Threat actors are leveraging the trusted Node.js JavaScript runtime in multiple cyber attacks as a way to deploy malicious payloads.

According to a new report published by the Symantec Threat Hunter Team today, the attack method has been put to use in attacks targeting government departments, technology companies, and hotels since February 2026.

“The technique’s appeal is that node.exe (the binary that runs Node.js) is a legitimate, signed developer tool,” the Broadcom-owned cybersecurity division said in a report shared with The Hacker News. “The attacker’s malicious code lives in interpreted scripts rather than in a binary, making it less likely to trigger signature-based detection, while a registry Run key entry can relaunch the payload at every login.”
