## Overview

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

## Source: amazon-inspector (e4271f738e49ead6113a249ca949232cad9664db210319a097b56385b1942970)
The package advertises itself as an HTTP speed-up library, but on import it archives the user's Monero wallet directory (C:\Users\<user>\Documents\Monero on Windows, /home/<user>/Monero on Linux) and uploads the archive to a hardcoded Telegram bot via api.telegram.org/bot<token>/sendDocument (chat_id -5044692933). The destination bot token and wallet paths are stored as base64 blobs (constants TK, XMR_WIN, XMR_LINUX) and decoded at runtime to conceal the exfiltration target. The exfil routine is invoked at module top level, so any `import btcflip` (which loads the inner `kotoraka` module) triggers wallet theft. The code also terminates feather/monero processes to release file locks before archiving. The stated purpose of the package is unrelated to Monero wallets and is a cover story for wallet theft.

During import, the package exfiltrates cryptocurrency wallet files.
