"description": "Detects the specific Windows execution chain and process tree associated with the Axios NPM supply chain compromise.\nOn 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.\nThe dropper contacted a C2 server, delivered platform-specific payloads, deleted itself, and replaced package.json to evade detection.\nThe attack used cscript.exe (VBScript), curl.exe (C2), and PowerShell masquerading as Windows Terminal.\n",
