During import, the package automatically downloads and executes code that first acts as an infostealer and then starts code acting as a RAT. It connects with a hardcoded C2 server and waits for commands, supporting e.g. executing remote commands, exfiltrating files, recording the screen, executing GUI actions through PyAutoGUI.
