Not to be outdone by Flare-On-8, Malwarebytes have released their own CrackMe challenge...

Rules of the contest

The rules remain mostly unchanged since the second edition. As before we have two parallel tracks of the contest:

  1. The fastest solve. The three earliest submitted flags win. The flag should be submitted along with (minimalist) notes about the steps taken to find it. (No detailed write-up is required.) Any updates about the known winners in this category will be appended to this post.
  2. The best write-up. The write-up will be judged by its educational value, clarity, and accuracy. The author should show their method of solving the CrackMe, as well as provide the explanation of the techniques used in the challenge. The write-up submissions closes two weeks after the start of the challenge.

In each track we will select three winners that will be rewarded with unique Malwarebytes swag. The first place winner in each category will additionally get any IT-related book of their choice. All the solvers are going to be listed in our hall of fame.

The flag is in format: flag{...}

Submissions to both contests should be sent as a private message to the Twitter account: @hasherezade.

Three weeks after the challenge started we will publish the closing summary, along with the detailed walk-through, provided by the author.

WARNING: We are sorry, but Malwarebytes employees and people who had the access to the CrackMe before the official publication are not allowed to participate.

Malwarebytes CrackMe – contest summary

Quote

On October 29 we published our third CrackMe Challenge and announced two parallel tracks for the contest: “The fastest solve” , and “The best write-up“.

In the first category (“The fastest solve” ), we got three winners already the first weekend following publication. Big congratulations to:

  • @nazywam
  • Suvaditya Sur (@x0r19x91)
  • @evandrix

Yet, even those of you who are not as fast could still join in the fun, and get a chance to win a prize in the second category. Submissions for the best writeup closed November 12 (two weeks after the Crackme publication)
