Can Amateur Radio Pick Up Cell Phone Calls?
Make it a point to switch on your police radio after you get home from work or school and see what's going on in your area. In many places, crimes tend to be committed in higher numbers in the early evening and late at night. This means the hours between about 3pm and 2am EST are typically the juiciest times to listen. Keep an ear out during special events to intercept interesting calls. If there's a big concert or football game going on in your city, be sure to leave your police radio running.
Police officers are dispatched in greater numbers during these events, and need to be able to communicate with one another easily from different locations. With so many people gathered in one place, you're sure to overhear something out of the ordinary.
How to listen to cell phone calls?
Be prepared to intercept a lot of noise complaints, car accidents, and drunk-and-disorderlys. Listen for increased excitement surrounding urgent calls. It can be easy to tune out the routine talk when there's not much going on, but pay close attention when the exchanges between the dispatcher and responding officers get louder and faster. There will often be a noticeable shift in tone when a major incident, like a mugging or vehicle pursuit, is going down.
These days, numerical codes aren't used as much, so it's not necessary to try to memorize them. Listening for subtle changes is a more reliable way to catch the big calls. Stay up-to-date on important occurrences nationwide as they unfold. With a police scanner app, you're not limited to the reports being issued in your own community. Spend some time on channels for other cities, states, or corners of the country to catch wind of the latest breaking developments in those areas before they hit the news. Don't forget that police scanners can pick up fire and EMS channels, as well. This makes it possible to keep tabs on a certain event even after the police have left the scene.

Remotely Eavesdropping on Cell Phone Microphones
You have to take care of yourself in this world. Considering the federal government in the U. After delivering and installing some Trojan via an unauthorised service SMS they claimed to be able to have a remote access to the handset including listening to conversations, copying contacts etc.
And no I have no connection to the company other than one of it's founders used to be the MD of a company I worked for. From a software perspective this is extremely easy. However inbuilt OS security in all of the mobile OSs I know mean the chances of such malicious code being installed by a 3rd party is extremely small. That said it is very easy for the network opperator to silently install whatever they want over the network. Given how they rolled over for the previous federal wiretapping scandle nothing would surprised me Sprint started supporting FOTA right after my departure so I can only guess at what the process looks like from the user's end, but I imagine that even a normal update with modal progress dialog would be dismissed as "just another update or something.
Mobile phones are major security and privacy holes, and things will get much worse before they get better. I discussed this with a colleague who was once in cellular customer service. Remember car phones? I'm talking about cellular phones permanently installed in vehicles. Some of them were manufactured and installed with an "auto-answer" feature that was meant to be safer and more convenient for a driver. But at least one model had a disconcerting problem: it would answer a call without ringing. In at least one case, a subscriber called customer service complaining that he was caught in some unauthorized extra-marital activity, because "that blankety-blank phone answered on it's own.
So, what we need is a clamshell holster for mobile phones with electromagnetic shielding all around, good quality acoustic insulation to attenuate voice leakage, and an internal device situated right at the phone's microphone pickup that feeds it a random electronic yodel? Did I miss anything?

Wait for your target to walk by you while he talks on his cellphone. Listen :. Roy I would rather prefere to see the spread of an open source cellphone platform s , like qtopia, tuxphone, openmoko etc. Exactly, but a very familiar problem everyone's favorite OS is more likely to repeat than not with a proprietary network.
Are consumers demanding an open phone, or a service that makes it easy to separate client from the target see my comment above -- imagine phones designed to not be tied directly to an owner. Ironically, the limitations of the mobile platform could help reduce the complexities and thus enable exposure of vulnerabilities, but instead they might also be a perfect excuse for shortcuts and control gaps driven by "market" forces.
I read the actual evidence referenced by the original story and didn't see any evidence to support the article's claims. In fact, it seems clear to me that some other kind of equipment must have been used in this case, because the opinion talks about it working even when the cellphone was turned off.
I don't believe any cellphone out there can run a program while turned off or do anything else, much less transmit, without hardare hacking. Therefore, contrary to the article, it must've involved a physical hack of the cellphone such the transmitting battery suggested earlier in the thread. The original article also implies that a "roving bug" mentioned in the legal documents is the technique for turning cellphones remotely into bugs.

That's rather likelier to be legal language referring to the "roving tap" authority needed to establish mobile or otherwise especially intrusive taps under a mechanism established by the Patriot Act. The legal language around the term seems to support that. So unless all sources of power e.
In fact, mobiles are often designed to allow "always available" functionality with default-enable across multiple networks even though you might press the "off" button and save some power. I assume they atleast do code signing or something similar to protect from unauthorized access, but imagine the payoff from pulling this off: You can basically blackmail entire societies with the threat to render their cellphones inoperable.
Unfortunately, "Off" is very rarely off these days. As was mentioned earlier, most phones will happily turn themselves on if there is enough battery left to trigger alarms etc. Periodically, I'd get the phone to add a. My phone has a 1GB flash card - that's a lot of voice recording time Why bother, when it seems most people do not change the default PIN on their voicemail?

At mw of power, it would not get warm or anything. A lot of current phones have speakerphones on the outside. They are worse at filtering out background noise, on purpose, and are on the outside for clamshells so would make excellent bugs. I assume any device that has access to power is more or less on. If I was in a criminal enterprise I would pull the battery at certain times. You know, it's amazing how perfect we assume the government and large organizations are when we're being paranoid. Mafiosos are people, too.
Police move to block the public from listening to scanners
Plus, the top Mafiosos are generally arrogant, and arrogant people make mistakes by the ton. Add GPS and stir, briskly. The phone also detects when it is plugged into a charger. Funny that the latest Motorolas don't let you use unauthorized chargers, isn't it? A convenient time to do the upload -- or just time-share the data stream during a voice call.
The classy approach is to have shielded small lockers with white noise in the vestibule of your operations area.
