In-Depth Review TG4G Review ·2026-06-25 · For reference only

What It Is

0day.net actually points to the official website of DEF CON, the world's top hacking and cybersecurity conference. Originating in 1993, DEF CON is the oldest, largest, and most influential offline hacker community gathering in the world. Its main conference is held annually in Las Vegas, USA, and in recent years it has gradually expanded to hold regional events in the Middle East, Singapore and other locations. This website is responsible for releasing the latest conference updates, opening registration, and archiving content from all previous years.

Core Features & Pricing

Core features include releasing conference agendas and hotel information, opening attendee ticket registration, calling for presentations, trainers and event submissions, providing archived downloads of videos and materials from all past DEF CON talks, offering access to supporting community forums and local user groups, and providing visa invitation letter application services for international attendees. Tickets use a tiered pricing model: for DEF CON 34, early-bird tickets cost $560 total, rising incrementally to $600 for regular-late tickets, and on-site registration costs $520.

Pros & Cons

On the plus side, as the birthplace of global hacker culture, DEF CON covers cutting-edge security research, hardware hacking, and practical cybersecurity work, with content expertise that ranks among the very best in the industry. It also makes all content from every past conference available for free to users worldwide, has an inclusive and open community that supports attendees organizing their own特色 events, and retains a strong authentic hacker culture identity. The downsides are that the main conference is permanently held in Las Vegas USA, so the time and financial cost of attending for domestic Chinese users is extremely high. All official content is in English with no Chinese localization support, and popular discounted hotel rooms sell out very quickly and require booking far in advance.

Target Audience & Access from China

It is suitable for attendance by cybersecurity practitioners, security researchers, experienced hacking enthusiasts, and cybersecurity vendors. Casual security enthusiasts can also access all past conference materials for free to learn. Direct access from China is unstable, and a proxy is usually required to browse smoothly.
