How to keep your devices safe when you park at a trailhead

BlueBorne, as the researchers have dubbed their attack, is notable for its unusual reach and effectiveness. Virtually any Android, Linux, or Windows device that hasn't been recently patched and has Bluetooth turned on can be compromised by an attacking device within 32 feet. It doesn't require device users to click on any links, connect to a rogue Bluetooth device, or take any other action, short of leaving Bluetooth on. The exploit process is generally very fast, requiring no more than 10 seconds to complete, and it works even when the targeted device is already connected to another Bluetooth-enabled device.
