Summary
Malicious code in fghvbmniwu (npm)
Details
Package contains a single index.html declared as `main`, which is a Cloudflare-branded 'Just a moment...' clone embedding a Turnstile widget and heavily obfuscated JavaScript (obfuscator.io-style `_0x...` identifiers, shuffled string array, control-flow flattening) that assembles a redirect URL at runtime and assigns it to `window.location`, forwarding the current query string. There are no preinstall/install/postinstall/prepare lifecycle scripts, and `main` points to HTML that Node cannot require or import, so installing or requiring this package does not execute code on a developer machine or build system. The behavior only affects a browser that loads this file via a CDN mirror (unpkg/jsdelivr), consistent with abuse of the npm registry as free CDN hosting for a phishing/redirect landing page rather than an attack on the installer.

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.
