BSIDES CPT 2019 – Hacking satellites with Software Defined Radio (SDR) – Gerard de Jong

Published on May 14, 2022 by

Title: Hacking satellites with Software Defined Radio (SDR)

In this no holds barred down introduction to Software Defined Radio (SDR) you’ll learn how you can write software to hack remote control security gates, track ships at sea, code your own aircraft radar, and ultimately how to download data directly from various satellites in low earth orbit with nothing more than a cheap USB dongle and a makeshift antenna.

    How can CB radio or Ham radio communication be achieved with SDR and a laptop?

    You’ll find that South African authorities are quite draconian in their view as to who can listen to what compared to the Americans for example. In South Africa they get quite peeved if you receive police and listen to their dispatch radio transmissions.

    I have SDR dongles since 2013

    aliens watching humans on Earth…doing this already…hacking satellites for free internet access…albeit it is much slower…perhaps they have methods of boosting reception.

    Hacking satellites? …pfffft.
    This video is NOT Captain Midnight approved.

    Not all squawk codes starting with 7 are bad.
    There are three which indicate an issue.
    7500 – Unlawful interference with the safe conduct of the flight (hijack)
    7600 – Radio problems.
    7700 – General emergency.

    In the UK (and some other places), 7000 is the general VFR conspicuity squawk. If, for example, I am talking to Scottish Information and they have given me 7401 (which is usual for Scottish information) and I want to change to the frequency of my destination airport, I will be told to “squawk conspicuity and freecall xxxx” (where xxxx is the destination airport). At that point, I will change my squawk code to 7000 (as I am flying VFR) and change the radio to the frequency of my destination airport.
    Squawk codes are changed en-route and not always assigned prior to takeoff. I will generally depart my home airport on 7000, change to Scottish Information where I will usually be given 7401. If, during my journey, I want to transit Edinburgh’s controlled airspace, I will change to Edinburgh Radar’s frequency and will be given a different squawk code (usually 043… something – they have a bank of squawk codes that they issue, starting at 0430). After completing my transit I will return to Scottish Information and will be told to squawk 7401 again.
    This guy’s knowledge of transponders is somewhat faulty, but that can be forgiven as he’s not involved in the world of aviation.

    Mrs Richards: "I paid for a room with a view !"
    Basil: (pointing to the lovely view) "That is Torquay, Madam."
    Mrs Richards: "It's not good enough!"
    Basil: "May I ask what you were expecting to see out of a Torquay hotel bedroom window? Sydney Opera House, perhaps? the Hanging Gardens of Babylon? Herds of wildebeest sweeping majestically past?…"
    Mrs Richards: "Don't be silly! I expect to be able to see the sea!"
    Basil: "You can see the sea, it's over there between the land and the sky."
    Mrs Richards: "I'm not satisfied. But I shall stay. But I expect a reduction."
    Basil: "Why?! Because Krakatoa's not erupting at the moment?

    Can you track police vehicles

    I'm sure they have some kind transmitter that identify the police car, motorcycle or police officer or police radio location. TIA

    I have a SDR Play RSP DX, Works much better than the Cheap Chinese Made SDR Dongles! I'm also a Licensed Ham Radio Operaters to, I have a Yeasu FT817 it's a whole Ham Radio Shack because it have HF, VHF, and UHF, All modes, I use SDR Angel Software and SDR Uno for My SDR Play RSP DX!
