Each year, HITCON CTF uses the acronym "CTF" as inspiration to create different thematic concepts. From the early "Capture The Food" with a food-based theme, to last year's "Capture The Fengshui" themed around feng shui, this year HITCON teams up with Cyber Range to bring a cyberpunk-themed event. Stay tuned to see what unique "CTF" style will unfold on site this year.
