Participate in new challenges every day

You participate in talks and workshops, you talk with every company you can and participate in every tournament. Now you are left with a bunch of badges, what do you do?! Every badge comes with a set of entries to the Final Badge Draw! On the last day of SEI, we will select three winning entries and their owners will be the lucky recipients of an amazing selection of prizes! The more badges you have, the more likely you are to win!

This one is easy. The winners are the three people with the most badges won on the first day! If there is a tie, the participant with the most tokens at the end of the day wins! If there’s still a tie after that, we’ll toss a coin! The badges you win before SEI starts will be counted on this day.

The same rules as day one apply. However only the badges you win on the second day count towards this prize.

The same rules as day one (again). However only the badges you win on the third day count towards this prize.

This is getting a little repetitive… The same rules as day one (again). The difference is that only the badges you win on the fourth day count towards this prize.

Think you’ve got what it takes to conquer our programming quizzes? Time to put your skills to the test—using your favorite programming language, of course (yes, even if it’s JavaScript, we won’t judge… much).

Whether you’re a seasoned dev who dreams in regex or a brave soul still debugging that one off-by-one error, this is your chance to flex your coding muscles, learn something new, and maybe even take home an incredible prize.

Tell us the result at the accreditation and receive your badges.

Wait, what?! You can upload your CV, make it available to our sponsors, and get a shot at winning an amazing prize? Sounds like a win-win — what more could you ask for?

Think you’ve got what it takes to crack our challenges? Time to put your cybersecurity skills to the test—no, not by googling the answer (we see you).

During the event, you’ll face two challenges designed to make you think like a true hacker. Be the first to uncover the hidden flags, and you’ll not only earn ultimate bragging rights but also a special badge — plus, the award shown below.

Note: Flags will always follow this format: seiCTF{some_text}. And no, seiCTF{please_give_me_the_flag} won’t work… but nice try.

To redeem the badges you must say the flag in the accreditation.
