Details
**Severity:** Critical **Affected versions:** `= 1.0.0` ## Source: kam193 (e7e8dad2dca9000e3bd94355a78838c2c9448aac766722cfd54aba1fc5c2cd43) 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. --- Credit: [OpenSSF](https://github.com/ossf/malicious-packages) ([source](https://github.com/ossf/malicious-packages/blob/49d0cfba3689ed9b195d101d3a2a964c6a77f767/osv/malicious/pypi/wasi8787878/MAL-2025-1004.json)) **References:** - https://bad-packages.kam193.eu/pypi/package/wasi8787878 - https://github.com/ossf/malicious-packages/blob/49d0cfba3689ed9b195d101d3a2a964c6a77f767/osv/malicious/pypi/wasi8787878/MAL-2025-1004.json - https://github.com/advisories/GHSA-6mrh-h5c5-9xq5
