On March 30, 2026, malicious versions (1.14.1, 0.30.4) were published to npm, injecting a dependency (plain-crypto-js@4.2.1) that executed a postinstall script as a cross-platform RAT dropper.
The dropper contacted a C2 server, delivered platform-specific payloads, deleted itself, and replaced package.json to evade detection.
