Smartwatches can be a perfectly useful and handy wearable device for some users, but it’s good to keep in mind that using them might mean opening yourself to an additional line of attack.
As student Tony Beltramelli has demonstrated for his Master’s thesis, it’s possible for an attacker to trick the user into installing a malicious app on his or her smartwatch (in his example Sony SmartWatch 3) that would record gyroscope and accelerometer sensor data, and send it to a server controlled by the attacker.
