If like many people, you have a home security system, it's probably not as secure as you think; a $10 SDR can be used to pick off the unencrypted wiress signals emanating from the sensors as well as trick the receiver into thinking it's receiving normal signals from those sensors.
Lamb was able to suppress the alarm through intercepting the system’s unencrypted wireless communications with the sensors around the home, and sending his own signals to the main controls.
Using his methods, a would-be tech-savvy thief could suppress an alarm while going in and out with your stuff; a prankster neighbor could set your alarm off; or someone could monitor when you’re active at the house. At the very least, someone with an SDR could determine based on signals being sent whether you actually have an alarm system, or have just planted a “Protected by ADT” sign in your front yard.
That latter use is where your ten-dollar SDR, purchased from Amazon, comes in. With a more expensive and sophisticated unit, full control of an alarm system can be achieved from as far as two and a half football fields away, which is why thieves could simply override the system as they cart your stuff out of your crib.
Of course, the feds have been doing this for years.
Sleep well tonight.
