How to Play
This year there are three short CTF tracks focusing on different domains of security expertise. The tracks are independent and will have a prize for the first person or team to solve a track. There are also interactions across tracks. You must complete the ShadyBank challenge to fully complete the Olmstead Challenge. You will encounter web, cryptography, rf, and remote memory corruption if you participate in all tracks.
The ShadyBank Challenge/Response
Go to ShadyTel Experience Center to register your Shady Tag.
The first challenge is on the badge.
Don't give up, don't let me down.
Don't tell me you're too blind to see
Inside, we both know what's been going on
We know the game and we're gonna play it!
The Olmstead Broadcasts Challenge Set
There must be something in the air,
the tale of Roy and Elsie Olmstead
is on everyone's lips. Murmurs of an
illicit moonshine operation in this era
of prohibition. You can hear it if you
listen closely and open your eyes!
