Fit soldiers = Fitness Apps = Massive security leak

Australian student Nathan Ruser noticed that trails from Strava users in certain countries made it possible to identify military bases and other facilities operated by countries, including the U.S., in locations such as Afghanistan, Iraq, Somalia and Syria.

Strava released their global heatmap. 13 trillion GPS points from their users (turning off data sharing is an option). It looks very pretty, but not amazing for Op-Sec. US Bases are clearly identifiable and mappable.

Fit soldiers jog around. They use fitness apps. Fitness apps publishing GPS data becomes a big security leak.
