Yet Another CTF is a computer security competition organized by Yandex and run by SPbCTF crew.

CTFs are competitive hacking events: like ACM ICPC, but in computer security. Participants get a number of tasks or challenges about cryptography, binary reverse engineering, web vulnerabilities, network security, digital forensics, etc — all the topics that computer security engineers work with.
Each challenge has a goal, e.g. to find a vulnerability and extract the administrator's password from the website database. Upon solving the challenge, the player gets a flag — some secret string like yactf{fl4g_ex4mpl3}. Participant submits it in exchange for points. The competitor with the most points wins. To be successful in a CTF, you basically need to know computer systems well and deeply.

Yet Another CTF is an individual competition open to stand alone participants.
YaCTF will be a Jeopardy-style competition. Competitors will receive a set of challenges from various areas of practical security, ranging from basic to interesting.
Dynamic scoring will be used: the more competitors solve a challenge, the less it will cost in the end.
If there are several competitors who gain the same number of points, the winner is the one who solved his last challenge earlier.

• 1st place — 150 000 RUB
