Capture The Flag

“Knowing is not enough; we must apply. Willing is not enough; we must do.” - Johann Wolfgang von Goethe.

In simple words, Capture the Flag (CTF) is a computer security competition. It distils major disciplines of professional computer security work into short, objectively measurable exercises.

The Pragyan version is an ethical hacking contest in which certain pieces of information called ‘flags’ are hidden in the challenges. Bring a team ready to be tested on the nuances of network security to solve real-world problems, on their way to capture the flag.

  • There will be a set of challenges from a range of categories like Cryptography, Web, Forensics, Steganography, Reverse Engineering, Binary Exploits, etc. 
  • The challenges can either be a collection of files that they can download and find the “Flag”, or they can be running as web-services to which the participants connect and exploit to get the Flag.
  • Each category contains a variety of questions with different point values and levels of difficulty.  The participants will be ranked based on their scores, and the time taken will be used in case of a tiebreaker.
