Las Vegas – A security researcher has created a mobile phone base station equipment to route through his own outbound call, allowing the interception was in the clear, or even encrypted phone handsets

in low-cost, home brewed equipment, especially developed by the researcher Chris Paige,blackberry charger, imitation has been used by intelligence and law enforcement agencies, more expensive equipment – the so-called IMSI catcher – you can capture the telephone ID data and content. These devices are basically cheating the legitimate GSM mobile phone tower, to attract them to send a signal by transmitting tower in the area than the legal stronger data.

Paget’s system costs only about $ 1,500,unlocked china phones, compared to hundreds of thousands of professional products. Most of the price of the laptop he used to operate the system.

Paget’s equipment to capture only the GSM 2G phone,iphone cable, so AT & T Inc. and T – Mobile phones, which uses GSM, easily intercepted. Paget’s aim is to highlight the GSM standard, allowing the capture of a rogue station called loopholes. GSM is the second-generation technology,blue tooth, as 3G technology security.

Encryption call blocking are not protected, because this rogue towers can simply be closed. Although the GSM specification that a phone should pop up a warning, and when it does not have to connect to a single encryption, SIM card, disable this setting to not display alerts.

the device may be corporate spies, criminals, or private investigators to intercept private phone targets.

Paget received FCC officials who on Friday presented his list of demonstration may be contrary to the provisions of the call. In order to solve legal problems,body stocking, he broadcast a ham radio, 900MHz, this is the same frequency and the European GSM mobile phone spectrum used by GSM towers in order to avoid possible violations of U.S. law.

just turn the antenna on a cell phone caused a two-room tower is connected to Paget. He then set it to deceive the AT & T towers to capture customers from the telephone operator.

\\During the demonstration

, only about 30 cell phone is actually connected to his tower. Paget said that the phone can take time to find the signal and the shift of the tower, but there are ways to speed up the process.

to solve the privacy problem, he set up a recording system to provide information to anyone who tried to time from the tower room with his phone. Sources, their calls were being recorded. Paget records all the data is saved to a USB memory stick, which he destroyed after the speech.

customers to use GSM operators can try this from their mobile phone by switching to 3G mode, if it is a choice way to intercept their calls.

but Paget says he can capture the noise interference,best video camera, stop using 3G mobile phone 3G. Phone will then switch to the 2G and the hook with his rogue tower. Paget has his interference, and a two-stage amplifier, but refused to put them in that they would \

Overall,cell phone provider, this does not mean much. Yes ah, you can hear all you want to talk, but without any background, it is quite worthless. In addition, the government has a technology – big deal.

Hackers FTW

\Analog phone era,wedding dresses online, you can only transfer a old (60′s – 70) 69 TV channels and listen to phone calls any of the above: The Federal Communications Commission extended to UHF television channels 70-83 mobile phone coverage. and the phone early age (late 80s, early 90s), most radio sale, can receive 800MHz, (Radio Shack’s, Uniden, etc.) locked in to the phone call, but a simple way to cut diode (allowing the scanner usually) break the lock.

I guess you can set at least some of the only 3G phone is 3G,green laser pointer astronomy, which will protect you the skills, but will mean you are less likely to make / receive calls (or because you are not in a 3G area or because the 3G system is busy, it routes you to a 2G system)

@ thousandsun – if he has a ham radio license and ham frequencies _also_ is the use of 2G (900MHz like the article said), he was may be in the clear, especially when he went his way to show a lack of evil intent (in the demo …)

So how long before someone hacked AT & T, Microcell, and only sets where they want to block incoming calls? It would, after all its Internet connections, hackers set up the equipment and the environment in your language of choice, I am sure there will be stronger than the micro-area network signal strength around

only interesting in this article is that most people do not know how happy the technology, they rely on. No one really cares about, and how, until they become targeted.
