Does Panther support asciinema logs?
Panther does not natively support ingesting asciinema logs. As a workaround, you can use a custom log source with the following regex event exclusion filter:
This would exclude the first header line and leave behind each event as a JSON Array, similar to the following:
[0.248848, "o", "\u001b[1;31mHello \u001b[32mWorld!\u001b[0m\n"]
Then you can create a custom schema for each of those events to successfully ingest and write detections against.
