Fitness trackers and other digital wearables have unlocked a new era of convenience and engagement in consumer health. Beyond general fitness trackers, you can find wearables for a variety of purposes; some help diabetics, some monitor for seizure activity, and some can aid in senior citizens’ health and quality of life. But the convenience of an interconnected lifestyle may be a double-edged sword. Fitness trackers and wearables are notoriously unsecured. Wearables record and store some of our most sensitive health data—which is often 10x more valuable than a stolen credit card— making them a particularly attractive target for hackers.
So what types of data does your fitness tracker store? For a start, it holds the identifying information required to set up your account, such as your email, username, and password. But other fitness tracking specifics can make a user easier to identify, including as gender, birthdate, geographical location, height, and weight. Health and activity data provides an in-depth look at the user’s daily habits through the power of GPS monitoring. If your device is paired inside of a network, other personal device information will also be stored, such as your Unique Device IDs or MAC addresses. Depending on the device, your wearables may also store your credit card information or bank account information.
New vulnerabilities
Because of their versatility, wearables and fitness trackers leave us vulnerable in many ways. In last year’s MyFitnessPal hack, which affected 150 million users, attackers hoped to access credit card information but came away with only usernames and passwords. But what about the information that is more specific to wearables, like GPS tracking? After the fitness tracker Strava revealed hidden army bases through heatmap tracking, the Pentagon began to restrict the use of wearables by military personnel due to the potential security threat. And the recently uncovered MiSafe vulnerability left thousands of children unsecured, allowing hackers to track their movements, listen in on conversations, and actually call children on their smart watches.
Even with these concerns, the wearables market continues to grow, with the prevalence of such devices predicted to double by 2021. Large healthcare organizations and insurance carriers are also starting to use insights from fitness trackers to influence both patient care and insurance rates. We’re even beginning to see the introduction of wearables for employee tracking, although this has met with mixed response. With this increased exposure to potentially insecure technologies, you’ll need to take extra steps to ensure your family’s security.
Where to start
Always research any fitness trackers or wearable devices before you commit, and be sure to avoid devices with any known security flaws. Notable examples to avoid are Medion’s Life S2000 Activity Tracker and Moov’s Now tracker. The Life S2000 requires no authentication and sends data unencrypted, and the Now tracker can leave users vulnerable to attack via Bluetooth connectivity. Even larger brands like Lenovo struggle to maintain an adequate level of security in their fitness trackers; the Lenovo HW01 smart band sends both registration and login data to its servers unencrypted.
Although it’s tedious, we recommend you always read the privacy policy of any wearable device or fitness tracking app before you use it. If the data storage and security measures outlined in the policy aren’t up to snuff, request a refund and let the manufacturer know why. Periodically reviewing your app’s privacy settings on your phone is also a good practice—just to make sure you’re comfortable with the app’s level of access. Take common-sense cybersecurity measures to help keep your wearables as secure as possible. Never reuse passwords or use third party login services like Facebook Login, and consider using a password manager like LastPass® instead.
Wearables and fitness trackers are here to stay, and the Internet of Things (IOT) is only going to keep growing. We have to work together to protect ourselves as we integrate these technologies into our daily lives. After all, the price of convenience cannot match the value of our personal security.
