Exercise-tracking app releases information on US, allied military bases

A map showing paths taken by users of an exercise tracking app reveals potentially sensitive information about American and allied military personnel in places including Iraq and Syria.

While some bases are well known to groups that might want to attack them, the map also shows what appear to be routes taken by forces moving outside of bases -- information that could be used in planning bombings or ambushes.

The map, made by Strava Labs, shows the movements of its app users around the world, indicating the intensity of travel along a given path -- a "direct visualization of Strava's global network of athletes," it says.

Routes are highlighted over large parts of some countries, but in others, specific locations stand out.

The map of Iraq is largely dark, indicating limited use of the Strava app, but a series of well-known military bases where American and allied forces have been deployed as part of war against the Islamic State (IS) group are highlighted in detail.

These include Taji north of Baghdad, Qayyarah south of Mosul, Speicher near Tikrit and Al-Asad in Anbar Province.

Smaller sites also appear on the map in northern and western Iraq, indicating the presence of other, lesser-known installations.

More dangerously, stretches of road are also highlighted, indicating that Strava users kept their devices on while travelling, potentially providing details about commonly-taken routes.

Opting out an option

In Afghanistan, Bagram Airfield north of Kabul is a hive of activity, as are several locations in the country's south and west.

Tobias Schneider, a security analyst who was among the group of people who highlighted the military bases shown on the map, noted that it shows military sites in Syria and Iraq as well as the Madama base used by French forces in Niger.

"In Syria, known Coalition (i.e. US) bases light up the night. Some light markers over known Russian positions, no notable colouring for Iranian bases," Schneider wrote on Twitter.

US forces are deployed in support of local forces battling IS in Syria as well as Iraq, while Russian and Iranian units are backing President Bashar al-Assad's government in the country's civil war.

"A lot of people are going to have to sit thru lectures come Monday morning," Schneider wrote, referring to soldiers likely to be taken to task for inadvertently revealing sensitive information while trying to keep in shape.

"Bases are fixed & hard to conceal," he wrote, so the "biggest potential threat is to tracking movement."

The Department of Defense said it is "reviewing" the situation.

"Recent data releases emphasize the need for situational awareness when members of the military share personal information," Major Audricia Harris, a Pentagon spokeswoman, said.

"DoD takes matters like these very seriously and is reviewing the situation to determine if any additional training or guidance is required, and if any additional policy must be developed to ensure the continued safety of DoD personnel at home and abroad."

The issue could have been fairly easily avoided. According to Strava, "athletes with the Metro/heatmap opt-out privacy setting have all data excluded" from the mapping project.
