Cyber intelligence company purchases physical location data to resell to governments

Israeli firm Rayzone Group was found to purchase cellular users real-time location data and browsing habits through automated auctions for surveillance purposes, Bloomberg reports. Rayzone  purchases this location and browsing data, "feeds" it to a surveillance system called Echo and sells to governments to track individuals via their cellphones. Rayzone obtains data from advertising exchanges and companies that trade location and other mobile data. The company reportedly "posed as prospective advertisers to acquire data through a system known as a demand-side platform."
