Malicious code in bcc-design-icons (npm)
The npm package bcc-design-icons version 9999.0.0 contains malicious code that executes a postinstall script during installation. This script sends the host's identifying information, including the hostname, to an attacker-controlled IP address without user consent. The package appears to be part of a dependency confusion attack, as it lacks expected functionality and uses a suspicious version number.
AI Analysis
Technical Summary
The bcc-design-icons package at version 9999.0.0 declares a postinstall script that runs automatically on npm install. This script performs an HTTP GET request to a hardcoded bare-IP endpoint (http://91.201.215.48:8000/npm-poc-bcc) with query parameters including the operating system hostname and the package name. The version number and behavior suggest a dependency confusion attack designed to identify internal or private installers by exfiltrating host-identifying data to an attacker-controlled server without any installer opt-in.
Potential Impact
The malicious postinstall script exfiltrates host-identifying information (hostname) to an attacker-controlled server, potentially exposing internal network details or private environment information. This can aid attackers in reconnaissance and further targeted attacks. There is no indication of additional payloads or direct system compromise beyond data exfiltration in the provided information.
Mitigation Recommendations
No official patch or remediation is indicated for this package version. Users should avoid installing bcc-design-icons version 9999.0.0. Verify package authenticity before installation and prefer official, trusted package sources. Monitor for suspicious postinstall scripts in npm packages. Patch status is not yet confirmed — check the vendor advisory or npm security advisories for updates.
