Hi Phoenix,

I would recomend using a combination of file upload and threat match detection type.

Ensure your csv has a timestamp column or use a pipeline during fileupload to add a @timestamp field with the now value. This is required for the detection.

  1. Open the integrations page and search for csv
  2. Select the "upload a file" integration

  3. go through the steps and use a specific index as destination, e.g indicators_from_csv; Take not of the column/fieldname in which you indicator is stored (ip/hash/url)
  4. Navigate to the siem rules and create a new one
  5. Use the indicator match type and fill out the source, query etc as best applies. e.g:

  6. Fill out your detection details and use a bigger lookback period if you want to search historicaly.
  7. Save and enable you rule.
