[liberationtech] If we want to be anonymous in #azerbaijan we take batteries out of our cellphones

Hi Liberationtech folks, is this always the case? I've heard cases where
people can still be tracked whether they have batteries in their cell
phones or not...

I've spoken with mobile security researchers who have given me the

theoretically possible that some phones could be recording or
transmitting without the main battery, but the equipment that would be
required to test is prohibitively expensive and you'd have a hard time
demonstrating anything but an evidence of absence.

Unless there's a specific secondary battery powering a transmitter, it
is improbable in the extreme that an unpowered passive device can have
its location tracked at a distance of more than, say, a hundred meters,
and any tracking at all is extremely unlikely.  Cellphones don't work
that way, and physics says no, basically.

Now, *people* are very easy to tail, when you have a human doing the
work.  That's a different story.  There are almost certainly many more
pressing issues to worry about when it comes to locational privacy than
a battery-less phone.

Yeah, I wouldn't want my answer to be interpreted as providing
evidence for it. I'm not advocating breaking any laws in this forum,
but especially not laws of physics.

 As Eleanor said, if there is no power source attached to
 telephone, or to whatever secondary tracking device installed in
 the telephone, then it is not possible to track someone. No power
 source, no radio frequencies being created, no transmissions of
 information.

Right. On a specific device, you could imagine a secondary battery
powering the tracking device (er, the radio) but it's hard to imagine
a scenario where that's the easiest way to track somebody.

The conversation I had with the security researcher was actually about
a related question, and that's whether airplane mode could be
trusted as well. Again, I don't want my acknowledging a theoretical
possibility to be taken as advocating a hoax or anything, but the
agreement was that SOFTWARE solutions like airplane mode can't really
be trusted, and some processor components do not have open-source
software options. Of course, on a current iPhone, there isn't an
option to remove the battery.

Hope that clears things up a bit!

Thanks,
Parker

Some laws were made to :)

 Right. On a specific device, you could imagine a secondary battery
 powering the tracking device (er, the radio) but it's hard to imagine
 a scenario where that's the easiest way to track somebody.

Absolutely, and again like Eleanor said it would (probably) be a) cheaper b) 
faster, and c) more efficient to have someone follow in person. People forget 
social engineering is a very powerful tool. It doesn't need sophisticated 
technology and lots of money.

 The conversation I had with the security researcher was actually about
 a related question, and that's whether airplane mode could be
 trusted as well. Again, I don't want my acknowledging a theoretical
 possibility to be taken as advocating a hoax or anything, but the
 agreement was that SOFTWARE solutions like airplane mode can't really
 be trusted, and some processor components do not have open-source
 software options. Of course, on a current iPhone, there isn't an
 option to remove the battery.

That's a whole different scenario. In this case you are relying on the device 
maker to control shutting off the power to the radio modules (GPS, GSM, WiFi) 
to put the device into airplane mode (whatever the hell that actually means). 
Knowing how shoddy some device makers can be, I'd prefer not to leave my 
security and life in their hands.

Certainly in this case, the device is still powered on, and if there was any 
rogue software installed which had the intelligence to engage the microphone to 
record the ambient audio, or to store information on the device to send it once 
it was reconnected to a data network, this would be trivial to do.

The safest advice is still to remove the battery from the device. If needs be, 
keep it in a sealed container so there is no possibility of recording ambient 
audio. (Although I do not know how useful this would even be)

Bernard

I'd like to remind everyone about the Great Seal bug:
https://en.wikipedia.org/wiki/Thing_(listening_device)

Sometimes the source of power isn't in the device itself.

It might be cheaper to tail someone but in some cases, TEMPEST emission
attacks, laser microphones and epic bugs, like the Great Seal bug, may
be more effective...

YSMV! :)
