Description

The npm package webrix-docs1 version 10.2.11 contains malicious code that executes a preinstall script during npm install. This script collects detailed system and user information from the host machine and sends it to an attacker-controlled endpoint. The package mimics a legitimate project name, suggesting a typosquatting or dependency confusion attack. There is no advertised functionality or author information, indicating it is solely designed for reconnaissance and data exfiltration.

Impact

Installing the affected version 10.2.11 of webrix-docs1 results in leakage of sensitive system and user information to an attacker-controlled endpoint. This information disclosure can aid attackers in further reconnaissance and targeted attacks against the compromised environment. There is no indication of code execution beyond the data exfiltration, and no known exploits in the wild have been reported.

Defensive guidance

Users should avoid installing the webrix-docs1 package version 10.2.11. Verify package authenticity before installation to prevent typosquatting or dependency confusion attacks. Monitor package sources and use trusted registries.

Summary

The webrix-docs1 npm package version 10.2.11 includes a preinstall hook that runs automatically on installation. This hook executes a Node.js script that gathers hostname, platform, architecture, user identifiers (username, uid, gid), shell, home directory, CPU and memory statistics, current working directory, and outputs of whoami and id commands. The collected data is sent as a JSON payload via HTTPS POST to a hardcoded Burp Collaborator (oastify.com) subdomain controlled by the attacker. The package lacks legitimate metadata and mimics the name of a legitimate project, consistent with a dependency confusion or typosquatting attack vector. Installing this package leaks sensitive host and user information to an attacker-controlled server.
