The Grand Reverse Engineering Challenge runs in two rounds: Round 1 starts May 21 and Round 2 starts July 3. The competition ends midnight, anywhere on earth, July 18. The total prize sum is USD 10,000. All individuals are welcome to participate. The only requirement is that you run our data collection framework in the background (typically within a Linux virtual machine) as you solve the challenges. The data collected will be published (anonymized, of course) and used to learn how reverse engineers solve problems in practice.
UPDATE: We have received several attack attempts and one correct solution to challenge 5! Round 2 challenges are now available for download. Two of the new challenges have only very light protection. You can still download and attack the round 1 challenges.
