Malicious NPM Packages Deliver NodeCordRAT
IntroductionZscaler ThreatLabz regularly monitors the npm database for suspicious packages. In November 2025, ThreatLabz identified three malicious packages: bitcoin-main-lib, bitcoin-lib-js, and bip40. The bitcoin-main-lib and bitcoin-lib-js packages execute a postinstall.cjs script during installation, which installs bip40, the package that contains the malicious payload. This final payload, named NodeCordRAT by ThreatLabz, is a remote access trojan (RAT) with data-stealing capabilities. It is also possible to download bip40…
