    Article summary

    You can easily integrate LimaCharlie with VirusTotal to enhance your data enrichment and detections. You will need a VirusTotal API key in order to utilize this add-on.

    VirusTotal Data Caching

    The free tier of VirusTotal allows four lookups per minute via the API. LimaCharlie employs a global cache of VirusTotal requests which should significantly reduce costs if you are using VirusTotal at scale. VirusTotal requests are cached for 3 days.

    Once you have your VirusTotal API key, you can add it to the integrations section of the LimaCharlie web app.

    path: event/HASH
    op: lookup
    resource: 'lcr://api/vt'
    event: CODE_IDENTITY
    metadata_rules:
      path: /
      value: 2
      length of: true
      op: is greater than
