Its setup.cfg declares a dependency_links entry pointing at a webhook.site UUID endpoint (https://webhook.site/56557fe9-5bcf-4f26-bed7-38f772525011/pypi/aliga-raison). webhook.site is a generic HTTP-callback inspector commonly used to receive beacon traffic. Modern pip ignores dependency_links, so installer harm is minimal in practice, but the artifact's shape — trivial code, no real functionality, install metadata pointing at a request-inspector endpoint named after a PyPI package — is consistent with a reconnaissance probe testing which installers still process dependency_links. No exfiltration, RCE, credential read, or persistence mechanism is present in the package code.\n\n## Source: kam193 (168dd7abca8ed812dcfb0119eaf80a2b05b186ee37a1e0c8f98e88f884a90602)\nPackage attempts to test exploitation via legacy dependency_links configuration\n\n\n---\n\nCategory: 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.\n\n\nCampaign: GENERIC-standard-pypi-install-pentest\n\n\nReasons (based on the campaign):\n\n\n - The package contains code to exfiltrate basic data from the system, like IP or username.
