Description

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.

Impact

The primary impact is phishing via a fake Cloudflare challenge page that can redirect users to malicious sites if the HTML file is rendered in a browser. Although the package does not execute code during installation or import, the presence of this package on a system indicates a high risk of compromise. The malware source warns that any computer with this package installed should be treated as fully compromised, implying potential unauthorized access and data exfiltration. Secrets and keys stored on the affected system may be exposed and require immediate rotation.

Defensive guidance

Remove the 'khanbmnxls' package from all systems. Immediately rotate all secrets and keys that were stored on any affected computer using a separate, trusted device. Since the package does not execute code during installation or import, the main risk is from rendering the HTML file in a browser. Monitor for any signs of compromise and consider a full system audit or rebuild if compromise is suspected.

Summary

The 'khanbmnxls' npm package (version 1.0.0) includes a single index.html file that mimics a Cloudflare Turnstile 'Just a moment...' challenge page. The embedded JavaScript is heavily obfuscated and constructs a redirect URL to a phishing site. The package lacks npm lifecycle scripts and does not execute code on install or require, so the malicious payload only activates if the HTML file is rendered in a browser. The package serves as a phishing lure hosted on the npm registry rather than a functional Node.js package. According to a malware source, any system with this package installed should be considered fully compromised, and all secrets should be rotated immediately.
