Booty Wireless CTF


[This is a write-up of Wasabi's experiences at the 24 hours of Booty, wireless CTF at Unallocated Space. This Wireless CTF was organized by @rmellendick of Defcon's Wireless Village fame. Rick and @DaKahuna2007 also organized last year's wifi CTF for BSides-DC. In fact many of the challenges are the same (Write-up here).]

This version was a sprint of what will be done at DEFCON.
