## Source: amazon-inspector (ad998d7ff924f18f57116d8dd586342fd060d8fb1459d94c0a911589bc2e3686)
The package's module polls a hardcoded Telegram bot (api.telegram.org, bot id 8871201315) for commands scoped to a specific chat and topic. On matching messages it downloads a video and forces fullscreen playback while blocking keyboard and mouse input (via keyboard and pynput hooks), kills explorer.exe, and for the /YoutubeCD variant executes `shutdown /s /t 0 /f` to unconditionally power off the host. The bot token, chat id, topic id, and staging directory components are stored as base64 literals decoded at runtime by a helper function; the staging directory is placed at %APPDATA%\Microsoft\Crypto\RSA\tools to mimic the legitimate Windows RSA key-storage path. At import time the module silently pip-installs undeclared runtime dependencies (requests, keyboard, pynput, psutil) using CREATE_NO_WINDOW to hide the console, then downloads yt-dlp.exe and deno.exe from the mutable `releases/latest` GitHub URLs with no hash verification into the disguised staging path and executes them as part of the remotely driven command chain. pyproject metadata is a placeholder (`Your Name`, no email, homepage, or repository), consistent with a throwaway anonymously published package.

The package hides code for exfiltrating files, recordings from the webcam, screenshots, keylogging.
