Hackable electronic CTF badge with a source-depth caveat
A conservative PWNEDCR 0x08 record: a named post-event account says the October 18-19, 2025 San José conference used a hackable electronic badge as part of its CTF, with hidden Easter eggs and challenges. It supports the reality of a physical electronic badge but publishes no component, firmware, maker, production, or reusable-image documentation.
People
The named post-event account describes PWNEDCR as a volunteer-run conference organized by DC11506. This records that narrow report-level community role without inferring individual badge authorship, hardware or firmware responsibility, production, legal identity, current organizer status, or image-reuse authority.
SourceIt adds a Costa Rican event badge to the worldwide compendium while keeping the source boundary visible: post-event artifact testimony proves a badge, not a complete technical archive.
A named post-event account calls the lanyard-worn object an electronic badge and says at least three people had already hacked it during the CTF. It identifies no MCU, board revision, display, LEDs, radio, power system, connector, sensor, schematic, BOM, fabrication file, or other hardware detail.
The report describes a hackable badge with hidden Easter eggs and challenges integral to the CTF. It does not identify firmware, source code, binary, protocol, app, toolchain, license, update workflow, or a reproducible software path.
The same post-event account places PWNEDCR 0x08 at Auditorio Nacional in San José on October 18-19, 2025. The live official PWNEDCR home has since rolled to 0x9 and does not retain a public 0x08 badge archive.
Lifecycle
The report places PWNEDCR 0x08 at Auditorio Nacional in the Centro Costarricense de Ciencia y Cultura in San José, Costa Rica on October 18-19, 2025, with three simultaneous tracks and more than 650 attendees. That event context does not identify badge quantity, eligibility, registration tier, price, pickup, delivery, admission role, or universal attendee distribution.
SourceThe report says the electronic badge was hackable, had already been hacked by at least three people during the CTF, and contained hidden Easter eggs and challenges integral to that competition. It does not describe the challenge design, interfaces, exploitation path, firmware, scoring, data handling, or any completed participant outcome.
SourceOperational history
The badge is not presented as an admission credential, universal attendee entitlement, complete CTF platform, or verified distribution record.
The catalogue deliberately stops at source-described electronic and interactive behavior rather than inventing a technical architecture or user workflow.
The record remains source-backed and image-free rather than copying generic stock art, event graphics, screenshots, social media, placeholders, or generated approximations.
The dossier treats that report as enough to establish a real 2025 electronic badge without representing it as an official 0x08 archive or independent technical corroboration.
