The npm package 'khanbmnxls' version 1.0.0 contains a malicious HTML file that impersonates a Cloudflare Turnstile challenge page with heavily obfuscated JavaScript designed to redirect users to a phishing site. The package does not execute code during installation or import, limiting the attack surface to browsers that directly render the HTML file. Despite this, the package is considered malicious and poses a significant risk if the HTML is accessed. Removal of the package is recommended, but full system compromise is possible if the package was executed, necessitating secret and key rotation.
