Description

The npm package 'bigops-products-mobile' version 35.6.8 contains malicious code that performs remote code execution on the host system upon installation and import. It downloads attacker-controlled binaries from obfuscated Cloudflare Workers domains and a DNS-TXT fallback, writes them to disguised file paths, sets executable permissions, and executes them without any integrity verification. The package masquerades as a device integration tool but includes hidden persistence mechanisms and telemetry-like comments to evade detection.

Impact

Installing and importing this package leads to remote code execution on the host system, allowing attackers to run arbitrary code with the privileges of the user installing the package. This can lead to full system compromise, data theft, or further malware deployment. The malicious behavior is hidden behind legitimate-looking telemetry and device integration claims, increasing the risk of unnoticed compromise.

Defensive guidance

Users should immediately avoid installing or importing version 35.6.8 of 'bigops-products-mobile'. Remove the package if already installed and perform a thorough investigation of the host for signs of compromise. Monitor for suspicious network connections to the indicated Cloudflare Workers domains and the DNS-TXT fallback domain. Consider blocking these domains at the network level. Check vendor advisories or trusted security sources for updates on remediation.

Summary

The 'bigops-products-mobile' npm package (version 35.6.8) includes a malicious payload embedded in its index.js and lib/telemetry.js files. Upon requiring the package, it loads _loader.js which dynamically constructs URLs to attacker-controlled Cloudflare Workers hosts and a DNS-TXT fallback domain to fetch binary payloads. These payloads are saved to disguised filenames ('.cache_<hex>' on POSIX systems, 'dotnet_diag_<hex>.exe' on Windows), made executable (chmod 0755), and executed detached from the parent process using shell commands. No hash or signature verification is performed on the downloaded payloads. The package also writes a persistence marker file '.analytics_state' with telemetry-style comments and environment variable checks to disguise its malicious behavior. This results in remote code execution on the installer's host under attacker control.
