The package has empty description/author metadata and no legitimate functionality beyond this beacon. The exfiltration fires automatically on `npm install` before any consumer code runs.
AI Analysis
Technical Summary
The 'tracker-cloudflare' npm package (version 1.0.0) includes a preinstall hook that automatically executes 'node index.js' during installation. This script gathers host identifiers such as hostname, user info, home directory, DNS servers, current working directory, and reads the contents of /etc/passwd and /etc/hosts. It then sends this collected data via HTTPS POST to a Burp Collaborator subdomain controlled by the attacker. The package contains no legitimate functionality and has empty description and author metadata, indicating it is solely designed for data exfiltration.
Potential Impact
Installation of this package results in unauthorized disclosure of sensitive system information and configuration files to an external attacker-controlled server. This can lead to privacy violations and potentially facilitate further attacks based on the exposed host environment details.
Mitigation Recommendations
No official patch or remediation is indicated. Users should avoid installing the 'tracker-cloudflare' package version 1.0.0. Remove any instances of this package from projects and audit dependencies to ensure no malicious packages are present.
