MAL-2026-11202 Malicious code in ml-shared (PyPI)

setup.py defines a function named analytics() that collects the installer's hostname, username, current working directory, and the entire process environment (dict(os.environ)) and POSTs it as JSON to https://request-forwarder.a-d-a-m.workers.dev/. The routine fires both at module top-level (executed during pip's build/install of the sdist) and via a PostInstallCommand hooked into cmdclass={'install':…}, so it runs on pip install without user interaction. On CI/build agents the bulk os.environ dump routinely contains credentials such as AWS_*, GITHUB_TOKEN, NPM_TOKEN, PYPI_TOKEN, and other secret-shaped variables. The destination is an anonymous Cloudflare Workers subdomain unrelated to any declared publisher, the function is named analytics as a cover, and code lines are padded with trailing whitespace consistent with evasion of casual review.

During installation, package exfiltrates basic info and all environmental variables.

Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Campaign: 2026-07-ml-shared

Reasons (based on the campaign):

• exfiltration-env-variables

• The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.
