Summary : 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.
