Brought to you by Dreamhack Team, based on Theori, Korea.
Dreamhack CTF is held twice a month - Div.1 at the beginning of the month, and Div.2 at the end of the month.
Unless stated, each Dreamhack CTF covers all categories in the CTF world, mainly pwnable/reversing/web/cryptography.
Results are reflected to the unique rating system in Dreamhack - some high-performing players are invited to our annual event, Dreamhack Invitational.
All challenges in the past CTFs are archived in the wargame page.
