Malicious code in content-publisher-sdks (npm)
The npm package 'content-publisher-sdks' version 1.0.1 contains malicious code that executes during installation. It runs a preinstall script that collects host system information and sensitive files, then exfiltrates this data to a hardcoded external server. This package mimics legitimate SDK packages but its sole purpose is data exfiltration during install.
AI Analysis
Technical Summary
The 'content-publisher-sdks' npm package version 1.0.1 declares a preinstall hook that executes 'index.js' upon installation. This script gathers host reconnaissance data including hostname, user info, home directory, DNS server list, current working directory, and package.json contents. It also reads sensitive files such as '/etc/passwd' and '/etc/hosts' from the installer's filesystem. The collected data is then sent via HTTPS POST to a hardcoded Burp Collaborator subdomain (ie02j5ztgjeb6i7tp467ydwnjep8dy1n.oastify.com). The package masquerades as a legitimate SDK but its only behavior is this malicious data exfiltration.
Potential Impact
Installation of this package leads to unauthorized collection and exfiltration of sensitive system and user information to an external attacker-controlled server. This compromises confidentiality of the host system and may expose user and system details to threat actors.
Mitigation Recommendations
Avoid installing the 'content-publisher-sdks' package version 1.0.1. Since no patch or fix is indicated, users should remove this package if installed and verify their environment for any unauthorized data exposure. Use trusted sources and verify package authenticity before installation.
