Online Capture the Flag
MAGIC’s Online Capture the Flag competition is an online version of our popular hosted event. While the look and feel is different, we have continued to provide a beginning level of competition for novices.
Instead of a local VM(virtual machine) instance used in our hosted event, the online CTF utilizes a web browser that is accessible from any computer with a browser. This allows the competitor to participate in the online version from anywhere they have internet access.
This version is also slightly more difficult as the individual is responsible for managing their own tools and environmental resources to compete. And because this is totally virtual, no industry professionals are available to coach or give hints on the challenges.
Our challenges are broken down into difficulty levels. Level 0 challenges are basic introduction puzzles that allow the participant to “get into" the competition. Level 1,2, and 3 puzzles become progressively more difficult and will required additional time. We also have two challenge levels specific to an operating system.
A Linux level with challenges specific to the Linux operating system. You will need an installation of Kali Linux to solve these puzzles.
The second is a Windows level. These puzzles are specific to a windows operating system and you will need an installation of Windows to solve this level. These 2 levels are more complex, but will gain you more points when solved.
The online competition allows MAGIC to expand our cybersecurity learning opportunities to interested people that would not ordinarily attend a live event. Each has it’s positives and negatives. You choose which is right for you!

By creating an account and participating in the competition challenges, you are agreeing to these competition rules with respect to the current competition.
- Individuals and/or Teams may not interfere with the progress of other individuals/Teams, nor with the operation of the Competition’s infrastructure. More specifically, attacking the scoring server, other Teams, or machines not explicitly designated as targets is cheating. This includes both breaking into such machines, and denying others access to them or the ability to solve problems. Sharing keys or providing overly-revealing hints with other teams is cheating, as is being directly assisted by personnel outside the Team (using tools from the internet is OK; asking people on the internet to help solve the problem is not). We encourage Participants to solve problems in novel and creative ways using all available resources, but we do require that Participants solve the problems themselves.
- All information provided to establish an account must be true and correct. You are responsible for keeping such information up-to-date. Failure to keep your account up-to-date may, among other things, jeopardize your eligibility to compete.
- You must utilize appropriate username and team id’s. No usernames and IDs will be allowed that promotes a negative connotation or meaning. MAGIC will disqualify a participant if we deem inappropriate ID’s are being used. This includes icons and emojis.
- MAGIC runs an honest, ethically responsible competition. At any time, in the sole and absolute discretion of MAGIC, we shall be entitled to disqualify a Participant and/or Team in the event of a failure to meet relevant eligibility criteria or any other violation or suspected violation of these Competition Rules.
- Professional teams and teams that have professional skill levels should not participate in this beginner level educational competition. Professional or ranked teams will automatically be disqualified at the end of the event.
- Competition problems(challenges) or other content on the MAGIC site remains the property of MAGIC. MAGIC reserve any rights in such materials. You are authorized to access and use such materials solely with respect to registration for and/or participation in virtual CTF by you. You may not use the MAGIC site or any materials on it (including but not limited to the Competition problems) for any unauthorized purpose.
- In this competition, tie breaks are essentially resolved by time. If two teams have the same score at the conclusion of the competition, the team with the oldest score time stamp will be declared the winner.
Prize are determined for the top 3 teams after the completion of the competition. The prizes are:
$100 electronic gift card from Amazon for each member of the 1st place team
$50 electronic gift card from Amazon for each member of the 2nd place team
$25 electronic gift card from Amazon for each member of the 3rd place team.
A $25 electronic gift card from Amazon will be awarded to teams that locate and document any Easter Eggs that may be present during the competition. I.E. a missing line of code, a wrongly formatted flag, etc. Be the first team to find it and you and your team member will get the reward!
All Electronic gift cards are purchased in US funds from the .com site. The gift card is the final prize and cannot be cashed in or converted to another method of payment.
MAGIC will determine and announce the top 3 teams after the competition ends. MAGIC reserves the right to disqualify any team that is found not conforming with the Rules of the competition. Any ties for the top 3 slots will be determined by time stamps on the teams in question. Oldest time stamp(who scored the points first) will win.
Looking for help during the competition? Well, we can’t give answers or hints, but if you have technical or general questions, a live chat will be available during the competition. Just select the word bubble that will appear when the competition begins.
You can can also send us an email at firstname.lastname@example.org with general questions before the competition.
Available resources to connect with your teammates:
As your team will be spread out during the competition, you can utilize several team collaboration tools to communicate with them. All the resources listed are free to use.
You can also utilize other means of communicate such as Facetime, text messaging, etc.
Tips for your team during competition:
Each level and challenge is available for solving. Your team does not need to answer the challenges in order or one at a time. Each team member can work on a different puzzle at the same time if they so desire. Only one team member can input an answer to a particular challenge. Once that puzzle is solved a check mark will appear next to it confirming the puzzle has been solved. You can work together to solved each puzzle or you can divide and conquer. Hit your browser refresh occasionaly to confirm a puzzle has not be solved yet. There is no wrong way to work.
We don’t limit the attempts on puzzles. You can make as many attempts as needed to get the correct answer. This is a learning experience. We want to you solved every puzzle. We also do not deduct points for any of our Level 0 puzzles that have hints attached. However, points are deducted from the more difficult, higher level puzzles that contain hints. Be very careful asking for a hint as the “cost" points will be deducted from the team score immediately. Also remember, your answers are case sensitive.
Tools and Resources
Unlike our location CTF’s, this competition is completely virtual. To help competitors out, we have included a built in helper tool called CyberChef.
CyberChef is a simple, intuitive web app for carrying out all manner of “cyber” operations within a web browser. These operations include simple encoding like XOR or Base64, more complex encryption like AES, DES and Blowfish, creating binary and hexdumps, compression and decompression of data, calculating hashes and checksums, IPv6 and X.509 parsing, changing character encodings, and much more. You can find the tool button located at the bottom of your browser window. CyberChef is a read only utility. It will allow you to see your input and outputs but will not allow changes to be saved within the app.
