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 surveillance technique came to light in an opinion published this week by U.S. District Judge Lewis Kaplan. He ruled that the “roving bug” was legal because federal wiretapping law is broad enough to permit eavesdropping even of conversations that take place near a suspect’s cell phone.
Covert listening device
A covert listening device, more commonly known as a bug or a wire, is usually a combination of a miniature radio transmitter with a microphone. The use of bugs, called bugging, is a common technique in surveillance, espionage and in police investigations.
A bug does not have to be a device specifically designed for the purpose of eavesdropping. For instance, with the right equipment, it is possible to remotely activate the microphone of cellular phones, even when a call is not being made, to listen to conversations in the vicinity of the phone.
Remotely activated mobile phone microphones
Mobile phone (cell phone) microphones can be activated remotely, without any need for physical access.This “roving bug” feature has been used by law enforcement agencies and intelligence services to listen in on nearby conversations. A United States court ruled in 1988 that a similar technique used by the FBI against reputed former Gulfport, Mississippi cocaine dealers after having obtained a court order was permissible.
Automobile computer systems
In 2003 the FBI obtained a court order to surreptitiously listen in on conversations in a car, through the car’s built-in emergency and tracking security system. A panel of the 9th Circuit Court of Appeals prohibited the use of this technique because it involved deactivating the device’s security features.
Proof of This theory
- Embassies and other diplomatic posts are often the targets of bugging operations.
- The Soviet embassy in Ottawa was bugged by the Canadian government and MI5 during its construction.
- Extensive bugging of the West German embassy in Moscow by the KGB was discovered by German engineer Horst Schwirkmann, leading to an attack on Schwirkmann in 1964.
- The Great Seal bug was hidden in a copy of the Great Seal of the United States, presented by the Soviet Union to the United States ambassador in Moscow in 1946 (not discovered until 1952). The bug was unusual in that it had no power source or transmitter, making it much harder to detect – it was a new type of device, called a passive resonant cavity bug. The cavity had a metallic diaphragm that moved in unison with sound waves from a conversation in the room. When illuminated by a radio beam from a remote location, the cavity would return a frequency modulated signal.
- The United States Embassy in Moscow was bugged during its construction in the 1970s by Soviet agents posing as laborers.
- In 1990, it was reported that the embassy of the People’s Republic of China in Canberra, Australia, had been bugged by the Australian Secret Intelligence Service as part of the UKUSA Project Echelon.FOR MORE DETAILS PLS VISIT : www.rovingbug.in
