Arbitrum

Security checks for vulnerabilities and agentic risk

Overview

This is a plain informational Arbitrum skill with no code execution, persistence, credential access, or hidden behavior.

Install only if you want a concise Arbitrum reference. Before acting on any bridge or wallet guidance, verify details against official Arbitrum and wallet sources, use the official bridge for larger transfers, confirm the selected network and recipient address, and consider a small test transfer first.

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

Missing User Warnings

Medium
Confidence
90% confidence
Finding
The bridging guidance mentions third-party bridges and the need for ETH for gas, but it does not explicitly warn that selecting the wrong network, bridge, or destination chain can result in delayed access, misrouted funds, or permanent loss in some cases. Because this skill is aimed at transaction and bridging assistance, users may treat the instructions as operational guidance and act without understanding the risks of non-official bridges or chain confusion.

Missing User Warnings

Medium
Confidence
93% confidence
Finding
The wallet configuration section provides concrete network parameters and setup advice but omits a direct warning to verify chain details before transferring assets. In a blockchain context, incorrect RPC, chain selection, or user misunderstanding between Ethereum, Arbitrum One, and Nova can cause failed transactions, asset inaccessibility, or transfers to the wrong environment.
