bitfence

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed, read-only token risk-check helper that sends limited token data to Bitfence with user consent for paid checks.

Before installing, understand that Bitfence checks are paid x402 requests using USDC on Base mainnet. Use contextual analysis only when you are comfortable sharing position size and total portfolio size in USD with Bitfence; the skill does not ask to sign trades or move funds.

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
