Experts Stress Better Election Security Following DefCon Report

There has been a lot of rumor and speculation about the 2016 U.S. presidential election and the possibility that the results were manipulated or hacked in some way. While investigations continue and there is no hard evidence I am aware of that any succ… Continue reading Experts Stress Better Election Security Following DefCon Report

Inside This Year’s Queercon Badge

At this point, it’s not really correct to describe DEF CON as a single, gigantic conference for security, tech, and other ‘hacky’ activities. DEF CON is more of a collection of groups hosting villages, get-togethers, meetups, and parties where like-minded individuals share their time, company, electronic war stories, and whiskey. One of the largest groups measured by the number of rideable, inflatable unicorns is Queercon, a ‘conference within a conference’ dedicated to LGBT causes, a rager of a party, and a killer conference badge.

The Queercon badge is always a work of art, and this year is no exception. Last …read more

All the Hardware Badges of DEF CON 25

Hardware is the future. There is no better proof of this than the hardware clans that have grown up around DEF CON, which in recent years has become known as Badgelife. I was first drawn to the custom hardware badges of the Whiskey Pirates at DC22 back in 2014. Hardware badges were being made by several groups at that time but that was mainly happening in isolation while this year the badge makers are in constant contact with each other.

A slack channel just for those working on their own DEF CON badges sprung up. This served as tech support, …read more

“Borrow” Payment Cards with NFC Proxy Hardware

Contactless payments are growing in popularity. Often the term will bring to mind the ability to pay by holding your phone over a reader, but the system can also use NFC tags embedded in credit cards, ID card, passports, and the like. NFC is a reasonably secure method of validating payments as it employs encryption and the functional distance between client and reader is in the tens of centimeters, and often much less. [Haoqi Shan] and the Unicorn team have reduced the security of the distance component by using a hardware proxy to relay NFC interactions over longer distances.

Michael Ossmann Pulls DSSS Out of Nowhere

[Michael Ossmann] spoke on Friday to a packed house in the wireless hacking village at DEF CON 25. There’s still a day and a half of talks remaining but it will be hard for anything to unseat his Reverse Engineering Direct Sequence Spread Spectrum (DSSS) talk as my favorite of the con.

DSSS is a technique used to transmit reliable data where low signal strength and high noise are likely. It’s used in GPS communications where the signal received from a satellite is often far too small for you to detect visually on a waterfall display. Yet we know that …read more

Injecting Code Into Mouse Firmware Should Be Your Next Hack

Here’s a DEF CON talk that uses tools you likely have and it should be your next hacking adventure. In their Saturday morning talk [Mark Williams] and [Rob Stanely] walked through the process of adding their own custom code to a gaming mouse. The process is a crash course in altering a stock firmware binary while still retaining the original functionality.

The jumping off point for their work is the esports industry. The scope of esporting events has blown up in recent years. The International 2016 tournament drew 17,000 attendees with 5 million watching online. The prize pool of $20 …read more

Sunday: Breakfast at DEF CON

Nurse your hangover by having Breakfast at DEF CON with Hackaday this Sunday. You’re invited to our yearly ritual by marking the beginning of the end with coffee and pastries at 10:30 am.

Choosing an exact location in advance is always tricky (anyone who’s been to DEF CON understands). We’ll pick a place once we hit town later this week. For now, head over to the Breakfast at DEF CON event page and hit the “join the team” button on the bottom left so we can let you know when we’ve found the perfect location for the breakfast meetup.

DEF CON Badgelife: Someone Finally Did It

Badgelife is the celebration of electronic conference badges, a way of life that involves spending far too much time handling the logistics of electronics manufacturing, and an awesome hashtag on Twitter. Badgelife isn’t a new thing; it’s been around for a few years, but every summer we see a massive uptick in the lead up to Def Con.

For the last few years, the designers and engineers deep into Badgelife have had the same conversation dozens of times. One person says, “you know, someone should build a badge that’s a quadcopter.” Another person replies, “Can you imagine how annoying that …read more
