After an accidental chemical release or a terrorist attack I’ve found out exactly what was going on thanks to my scanner. I can’t tell you the number of times I’ve found out exactly why a helicopter had been circulating the area or what the huge firetruck response was all about. Perhaps the oddball hostage situation.įor the overwhelming majority of police radio communication, they need to be transmitted live and in the clear. There are some communications that need a delay, but only a short delay. An example might be the name of a rape victim or an abused minor. There are some communications so private that they should never be made public.

A jammer can be set to only jam encrypted communications.

But for us the most interesting part was starting at about 15:30 when the presenter,, talked about directed jamming that can be used to alter law enforcement behavior. That means you can track who is talking to whom. The IM-ME can be used to decode the metadata that starts each radio communication.

There’s a lot of interesting stuff in there. Join us after the break where we’ve embedded the thirty-minute talk. Or rather, ability to do amazing stuff with the hardware is what makes us perk up.ĭetails about this were presented in a paper at the USENIX conference a few weeks ago. We’ve seen this ‘toy’ so many times… yet it keeps on surprising us. Would you believe you can track, and even jam law enforcement radio communications using a pretty pink pager? It turns out the digital radios using the APCO-25 protocol can be jammed using the IM-ME hardware.
