The beacon body carries only what an ordinary HTTP GET reveals (source IP, User-Agent); no environment variables, filesystem contents, or credentials are read or transmitted, and no code is fetched or executed. The destination is the canarytokens.com research service rather than attacker-controlled infrastructure. Installing this package discloses the fact and source of the install to whoever configured the canary token, and executes network I/O at install and import time without opt-out.\n\n## Source: kam193 (cce3c8791da7093bb0d6aaf8b79f49e5cbbcc4114f075f60121fc99b31c74e09)\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.
