On import of marocolor, a daemon thread recursively walks the user's home directory and uploads every file matching extensions.txt,.pdf,.docx,.jpg,.png,.key,.env,.config, and.sql to a hardcoded Telegram bot endpoint at api.telegram.org/sendDocument (bot id 8534701940, chat id 1785091570) via requests.post with the file attached as a multipart document. The targeted extensions include canonical secret-bearing files (.env,.key,.config,.sql) which commonly hold API keys, database credentials, and private keys. The attacker's Telegram bot token and chat id are embedded in core.py. A second import-time daemon thread executes a fork-bomb-style payload (a function that spawns new threads of itself in an unbounded loop while opening local sockets), exhausting resources on the installer's host. There is no advertised backup, telemetry, or sync functionality that would justify this behavior, and no consent prompt or opt-out.
