OKX Exchange WebSocket Skill

Security checks for vulnerabilities and agentic risk

Overview

This skill gives explicit instructions for subscribing to public OKX market-data WebSocket feeds and writing the received data to a local file, with no evidence of hidden credential use, trading, or destructive behavior.

Before installing, confirm you are comfortable with a running OKX public market-data subscription writing NDJSON files under the chosen sink path, and stop the subscription when finished to limit disk growth. Do not adapt this skill for private OKX authentication or trading workflows without a separate review.

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

Finding

The example workflow directs the user to start a subscription with --sink file:$HOME/.uxc/subscriptions/okx-btcusdt-ticker.ndjson, which causes ongoing file writes. While prerequisites mention a writable sink path, the markdown does not clearly warn that market data will be persisted locally or advise the user to review the destination and retention implications.
