Hacky Holidays is an online game hosted on the Deloitte Hackazon platform, where you can test and improve your skills with all sorts of challenges (technical puzzles) related to cyber security and emerging technologies such as cloud, product security and identity and access management. Do you have what it takes to solve all the challenges and capture all the flags?

About Hacky Holidays

Hacky Holidays is a holiday-themed online game during which you can solve all sorts of technical puzzles related to cyber security (such a game is also known as a Capture the Flag, or CTF in short). Each of the challenges have a task description which give you a clue on how you can solve the particular challenge. An example challenge could be a web application in which you need to find a vulnerability that gives you administrative access. When you have successfully solved a challenge you will be given a flag, which is a piece of text, most of the times formatted as following: CTF{…}. When you find the flag you can enter it under the challenge description’s input field and you will be allotted the points assigned to the challenge. Each flag gives you a certain number of points that are counted towards your total score. Your score and those of other players can be seen on the scoreboard of the event.
