Summary
Malicious code in ml-shared (PyPI)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (89a726ddb6cfd4ce7da05b1b8c75e896e38789aa418c71d4db76f499b5727cb3)

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_*, GITHUBTOKEN, NPMTOKEN, 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.
