What is a CTF? CTFs, or Capture The Flag competitions, are events focused on computer security and hacking. In these competitions, participants engage in activities such as breaking into systems, investigating vulnerabilities, reverse engineering, and using various techniques to achieve a specific goal: finding a 'flag,' which is typically represented as a string of text. One of the most famous and earliest major CTFs is hosted by DEF CON, which takes place annually at the hacking conference in Las Vegas. Since then, many different competitions have emerged, with numerous events held throughout the year. A great resource for tracking CTF schedules is ctftime, an active website that features calendars and team rankings. Example: A very simple type of CTF challenge involves examining the source code of websites or programs to discover flags and/or hints.
