Hackers from All Over the World Competed to Join PHDays IV CTF

PHDays CTF Quals, an information security competition, took place from 12 p.m. on January 25 to 12 p.m. on January 27, with teams competing for the entire 48 hours. Dragon Sector, a Polish team, won the contest, though quite unexpectedly, PPP, from the USA, took second place and More Smoked Leet Chicken, from Russia, came in third.

The main feature of this Quals (as compared to the previous years' competitions) was a special quest game. Teams solved it in order to earn points, which were used to open CTF challenges and then to earn final points. The plot of the quest was based on the legend, which was the part of PHDays III CTF. This year, teams needed to work shoulder to shoulder with the Golem Special Division and investigate an incident related to the spreading of the Detcelfer Worm.

This year the heat of the struggle exceed all expectations:

  1. 627 teams registered to participate in the competition
  2. 418 of them solved at least one challenge during the quest game
  3. 276 teams solved at least one CTF challenge
