Write-up

For those looking to learn or expand on their technical abilities these types of challenges can often be a good starting point with many participants choosing to document and publish their write-ups for every challenge completed.

Included as part of the SANS HHC is the option to submit your write-up for each challenge (prior to the deadline) to enter into the SANS Contest.

In January 2022, I successfully completed all of the challenges and submitted my write-up to the Counter Hack Team for the fourth year in a row.

This year I recreated the world of KringleCon IV as a playable JRPG game to deliver my write-up in a creative way, in addition to creating an ‘Edutainment’ series on YouTube.

I have chosen to do this to both challenge myself in creating this in such a short space of time, but also to highlight my challenge failures in an entertaining way.

Imposter Syndrome is fairly prevalent in this industry, so to highlight the time taken to solve challenges and some of the failures along the way, in my opinion, is a much needed addition which is rarely included in these write-ups.

My submitted entry was one of the 3 major prize winners of 2021, securing the “Most Creative” prize which was a welcomed change to the Super Honorable and Honorable mention achieved in previous years. Creating this did take a considerable amount of time to create, but it was well worth it.

I’d like to close by giving my thanks to this year’s speakers, HHC Team, challenge developers, and the concierge team, in addition to giving my congratulations to the rest of the Honorable and Super Honorable Entries, send my congratulations to all 222 people/teams who took the time to document and submit their reports, and also to all the players who participated in the SANS 2021 HHC.
