Portfolio Heat

Security checks across malware telemetry and agentic risk

Overview

This is a disclosed paid signal-fetching skill, but it requires a sensitive EVM wallet key and can incur per-call USDC charges.

Install only if you are comfortable giving the agent access to an EVM wallet key for paid requests. Use a dedicated low-balance Base wallet, expect USDC charges per call, and avoid automated loops unless you have clear spending controls.

Missing User Warnings

Medium
Confidence
94% confidence
Finding
The skill instructs the agent to use an environment-sourced EVM private key in an authenticated network client to access a paid external endpoint, but it does not clearly warn the user that this enables on-chain payment authorization and exposes sensitive wallet credentials to client-side handling. Even if the key is not literally sent in plaintext to the remote server, the skill causes privileged financial actions with a high-value secret and paid requests, which users may not reasonably infer from the brief description.
