DeepSec Video: Visualizing Wi-Fi Packets the Hacker’s Way

Like the Force wireless data/infrastructure packets are all around us. Both have a light and a dark side. It all depends on your intentions. Lacking the midi-chlorians we have to rely on other sources to get a picture of the wireless forces in and around the (network) perimeter. At DeepSec 2015 Milan Gabor held a presentation about visualisation of wi-fi packets:

Today visualizing Wi-Fi traffic is more or less limited to console windows and analyze different logs from an aircrack-ng toolset. There are some commercial tools, but if we want to stay in the Open/Free Source Code (FOSS) area we need to find better solutions. So we used ELK stack to gather, hold, index and visualize data and a modified version of an airodump tool for input. With this you can create amazing dashboards, correlate some interesting data and do some deep digging for Wi-Fi packets. It gives hackers and also administrators a quick view into Wi-Fi space and offers a range of new possibilities to get interesting data really fast.

One half of the talk will be dedicated to a presentation of how this can be done, telling you about some issues that we had and solutions to them, while the rest of the talk will be demonstrating the true power of our research.

Have a look and implement it for your network!
