Date: 2026-03-31 | Attribution: BlueNoroff / Lazarus Group (HIGH confidence) Attack: Maintainer account hijacked, cross-platform RAT deployed via axios@1.14.1 and axios@0.30.4
On March 30-31, 2026, the npm package axios (~83M weekly downloads) was compromised through a maintainer account hijack. Two malicious versions injected plain-crypto-js@4.2.1, an obfuscated dropper that deploys platform-specific RATs (Windows PowerShell, macOS Mach-O C++, Linux Python). The macOS RAT is classified as NukeSped (Lazarus-exclusive). The internal project name macWebT links directly to BlueNoroff's documented RustBucket webT module from 2023.
