Attackers hijacked the npm account of Axios's lead maintainer and published two poisoned versions of one of JavaScript's most popular libraries - 83 million weekly downloads. Versions 1.14.1 and 0.30.4 inject a hidden dependency called plain-crypto-js that drops a cross-platform RAT targeting macOS, Windows, and Linux. The malware phones home within seconds of npm install, then deletes itself to avoid detection. Both release branches were hit within 39 minutes of each other.
