Description

The npm package @mntv-analysis/ui-components version 50.1.1 is a malicious package published by the user 'conx3993' as part of a dependency confusion attack. It masquerades as an internal package and executes a preinstall script that sends an HTTPS request to an attacker-controlled server, leaking the victim's public IP address and signaling successful installation. The package contains no legitimate UI component code and serves solely as a tracking beacon.

Impact

Installation of this package leaks the victim's public IP address and confirms that the attacker's package was resolved and installed in the victim's build environment. According to the source, any system with this package installed or running should be considered fully compromised, with potential exposure of all secrets and keys stored on that system. Removal of the package alone may not eliminate all malicious software resulting from the compromise.

Defensive guidance

Immediate removal of the @mntv-analysis/ui-components@50.1.1 package is recommended. All secrets and keys stored on the affected system should be rotated from a separate, trusted environment. Organizations should audit their package resolution configurations to prevent dependency confusion attacks, ensuring internal packages are resolved correctly and not overridden by malicious public packages. Monitor for any signs of further compromise as removal of the package may not fully remediate the infection.

Summary

@mntv-analysis/ui-components@50.1.1 is a hollow npm package designed for dependency confusion attacks. It uses a high version number and a scoped name to override legitimate internal packages in misconfigured environments. Upon installation, a preinstall hook runs a script that sends an HTTPS GET request to realwbx.com with a hardcoded Authorization token unique to this package. This request reveals the victim's public egress IP and confirms the package's installation, allowing the attacker to identify and track compromised environments. The package contains no functional UI components and is solely intended to collect installation telemetry.
