Capture the flag has been played for millennia. From outdoor games to video games, and even in the cyber security world. It’s used as a training tool to increase the competing hackers’ skills. The objective is to reverse engineer, break, hack, decrypt, and otherwise think creatively and critically to solve the challenges and capture the flags. Flags are secrets hidden in purposefully-vulnerable programs or websites. In these competitions, competitors steal flags either from each other or from the event organizers.
Some of the largest CTF competitions are DEF CON, FAUST CTF, and Pwn2Win RCTF. These competitions offer cash prizes in the hundreds of thousands of dollars. To be able to compete in these events and battle with these elites, though, you will have to qualify in smaller competitions, first. Google even hosts their own CTF competitions with prize money in the thousands of dollars.
