When you think of security vulnerabilities, you think about things like browsers and smartphones. But with the Internet of Things, all kinds of things can get infected. including Fitbits.
“The malware could spread to your PC/Laptop if you’re using the syncing dongle, or to other Fitbit trackers. From what I’ve read of it though, it’s mostly theoretical. It could work under some circumstances, but there’s no real live code out there infecting Fitbit devices and spreading itself.” Since we’ve already had a refrigerator sending spam, I don’t think it’ll be long before someone makes something out of this.
