Defcon 2015

2 minutes, 33 seconds

Another year, another Defcon!  This was my third year attending.  The biggest change this year was that the conference changed locations moving from the Rio to Paris/Ballys.  Given I’m some what of a lookie loo I can’t say with super authority, but I thought the space worked as well as the prior location, leave the fact that the sky talks were on a separate floor and might have gotten less traffic.  Given that in prior years they had an hours long wait, it may have been a good thing.

Since I live in Vegas, I didn’t have any concerns getting my pick there, like I did with Hope. Otherwise, this years highlights were:

  • Seeing Cory Doctorow speak on general purpose computers.  Nothing really new here if you follow him (author ID 1!), but it was fun to see it all wrapped up nice and dense and delivered with passion.
  • Bruce Schneier is just awesome.  His talk was actually just 45 minutes straight of Q&A, but with a super nerdy crowd, it did not disappoint. Like Doctorow there was nothing new, but I found Schneier more pleasing and inspiring to see than Doctorow.
  • Holy crap Marc Rogers and Kevin Mahaffey, the Tesla hack guys, are awesome!  They literally tore into a new Tesla and gained remote root.  An amazing talk that was just high level enough to keep you following along but way deep enough to blow you away with how hard they had to work to achieve the hack.
  • Samy Kamkar‘s talk on hacking garage doors and car fobs was tons of fun.  I’d seen a video on the garage door opener before, but the fob attack was new; both were great to see revealed real time.
  • The EFF presented on their Lets Encrypt certificate authority which will feature automated cert creation and installation.  The demo was inspiring to see.  The thought of TLS for everyone and their mother is totally great.
  • I heckled Alejandro Mayorkas trying to force him to agree that crypto back doors are a Bad Thing.  Unsurprisingly, he didn’t take the bait. I was bummed that his security entourage was too strong to let me shake his hand and thank him for speaking at Defcon.

Though I didn’t make it very far through the matasano crypto challenges, it is amazing to see how relevant the lessons learned in those challenges are. Hex, Base64 and XOR…every talk I attended had one of these concepts as a critical part of their hack.

Here’s a list of talks I attended:
