VuwCTF 2025

official repo

VuwCTF's largest event of the year! Competitors will solve challenges across seven categories: web, OSINT, reverse engineering, binary exploitation (pwn), cryptography, forensics, and misc. Prize eligible teams must consist of no more than three New Zealand secondary students for the secondary division, or three New Zealand tertiary (or secondary) students for the tertiary division.

For students in the Wellington region, we are running an in-person event in Cotton Building, Kelburn Campus. RSVP is essential: https://vuwctf.com/rsvp

We’re grateful for the support of Carapace (https://carapace.nz) and PentesterLab (https://pentesterlab.com/). The latter have provided one month of PentesterLab Pro to the members of the top two placing teams in both divisions.
