Reverse Engineering Network Device APIs - Dan Nagle (@NagleCode) (BSides Huntsville 2014) (Hacking Illustrated Series InfoSec Tutorial Videos)

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.

Bio: Dan Nagle is a senior software engineer for SVSi writing control software and web interfaces for network devices distributing HD video over computer networks. He has written apps for Android, Windows, Mac, Linux, iOS, numerous web apps, network servers, and pure embedded C. He is the author of the book "HTML5 Game Engines" published by CRC Press. He is the author and inventor of Packet Sender, a cross-platform packet-generation and network test utility. He has also been published in Net, a London-based magazine about web development.
