unit731 Posted February 18, 2009 Report Share Posted February 18, 2009 Laws and mandated technology may vary from country to country. Here, I was talking to someone about cell phones. He had a nice pretty IPhone V2. He bounces from Blackbery to IPhone - depending on the mood of his boss. Anyway, he claims/states that all cell phones can be tracked even if the cell phone is turned off. In other words, if the authorities know your cell phone number and even if it is turned off - they can find you (well - the cell phone that is). On or off - they can locate you (the cell phone). On or off. Tracking. Anyone out there have knowledge of such snooping technologies and cell phones? Link to comment Share on other sites More sharing options...

kamui Posted February 19, 2009 Report Share Posted February 19, 2009 The cell phone has to be "on". Maybe he mixed it up with another possible manipulation of cell phones. A cell phone can be turned into a listening device from outside without the knowledge of the owner of the phone. Therefore it is no surprise that you read regularly that in super secret meetings all people have to hand out their mobile phones and that the batteries are being taken out.

Mentors Posted February 20, 2009 Report Share Posted February 20, 2009 The cell phone (or 'handy' if CTroy wish i say ) has to be "on". In Switzerland we have a service for alpinists/mountaineer. If one get in troubles a special rescue team can find him. Link to comment Share on other sites More sharing options...
kamui Posted February 20, 2009 Report Share Posted February 20, 2009 On or off. ARTICLE Thanks for article. It has a good explanation: Kaplan's opinion said that the eavesdropping technique "functioned whether the phone was powered on or off." [color:red]Some handsets can't be fully powered down without removing the battery;[/color] for instance, some Nokia models will wake up when turned off if an alarm is set. The U.S. Commerce Department's security office warns that "a cellular telephone can be turned into a microphone and transmitter for the purpose of listening to conversations in the vicinity of the phone." An article in the Financial Times last year said [color:red]mobile providers can "remotely install a piece of software on to any handset, without the owner's knowledge[/color], which will activate the microphone even when its owner is not making a call." Nextel and Samsung handsets and the Motorola Razr are especially vulnerable to software downloads that activate their microphones, said James Atkinson, a counter-surveillance consultant who has worked closely with government agencies. "They can be remotely accessed and made to transmit room audio all the time," he said. "You can do that without having physical access to the phone." Because modern handsets are miniature computers, downloaded software could modify the usual interface that always displays when a call is in progress. The spyware could then place a call to the FBI and activate the microphone--all without the owner knowing it happened. (The FBI declined to comment on Friday.) "If a phone has in fact been modified to act as a bug, the only way to counteract that is to either have a bugsweeper follow you around 24-7, which is not practical, or to peel the battery off the phone," Atkinson said. Security-conscious corporate executives routinely remove the batteries from their cell phones, he added. Link to comment Share on other sites More sharing options...
