This year, Square is hosting the first Capture the Flag security competition to run alongside the Grace Hopper Celebration. We have a variety of interesting challenges that mirror security vulnerabilities found in the wild. Participation is open to everyone, but in order to be eligible for our sweet prizes (Macbook Airs, HackRF Ones, and ODroid XU4s), you must be an attendee of GHC 17 and solve an on-site Grace Hopper challenge. Square infosec will be present at the Square booth (Booth #1901) at the career fair to answer any questions! We have an accompanying workshop on how to participate in a CTF (zero security knowledge necessary!) on Thursday from 1:30-3:30PM in OCCC W308C. Bring a laptop!

I too am not able to click confirmation. I think there is some issue with it. #squarectf please look into it.

No public scoreboard for all participating teams is a really, really dumb idea.
