all my knowledge about capture the flag

capture the flag is a wonderful activity in which one gets together with a merry band of friends to solve puzzles for the sake of solving puzzles and learning. such puzzles are often security-related.

capture the flag competitions (“ctfs”) are hosted by established teams, or security organizations, or corporations. there is typically at least one running at any given time: although most usually start fridays and run for a day or two. a list of past, present, and future ctfs can be found on ctftime.

while competing in ctfs can be group work: practice is overwhelmingly a solo activity. to get good at playing in ctfs, one must learn to be very comfortable learning on their own.
