The iCTF 2025-2026 will take place from 9 March 2026, at 10 am Pacific Time, until 13 March 2026, at 4pm Pacific Time. iCTF was originally scheduled for the beginning of December 2025. Due to unforeseen circumstances, we had to postpone it.
As it was for the 2023 and 2024 editions of the iCTF, there will be two separate competitions: one dedicated to high school teams (hiCTF) and one for college undergraduate students (uniCTF). Both competitions will be challenge-based. They will also incorporate themes around Artificial Intelligence and agents.
iCTF 2025 will be sponsored by the ACTION AI Institute and will be organized and run by WiCS and Shellphish.
Teams can practice using the challenges from the 2023 and 2024 editions of the competition.
Register your team of up to ten players using the form linked here. Note that an associated faculty/lecturer/teacher is required, as all teams will be vetted. An institution can have multiple, non-colluding teams.
This information is hot off the presses. We'll post more here as soon as it becomes available.
