How To Tell If Your Cell Phone Is Bugged 338

Posted by kdawson
from the your-shoe-is-ringing dept.
Lauren Weinstein writes to point us to his essay on the realities of using an idle cell phone as a bug, as a recent story indicated the FBI may have done in a Mafia case. From the essay: "There is no magic in cell phones. From a transmitting standpoint, they are either on or off... It is also true that some phones can be remotely programmed by the carrier to mask or otherwise change their display and other behaviors in ways that could be used to fool the unwary user. However, this level of remote programmability is another feature that is not universal... But remember — no magic! When cell phones are transmitting — even as bugs — certain things are going to happen every time that the alert phone user can often notice."

      There is another approach - take off the cover which protects the battery. Underneath the battery, you will see how two wires are connected. If the color of the wires is green, then you're bugged. Otherwise, if the wires are red - it's a bomb.

      Other colors are not defined by the standards, so if your phone has wires which are not green, nor red - you have a counterfeit phone.

    When cell phones are transmitting -- even as bugs -- certain things are going to happen every time that the alert phone user can often notice.

    For example, when using a Palm Treo 650, the phone will crash and reset often, and without notice.
    • I can attribute every single crash/reset of my phone within the past six months to a year to particular apps on my phone. In this case, it's GNU Keyring. Keyring really likes to crash my phone if I haven't used Keyring in a while. It's Keyring's way of telling me it wants more love. :)

      It can just be using the mic and battery for its service, but generally the chirps would give it fully away.

        In effect, the phone radiates more than necessary and the battery gets drained faster.

        The idea is to detect if the phone is listening while a call is not being made. We already know that FBI listens to criminals during the actual phone calls (through the service provider, the old way). And cell phone radiation is a problem only when the phone is next to one's brain. Since the flasher has no function while a call is being made (it flashes anyway) so it can be taken off if radiation is being considered

        I don't know what typical cell-phone batteries are rated for, but for example for two typical NiMH AA cells (2800 mAh each), the LEDs are probably using no more than about 3-6% of the total battery capacity per hour (depending on how many and what kind and how bright the LEDs are; 3% would be about 10 typical red LEDs, 15 mA @ 1.7V).

        What, did you sleep through elementary physics and the principles of EM radiation?

        A cell phone is nothing more than a fancy radio with an omnidirectional antenna. That antenna, per its name, is going to radiate a certian amount of RF energy in all directions. RF that is radiated in the direction of the cell tower will be recieved by the antennas on the tower. RF that is radiated in any other direction will gradually be absorbed by the surrounding environment to no practical effect. So if your LED RF detector happens to be in the close vicinity of your cell phone when the phone is transmitting, it's going to be hit with RF that wouldn't have hit the cell tower anyway!

        The only possibly conceivable way that the LED RF detector could have any impact on the signal strength between the cell phone and the cell tower is if it was exactly in the path between the cell phone antenna and the cell tower antenna. The probability that this would occur is so small as to be trivial, and with the wide angle of radiation on most cell phone tower antennas, and the fact that there is usually more than one antenna for any direction, reduces the probability effectively to zero.

          No, radio does not behave like that.

          The GSM radio wavelength is about 30cm which means that in effect all objects which affect the radio path, including the transmitter and LED receiver, are "blurry" in space to the scale of 30cm (this is an order of magnitude, not an exact value). The phone itself, and the distance from the LEDs, are much smaller than that. So the directionality of the radiation is nearly irrelevant to calculating how much is absorbed and transmitted.

          In other words, contrary to the parent post, the LEDs attached to the phone will be effectively on the radio path to the base station, no matter where they are attached on the phone.

          It's counterintuitive that you can have a radio signal between two small antennae at A and B, and something that's nearly in between but off by say 10cm affecting the signal between A and B, is though attracting the energy towards it (even bending the beam is possible). But that is exactly what happens. Waves are like that.

          It's more complicated than that, however, because the LEDs are also in the "near field" - the region where there may be a non-radiating component to the oscillating EM field around the phone transmitter. In this region, the LEDs could, if they are constructed to do so, absorb energy from the near field, and, depending very much on the phone design, potentially do it without affecting the radiated signal.

