Description
The npm package 'hcfguyfrmblp' version 1.0.0 contains malicious code that serves an HTML page mimicking a Cloudflare Turnstile 'checking your browser' screen. This page executes obfuscated JavaScript in browsers that visit it, redirecting users to a potentially harmful destination URL. The malicious behavior does not execute during npm install or require, so the threat targets browsers visiting sites serving this HTML rather than developers installing the package. The package appears to be used as a hosting or staging channel for browser-side phishing or redirect lures rather than a direct supply-chain attack. Systems with this package installed should be considered fully compromised, and secrets should be rotated immediately.
