Lifecycle
Badge ecosystems keep moving after handout: apps, hexpansions, SAOs, antennas, cases, repair parts, firmware updates, and post-event hardware experiments.
The same attendee report says each badge arrived with one pre-installed clue and could connect to other badges so participants could exchange clues while solving puzzles, ciphers, games, and hacks.
SourceThe same public source says participants could hack the badge and bypass the contest altogether.
SourceThe official controller-screen repository documents an ESP32 screen interface that controlled 2023 badge LEDs over BLE mesh, exposed debug/admin menu behavior, sent messages/popups, and used secure boot on competition boards.
SourceThe finalist writeup says each TISC@DEF CON SG finals participant was handed an ESP32 hardware trinket for one of the on-site challenges.
SourceThe writeup documents multiple clue texts triggered by toggling DIP switches and pressing a badge button, turning a small hardware input surface into the puzzle selector.
SourceThe write-up documents special Commander badges used by SAINTCON Committee members to help Agent rings progress through later challenge stages.
SourceDatko says Matt Lorimer found one of the SAINTCON secrets by examining the badge source code, tying the badge to the Hacker Challenge trail.
SourceThe recovered wrap-up states that the badge contained secrets, but no public challenge archive or firmware source was recovered in this pass.
SourceSecOps directs badge participants to Vulnmachines to solve the badge hacking challenge and receive the binary codes needed to unlock the badge.
SourceHackers Challenge, Tamper Evident, Scavenger Hunt, Vault Badge, and HACK-IN-THE-BOX entries preserve reward paths tied to game masters, contest completion, enough collected items, or event participation.
SourceThe guide includes Hackers Challenge, HACK-letter, Scavenger Hunt, and other game-adjacent MiniBadges with acquisition paths tied to game masters, challenge completion, or BadgeLife community interaction.
SourceThe badge CTF is framed as an airship journey with touch-key and serial navigation, games, riddles, and harder crypto, reverse-engineering, and memory-corruption challenges.
SourceThe badge CTF uses a serial monitor at 9600 baud; sending three stars enters CTF mode and solving eight cryptography puzzles unlocks eight building lights.
SourceThe badge presents itself as both HID and serial; HID button output gives onboarding and clues, while listening on the serial interface reveals the path into the PGP/key-recovery challenge.
SourceThe guide documents a serial CTF menu with visual hardware debugging, reverse engineering, RF hacking, and crypto protection categories.
SourceThe same official note connects the badge context to network challenges, simulated IPv6 workstations, an RF monitoring station, and a provided smartcard.
SourceThe Basic Edition firmware was documented with CTF tasks started through serial terminal utilities, and the public CTF repository preserves eight post-event challenge write-up areas.
SourceThe Virtualabs repository preserves Python console tooling and serial interaction material for working with the badge challenge.
SourceThe official volunteer page lists welcoming participants, distributing badges and goodies, and orienting visitors among the conference rooms.
SourceThe badge challenge used six lanyards carrying Lewis Carroll Nyctograph symbols and Poe Gold Bug cipher material that translated into early-stage secret messages.
SourceNicolai Electronics presents Tanmatsu as a preassembled, out-of-the-box handheld derived from the Konsool open-design community hardware project.
SourceThe communicator add-on is documented as part of the 2024 badge ecosystem.
SourceThe teardown documents 115200-baud serial output, BLE-readable messages, hash clues, and firmware strings analyzed with Ghidra.
SourceThe curated Hackaday.io list preserved attendee-built cases, Atari and Apple-like emulators, games, music, QR generation, Morse code, Bluetooth chat, and plotter firmware hacks.
SourceThe thread clarifies that the forum badge was a separate extra badge for forum-member recognition, not a sticker or overlay for the official DEF CON badge.
SourceKonrad Beckmann's README-listed project used the RP2040 game badge as a video player and AM radio transmitter.
SourceThe 2023 data export includes event and community entries such as RFID Rocket, Minibadge Community Badge, LAN Party, Hardware Hacking, Fox Hunt, The Keep, and Hallway Talks.
SourceJens 'JWolf' Larsen's README-listed adventure game preserved the Game On badge as a homebrew handheld target.
SourcePieter Vander Vennet's README-listed Flappybirds project appears in the BornHack 2022 badge project list.
SourceGlymphie's README-listed Pacman project is one of the preserved homebrew examples for the Game On badge.
SourceDaniel Lundsgaard Skovenborg's README-listed Survivator arcade game used a micro:bit for controls.
SourceHackin7's preorder post offered the HFSDR badge for collection at DEFCON SG, with battery and no-battery kit pricing and possible later handoff at Hackaday Europe or DEFCON US.
SourceHackaday documented thousands of custom DEF CON 25 hardware badges, a badge-maker meetup, and shared API work among makers, making the simple official badge historically important by contrast.
SourceCommunity ROM work showed the badge running custom Game Boy ROM code and controlling all nine LEDs beyond the default controls.
SourceThe r4venOS community firmware replaces the Pacman firmware with a WiFi scanner, evil-twin detector, deauth, and crypto utility toolkit on the same ESP32 hardware.
SourceThe community Meshtastic guide maps the badge to a PlatformIO ekoBadge environment with RFM95, OLED, three NeoPixels, keyboard buttons, and speaker pins.
SourceThe guide lists AppSec, Circuit Assembly, Hardware Hacking, Healthcare, HomeLabs, IoT, Lockpicking, RFID/NFC, Scavenger Hunt, SMD Challenge, and Learn 2 Solder style badges acquired through community areas, booths, challenges, or presentations.
SourceThe official page documents Red Team Community, RFID/NFC, Hardware Community, Lock Picking, Tin Foil Hat Talks, and related MiniBadges with acquisition tied to community events or interaction.
SourceThe BIC Pick page says the badge can be spotted on village volunteers, leaders, and supporters throughout the con.
SourceA community Arduino nofrendo port ran NES games on the Fri3D 2022 badge with display output, buzzer audio, ROM loading from SPIFFS, and a documented START-button workaround.
SourceThe same project archive includes a backpack-mounted open access point and four-matrix scoreboard that counted unique connecting clients during the conference.
SourceOfficial attachment pages preserve first, second, and third-place ACFT badge-art variants for the 2021 set.
SourceThe ICFT player OP2 attachment page preserves a distinct ICFT player badge-art variant in the 2021 set.
