Preflyte

Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed read-only DeFi market-data skill that uses PreFlyte APIs and does not install code, access wallets, or request transaction authority.

Install only if you are comfortable sending DeFi query details, such as assets, chains, position sizes, strategies, and an API key, to PreFlyte. Treat results as decision support rather than guarantees, and keep any MPP/pay-per-request usage behind explicit spending controls.

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
