DEFCON 22 vendors: Tesla, Blackphone and more

America's biggest hacker conference is setting a new record for attendance at its 22nd annual event, at the Rio Hotel and Casino, Las Vegas, Nevada -- and its vendors reflect the event's growth.

This year's vendor floor was wall-to-wall attendees and packed with hardware and schwag, PR booths and artists. All vendors are doing record sales, and the busiest exhibitor is an unnanounced guest: Tesla Motors.

DEFCON 22 continues now through August 10.

Billing itself as "the world's first smartphone to put privacy and control ahead of everything else" and celebrity endorsed by FOX News personality Sean Hannity, Blackphone is for sale on the floor -- cash only.

All manner of antennae are available (and seen in use around the conference) from SimpleWifi.com.

The DEFCON Keyport Slide, basically a Swiaa Army Knife keychain update, was one of the few booths with a pro display but slightly lukewarm reception -- though this was only day one.

Ghostery -- one of the most popular web tracker-blockers -- made its first appearance on the DEFCON vendor floor, not selling anything but simply talking about its service and connecting with the DEFCON community.

Tesla Motors has the busiest exhibit, and welcomes everyone to touch, sit in, and play with the display car. Tesla's security team staffed the exhibit and has been answering questions nonstop.

A constant presence at DEFCON, the Electronic Frontier Foundation was on hand with new shirts, stickers, and privacy rights information.

UNIX Surplus is in high demand, but the exhausted staff still have time for smiles.

Popular hacking webshow HAK5 has a giant piece of DEFCON vendor floor real estate and are impossible to miss amidst the crowds.

On display: HAK5's WiFi Pineapple, merged with a drone.

Back with its punk rock attitude and lots of cool, cheap stickers, Unamerican is another very busy booth.

The happy campers from Metasploit pentesting software are selling t-shirts to raise money for the EFF.

As seen every year at DEFCON, Hack Naked (Security Weekly Podcast) isn't what it seems at first glance.

If you need bump keys, lockpicks, or anything related to picking locks, as usual, there are at least half a dozen tables vying for your hard earned cash.

A giant display of a Medeco lock shows those not in the know exactly how this kind of lock works -- and how easily it can be picked.

Security Snobs has high-end Abloy locks on display.

Even last year's DEFCON gear is for sale -- and at the rate of the teeming crowds, won't be left at the end of the conference.

Need a lockpicking mug? Take your pick -- no pun intended -- from the table after table of every kind of hacker merchandise imaginable.

DEFCON 22 continues through August 10 at the Rio Hotel and Casino, Las Vegas, Nevada.
