Getting the most out of Evil Twin with wifiphisher — BSides Athens 2016

My last year’s talk at BSides London introduced to the public Wifiphisher, a security tool that mounts the Evil Twin attack against Wi-Fi networks. The tool has since seen some heavy use by the wireless hacking community which has inspired further research into ways of making the Evil Twin attack more effective.

The road to efficient Android fuzzing

In the aftermath of the recent Android stagefright vulnerabilities, efficient fuzz testing techniques and tools for the Android ecosystem are again in the spotlight. In this post we would like to share some of the fuzz testing experience we have gained through our projects and show how it can be applied in the Android world. Additionally, we’ll enlist some of the public contributions we’ve made to open source tools aiming to help the community focus more on the target and less on the tooling.
