Target John

Target John is a competition where participants receive several details about a real target and they have to find out information about that specific person or group.

During the competition, participants will face challenges from many cyber security fields such as forensic, penetration testing, networking but in the end, they will have to spy the target gathering as much information is possible, hijacking his account without any notice, backdoor his devices, getting pictures and so on.
