Twenty-year-old college student Nathan Ruser has an interest in the Syrian conflict and an affinity for maps.
It’s this combination that led him to discover the potential security risks posed by fitness app Strava.
On Saturday, the Australian came across a tweet of Strava’s global heatmap, which was originally published in November 2017. Ruser noticed lit up in areas in regions of Syria and the Sahara, often not occupied by civilians, that indicated the presence of security forces working out near military bases and other sensitive locations.
