Hands-On Radio Hacking

CRASH member Samy recently gave a talk at Defcon about car/radio hacking and would like to do a more hands-on version at CRASH Space.

WHEN: Friday, Sept 18 8:00 – 10:00pm

Some topics we’ll go over and live demo as much as possible (legally, of course):

  • low-cost hardware and open source software for radio exploration (RTL-SDR, HackRF, CC1111EMK, IM-ME, etc)
  • sniffing and deciphering unknown radio signals
  • reverse engineering hardware (using logic analyzers, determining unmarked chips, etc)
  • wirelessly reverse engineering radio hardware (like cars and garages)
  • methods to attack and exploit radio communication (like unlocking cars and garages)
  • exploiting mobile device trust + exploiting mobile apps by performing SSL man-in-the-middle attacks, DNS spoofing, automated HTTPS injection/traffic manipulation
  • security measures to consider for more secure designs in the future

Samy will demonstrate all attacks from start to finish, and encourages you to bring any of the following low-cost hardware and go through the entire process with him:

  • $22 – RTL-SDR (hardware dongle for software defined radio, allows sniffing radio frequencies up to ~1.7GHz). This is a great buy and very powerful
  • If you’re comfortable with Arduino and coding, this $9 CC1101 radio (sub-GHz RF transceiver) goes well with an Arduino or Teensy and is very potent /li>
  • I would NOT suggest you buy this $75 CC1111EMK (basically the $9 chip above without a processor) because better/cheaper hardware is coming out soon, but we may use it for those who don’t want to build their own device (sub-GHz radio transceiver and MCU)/li>
  • Bring a logic analyzer if easy to and you have one — while I prefer Saleae, there are much more inexpensive ones out there, and you can even turn your Arduino or Teensy into a low-speed logic analyzer/li>

Also, you’re welcome to bring:

  • your own devices that sniff or emit radio (such as garage door openers, car keys, etc) and inspect them live! (It’s okay if you don’t want to, as Samy will bring a bunch of his own that you can hack.)
  • snacks and drinks
  • smiles
  • laptop
  • anything else you want, really

Hope to see you there!

MakerBar to host new Software Defined Radio Night Friday, June 13, 2014


‘We interrupt this broadcast transmission to bring you special breaking news report… live from Hoboken, MakerBar….’

Join us as we explorer the air waves with Software Defined Radio(SDR)… Doors Open at 7PM..  Also we will be running our OPEN CRAFT NIGHT as well. Bring a project, in any shape or form, hack the night away with us….

Or just come by explore the space, have a beer with us and see what creations are developing in the MakerBar community…..

The Gentle(wo)man Hacker’s RC Airplane

If you’re like me, the RC aviation hobby is as fascinating as it is costly.  In the two videos below that we produced for element14 though, we cover how to convert a $10 foam glider into a great training flier and then get even more bleeding edge with a cheap-but-good-for-the-price setup for flying UAV style with a pistol grip camcorder mounted to the plane that transmits to a screen on the ground.  Dan Meyer with the help of Ken Zinnen walk you through some of the many exciting  facets of radio controlled airplanes.
