Cybersecurity has been at the forefront of the defense discussion for years now, but it seems that the basic premise still eludes many working within the nation’s defense apparatus. A recent report made by the Dutch newspaper De Correspondent shows that the use of the activity tracker smartphone application “Polar” by members of the U.S. Secret Service, NSA, the U.K.’s MI6 and a host of others publicly reveals their exact movements and locations. In some instances, the app offers detailed routes of running courses in and around foreign military installations. In others, it offers up the identities and home addresses of personnel working within military and intelligence installations here at home.

The report states:

Polar is not only revealing the heart rates, routes, dates, time, duration, and pace of exercises carried out by individuals at military sites, but also revealing the same information from what are likely their homes as well. Tracing all of this information is very simple through the site: find a military base, select an exercise published there to identify the attached profile, and see where else this person has exercised. As people tend to turn their fitness trackers on/off when leaving or entering their homes, they unwittingly mark their houses on the map.”

The application itself encourages users to link their profiles to a Facebook account, list their first and last names, and include profile pictures so they can interact and compete with other fitness enthusiasts in the area. However, from an intelligence standpoint, that’s all actionable — using a combination of social media and Google maps, it becomes fairly easy to identify individuals that work within the national defense and intelligence sectors, and use their posted workouts to find their homes or identify high traffic regions of military installations.
