For many people Reverse Engineering sounds like magic, but it's yet another methodology to understand what soft- and hardware is doing. This session will cover the methodology and tools that are used in our company to answer very specific customer questions relating to software. The purpose of the talk is to demonstrate a timely effective approach to analyze software that is only available as a binary. After the talk the audience will know what kind of knowledge is really needed to do reverse engineering, which tools are recommended to do the job (Hey-Rays, the new decompiler plugin for IdaPro and Autodebug, a mighty debugger and api monitor will be demonstrated) and how a structured approach can help you to accomplish the task in a reasonable amount of time.
