Binance Trading Signal

Security checks for vulnerabilities and agentic risk

Overview

This is a simple documented skill for retrieving public on-chain trading-signal data, with financial-risk caveats users should keep in mind before relying on it.

Install only if you want an agent to fetch and summarize speculative on-chain trading-signal data from Binance Web3. Treat outputs as informational and time-sensitive, not financial advice, and do not rely on the skill alone for trading decisions.

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

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The skill's invocation guidance is broad enough to trigger on generic investment-opportunity queries, which can cause the agent to surface trading signals outside a narrowly scoped user request. In a financial context, overbroad routing increases the chance of unsolicited or overly action-oriented investment content being presented as relevant, which can mislead users or bypass more appropriate safety and suitability checks.

Missing User Warnings

Not specified by scanner
Confidence
96% confidence
Finding

The skill presents trading signals and opportunity-discovery use cases without a clear warning that the data is informational, speculative, and highly time-sensitive. In financial workflows, this omission can cause users to overtrust the output as actionable advice, especially when metrics like max gain and smartMoneyCount imply reliability.
