CMU Cybersecurity competition

What is picoCTF?

picoCTF is a computer security game targeted at middle and high school students. The game consists of a series of challenges centered around a unique storyline where participants must reverse engineer, break, hack, decrypt, or do whatever it takes to solve the challenge. The challenges are all set up with the intent of being hacked, making it an excellent, legal way to get hands-on experience.

This year’s competition features a brand new adventure. When your friend disappears unexpectedly, you must learn and use computer security skills to uncover and decipher critical evidence behind their whereabouts. Can you find your friend before it’s too late?
