Why It Mattered

It adds a fresh Southern California Security BSides electronic-badge record to the worldwide compendium and preserves a primary official field guide while the challenge page is live, without copying its copyrighted Google Sites imagery.

Hardware

The official badge-challenge page identifies the badge as a Cyberpunk Bunny PCB powered by an ESP32, with onboard accelerometer shake input, D-pad buttons, bunny-eye lighting, BLE behavior, and enough onboard logic to run challenge modes. It does not publish schematic, BOM, PCB files, battery details, production count, firmware source, or exact ESP32 module revision.

Software & Apps

The official guide describes a portable CTF with a 10 percent chance of a mystery encrypted message after shaking, D-pad selection for decryption methods, Basic Tier classic ciphers, Advanced Tier Base32, XOR, AES-128, and ChaCha20 challenges, Bluetooth LE co-op interaction with nearby attendees, and a hidden shaking-sequence Easter egg for an ultimate flag.

Lore

The event page brands the 2026 edition as America's Finest BSides, while the FAQ places it at San Diego State University's Montezuma Hall and Theater. The badge page says Electronic Cats would be in the Villages for badge questions or help.

Issues & Camp Impact

missing rights-cleared image note

No BSides San Diego 2026 Cyberpunk Bunny badge image is published because the official Google Sites page media and thumbnail do not provide explicit reusable image rights, attribution, and processing provenance for catalogue publication.

The entry remains source-backed and image-free rather than copying official site imagery, screenshots, social media, or generated visuals.

technical-source gap note

The official badge guide proves an ESP32-powered Cyberpunk Bunny portable CTF with accelerometer, crypto challenges, BLE co-op behavior, and hidden flag path, but no schematic, BOM, PCB files, firmware source, exact module revision, battery details, or production count were recovered.

The catalogue records verified badge behavior without inventing component-level electronics, source-release status, or shipped-hardware internals.
