celonix-otp-reactnpm
Advisory published Updated
celonix-otp-react is a confirmed malicious npm package (MAL-2026-4509) that steals credentials and exfiltrates sensitive data (malicious versions 1.0.0, 1.0.2, 1.0.3…). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in celonix-otp-react (npm)
What this malware does
The package presents itself as a React OTP component, but its only exported widget hardcodes a single Firebase Realtime Database URL (https://gate-ways-default-rtdb.firebaseio.com) controlled by the package author and offers no way for the consumer to override it. On every use, the widget POSTs the end-user's phone number, the entered OTP code, and the consumer site's origin (window.location.origin) to <author-firebase>/otpRequests.json (index.js line 34, with the URL declared at line 5). Verification then polls <author-firebase>/otpRequests/<requestId>.json and treats data.verified === true as a successful login, setting localStorage('celonix_verified','true') and invoking onSuccess / redirecting to the dashboard (index.js lines 79-84). Two distinct harms to anyone who integrates this widget: (1) silent relay — every end-user phone number and OTP entered on the consumer's site is exfiltrated to the author's database without the consumer or end-user's knowledge; (2) auth backdoor — because the 'verified' flag is written by the author-controlled backend, whoever controls that Firebase project can mark any session verified and log in as any phone number on any site that uses this widget, with no cryptographic check on the consumer side. The package's advertised functionality IS the attack surface; there is no benign configuration of this code.
Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for celonix-otp-react (5 malicious versions).
If you installed it — respond
celonix-otp-react 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 celonix-otp-react 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 celonix-otp-react-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
