HITCON CTF 2025
HITCON CTF is a cybersecurity attack-and-defense competition organized by the Hacks in Taiwan Conference (HITCON). It can be described as a martial arts tournament for hackers. The challenge creators design problems across various cybersecurity skill categories—including Web, Crypto, Reverse Engineering, Pwnable, and Miscellaneous—to test the participants' abilities. HITCON CTF is not only a fierce competition among hackers, but also a top-tier showdown between the challenge creators and the competitors.
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.
