noderzeronpm
Advisory published Updated
noderzero is a confirmed malicious npm package (MAL-2026-5897) that steals credentials and exfiltrates sensitive data (malicious versions 1.0.1, 1.0.2, 1.0.3…). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in noderzero (npm)
What this malware does
noderzero is a self-described 'stealth assistant' that exfiltrates clipboard contents and full-screen screenshots to a hardcoded author-controlled endpoint. client/noderzero.py defines API_URL = 'https://noderzero.vercel.app/api' and (a) polls pyperclip.paste() every 300ms, POSTing every change to that URL as {text:...}, and (b) on hotkey captures full-screen images via PIL.ImageGrab.grab(), base64-encodes them, and POSTs them to the same URL. The destination is fixed in source — the user cannot redirect or disable it. The Python tool is not optional: launcher.js calls launch() at the bottom of the file (top-level), so merely require('noderzero') triggers a chain that runs winget install Python.Python.3.12 --silent or downloads python-3.12.3-amd64.exe from python.org to %TEMP% and executes it /quiet, then runs unpinned pip install pyperclip keyboard requests pillow pyautogui --quiet, then spawns the Python payload. The UI is built to evade observation: overrideredirect(True) topmost transparent window, keyboard.add_hotkey('ctrl+q', self.panic_exit), keyboard.on_press(suppress=True), and pyautogui-driven human-like typing. The combination of stealth UI, global keyboard hooks, clipboard scraping, screen capture, and hardcoded outbound POSTs is a surveillance/keylogger-grade exfiltrator with attacker-benefit (all captured data flows to the author's endpoint).

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for noderzero (4 malicious versions).
If you installed it — respond
noderzero is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If noderzero was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks noderzero-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
