    Emissions looks pretty interesing what singals flowing through the air
    generated from a LCD or other devices.

    I just realised I have a few of these digital tuners with one even in my
    pc. Unfortunately the newest Linux kernel does not like my chipset config
    for some reason and fixing it is more hassle than just getting a new pc.

    Nesta conferencia podemos ver o que se pode fazer com um simples receptor
    de televisão digital USB. Nos no MafraLab temos um… DEF CON 21 – Melissa

    This got me hooked on RTL SDR. If you don’t have a DVB-T dongle with an
    R820T tuner, go ahead and buy one! they are pretty cheap and the fun per
    dollar is insanely high. You have a huge part of the spectrum to explore
    and many fun things you can do like receive transmissions from satellites!
    You can find them for 9$ if you look.

    I think she needs to study what a clock signal is on a radio. Most of what
    she has shown are just clocks. Retrieving data in this way is nearly
    impossible (talking about hard drives) but tempest is still possible as
    keyboard sniffing and many other things. Even DSL is made of frequencies
    that can be easily intercepted.

    wish I could do this

    hmmm. she criticizes peoples C code.. nice talk

  12. scarlethideout says:

    Very interesting talk!

  13. Quatroking says:

    this talk is absolutely awful and unprepared

  14. Carol F. Milazzo says:

    This YouTube video of Veracode security researcher Melissa Elliott’s
    presentation at DEF CON 21 features SDR# and an RTL-SDR dongle receiver.

  15. Christopher Rabe says:

    Do not watch this video if you ever want to use technology again. Although,
    if your life long goal is to become a hermit living in a cave, go right on
    ahead.

    Also:)

    There’s a step up for the podium.

    Lovely presentation @abad1dea!

    I thought my military friend was full of shi*t, when he was talking about
    this a few years ago.

    GQRX, G, probably for Gnu. QRX is a ham radio aberration for ‘When will you
    call again?’. Or,’ I will call you again at (time)’. These are great toys
    to play with for receiving data from airplanes using ADSB, which transmits
    lat/long and other date. SDR# or SDR Sharp is the free software that
    receives ADSB. There is a RTL-SDR google+ group about these devices.

  22. RenateRoggen says:

    It’s not likely that the RTC (running at 32.768 kHz) is generating
    harmonics at 100 MHz. It’s probably that the display horizontal scan is
    running at 32 kHz. 32 kHz / 480 line = 67 Hz.

    you can even pick up a foreign radio with a guitar amplifier on a good day
