First place at Deloitte CTF Final

Having previously qualified in the online round, we (Alastair, Cecile, Chris, Emma, and Ilias) headed to London to participate in the Deloitte CTF final, with a cool £5000 in prizes to fight for.

The challenges were quite a bit more demanding than the qualifiers, and the competition was fierce, with Edinburgh getting closer to us and eventually overtaking. The last 4 minutes were intense: we were tied with Edinburgh at 3000 points, but they were leading. Then we submitted one more flag and shot to first place, and watched the clock tick down while hoping no one else got any more flags… which they didn’t!

Final rankings were as follows:

We solved 10 out of 17 challenges:

And here is the team, with an awesome check!
