Reverse Engineering Network Device APIs
Dan Nagle (@NagleCode)

This presentation is a live demonstration on how to use Packet Sender plus Wireshark to reverse engineer a black box networked device ( -- for this demonstration, a Raspberry Pi running custom TCP and UDP servers). The goal is to bypass the device's original software. After the box's capabilities are acquired, it can then be extended by Packet Sender. During the demonstration, broader ideas with regards to network programming will be discussed. Anybody who is interested in software development is highly encouraged to attend.
