Summary: Malicious code in cosmos-cuda (PyPI)

Details: Source: amazon-inspector (c1a96e5776ec64356f639738134c95a2f33233a4275d2d0ddd6b174c297c64ee) The sdist-only package cosmos-cuda 9999.0.0 executes a beacon function `_beacon('build')` from setup.py during sdist build/install and `_beacon('import')` from cosmos_cuda/__init__.py at import. Both code paths collect the installer's hostname, current username, and current working directory, then transmit them to the hardcoded external host `oob.asyncrun.in` via a DNS lookup of a crafted FQDN (socket.getaddrinfo) and via an HTTPS/HTTP GET request (urllib.request.urlopen). The package ships only as an sdist and uses version 9999.0.0 so that pip's highest-version resolution selects it when a name collision exists against an internal package resolved through `--extra-index-url`, forcing setup.py execution during install and producing arbitrary code execution and exfiltration on installers whose environment resolves the name. Source: kam193 (bd8651969d2a82aa0c96bae9bce8bffaa3053dc4093fcafc614f7cda24b19542) Installing the package or importing the module exfiltrates basic information about the host, and the package has no other purpose. Category: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research & co, with clearly low-harm possibilities. Campaign: GENERIC-standard-pypi-install-pentest Reasons (based on the campaign): - The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk. - The package overrides the install command in setup.py to execute malicious code during installation.
