About The Project This past weekend was the final Shmoocon and the final Hack Fortress….for now. This blog post is a writeup on developing an 802.11 challenge for Hack Fortress while considering the congested 802.11 environment that is the Shmoocon conference. By leveraging the Linux kernel’s hwsim and hostapd, competitors were able to capture beacon frames, parse SSIDs, and ultimately solve a 802.11 challenge that never actually broadcasted a beacon frame over RF!
