Wireless traffic analysis has been commonplace for quite a while now, frequently used in penetration testing and various areas of research. But what happens when channel hopping just doesn't cut it anymore -- can we monitor all 802.11 channels? In this presentation we describe the analysis, different approaches and the development of a system to monitor and inject frames using routers running OpenWRT as wireless workers. At the end of this presentation we will release the tool we used to solve this problem. Speaker Bios: Andrés Blanco is a researcher at CoreLabs, the research arm of Core Security.
