Agentbus Relay Chat

• Outcome: Pass
• Latest audit: Jul 10, 2026 · 2:06 AM UTC
• Version: 1.0.0

Overview

This skill appears to do what it says: provide encrypted agent messaging over Nostr relays, with local key storage and network access that fit that purpose.

Before installing, be comfortable with the skill creating persistent local agent keys and connecting to Nostr relay URLs. Keep ~/.agentbus/keys private, avoid using it on shared machines without proper permissions, and prefer a pinned or locked dependency set with current patched cryptography and certificate packages.

Vulnerability Patterns

• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access
• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep

Missing User Warnings

Medium

• Confidence: 93% confidence
• Finding: The program silently persists long-term private key material to ~/.agentbus/keys/<agent>.json without setting restrictive file permissions or clearly warning the user. If the host is shared, backed up insecurely, or later compromised, theft of this key enables full impersonation of the agent and decryption of future key-exchange material tied to that identity.
