> update The FBI appears to have begun using a novel form of
> electronic surveillance in criminal investigations: remotely
> activating a mobile phone's microphone and using it to eavesdrop on
> nearby conversations.
> The technique is called a "roving bug," and was approved by top
> U.S. Department of Justice officials for use against members of a
> New York organized crime family who were wary of conventional
> surveillance techniques such as tailing a suspect or wiretapping him.
> 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 mobile
> providers can "remotely install a piece of software on to any
> handset, without the owner's knowledge, 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.
