Fitbit Spyware Steals Personal Data via Watch Face
Immersive Labs Researcher takes advantage of lax Fitbit privacy controls to build a malicious spyware watch face.
A wide-open app-building API would allow an attacker to build a malicious application that could access Fitbit user data, and send it to any server.
Kev Breen, director of cyber threat research for Immersive Labs, created a proof-of-concept for just that scenario, after realizing that Fitbit devices are loaded with sensitive personal data.
“Essentially, [the developer API] could send device type, location and user information including gender, age, height, heart rate and weight,” Breen explained. “It could also access calendar information. While this doesn’t include PII profile data, the calendar invites could expose additional information such as names and locations.”
