Which versions of nodeberlin are malicious?

The following npm versions of nodeberlin are flagged malicious: 1.0.7. Treat any of these as compromised.

How do I remediate nodeberlin if I installed it?

nodeberlin 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.

I already installed nodeberlin — how do I know if it already compromised me?

If nodeberlin 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.

Is nodeberlin part of a known attack campaign?

Yes — nodeberlin is associated with the IN-MAL-2026-018387 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find nodeberlin across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for nodeberlin (version 1.0.7).

What this malware does

The CLI polls the system clipboard every 300ms and captures full-desktop or user-snipped screen regions, then POSTs the JSON text and base64-encoded JPEG image data to a hardcoded author-controlled endpoint at https://tokyoap.vercel.app/api (API_URL). The destination is not caller-configurable and the package accepts no user-supplied API key, so all installers' clipboard contents and screenshots are routed through the author's proxy. On first run the bin auto-downloads the Python.org installer and pip-installs keyboard, pyautogui, pillow, pyperclip, and requests to support global hotkeys, screen capture, and the relay; a panic-exit hotkey and stealth overlay accompany the capture path. Clipboard buffers and screenshots routinely contain credentials, private messages, and other sensitive material; funnelling them through a hardcoded third-party endpoint materially harms the installer.
