Buy Sovereign Domain (Handshake DNS)

Security checks for vulnerabilities and agentic risk

Overview

This skill needs review because it prepares Ethereum mainnet domain-registration transactions while leaving the exact contract details and safety rules in an external file outside the package.

Review this before installing. The skill may be intended for legitimate domain registration, but users should not rely on it unless the exact contract addresses, ABIs, transaction values, chain ID, and per-transaction confirmation rules are bundled or otherwise integrity-pinned and clearly shown before signing.

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
