unitel4npm
Advisory published Updated
unitel4 is a confirmed malicious npm package (MAL-2026-13838) that typosquats a legitimate package to trick installs (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in unitel4 (npm)
What this malware does
Package contains only package.json and index.html, with main pointing at index.html. The HTML impersonates a Cloudflare 'Just a moment...' interstitial; its Turnstile callback runs obfuscated JavaScript that constructs a URL ending in a '.club/' domain, appends the current query string, and calls window.location.replace to redirect the browser. There are no preinstall/install/postinstall/prepare lifecycle hooks, and an HTML file cannot be executed via require()/import, so installing or loading this package in a Node.js build environment does not execute the redirect. The payload only fires when the HTML is served to and rendered by an end-user browser, indicating registry abuse to host a phishing/cloaking landing page rather than a supply-chain attack against developers who install the package.
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.

TyposquatFind it
Search your lockfiles and build artifacts for unitel4 (version 1.0.0).
If you installed it — respond
unitel4 is a typosquat — you almost certainly intended a legitimately-named package. Remove unitel4, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.
Did it already run?
If unitel4 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 unitel4-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
