Handcrafted Packets: Build network packets with Scapy
Uli Heilmeier

• You want to reproduce a network problem for specific frames?
• You want to test a Wireshark dissector you’ve developed but a sample capture is missing?
• You want to test whether an application reacts to all defined commands?
• You do a penetration test and want to see how a network device handles undefined data (e.g. with TCP MSS=0)

For all these cases, Scapy can help you build the packets you need. In this talk, I will show you how to do it. Scapy is
a packet manipulation tool written in Python. It can forge or decode packets, send them on the wire, capture them, and
match requests and replies. At the end of the session, we can assemble packages together in a hands-on session. => Bring
your laptop with you.

WTSC election report
Uli Heilmeier

This year was the first time that the election of Wireshark Technical Steering Committee (WTSC) members took place.
In this session we want to report how the election went, how it was organised, what we learned for the next time and why "a few emails and validating and counting responses and maybe a couple of online meetings for the EC folks" is not enough.
