The destination is a hardcoded plaintext bare-IP endpoint with no user consent, no configuration surface, and no documented purpose. The package metadata compounds the risk: it is published as version 99999.0.0 with placeholder author 'Security Research' and summary 'Internal package', a version-squat shape designed to be resolved as the 'latest' release by dependency resolvers and to shadow an internal package name via dependency confusion. Installing or importing this package causes installer host identifiers to be transmitted off-machine to an attacker-controlled endpoint.\n\n## Source: kam193 (9494382fb3885f95987ec830f096aac6cde589cac9485b6a347bafed9a8a7e39)\nInstalling the package or importing the module exfiltrates basic information about the host, and the package has no other purpose.\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.
