We are pleased to announce the conclusion of the fifth annual
Flare-On Challenge. The numbers are in and we can safely say that this
was by far the most difficult challenge we’ve ever hosted. We plan to
reduce the difficulty next year, so it may be that the 114 people who
solved this year’s challenge solved not only the most difficult
Flare-On to date, but the most difficult Flare-On there ever will be.
The prize for these amazing and dedicated Reverse Engineers is a magic
decoder buckle and coin insert. It can be used to decode and encode
secret messages using a pre-shared key. It is based on a crypto system
known as a Diana Cipher. They will be shipping soon.
We would like to thank the challenge authors individually for their

And now for the stats. As of 10:00am ET, participation was at an
all-time high, with 4,893 registered players and 3,374 players
finishing at least one challenge. This year had the least amount of
finishers as well with 114.
The U.S. continues to slip further down the ranking in terms of
finishers by country. China takes the lead in overall finishers and
Singapore is the undisputed champion of per capita finishers with more
than one finisher per million people.
All the binaries from this year’s challenge are now posted on the
solutions written by each challenge author:
