Security checks for vulnerabilities and agentic risk

Overview

This is an instruction-only skill for using a relay messaging service, and its network, credential, and messaging behaviors are disclosed and operator-controlled.

Install only if you intend to use Voidly relay services. Before registering identities, sending messages, posting to channels, invoking RPC, or using memory methods, confirm the exact client, recipient, content, encryption path, and where credentials will be stored. Do not paste API keys, private keys, seed phrases, or exported credentials into prompts or public files.

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
