Hackfest is the largest hacking event in Canada and brought together more than 1500 computer security enthusiasts in 2023. We are looking for more than 1800 in 2024. The event takes place over two days of technical conferences about security and hacking and 4 days of training which have been developed for Quebec and in French.
Both nights let participants measure their security and hacking skills in a unique Hackfest CTF Pro and Classic (Capture The Flag). The whole evening is accompanied by a lockpicking contest, DJ atmosphere, workshops, evening conferences, live podcast recording and more.
