h-c0n
The February 5-7, 2026 Hackplayers h-c0n edition in Madrid, with workshops at Exe Madrid Norte and talks at Centro Cultural Sanchinarro, whose official post announced the CTF BADge electronic development-board challenge.
Centro Cultural Sanchinarro, Madrid · Spain · 2026
A source-backed Spanish hacker-conference electronic badge record: the official h-c0n post says Hackplayers finally produced an electronic badge for the sixth 2026 edition, describes it as a fully functional development board, and ties pickup to the February 6 conference registration and CTF start; the public `therealdreg/hcon2026hwctf` repository and Hackplayers post-event write-up document RP2350/RISC-V firmware, tooling, named co-creators, and winner write-ups.
Lifecycle
The official h-c0n badge post says the CTF BADge is a fully functional development board that can be used for personal projects, not only an ornament.
The official post says participants could start the CTF when registration opened on February 6, 2026 at 16:45, with the competition ending on February 13 at 17:00 or when three participants solved every flag.
The public hcon2026hwctf repository provides ctf.uf2 and describes RP2350/RISC-V Hazard3 exploitation challenges for the HC0N 2026 hardware CTF.
The Hackplayers recap links the first three winner write-ups and summarizes their approaches: firmware extraction, RISC-V reversing, logical-flaw exploitation, static and dynamic analysis, validation weaknesses, and state manipulation.
The repository preserves first, second, and third winner write-ups plus serial, picotool, BOOTSEL, and debugging guidance for people replaying the hardware CTF.
Operational history
The Spanish h-c0n record remains source-backed and image-free rather than copying blog images, repository photos, prize photos, screenshots, logos, or generated badge art.
The catalogue records only the official development-board, Hackplayers recap, and repository-backed RP2350/RISC-V challenge claims while withholding exact board-design and manufacturing claims.
The record distinguishes the conference CTF BADge from compatible at-home replay boards and preserves the hardware-debugging requirement without overstating universal compatibility.
