The May 12-13, 2025 BSides Adelaide edition whose public Hackerware, Hackster, and attendee writeup sources document the second Wombat CTF badge with onboard binary-entry buttons and a secret hardware challenge.
Hilton Adelaide, South Australia · Australia · 2025
BSides Adelaide 2025's second Wombat badge is source-backed by Hackerware, Hackster, and attendee challenge analysis: it kept the MS51FB9AE/CR2032 LED badge line but added onboard CTF controls, seven official challenge LEDs, binary flag entry, and an unannounced hardware challenge.
Lifecycle
The Wombat-2 CTF presented seven official puzzles; each successful binary flag lit the matching progress LED on the badge.
The 2025 badge replaced USB-dependent input with onboard CTF, 1, and 0 tactile buttons for entering ten-bit challenge flags directly on the badge.
Creator and attendee writeups document a hidden challenge beneath the published CTF path, with PCB inspection and extra LED behavior rewarding hardware probing.
Operational history
The catalogue uses it to prove badge behavior and puzzle surfaces while avoiding full challenge-solution reproduction in the main badge summary.
The entry remains text-and-source only until a licensed original photo or upstream raster render is selected and documented.
The record keeps the hardware and software claims to creator and attendee documentation instead of inferring a full implementation.
