### DEF CON

Shared publicly  -

In honor of the addition of the Internet of Things Village to the DC23 festivities, your #defconflashbackfriday is 'The Internet of Fails' from DEF CON 22. Mark Stanislav and Zach Lanier share with you a funny/disconcerting view of the glaring weaknesses in the IoT. Possible side effects of watching this talk include suspicion of all things unnecessarily 'connected' and persistent unwanted thoughts about living in a Faraday cage.

New Speaker's Corner post on defcon.org: CFP FAQ!

This is the home stretch for getting your talk submitted for DEF CON 23. The submission deadline is May 10.  If you still have unanswered questions about the process of submission or selection, Leah has created a pretty exhaustive and very useful FAQ on the matter at :

Here's his algorithm:

L1 = 1st detent, centered on a whole #, <11
L2 = 2nd detent, centered on a whole #, <11
R = single location on dial (whole or half) that has resistance (with shackle force just under getting into a detent)

1st # in combo: (ceil(R) + 5) % 40
2nd # in combo: n % 4 = (1st # % 4) + 2
3rd # in combo: (L1 or L2 + 10*n) % 4 = 1st # % 4
- prefer the one with more give

The method I knew (back in high school) for the 3rd # in combo was this:

Find all series of detents with same value %4 and increasing by 10. One of the series has 3 detents between numbers and 1 detent on a number; the latter is the 3rd # in the combo.

Then 1st %4 = 3rd %4 = (2nd %4) + 2, so 100 possible combinations to test.

This method for getting the 1st and 3rd much more quickly is new to me, at least. Anyone know an original source for the discovery?﻿

Call for Contests and Events is open!

We know you have ideas. We know you’ve walked the floor at DEF CON and thought, “I know what kind of contest or event this place needs. One day I’m gonna get MY idea for Roomba Thunderdome to DEF CON and rule this place."

That one day is today (but not if your idea is Roomba Thunderdome - that’s mine). It’s time to take your great idea for a DEF CON contest or event and submit it to us. If it’s good enough, and you get it submitted by May 30, you may get to see your idea become a glittering Las Vegas reality.

The information you need to manifest your brilliance has a Forum thread. Go there and make us proud.

The DEF CON 23 Call for Vendors is now open, so if you have a product or merchandise you want to put in front of thousands of hackers you should check out defconvendors.com . It’s all there – all the info, the vendor area layout and even a surprisingly thorough FAQ. As always, we run out of vendor space pretty fast, so it’s a good idea to get yourself registered as soon as you can. The early bird catches the worm, and the late bird has pallets stacked high with regret.
Don't be late bird.

Brand new addition to the DEF CON Villages this year - IoT Village! Lots of workshops on hacking off-the-shelf connected devices, live talks and even some contests.

There's also a CFP. If you have a good idea for a talk about the Internet of Things, you've got until May 26 to submit to them at the link below. Topics they're looking for include:

Raiding Internet of Things - Show us how secure (or insecure) IP enabled embedded systems are. Routers, network storage systems, cameras, HVAC systems, refrigerators, medical devices, smart cars, smart home technology, and TVs -- If it is IP enabled, we're interested.

IoT Device Management – Discuss best practices for deploying and building security into IoT devices.

Anything else awesome that involves IoT devices!

Our speaker selection elves have been hard at work, sifting through the proposals for DEF CON 23, and they have a Friday present for you. The first round of Speaker Selection is done!

Did you feel that? That’s DEF CON 23 getting REAL, people. August 6 is closer than it sounds.

The selections are available for your inspection on the DEF CON 23 website. More will be posted in the coming days, so check back from time to time. Also, if you have a talk you want to see on this list, you only have until May 10 to submit it to us. That is hella soon, so get on it!
