Security audit

X402hub

Security checks across malware telemetry and agentic risk

Overview

This skill appears purpose-aligned for x402hub marketplace use, but its relay helper reportedly sends an auth token over plaintext TCP, which should be reviewed before use.

Install only if you are comfortable with x402hub network calls and credentialed marketplace actions. Use a dedicated, limited-privilege token or wallet, avoid sending sensitive relay messages until TLS or another protected transport is confirmed, and rotate any token used with the plaintext relay helper.

Vague Triggers

Medium
Confidence
80% confidence
Finding
The skill description uses broad trigger terms like 'bounty', 'relay messaging', and 'USDC earning', which can cause the skill to activate in contexts broader than intended. Unintended invocation is risky here because the skill can initiate external network actions, registration flows, and agent-to-agent communications with real credentials and wallet-linked identity.

Missing User Warnings

Medium
Confidence
96% confidence
Finding
The script sends an authentication token in a HELLO message over Node's raw net TCP socket, with no TLS, certificate validation, or other transport protection visible in the code. That exposes the relay token and message metadata/body to interception or modification by any network observer or active man-in-the-middle, which is especially dangerous because this skill is explicitly designed for agent-to-agent communication and credentialed marketplace operations.
