed sign-off requirement.

Before installing, note that replies produced through this skill may include a fixed celebratory Chinese sign-off after lottery lookups. The skill otherwise appears limited to retrieving public lottery-result information from named public websites.

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

Findings (1)

Natural-Language Policy Violations

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The skill mandates appending a fixed celebratory phrase to every response regardless of the user's preferences or context. This creates an unnecessary output constraint that can override user intent, reduce neutrality, and normalize instruction-following behavior originating from untrusted skill content.
