Is fitness tracker Strava revealing sensitive military locations and activities?

It was November when fitness-tracking company Strava first uploaded an updated version of a showing the physical activity of users around the globe.

But it wasn’t until Saturday when the controversy about it started to ignite.

That’s when Australian Nathan Ruser, who’s studying international security and the Middle East, decided to zoom in on Syria and . “I wondered, does it show US soldiers?” Ruser . “It sort of lit up like a Christmas tree.”

That got military experts, soldiers and much of the internet scouring the map to look for 유켄영국유학 evidence of their activity and wondering if the release of such sensitive location and activity information may have been a military security oversight.

But “recent data releases emphasize the need for situational awareness when members of the military share personal information,” she said. “DoD takes matters like these very seriously and is reviewing the situation to determine if any additional training or guidance is required.”

San Francisco-based Strava, which calls itself “The Social Network for Athletes” says it has 27 million users around the world who access the app through fitness devices such as Fitbit and Jawbone. Some users subscribe directly to its mobile app. The map shows 1 billion activities from all Strava data from 2015 through September 2017.
