Do not edit below this line.=-_\n\n## Source: amazon-inspector (177a91975e11b9b3afbc5089dfc7e4c4fdae1cb05f8307f397956c675533f0d8)\npypi package zagents-message-bus is published at an implausibly inflated version (99.99.100) under an internal-sounding name, consistent with a dependency-confusion resolution-override attempt against a private package of the same name. The shipped main.py defines CALLBACK_URL = \"https://webhook.site/b961eb5e-fabc-43a5-83a3-d1509c3a558e\" and performs an HTTP GET to that URL with a diagnostic-error query parameter when main() is invoked. The webhook.site endpoint is an anonymous third-party request-logging service typical of dependency-confusion canaries and reconnaissance beacons. The package has no install-time hook (no setup.py side effects, no build-backend network I/O) and the beacon does not fire on bare import — the __init__ re-exports symbols that do not exist in main.py, so `import zagents_message_bus` raises ImportError before the GET runs. The beacon therefore only fires if a consumer explicitly calls main(). No credential reads, filesystem writes outside the package, or code execution of fetched content are present.\n\n## Source: kam193 (0d1891d5d76adad51e120baa41752f0cc878b243eb400e7a12aba1616d31d1f7)\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.
