DEF CON 34 is scheduled to take place from August 6 to August 9, 2026, in Las Vegas, Nevada. The event will be hosted at the Las Vegas Convention Center (LVCC), specifically within the West Hall, marking a continuation of the conference's expansion into premier, high-capacity venues. This 34th iteration of the world's most renowned hacking conference centers around the theme of "Agency," focusing on individual self-determination in an increasingly complex technological landscape.

As the cornerstone of the annual "Hacker Summer Camp," DEF CON 34 follows Black Hat USA 2026 and runs alongside BSides Las Vegas, creating a week-long convergence of cybersecurity professionals, independent researchers, and hardware enthusiasts. The selection of the West Hall at the LVCC provides the necessary infrastructure for the massive scale of contemporary hacker villages, Capture the Flag (CTF) arenas, and demo labs that define the DEF CON experience.

The Theme of Agency in 2026

The chosen theme for DEF CON 34 is "Agency." This concept addresses the critical intersection of technology and human autonomy. In an era dominated by automated algorithms, pervasive telemetry, and black-box systems, "Agency" represents the hacker’s ability to understand, manipulate, and reclaim control over the tools and platforms that shape daily life.

The focus is on self-determination: charting a personal course through technology and actively supporting systems that align with individual values rather than corporate or institutional mandates. At DEF CON 34, this theme will manifest through talks and workshops that challenge the status quo of "user" passivity. It encourages participants to look beyond the interfaces provided to them and investigate the underlying logic, thereby exercising agency through technical mastery.

Venue Infrastructure: The Las Vegas Convention Center West Hall

The transition to the Las Vegas Convention Center West Hall is a strategic move to accommodate the growing attendance, which is expected to exceed 30,000 participants in 2026. Located at 3150 Paradise Rd, the West Hall is one of the most technologically advanced exhibition spaces in the United States.

Technological Capabilities and Layout

The West Hall offers over 1.4 million square feet of space, featuring advanced audiovisual capabilities, high-density Wi-Fi infrastructure, and climate control systems capable of handling the intense Las Vegas August heat. For DEF CON 34, this space will be partitioned into several key zones:

  • The Main Stages: Large-scale presentation halls for the marquee talks and "Track 1" sessions.
  • The Villages: Dedicated areas for specialized sub-communities, such as the Aerospace Village, IoT Village, and the ICS (Industrial Control Systems) Village.
  • The Contest Area: A centralized hub for the flagship CTF and various hardware/software challenges.
  • Vendor and Exhibitor Hall: A space for cybersecurity companies, tool makers, and non-profit organizations to showcase hardware and software.

Transportation and Access

Accessing the West Hall is facilitated by the Las Vegas Monorail, which has a dedicated station (Boingo Station) at the Convention Center. This allows attendees to travel efficiently from major hotels on the Las Vegas Strip to the venue. Additionally, the LVCC Loop, an underground tunnel system utilizing Tesla vehicles, provides rapid transit across the massive convention center campus, connecting the West Hall to the Central and South Halls.

Hacker Summer Camp 2026: The Global Context

DEF CON 34 is the culminating event of "Hacker Summer Camp," a period in early August when Las Vegas becomes the global center for information security.

Synergy with Black Hat and BSides

  • Black Hat USA 2026: Scheduled for August 1–6 at the Mandalay Bay Convention Center. This event leans toward professional training, briefings, and corporate security strategies. Many attendees transition directly from Black Hat to DEF CON.
  • BSides Las Vegas 2026: Running from August 3–5 at the Tuscany Suites & Casino. This community-driven conference offers a more intimate, grassroots environment that complements the larger scale of DEF CON.
  • AI4 2026: Running from August 4–6 at The Venetian. As the largest applied AI conference, its proximity to DEF CON 34 highlights the growing overlap between machine learning and offensive/defensive cybersecurity.

For professionals in the OT (Operational Technology) and ICS sectors, the first week of August 2026 represents the densest concentration of expertise, with specialized sessions occurring across all three major conferences.

The DEF CON 34 Electronic Badge: The SAO Platform

A significant highlight of DEF CON 34 is the return of the electronic badge. For the 2026 event, organizers have confirmed a "SAO Edition" (Simple Add-On) badge, designed to be a fully inspectable and modifiable hardware platform.

Hardware Specifications and SAO Standard

The badge is not merely an entry credential but a sophisticated piece of hardware hacking equipment. The 2026 design follows the SAO V2.0 standard, providing standardized headers for participants to attach their own custom-built "add-ons." These add-ons can range from simple LED displays to complex sensors, radio transceivers, or specialized cryptographic modules.

Organizers have released preliminary schematics and clearance measurements ahead of the event to allow the hardware community to begin prototyping their SAOs. The badge is described as an "iconic platform" that will remain functional and useful as a security tool long after the conference concludes. This aligns with the "Agency" theme by providing participants with a device they can truly own, understand, and improve.

Flagship Contests and Technical Challenges

DEF CON is renowned for its competitive atmosphere, and DEF CON 34 will feature some of the most rigorous technical challenges in the conference's history.

The Capture The Flag (CTF) Revolution

The DEF CON CTF is widely considered the world championship of hacking. In 2026, the contest will be organized by a new team: the Benevolent Bureau of Birds (BBB). This group takes over the mantle from previous legendary organizers like the Order of the Overflow and the Nautilus Institute.

A key shift for the 2026 CTF is the integration of "agentic tools." Following the trends observed in 2025, where automated AI agents began successfully completing complex challenges, the 2026 arena will likely see a hybrid of human ingenuity and autonomous scripts. The qualifier rounds are scheduled for late May 2026, setting the stage for the final showdown in the West Hall.

$unl1ght sh4d0w5: The Ni Rubi Challenge

One of the most anticipated specialized contests is the "$unl1ght sh4d0w5" challenge, which focuses on cyber-physical systems. Unlike traditional "black box" contests where systems are hidden, this challenge provides participants with a full blueprint and a production-ready Linux system.

  • Phase 1: Shadows Recon: Contestants must extend provided exploit chains to deliver a malicious payload on a known system.
  • Phase 2: $unl1ght Horizon: The system returns with hardened defensive technology, requiring contestants to adapt their exploits in real-time.
  • This contest offers a significant $10,000 prize for the first participant to complete both phases, emphasizing the shift toward securing (and breaking) industrial and physical infrastructures.

Payment Hacking and Vending Machine CTFs

Other notable contests include a dedicated payment hacking challenge, covering everything from magstripes and NFC wallets to ATM forensics and API manipulation. Additionally, the "5n4ck3y" project returns—a retro snack vending machine converted into a network-connected CTF badge dispenser. These contests require a mix of hardware hacking, social engineering, and reverse engineering.

Specialized Villages and Training Courses

The "Villages" at DEF CON 34 represent the decentralized heart of the event. Each village focuses on a specific niche within the security ecosystem.

Key Villages for 2026

  • ICS Village: Focusing on the security of power grids, water treatment plants, and manufacturing lines.
  • IoT Village: Addressing the vulnerabilities in connected consumer devices, from smart locks to medical equipment.
  • AI Village: Exploring the security of large language models (LLMs), prompt injection, and the use of AI in vulnerability discovery.
