What is a CTF?

A CTF (Capture The Flag) is an information security competition where contestants solve a variety of tasks to find the hidden “Keys”.

In a Jeopardy-style CTF like QCTF, these keys are found in a variety of challenges across many different fields of computer science. Below are some the categories you might encounter.

Reverse engineering

Exploiting a binary file to make it behave unexpectedly

Steganography

Finding information hidden in text, files or images

Cryptography

Decrypting or encrypting a piece of data

Web exploitation

Exploiting web pages to find the flag

Remote exploitation

Exploiting a server or remote service to find the flag

The Queen’s Capture the Flag is an annual event run in partnership with the Queen’s Engineering Society that allows Queen’s University students interested in cybersecurity and other fields of computing and information technology to learn technical skills through friendly competition. This hands-on experience provides a space for participants to learn and practice skills seldom taught in academia or other extracurricular events

Details for the 2021 version of QCTF are still in the works...
