Description
The npm package 'twcvhjlksdmx' versions 1.0.0 and 1.0.1 contains malicious code embedded in an index.html file that impersonates a Cloudflare interstitial and redirects users who open the HTML file in a browser. The package.json does not execute code during installation or require, so the malicious redirect only triggers if the HTML file is manually opened in a browser. Installation of this package can lead to full system compromise, requiring immediate secret and key rotation and package removal.
