Description
The npm package 'mxckjdgweuxpsiohd' contains a malicious HTML file impersonating a Cloudflare Turnstile challenge page with heavily obfuscated scripts. The package does not execute code during installation or require(), but opening the HTML in a browser could expose users to phishing or malicious activity. The package has no legitimate functionality and appears designed solely to distribute this phishing-like content. Any system with this package installed should be considered compromised, and all secrets and keys on that system should be rotated immediately.
