Description

The npm package 'cvmbxcjiasdg' versions 1.0.0 and 1.0.1 contains malicious code that serves a fake Cloudflare Turnstile challenge via an index.html file. This HTML page uses obfuscated JavaScript to redirect users' browsers to a constructed URL, forwarding query parameters. The package does not execute code during npm install or require, indicating it is designed to abuse the npm registry as a static host for phishing or redirect lures rather than directly attacking developers. Any system running this package should be considered fully compromised, with immediate secret and key rotation recommended.

Impact

The package's malicious payload executes only in a browser rendering the index.html file, redirecting users to potentially malicious URLs with forwarded query parameters. Although npm install and require do not trigger code execution, the presence of this package on a system indicates a high risk of compromise. The GHSA-malware advisory states that any computer with this package installed or running should be considered fully compromised, implying potential unauthorized access or control. Secrets and keys stored on the compromised system should be rotated immediately. Removing the package alone may not eliminate all malicious software resulting from its installation.

Defensive guidance

The package should be removed immediately from any affected systems. All secrets and keys stored on the compromised computer must be rotated immediately from a separate, trusted machine. Because the package does not execute code during npm install or require, the primary risk is from browser-based redirection when rendering the index.html file. Users and administrators should avoid using or installing this package. Monitor for any signs of compromise and consider a full system audit due to the high risk of full system compromise.
