coderzeronpm
coderzero is a confirmed malicious npm package (MAL-2026-5610) that steals credentials and exfiltrates sensitive data (malicious versions 1.0.0, 1.0.1, 1.0.2…). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in coderzero (npm)
What this malware does
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.

Detection & response playbook
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for coderzero (5 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging coderzero across your stack and pipelines.
If you installed it — respond
coderzero 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 coderzero was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks coderzero before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

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