Chris Dougherty, Activist Post - Most people believe their phone conversations are private. Well, they may not be as private as you think if your office or home is filled with hacked phones.
Researchers at Columbia University have discovered a flaw in telephones that allows a hacker to turn a phone’s microphone into a sophisticated recording device. Using this flaw an attacker can eavesdrop on conversations remotely.
5th year PhD candidate Ang Cui and Columbia Professor Sal Stolfo discovered the flaw while working on a U.S. Defense Department grant for the Defense Advanced Research Projects Agency. According to the researchers, they can remotely command a hacked phone to do anything they want.
For example, they say they can activate a webcam on a phone or instruct the phone’s LED light to remain off when the phone’s microphone has been activated. This way the eavesdropping victim won’t be alerted when their conversation is being recorded.
