Greetings all,

I am trying to do a little research on ja3. I have some ssl traffic pcaps that I am ingesting into SO via the so-import-pcap script. The script runs as planned, but I do not see any ja3 info in kibana. Is this typically located in the SSL section? I have checked the local.bro and ja3 is not commented out.
Any suggestions? Thanks

Brandon

Hi Brandon,

Yes, the ssl.log should contain ja3 and ja3s fields.  I just tested on the current 16.04.6.1 ISO image with "sudo so-import-pcap /opt/samples/mta/*.pcap" and it seems to be working fine for me:

Doug,

Thanks! I did see the logs in the /import directory. For some reason I thought that they were a default visualization in Kibana. I added the the ja3 and ja3s to the dashboard and everything is working as it should. Thank you again.

Brandon
