Strava — a fitness app that links to smartphones and wearable fitness trackers to collect information about exercise habits — released a data visualization map of users' activity, which could reveal the location of secret U.S. military bases, the Guardian reports.

Why it matters: This is a significant security threat because it makes U.S. bases not only identifiable, but mappable to anyone who has access to this fitness app.
