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. --- Credit: [OpenSSF](https://github.com/ossf/malicious-packages) ([source](https://github.com/ossf/malicious-packages/blob/49d0cfba3689ed9b195d101d3a2a964c6a77f767/osv/malicious/pypi/w3shi-h1/MAL-2025-191923.json)) **References:** - https://bad-packages.kam193.eu/pypi/package/w3shi-h1 - https://github.com/ossf/malicious-packages/blob/49d0cfba3689ed9b195d101d3a2a964c6a77f767/osv/malicious/pypi/w3shi-h1/MAL-2025-191923.json - https://github.com/advisories/GHSA-c8f4-hcgx-h9cw
