An interactive map posted on the Internet that shows the whereabouts of people who use fitness devices such as Fitbit also reveals highly sensitive information about the location and activities of soldiers at U.S. military bases, in what appears to be a major security oversight.
The Global Heat Map, published by the GPS tracking company Strava, uses satellite information to map the location and movements of subscribers to the company’s fitness service over a two-year period, by illuminating areas of activity.
Strava says it has 27 million users around the world, including people who own widely available fitness devices such as Fitbit, Jawbone and Vitofit, as well as people who directly subscribe to its mobile phone application.

In warzones and deserts such as Iraq and Syria, the heatmap becomes almost entirely dark – except for a few scattered pinpricks of activity. Zooming in on those brings into focus the locations and outlines of known U.S. military bases, as well as of other unknown and potentially sensitive sites – presumably because U.S. soldiers and other personnel are using fitness trackers as they move around…
