Hello Codeforces!

Reply will be hosting the Reply Cyber Security Challenge, at its fourth edition, a team competition open to both students and professionals aged 16+. Is this only for cyber security experts? Nope :) This challenge is open to everyone with coding skills, passionate about technology and in love with solving riddles and logical problems.

The online competition will take place on Friday October 15th 2021 at 19:30 CEST and will last 24 hours.

Your team can have 2 — 4 people. Registrations will close on October 14th!

The challenge will present five stimulating issues of increasing difficulty for each of the following categories: coding, web, miscellaneous, crypto, and binary. The team that solves the security problem in a 'capture the flag' (CTF) contest will obtain the highest score in the challenge and win the challenge. Designed by the Keen Minds team, Reply's cyber security experts, the Cyber Security Challenge is just one of a number of Reply initiatives to promote the culture of coding, with a particular focus on new generations.

Up for grabs: for each member of the winning team a XMG gaming laptop, an Oculus Quest 2 for the second and a razer gaming keyboard for the third.
