Summary
Malicious code in mobicommn (npm)
Details
The tarball contains just index.html and package.json (main: index.html). index.html mimics a Cloudflare Turnstile challenge and, on the Turnstile callback, reconstructs a destination URL from a rotated obfuscated string array and calls window.location.replace to redirect. There are no preinstall/install/postinstall/prepare scripts, and Node does not execute HTML on require, so the redirect does not fire on npm install or on import of the package. The shipped artifact is only reachable if the HTML file is loaded in a browser, which is not a normal consumer path for an npm dependency.

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.

No blocking static signals were detected.