          Also, it is possible that they absorb some of the radiated energy but if they use very little power, not affect it very much.

          So we can't easily say what effect the LEDs will have on the transmitted signal, but the parent's argument about having to be "exactly on the path" to the transmitter, as in a straight line, is not correct.

        Yeah, but some aren't. I had an interesting run in with some credit card scammers earlier this year. I got a call from my credit card company about 10 minutes after I bought lunch one day. It was from the fraud early warning system, which I'd gotten a few times now. These were usually due to me flying around the country, or taking extended road trips, or making very large purchases ($900 in appliances, $1500 in furniture, etc.). I wasn't too worried about it.

        This time, though, I it asked if I could verify a purchase for "theme park tickets," "appliances," and some other things. I told it no, and an amazingly easy 15 minutes later, my account was frozen, all the obvious charges were rolled back, and a new card was on the way, along with some paperwork for me to flag other charges that the CC company missed.

        The scammers had my old address apparently. I knew this because they tried to order a convection oven (who'd have figured?) and have it shipped to my old address. My guess is that this is the address in whatever database that got cracked. When I did get my next statement, I noticed a few charges to some random "music store" .com that was based in the same state as this old address, and donations to a charity of a few cents.

        It turns out that credit card company had cancelled far more of these "song" purchases, and "donations." The thieves had made, over a few weeks, donations of varying amounts from a few cents to about $2, and random song purchases of about $1. It seems that they were trying to establish that I was "normally" spending money in the area where I used to live, and also verifying that my card was still legit.

        So yeah, some criminals are dumb. Others are not. The fraud detection systems we have are pretty good though.

    Ultimately, the question in this scenario goes far beyond the immediate problem posed here (cell phones being used as bugs), but lends itself to the more interesting question about why privacy should be held as one of the most important things in our society. I am of the persuasion that the following quote from The United States constitution should stand as one of the most important parts of our society -- and if you're not from the United States, than imagine that I'm suggesting you include this in your Government's constitution/body of laws if it is not already there...

    The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.
    This has always stood as one of those easily reinterpreted components of the constitution -- just look at the way the US Supreme Court enjoys reinterpreting [erowid.org] it. And, to some degree, I do see why this should be interpreted in a somewhat fluid way. There are terrorists/freedom fighters out there, and governments should be capable of protecting their citizens-- that is what they're ultimately designed to do.

    However, the egregious trampling of our right to privacy, as outlined in the US constitution, starts moving us very quickly in the direction of fascism [wikipedia.org]. And people tend to use the term fascism lightly, but you have to ask yourself how a state can move from one type of government to another? History has shown that this happens everywhere -- just [wikipedia.org] look [wikipedia.org] at [wikipedia.org] history [wikipedia.org]

    So, why would I take a break from my ultimate presentation on latency markers in tuberculosis? Well, I feel strongly that you (the person reading this, not just the general "you") should take it upon yourself to encourage those people that you vote for to stand up and strengthen the first levee against tyranny -- our right to privacy. The FBI may, at this point, consider using your cell phone to track you as a legitimate means to and end, but when the FBI cycles through it's current leadership/membership then we can only hope that these means lead to good ends.

    And the hope that people mean well is not something I am willing to risk.

    It would seem to be much easier to have the phone record to its internal memory and then transmit later. Transmitting needs a fair bit of power (while recording to memory from the microphone doesn't take much and can be compressed) and I would think people would start to notice that their phone would be dead after powering it off for several hours.

      First, a bugged phone could still record what you were saying and transmmit that later. Remember that the people who bug phones don't want them to drain their batteries dry in only a couple of hours, it would be suspicious.

      Secondly, those bars are more a qualitative information than a quantitative one, at 4 or 5 bars, the signal is clear with low power, with less bars, it means that there are transmition errors or that the radio needs a boost, either way, it is an indication to the phone it might be a good idea to look for another base station, but only a "no signal" notification will prove (if you can trust your phone display) that it is incapable of communication. If you shield your phone, it won't see any good base station and will lose a lot of energy scanning the frequencies looking for one.

