On March 30, 2026, StepSecurity discovered two malicious versions of the popular axios HTTP client library (versions 1.14.1 and 0.30.4) published to npm using compromised maintainer credentials. The malicious packages injected a fake dependency that deployed a cross-platform remote access trojan targeting macOS, Windows, and Linux systems. The sophisticated supply chain attack was pre-staged over 18 hours and designed to self-destruct after execution, making it one of the most operationally advanced attacks against a top-10 npm package.
