FortID 2026
This is the fourth global CTF organized by employees of Blockhouse Technology Zagreb (tbtl.com).
It is also the second incarnation under our brand name - Fort ID (https://fortid.com/) - a privacy-first, secure, and eIDAS 2.0 compliant digital identity solution.
The contest will be in the Jeopardy format, featuring all of the standard categories (web, crypto, rev, pwn, misc, OSINT).
We will have a wide range of challenges, from beginner-friendly ones, all the way to some spicy ones which should hopefully be interesting to seasoned players as well.
