“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 distills 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 cryptography, steganography, application security, binary analysis, reverse engineering and other real world problems on their way to capture the flag.

Prizes worth INR 80000


It will be a ‘Jeopardy!’ style 2-day online contest that happens during Pragyan 2018. There will be a set of challenges from a range of categories like Cryptography, Web, Forensics, Steganography, Reverse Engineering, Binary Exploits, etc. 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.

Embedded in the challenge, program, or system, will be a secret key, or a “flag”. Finding this flag is proof that you solved the challenge, and submitting it to the scoreboard earns your team points. Flags are typically chosen to look very distinctive, so that when you see one, you’ll know it’s a flag. Flags in Pragyan CTF will tend to be a phrase or sentence in 1337, for example, “welc0m3_t0_pr4gy4n_C1F”.




Each category contains a variety of questions of different point values and difficulties. The participants will be ranked based on their scores, and the time taken to solve the challenge will taken in case of a tiebreaker. The decision of the organisers will be final.
