Over the past four years, Hackerdom (the organizer and developer of RuCTF) has collaborated closely with Hack in the Box conferences, hosting exciting Attack-Defence CTFs as part of their events. The upcoming conference will take place in August in Phuket, Thailand, and Hackerdom is once again organizing a grand CTF, offering participants the option to either join on-site in Phuket or play online! The competition is scheduled for August 24-25, with a break for the night, and teams of up to 5 people can participate. The top-performing teams will not only win cash prizes but also receive an invitation to the PRO CTF, slated for the spring of 2024 in the UAE. With interesting services, our cloud infrastructure handling all the hosting, and top teams from around the world as competitors, it's bound to be an exhilarating experience.
