Description

The npm package @uh-platform/domain-widget@100.0.0 is a malicious package designed to perform out-of-band code execution during installation. It contains a preinstall script that executes code to send a DNS and HTTP request to an attacker-controlled domain, disclosing the installer's IP address and host information. This package mimics a private internal package namespace with an inflated version number and minimal metadata to facilitate dependency confusion attacks.

Impact

Installation of this package results in out-of-band code execution on the build machine via the preinstall script. This leads to leakage of the installer's IP address and host presence to an attacker-controlled server. The malicious code executes automatically during npm install, potentially compromising build environments that resolve this package due to dependency confusion.

Defensive guidance

Users should avoid installing the @uh-platform/domain-widget package version 100.0.0. Verify internal package namespaces and ensure private packages are not shadowed by malicious public packages. Implement strict package resolution policies to prevent dependency confusion. Monitor package sources and avoid installing untrusted or suspicious packages.

Summary

The @uh-platform/domain-widget package at version 100.0.0 is a scoped placeholder with no legitimate functionality but includes a preinstall script that executes 'node index.js'. This script uses exec() to invoke curl targeting a hardcoded Burp Collaborator subdomain (http://pa33pg1od9cr4ffnrzec8864jvpmdd12.oastify.com/). When installed, this causes the build machine to make DNS and HTTP requests to the attacker-controlled endpoint, leaking the installer's IP and confirming remote code execution during the npm install process. The package's characteristics—empty author, generic description, preinstall-only payload, and high version number—indicate a dependency confusion attack aimed at shadowing a private package within the @uh-platform namespace.
