        Eckbox is software designed to aid in a specific type of
        security testing against a spying attack known as van Eck
        Phreaking or TEMPEST. It involves picking up radiation leaking
        from an electronic device, such as a monitor, and interpreting
        the signal to recreate the data contained in the device. This
        can be thought of as a sort of shoulder-surfing. Eckbox is the
        first and only open-source software designed that helps to test
        against this kind of attack (and might I point out that a van
        Eck Phreaking attack is far easier, less time consuming, and
        less costly than trying to dictionary or brute force almost any
        encryption).
...
        Eckbox is a program that interprets information input from a van
        Eck Phreaking device (see hardware page), to find out what image
        is displayed on a target monitor remotely. Think a cross between
        a wiretap and shoulder surfing. This is so that you, the
        security phreak, can find out what works best to keep this
        attack from being used on you. If you want more info on van Eck
        Phreaking, I suggest whatis.com, because I don't feel like
        reiterating everything they've already said.
...
        This is where I explain how to build the hardware necessary to
        utilize the eckbox software. Don't worry, I built mine in less
        than $30.

        Ok, so at this point, you have data going into your radio, from
        the radio to your ADC, and out to the parallel port. Next, we
        just need to tune the radio, and get some power running to it
        and your ADC. I'm sure you can figure out the radio on your own,
        and by examining the docs on your ADC, you can figure that out
        too. On the tuning, tune your radio to the highest frequency of
        FM that it can go that does NOT have a station. If you have
        tuned it right, it will be at about 108 MHz (roughly), and white
        noise will be coming from its speakers. After this, you're done.
        Just put the radio next to the target monitor and run Eckbox,
        and it will display (roughly) the image displayed on the target
        monitor. woot for you.
