Threat Actors Weaponize Trusted Node.js Runtime for Stealth Malware Delivery
Since February 2026, threat actors have been weaponizing the legitimate Node.js JavaScript runtime (node.exe) to deliver malicious payloads in targeted attacks against government departments, technology companies, and hotels. The Symantec Threat Hunter Team identified this technique as particularly effective because node.exe is a trusted binary that can execute arbitrary JavaScript code while evading traditional security detection mechanisms. Attackers leverage the runtime's legitimate presence in enterprise environments to establish persistence, execute malware, and maintain command and control communications without triggering security alerts. This campaign reflects the growing trend of living-off-the-land tactics where attackers abuse legitimate system tools rather than deploying custom malware, making detection significantly more challenging for traditional security solutions and highlighting the need for behavioral analysis and runtime protection.
