Description

The npm package 'ap3-components-ui' version 9.999.0 contains malicious code that executes a preinstall hook to collect sensitive installer environment data and exfiltrates it via DNS queries to an attacker-controlled domain. The package is a dependency-confusion squat designed to override legitimate internal packages. Installation of this package can lead to full system compromise, requiring immediate secret and key rotation and package removal.

Impact

Any system with this package installed or running should be considered fully compromised. The attacker may have obtained sensitive environment information and potentially full control of the system. All secrets and keys stored on the compromised system should be rotated immediately from a separate, trusted machine. Removing the package alone does not guarantee removal of all malicious artifacts or backdoors.

Defensive guidance

Remove the 'ap3-components-ui' package version 9.999.0 immediately. Rotate all secrets and keys that were stored or used on the compromised system from a different, secure computer. Because full system compromise is possible, conduct a thorough investigation and remediation of the affected host.

Summary

The 'ap3-components-ui' npm package at version 9.999.0 includes a preinstall script that collects installer-side identifiers such as hostname, current working directory, username, and public IP address by querying ifconfig.me. This data is hex-encoded and exfiltrated as DNS subdomain queries to a malicious Interactsh collector domain controlled by an attacker. The package contains no legitimate library code and is structured as a dependency-confusion attack to supersede internal package versions. The presence of this package indicates a high risk of full system compromise.
