How to view the Cipher Suites being presented in Wireshark to confirm matching Ciphers


  1. When capturing the pcap, you will need to restart the sensor services to trigger a new connection attempt and handshake. 
    • Windows (cmd as admin)
      sc stop carbonblack
      sc start carbonblack
    • Linux (Terminal)
      sudo service cbdaemon restart
      sudo systemctl restart cbdaemon
    • macOS (terminal)
      sudo launchctl unload /Library/LaunchDaemons/com.carbonblack.daemon.plist
      sudo launchctl load /Library/LaunchDaemons/com.carbonblack.daemon.plist
  2. Open the pcap in Wireshark.
  3. Look for the "Client Hello" packet to the destination IP of the EDR Server and expand
    • Expand Under "Transport Layer Security" -->
    • Expand"TLSv1.2 Record Layer: Handshake Protocol: Client Hello"
    • Expand "Handshake Protocol: Cipher Suites ( 2 )" -- within brackets are number of cipher suites the endpoint presented
    • After expand to see the Ciphers being presented by the Endpoint to the EDR server
