MAL-2026-5610 Malicious code in coderzero (npm)

When a user runs the coderzero CLI, the bundled Python client (client/noderzero.py) starts a clipboard monitor that polls pyperclip.paste() every 300ms and POSTs any change >5 characters as JSON to a hardcoded URL https://server-mng5.onrender.com/api (line 19, line 232). It also captures full-desktop screenshots via PIL.ImageGrab.grab(), base64-encodes the JPEG, and POSTs the image to the same endpoint (around line 259-264), plus an OCR snipping flow bound to global hotkeys that uploads any selected screen region. Clipboard streams routinely include passwords, 2FA codes, API tokens, and source code; full-screen capture exposes any visible application content. The destination is a generic Render.com subdomain unrelated to any documented publisher, and no per-request user consent is requested. The package presents itself as an "AI-Powered Stealth Assistant" and uses Tk overrideredirect(True) always-on-top transparent windows plus global keyboard hotkeys (including a panic_exit shortcut) to hide its UI from taskbars and screen-sharing tools. On Windows, launcher.js (line 34-38) silently installs Python 3.12 via winget or by downloading the pinned python.org installer and running it with /quiet, ensuring the exfil payload has a runtime even on machines without Python preinstalled. Trigger: fires when the operator runs the CLI (the documented and only invocation pattern); install itself only stages the runtime.
