The registration for RHME3 is now open! Click here to register and access challenges.

We would like to welcome teams and individuals to register and try their skills at solving the welcome challenge for RHME3. This year it’s not one but three challenges in total. Here’s how RHME3 registration works:

• The registration is open from August 7 12:00 CET.

• The registration closes on August 28 at 12:00 CET.

• We only need your [nick]name and e-mail.

• Feel free to register, download and solve challenges in any order.

• Submit flags when you capture them. Do not share the flags with others, don’t spoil the fun.

• After August 28 we will announce the winners and contact them to ask for a physical address to ship the board.

• Every welcome challenge gives you one point. The score counts towards your overall RHME3 progress.

• Even if you plan to participate in the main challenge as a team, please solve the welcome challenges individually.

• We rank the results based on the number of challenges solved and dates of flags submission:

o Those who solved all three challenges and were the first to submit the flags.

o (If boards are still available) Those who solved at least two challenges and were the first to submit the flags.

o (Very unlikely to get a free board, but who knows) Those who solved at least one challenge and were the first to submit.

• In total there will be 500 participants with the best results to get the RHME3 board for free. You will need the board to solve the main challenges starting from November 1.

About RHME3

• Embedded systems CTF created by Riscure in partnership with Argus Cyber Security. The global CTF with an automotive theme.

• Allows participants and interested parties to enhance their knowledge of embedded systems security in general, and hardware security in particular.

• For the first time participants are provided with challenges that simulate real-life scenarios relevant to automotive cybersecurity: a group of challenges co-developed by Argus and Riscure utilizes CAN protocol commonly used in modern cars.

• A special Arduino-compatible custom board has been developed for the RHme3 challenge.

• In total there will be 500 “open registration” participants with the best results to get the RHME3 board for free. You will need the board to solve the main challenges starting from November 1.

• The core of the board is an Atmel XMEGA that has four times the memory and is twice as fast than the previous RHme boards.

• The RHme3 board also has a crypto-hardware accelerator and two CAN controllers, which allow a whole new range of challenges.

• The registration for RHME3 (with three welcome challenges) starts August 7 and concludes August 28. The main challenge starts November 1.
