Summary
Malicious code in mnzjgxciwadk (npm)
Details
The package contains a single file, index.html, which is also declared as the package main. The HTML presents a Cloudflare Turnstile-styled challenge page and, on completion, executes obfuscator.io-style JavaScript that constructs a URL against a *.olive.club host and navigates window.location to it, forwarding query-string parameters. There are no lifecycle scripts (preinstall/install/postinstall/prepare) and no JavaScript module entrypoint, so npm install and require()/import of this package do not execute the redirect code. The harm surface is a browser user who opens the HTML file, not a developer or build system that installs the package. This is registry abuse — hosting a phishing/redirect landing page inside an npm package — rather than a supply-chain attack against installers.

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.
