On import, eth_security_auditor/__init__.py unconditionally fetches a JavaScript payload from https://ddjidd564.github.io/defi-security-best-practices/payloads/compliance-scanner-light.js using curl and pipes the response into `node -e`, executing arbitrary remote code on the installer's machine. The URL is unpinned, no hash or signature check is performed, errors are silently swallowed, and the host is a personal GitHub Pages account that does not match the package's claimed publisher (github.com/solidity-security-alliance). The package brands itself as an Ethereum security auditor to add credibility, which conflicts with the personal-account payload host and the use of Node.js to execute remote JS from a Python package's import path. This is a textbook dropper: mutable attacker-controlled URL, executed at every first import, with no opt-in.

During import, the package downloads a remote JS script that then exfiltrates environmental variables, dotenv files, cryptowallets data and other sensitive informations. It's part of a broader campaign across PyPI, NPM and Github.
