💡 Insider Tips: How to Get the Most Out of DEF CON 33

Arrive Early for Popular Talks – The best talks fill up FAST. If you see a session with a title like "New Techniques for Exploiting [Insert Major Software Here]", expect a line out the door.

Cash is King (No Credit Cards!) – DEF CON only accepts cash at the door for registration, and many vendors operate the same way. Bring enough to cover your needs.

Expect No Privacy (Yes, Really) – Your phone, laptop, and personal data are ALL fair game at DEF CON. If you bring a device, assume it’s already hacked. Many attendees carry burner phones and use fresh laptops just for the event.

Dress However You Want—But Be Ready to Blend In – Unlike other industry conferences, DEF CON is informal. Hoodies, jeans, and hacker-themed T-shirts are the norm.

Use Signal & A VPN – If you must use Wi-Fi, use a VPN. Otherwise, your data is probably already in someone else’s hands.

Check Out the DEF CON Parties & Meetups – Some of the best networking happens after hours, at unofficial meetups and events. Follow the DEF CON Twitter/X page for real-time updates.

🎟️ Registration & Where to Stay

DEF CON doesn’t do pre-registration online—it’s cash only at the door. Prices are usually around $360, but bring extra in case you want to buy merch or attend offsite events.

🏨 Hotel Recommendations

DEF CON partners with several Las Vegas hotels to provide discounted rates. These include:

  • The Flamingo (Budget-friendly, close to the conference)

  • The LINQ (Mid-range, modern, decent Wi-Fi security)

  • The Venetian & Palazzo (Luxury, premium experience, hacker-proof safes in rooms)

Rooms sell out fast during DEF CON, so book ASAP.

🤝 Networking & Community: How to Make the Most of Your Time

One of the best parts of DEF CON? Meeting like-minded people. Unlike corporate cybersecurity events, DEF CON has a strong DIY hacker ethos—meaning you can literally strike up a conversation with an elite hacker, a government security analyst, or a digital activist over coffee.

🔹 Go to the Villages & Strike Up Conversations – This is where real knowledge-sharing happens.
🔹
Join the DEF CON Forums & Discords Beforehand – Get involved with discussions before the event to meet people in advance.
🔹
Bring Business Cards (Yes, Even at DEF CON) – If you’re looking to network or recruit talent, cards still work—just make them untraceable (many people use alias emails).
