Someone is spying on cellphones in the nation's capital..
A CBC/Radio-Canada investigation has found cellphone trackers at work near Parliament Hill and embassies.
A months-long CBC News/Radio-Canada investigation has revealed that someone is using devices that track and spy on cellphones in the area around Parliament Hill.
The devices are known as IMSI catchers and have been used by Canadian police and security authorities, foreign intelligence and even organized crime.
The devices, sometimes known by the brand name of one model, StingRay, work by mimicking a cellphone tower to interact with nearby phones and read the unique ID associated with the phone — the International Mobile Subscriber Identity, or IMSI.
That number can then be used to track the phone and by extension the phone's user. In some instances, IMSI catchers can even be used to gain access to a phone's text messages and listen in on calls.
