description: |
    Detects file creation events linked to the Axios NPM supply chain compromise. Axios is a popular JavaScript HTTP client.
    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.
