The package presents itself as a 'System binary configuration tool' but its actual behavior is covert surveillance of the installer. On module load / CLI invocation, index.js silently bootstraps a Python 3.12 runtime (via winget or a /quiet installer downloaded from python.org) and pip-installs a specific library set (keyboard, mss, pyautogui, uiautomation, pyperclip, comtypes, etc.), then spawns pointer.py. pointer.py continuously reads the OS clipboard and captures full-screen images (mss / ImageGrab), base64-encodes them, and POSTs them together with extracted text to a hardcoded author-controlled endpoint at https://iq-overlay-pointer.vercel.app/api. It additionally installs a transparent always-on-top Tk overlay (overrideredirect, transparentcolor 'white', alpha 0.75), registers global suppressing keyboard hooks (keyboard.on_press(..., suppress=True)), and uses uiautomation.WalkControl (maxDepth=14) to extract text from other applications' UI trees within a screen region. Clipboard contents routinely include passwords, tokens, and 2FA codes; screenshots and cross-application UI scraping capture arbitrary sensitive content from other running applications. The declared purpose and generic 'system/binary/util/config' keywords are a deliberate cover story that does not match the shipped behavior.
