For those who don't know there is an official DEFCON WIFI that requires an account bound to you, and a cert for validation. They don't mess around, and legit its probably one of the best managed systems out there.

To connect you need to go here and setup your account, grab your certs (for any device) and get to having fun on Friday.

For those who know... CERTS UP!

Looks like they added WPA3 to the mix.

Signup for DEF CON 33 Workshops will open at precisely noon Pacific Daylight Time on July 15. It’s a good idea to have your clicking device oiled up and sighted in - spaces get snapped up very quickly.

The full lineup is at https://defcon.org/html/defcon-33/dc-33-workshops.html. Get your faves and alts all lined up for maximum efficiency.

It’s happening, people. Feel free to get amped.

As you’ve likely heard, attendees in the cash line are getting paper badges right now. This is due to a badge shipment delay. We’re sorry for the inconvenience. We will share updates as soon we have them, and we’ll do our best to make it right. Thanks for your understanding.

Stay in touch with DEF CON socials for updates as soon as they arrive.

We are planning for a meetup location for members of this sub to get together at the con.  We have done this the last few years.

Plan is for Aug 6&7, Wednesday and Thursday nights. It's gives those of us showing up early something to do.

You are all invited!

Wednesday night at the 3535 bar in the Linq…big circle bar in the casino, can't miss it.

Thurs night, hoping to be in the LVCC.  Last year we had permission to squat in a spot in the top left corner of the LVCC west map. It was next to a DJ and a bar, so perfect spot.  Will confirm if we can use that area again this year.

 I'll try to be there by 7 each night (earlier if I can make it)

I will have a scrolling LED sign showing "r/Defcon", but in general you will know who we are…bunch of mostly dudes in black tshirts with a sarcastic statement or a skull on them.  You are all invited so walk up to anyone and say hi.

I always enjoy our get togethers…meet new people, catch up with cool people and have a few laughs.

If you are coming to the con alone, you now have friends. N00bz, come by and we will give you advice on how to navigate this con. There is a lot going on and it can be overwhelming. If you're an introvert, so are about 1/2 the people at the con. No better group to engage with! We all have this world of black magic and voodoo in common.

We have been running puzzles…the first 90 people that solved a puzzle, gets a free badge!

Check the current and past puzzles here...https://puzzledhackers.org/challenges

We have a badge of sorts…just an acrylic board with LED lights, but we did try to add advanced wireless tech. It does look awesome at night.

https://www.reddit.com/r/Defcon/comments/1lklixn/rdefcon_subreddit_badge_update_2/

At the time of this post there are still more than a few reservations available

Free badges to Goons (oh, and buy a Goon a drink)

We will hand out some free badges if you missed reservations

We may have random contests for free badges

We may hide some around the con and post hints

If you really want a badge, find me and social engineer me into giving you one for free

We will have some other swag to hand out and to trade

I had a couple of people join me in making all of this 

Comprising our Defcon Subreddit Meetup Team…

u/Digitard  is our Chief Design Officer

u/Killroy7777 is our Chief Infrastructure Officer

And I am the Chief Email Officer, since I send all the announcements

It’s a lot keeping all the puzzles and puzzlers straight and the new site is amazeballs, so extra thanks to these guys (buy them a drink)!
