Tech Thursday: Making Your Own Wireshark Dissector for Mysterious and Unknown Protocols

Presenter: Doogie

NAC-ISSA and DC256 present our second Tech Thursday of 2026 at Gigaparts on Feb 19 at 6:00PM. This hands-on workshop moves beyond filtering and display into the craft of understanding undocumented protocols and using that knowledge to create a reusable Wireshark dissector.

Attendees will walk away with their own network protocol dissector that can be used in any Wireshark instance.

Attendees should already understand networking basics, such as the OSI model, IP addresses, MAC addresses, the differences between TCP and UDP, and the concept of port numbers. Familiarity with Wireshark is recommended.

The event is open to anyone interested in cyber security, is free and pizza will be provided.