      You can try to shield your phone, but then, you need to test its effciency. I once tried to put a phone in a tin box and I still could call it. Of course, grounding that box terminated the call.

      So I would say shielding is a lot of effort for what you want, if you are only slightly paraniod, shut the bugger down, if you are a real paranoid, leave it at your place with the TV on (during a movie you already saw, in case they will check your alibi) then use the bus to meet whoever you need in a parking lot.

  • OK, this has come up a lot in many conversations.

    First off, cell phones have batteries internally, much like the battery your mobo has to keep it's settings.
    Why would cell phones differ? Take your main battery out, the time/alarm/etc settings are saved, doesn't that give you any clues?

    The phone is powered at any given time, it's not a matter of whether the screen is lit or not...

    They could, and can, and do, use cell phones as bugs, there's nothing new to that.

      Having enough juice to keep the clock ticking over is one thing, having enough to power a transmitter or recording circuit is a whole different level. I love my cell phone, it lives with me 24/7, do I worry that it is watching me? Nope. I'm an ex 'them' (I don't change my IMSI and IMEI regularly just for fun though)

      Umm, cell phones get their time and date from the TOWERS not from an internal clock, this is how it adjusts when you move to another time zone. Magic huh? Settings are saved in the SIM or other non volatile memory location.
  • There's nothing in this "article" that the discussion related to the original bugging story did not already cover in much greater detail. No news is better than crappy news, slashdot.

    If we are concerned with the ability of somebody to alter the phone's behavior sufficiently to initiate a call without your intervention, then we shouldn't assume too much about what other things can or cannot be done.

    For example, not being able to make a call when a call is in progress. In time division multiplexing, you're taking one or two timeslots out of eight or sixteen. However, it's pretty clear that if we have modified the phone ostensible behavior enough to use it as a bug, it could also take more than one half channel at a time.

    Checking the warmth of the phone is good idea, but not perfect either. The assumption is that the phone is transmitting your words live. What if the phone recorded your conversations at a reduced bit rate, say 3kb/sec, using voice activiation. It could the be stored and dribbled out intermittently, particularly when close to a cell tower. This would reduce telltale power effects. This might not be enough to monitor your every waking moment, but it could be used to monitor snatches of your conversation, particularly as part of a surveillance program.

    Even if the phone doesn't transmit your speech, it could use the signally channel to record that you are talking, combined with the GPS or wi-fi snooping, over time the network of people you talk to could be recontructed.

    It's a bit paranoid to worry about these things, unless you think the government has a compelling reason to snoop on you. But if you do have such a reason, then you shouldn't make too many assumptions about what they could do with a phone, particularly a "smart" phone which might have megabytes of storage. A simpler phone with a removable battery would be a good choice.
    • Unfortunately a simpler phone wont have the desired effect either. CCITT 7 is a pretty complex little beast, used not only by GSM these days, but is also replacing older dialing methods for regular land line phones as well. SS7 is common, much the same way air is common, over time it does provide a detailed map of an individuals network of contacts - many layers deep.

    If your phone is warm to the touch even when not in use, is that an indication of bugging or a battery designed by Sony?
  • A 2003 lawsuit revealed that the FBI was able to surreptitiously turn on the built-in microphones in automotive systems like General Motors' OnStar to snoop on passengers' conversations. When FBI agents remotely activated the system and were listening in, passengers in the vehicle could not tell that their conversations were being monitored.

    I missed this when it happened, but I always suspected as much. Imagine this...

    Driver: Hand me another brewski.
    Passenger: Here you go.

      Actually there was a problem with OnStar employees doing this to some famous people and or their ex for kicks.
      I am pretty sure that you can find kits on line that add an LED that lights up when you the mic is active or a switch that kills them mike

    Just phone your own land-line and then say, "Binladenbinladenbinladen" 10 times.

    Wait 30 minutes.

    If there are no black helicopters after 30 minutes then you probably aren't being bugged.

    If you're really worried, get a hex die from a gaming store. Then get
    8-16 *different* friends to each buy you a prepaid phone. Number them.
    When you need to make a call, roll the die, use the phone, toss it in
    the trash or better, give it to a random teenager to use up the minutes.

We don't know one millionth of one percent about anything.
