Devices that track, spy on cellphones found at Montreal's Trudeau airport

If you were recently at Montreal's Trudeau International Airport, someone may have been spying on your cellphone.

A Radio-Canada reporter detected the presence of an electronic surveillance deviceknown as anIMSIcatcher on Feb. 21, whilewaiting for a U.S.-bound flight.

The revelation comes afterajoint CBC/Radio-Canada investigation earlier this week found electronic surveillanceIMSI catchers have been used in the area near Parliament Hill in Ottawa.

The devices, sometimes known by the brand name of one model,StingRay, mimic acellphonetower to interact with nearby phones and read the unique ID associated with a phone the International Mobile Subscriber Identity.

They have been used by Canadian police and security authorities, foreign intelligence and even organized crime.

At Trudeau airport, Radio-Canada detected the catcher's presence through the use of a CryptoPhone a cellphone look-alike that emits red alerts when a fake antenna tries to catch its signal.

Several red alerts were received, throughout the afternoon and early evening, in the section of the airport for U.S. departures.

Conversations listened to in real time?

ESD America, the U.S. supplier of the CryptoPhone, whichspecializes in counterintelligence, analyzed the alerts.

"The IMSI catcher that you were connected to was tracking the phone but almost likely had the ability to listen to calls," said Les Goldsmith, CEO of Las Vegas-based ESD America.

Goldsmith added that that specific model of the IMSI catcher could probably listen to calls in real time.

The alerts recorded by the CryptoPhone at the airport indicate, among other things, that the system that allows the phone to encrypt conversations had been disabled.

When asked who could possess that kind of equipment, Goldsmith toldRadio-Canada, "Your government, or any other government."

Goldsmith also said that if the data on our phones wereintercepted that day by an IMSI catcher at the airport, the same goes for all other mobile phones in the vicinity.

IMSI catchers can cover a half-kilometre radius in urban areas and a two-kilometre radius in open spaces.

Another security expert, who comes from a federal agency and whose identityRadio-Canada has agreed to protect, believes that various organizations could have deployed this IMSI catcher.

"The Montreal police covers Trudeauairport. The RCMP and CSIS[Canadian Security Intelligence Service]are also there," he said. "If you're trying to identify the presence of a targeted individual, it's plausible to do it with that equipment in a specific place like the Montreal airport.

"U.S. customs officers also have a fair presence at the airport. It would not surprise me at all that they too have deployed something like that."

Who is spying at Trudeauairport?

Radio-Canada could not uncover who deployed the IMSI catcher at Trudeauairport on Feb. 21.

Police and intelligence agencies refuse to talk about their investigative techniques.

However, Quebec's provincial police, theSretduQubec,said that it does not have an IMSI interceptor, but it refusesto say whether it uses the interceptor of other police forces.

The U.S. Embassy refused to comment.

Meanwhile, Aroports de Montral, the corporation that runs the airport, said it does not use an IMSI catcher.

Radio-Canada got the same response from Transport Canada. The federal department added that"we do not know which organization, if any, would have used an IMSI catcher."
