DEF CON 34 · United States · 2026
Documented independent pre-event ESP32 RFID-kit badge; distribution unverified
The public `slash128v6/DC34_Cnet_Badge` repository documents a DC34-named electronic kit titled “DC34 CompuNet Badge - Malware Scan Tool 3000.” Its README has a banner reading “Join CompuNet & Critical Start at Defcon!” and lists a PCB, ESP32 Dev Module, round LCD, RFID reader, microSD reader/card, RGB LED, six-pin female SAO header, four-AAA battery holder, 3D-printed stand and slides, RFID sticker tags, plus a separate RGB-LED SAO. The public project tree includes hardware, software, SD-card assets, and a root MIT license. It is therefore a real, independently documented pre-event DEF CON 34-associated kit record, not evidence that DEF CON, CompuNet, or Critical Start authorized, made, issued, sold, or distributed it.
People
The repository's root MIT License names slash128 as the 2025 copyright holder. This credits only the stated repository software/documentation role; it does not resolve the account holder's real-world identity or assign badge design, hardware manufacture, company affiliation, DEF CON authorization, distribution, event role, or image-rights authority.
SourceThe record preserves a technically specific current BadgeLife-style source tree without turning its company-oriented banner into a corporate or organizer attribution. It also keeps public project source, a named 2026 DEF CON association, and the absence of delivery evidence separate so the catalogue does not misclassify a planned kit as an official Human badge or a completed conference handout.
The README's kit inventory names a PCB, ESP32 Dev Module, round LCD display, RFID reader, microSD reader and card, slide switch, Schottky diode, RGB LED, six-pin female SAO header, battery holder with four AAA batteries, foam tape, 3D-printed stand, five 3D-printed slides, and five RFID sticker tags. It separately lists a companion SAO PCB with a six-pin male header and four RGB LEDs. The sources do not identify the ESP32 module variant, PCB revision, schematic, BOM, display or RFID part/protocol/frequency, SD interface, battery chemistry or power path, current limits, SAO version/pinout, safety validation, compliance, final assembly quality, or manufactured-unit parity.
The repository exposes an Arduino sketch area, an SD-card asset directory, and assembly/programming documentation; its root MIT license names `slash128` as the 2025 copyright holder for the repository software and documentation. The README describes an RFID-slide interaction that changes what is shown on the round display. It also refers readers to an ESP32 driver installer and third-party Arduino board/library dependencies, which are not treated as audited, redistributed, complete, event-installed, or license-covered firmware artifacts. No final event-unit firmware image, build manifest, source-to-unit hash, security review, or support/recovery commitment was recovered.
The project calls itself the Malware Scan Tool 3000 and frames its interaction as scanning the included slides or other RFID tags to show images, with additional images intended for sharing or trading. Its banner makes the Defcon, CompuNet, and Critical Start references visible in the project source, but the reviewed materials do not establish a formal company relationship, sponsorship, booth authorization, official DEF CON role, registration inclusion, admission function, actual handoff, or any post-event outcome. The 2026 event is still upcoming at this catalogue update.
Source-backed hardware metadata
Structured technical signals seeded from public badge documentation, repositories, schematics, firmware notes, or event evidence. These fields are designed for filtering, API use, repair planning, preservation, and future Companion Gear matching.
The public README names a DC34 electronic badge kit and lists a PCB, ESP32 Dev Module, display, RFID reader, storage, battery holder, and companion SAO; project distribution and authorization remain unverified.
Signal sourceThe public kit inventory names an ESP32 Dev Module but does not identify its exact variant, board revision, or final event-unit population.
Signal sourceThe README lists a six-pin female SAO header and a companion six-pin-male-header RGB SAO, without establishing an SAO version, pinout, electrical limits, or universal host compatibility.
Signal sourceThe README directs a USB-C connection to the supplied ESP32 Dev Module for a project workflow; it does not document a bespoke DC34 badge connector, USB configuration, or final-unit power design.
Signal sourceThe public kit inventory names a round LCD display; it does not identify the panel/controller model, resolution, or final unit parity.
Signal sourceThe public kit inventory lists a battery holder and four AAA batteries but does not document chemistry, power-path design, current limits, runtime, charging, or safety validation.
Signal sourceThe README identifies an Arduino sketch and Arduino-core/library workflow in the public project tree; this does not establish an audited, final, event-installed firmware image.

Lifecycle
The README separately lists a companion SAO PCB, a six-pin male header, and four RGB LEDs, then says its LEDs light when connected to the main badge's six-pin female header. It does not establish an SAO version, pinout, voltage/current limits, LED model, electrical protection, hot-plug behavior, compatibility with any other host, assembly quality, or final distribution.
SourceThe README says included slides or other RFID tags can be scanned to change what appears on the round display and mentions additional images intended for sharing or trading. It does not identify RFID frequency/protocol, tag type, reader configuration, stored content, data collection, authentication, access control, privacy practices, security properties, final gameplay rules, or a confirmed live event deployment.
SourceThe public README lists one PCB, ESP32 Dev Module, round LCD, RFID reader, microSD reader/card, slide switch, Schottky diode, RGB LED, six-pin female SAO header, battery holder, four AAA batteries, foam tape, stand, slides, and RFID sticker tags. It documents a project inventory, not a verified finished unit, component variants, electrical design, safe assembly/operation result, quantity, allocation, or completed event handoff.
SourceThe public project exposes Arduino-sketch, SD-card-asset, hardware, and license areas, while the root MIT license names slash128 for repository software/documentation. The README also refers to a driver installer and third-party Arduino board/library dependencies. This is a source-access record, not an endorsement, audit, binary provenance confirmation, build reproducibility result, final event firmware, support/recovery promise, or license statement for every bundled/external dependency.
SourceOperational history
The catalogue records public code and documentation without asking readers to run installers, treating the project title as a security claim, or representing the repository as a complete/audited/reproducible event-firmware release.
The record preserves the documented kit surface without converting it into an electrical specification, safe-build/use instruction, radio/RFID compatibility claim, battery-life estimate, or universal SAO-host guarantee.
The catalogue classifies the artifact as a planned independent DC34-associated badge kit rather than an official DEF CON badge, a company-issued item, an authorized event activation, an access credential, or a completed distribution.
The United States record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.
