Chance Fc3d Predictor

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed FC3D lottery-analysis reference with no bundled execution, storage, network access, credentials, or persistence.

Before installing, treat this as gambling-related educational content only. It should not be relied on to predict winning numbers, and users should keep strict budget limits and avoid using it for minors, online lottery purchasing, or paid prediction claims.

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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
87% confidence
Finding

The trigger list includes broad terms such as 'lottery analysis' and 'number prediction' alongside priority Chinese keywords, which can cause the skill to activate for generic gambling-related requests outside the narrowly described FC3D scope. In a gambling context, overbroad routing increases the chance of unsolicited betting advice, policy bypass through ambiguous prompts, and accidental invocation in contexts where stronger safeguards should apply.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
82% confidence
Finding

The phrase "中文触发词（优先）" explicitly gives priority to Chinese-language triggers. This indicates a language-selection policy embedded in natural language rather than letting the user choose their preferred language.
