HackQuest is Completed. Best Reverser is Ready to Start

The epic hacking competition PHDays HackQuest has come to an end. The competition was organized by ONsec_Lab. It lasted from May 1 to 13 and drew 1441 participants, 112 of them solved at least one task.

The racing continued right to the last minute. The top three was stable until the end of the contest: JustRelаx, MERRON, Bo0om. However, the sly tactics of capturing flags two minutes before the ending allowed one of the participants, namely karim, to win the contest. Bo0om also captured another flag at the last moment and left MERRON on the fourth place, from which he was overtaken by Yngwie.

So karim, who was the fourth not long before the end of the contest, won by 50 points. JustRelax being the leader throughout the contest took second place. Bo0om came in third.

We’ll keep our promise: 10 participants who showed the best results will get invitations to Positive Hack Days and special T-shirts (1 place — 5 tickets, 2 place — 4 tickets, 3 place — 3 tickets, from 4 to 10 place — 1 ticket per participant). Moreover, the top three participants will get diplomas.

The task of factorization of RSA 512 bits gained plenty of interest. The winner of the contest is karim from the Bushwhackers team. It took him 190 CPU hours of 20 CPU Intel XEON (32 threads each) to solve the task. By the way, karim is the only one who manage to solve the task.

Moreover, many participants found the oldbook contest quite entertaining. During the contest, the participants were searching for the oldest book about computer sciences. Due to the publication date of the find, additional points were scored (100 points for every 5 years).

Here are the oldest publications that the participants managed to find:
  • Svoboda, A., Computing Mechanisms, Moscow, Foreign Languages Publishing House, 1949
  • Murray, F., The Theory of Mathematical Machines, Moscow, Foreign Languages Publishing House, 1949

There is another book that is worth mentioning: Voronov, A., Elements of the Theory of Automatic Control, Moscow, Voenizdat Publishing House, 1954.

Almost half of the participants solved the task of finding out the real name of the ONsec CEO, Vladimir Vorontsov.

The value of the unsolved tasks increased every day, and some difficult tasks were simplified during the contests (sidkf, xlc, LIE TO ME etc.).
