# all my knowledge about capture the flag

[capture the flag](https://en.wikipedia.org/wiki/Capture_the_flag_(cybersecurity)) 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](https://ctftime.org/).

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.
