After the news that China has decided to force manufacturers to standardise phone charging ports to the mini-USB format, it turns out that there’s an even easier way to get the industry-wide feature you want implemented: just be the FBI. What cellphone manufacturers are reluctant to include in-among all the blurb about Bluetooth and high-speed data connectivity is that apparently every recent phone sold in the US has a built-in tracking device that, once activated remotely, can be set to keep the microphone powered on even when the phone itself is switched off.
The FBI used the technology in collecting evidence for the recent Genovese crime family trial, and it should be made clear that they can only do so with the relevant court order. Saying that, just how difficult is it to get a court order in our age of super-terror? The only way to circumnavigate the tracker is removing the battery, which then makes the phone rather useless. In fact, you’d be better off carrying a small child’s shoe, which could at least be used for storing your keys.
I’d be very interested to find out whereabouts in the phone circuitry the tracking device is located, from a purely geeky point of view. Anybody fancy hacking open their KRZR and going looking?

Ok, so it’s probably not much more than an urban legend yet, but this unauthorized listening could be defeated by putting the phone in a sound-proof carrying case with an electrically conductive lining. This kills both the detection of audio and the ability to broadcast the detected audio to the cell network. It should be easy to build and test such a box. Expect to see such cases offered for sale.
Or just leave the phone in the car while you talk in the house.
But make sure all your friends do, too.

If you are just afraid of s.o. listening to your conversations you might better just interrupt the microphone line with a switch. This way you can still receive phone calls. But beware: as there is a constant exchange of information between the phone an the base station you could still be tracked in this case …

I’m sure the functionality would be part of the firmware.
To anyone who says they never do anything illegal, it is impossible for anyone to say that since no living human knows all the laws he is subject to. The fact is, EVERYONE does something illegal now & then. Mainly you’ve only gotten away with it as a matter of severity and whether the hardware is yet in place to catch you in the act. But the latter is changing. With sufficient surveillance, everyone will be arrestable. Soon, even your car’s computer will tattle on you.
Ever discard your old telephone book in the trash instead of recycling it? Ever send a box of brandy chocolates to a relative in the states of Florida, Maryland or Michigan? If so, that’s actually a felony. Ever cut the tag off your mattress? Fail to submit state sales tax on an internet purchase? Oh, you are a real sinner. Ever drive without your seatbelt fastened? Exceeded 55 miles per hour? Failed to come to a complete stop at an intersection? Forgot to signal your lane change? If so, you are a scofflaw and deserve to be jailed for the good of society!

I wonder if it would be possible to activate this without being the FBI? Could be an interesting hack if someone figured out how to call a cell phone and activate the feature. Do that to enough phones, and you could cripple the wireless grid with cell phone usage. Would cause trouble for emergency service.
What a mess. And sadly the FBI couldn’t be held liable for such damages, since it’s pretty close to impossible to hold a Federal agency liable for doing (or not doing) anything… just ask Hurricane vics, 9/11 families, etc. etc.
This could be such a gigantic mess if it were hacked. And it’s not something that could easily be fixed either. At a minimum a firmware upgrade would be needed, so all but a handful of phones need to physically be taken to the store, since FOTA is only supported on a few phones.
Can you imagine congress passing an emergency law requiring cell phone users to get a firmware update within 30 days?

-1cybergeek December 30, 2006
Hey guys,
This is so easy for us, the techies. Just put on a costumed flip-close switch in series with the mic. That’s all…. Because if the phone is not flip open, the circuit of mic and main amplifier will be open, hence no voice signal can go through to reach the amplifier. And that once the cell is flipped open, the mic completes with the circuit. Simple as pi. :-)
NeutralMr E. December 31, 2006
The real issue here is if such a thing did exist, it would be used by parties other than the FBI far more frequently. Imagine how much personal info the identity thieves could get from you by using this? And to say “Oh its not crackable because we never told anyone how to do it” is BS.
Someone will figure out how to take advantage of it. If its real (I doubt it) then its only a matter of time.

I waer my phone on my hip, in a leather case, i know for a fact that you cant hear anything if you are listening while the phone is in the hip case. I know this, becuase until i learned to lock my keypad, it would often call people and they woudl get to hear ambient noise for a while.
I am skeptical of such a ability being added to recent phones. I suspect that this is actually a rehashing of a bluetooth exploit that was actually closed by the phone comminuty in recent years. The said exploit only worked via bluetooth and was limited by the physical range limitation of bluetooth.
However I wonder if there is anything to actually add to a phone to make this technically feasible. The phone carrier is already connected to your phone in a passive way. It is possible to conceive that they could send a signal that opened a call. hmmm.

+1Court Kizer December 31, 2006
I don’t actually believe this. The FBI, probably did what they have done since the 1920’s, which is modify the phone so when it’s “on the hook” or in this case not on a call it’s transmitting to somewhere close by. Meaning they probably got the phone modified, and had a longer range transmitter installed. There are plenty of sites on the internet that will show you how to do this for yourself.
+1Court Kizer December 31, 2006
Not to mention it’s mostly the phone calls they listen to, which they just get a warrant (or not) to listen in, and it’s easy as cake to listen into the call, but for ops where they want to listen when the phone is off the hook it draws battery power. My guess is somehow they switched out this guys battery with one that had the transmitter installed, or somehow modified his phone.
If this was built into every phone, I think we’d probably know about it (there are always leaks). There are many models of phones (even 5 years ago) that could do this simply by going into diagnostic mode, and changing options where it would be transmitting to the cell tower when you ended your call.

+1TerraHertz January 2, 2007
Very simple test to see if this is being done to your phone. Buy one of those little LED gadgets that lights up when its near a phone that is transmitting. Even if the phone is ‘pretending’ to be off, to transmit the voice signal it still needs to transmit RF. Normally phones transmit short RF bursts regularly even when not on a call, so they can maintain their link to the nearest cell base. But while the phone is sending voice, it transmits much more often. You can hear this if the phone is near a poorly shielded stereo or other audio device – the ‘brrrt brrt brip brrt…’ sounds are the RF packets the phone is sending, being picked up by the stereo amp circuits.
NeutralIf your phone starts doing this while its supposed to be switched off, you have a problem. Exactly the same problem we all have (an insane, out of control US administration) but focussed right on you.

It’s too noticeable. Standby time on cell phones is now, what, over a week? Talk time is what, a couple hours? If your cell batteries are always dead, you know something is up. Sure, they could get around it by only switching it on when you’re doing something interesting (read: Incriminating) but otherwise, they can only get a few minutes a day without a paranoid you noticing. And, if you’re sufficiently paranoid and intelligent, you could force them to tip their hand. Start talking about the dead bodies you keep in your basement, and when they raid your place, you know they’ve been spying on you.
Or, instead of the switch between the battery and the phone, install a milliamp (microamp?) meter, which senses how much power the phone is drawing. If it trips for more than a couple seconds at a time, you know that your phone is drawing power, and it only draws significant power when it is transmitting.
