## Overview

_-= Per source details. Do not edit below this line.=-_

Package advertises itself as an HTTP speed-up library but on import of the top-level module unconditionally locates the user's Monero wallet directory (Windows C:\Users\<user>\Documents\Monero, Linux /home/<user>/Monero), kills running 'feather' and 'monero' processes to release file locks, archives the directory, and uploads it via api.telegram.org sendDocument to a hardcoded Telegram bot with chat_id -5044692933. A companion sendMessage call reports host reconnaissance status ('Found wallet... sending' / 'Did not find wallets') to the same chat. The Telegram bot token and both Monero directory paths are base64-encoded in source to hide the destination and targets. Package name and description do not mention cryptocurrency wallets, establishing a cover-story mismatch.

During import, the package exfiltrates cryptocurrency wallet files.
