The development and sudden boom in IoT equipment in the healthcare sector have resulted in the surge of cyber attacks. The use of wearable equipment such as health trackers and fitness bands has recently grown common. The safety and security features of these fitness trackers are an ongoing worry since they have a lot of important information about the user. 

Recently, 16.18 GB of unencrypted database disclosing over 61 million records of users stored in their fitness wearables was identified in the latest security analysis at WebsitePlanet. A substantial percentage of disclosed records were all related to IoT fitness and health monitoring devices. 

Following additional research, several references were made to "GetHealth," a New York City-based firm that claims a unified solution for hundreds of wearables, healthcare devices, and apps to access health and wellness data. The GetHealth database was not encrypted by default and allows easy accessibility for everyone. After researchers have notified GetHealth, the database is now encrypted. 

GetHealth platform can synchronize health-related information from a multitude of sources, such as Fitbit, Misfit Wearables, Microsoft Band, Strava, Google Fit, 23andMe, Daily Mile, FatSecret, Jawbone UP, Life Fitness, MapMyFitness, MapMyWalk, Moves App, PredictBGL, Runkeeper, Sony Lifelog, Strava, VitaDock, Withings, Apple HealthKit, Android Sensor, and S Health.

Plenty of the information leaked comprised the first and last names of users, date of birth, body weight, height, sex, geolocation, etc. “This information was in plain text while there was an ID that appeared to be encrypted. The geolocation was structured as in America/New_York, Europe/Dublin and revealed that users were located all over the world,” WebsitePlanet said. 

Whereas the researchers analyzed a sample of 20,000 records, the majority of leaked data were from Fitbit (2.766 times) as well as from Apple HealthKit (17,764). This security flaw affects a majority of the customers of Apple Healthkit because Healthkit gathers deeper health information than any other instruments or applications, like blood pressure, body weight, sleep levels, and blood glucose. 

Fitness trackers are equipped with vital information to monitor the user's health. This might also lead to several privacy problems, regrettably. The confidential material of users is a financial enterprise for individuals in charge of threats. In tailored phishing attacks, identity thefts, or social engineering attacks, the data may be abused by cybercriminals. 

“This case sets an example of how lack of care with sensitive data can make risks escalate indefinitely, as millions of people were exposed simply by wearing tracking devices during their workout sessions,” WebsitePlanet added.
