ZeroDays CTF 2019
ZeroDays CTF is one of the best-known competitions in Ireland, as well as one of the largest in-person capture the flag events in the world.
This CTF was based around horror movies. All challenges were based around the theme of horror movies and had challenges that included Physical, Forensics, Exploitation, and more types of challenges.
One of my favorite challenges from this CTF was an OSINT challenge in which you had to get the GPS location of a street sign from google earth on along a Highway in Ireland. This challenge was tough not because of trying to locate the sign, but because the network during the event was not as good as it could have been causing the network to collapse regularly, and being that the event was underground it meant that much of communications were cut off when the network went down
it still ended as a fun competition
