NilbinSec DC34 Main Badge Fuzzer SAO
Independent ATtiny1614 DEF CON 34 badge-challenge fuzzer SAO
NilbinSec's public DC34 Main Badge Fuzzer SAO repository documents a standalone SAO designed to exercise interfaces on the official DEF CON 34 Human badge using information published before the conference. Its README describes three initial modes: GPIO1/GPIO2 stimulation on the left SAO port, an open-drain CPU wake assertion on GPIO4 of the right port, and an I²C-address listening sweep. The repository provides a KiCad schematic, BOM CSV, PCB archive, C firmware, and compiled hex/ELF files. The README explicitly warns that Mode 1 may harm the main badge and says a convention reflash might follow. This is source-backed pre-event independent challenge hardware, not proof of a finished run, sale, giveaway, pickup, compatibility with a final main-badge revision, authorization to probe another badge, official DEF CON issuance or admission, a reusable-image grant, or an explicit software/hardware licence.
