Don't be too quick to toss out that wearable, though. Open Effect notes that the Apple Watch is truly secure based on its testing methods, and devices like the Fitbit Charge HR and Mio Fuse are safer than most. Also, these brands aren't necessarily turning a deaf ear. Fitbit, Intel (creator of the Basis Peak) and Mio have all talked to the researchers, and it won't be surprising if the companies tighten up their security through updates and future products.

As it stands, it's important to put these vulnerabilities in context. While there are real risks here, the likelihood of someone targeting your fitness tracker is fairly slim -- a hacker is more likely to want your banking info or phone location than your step count or heart rate. Still, these findings could help if you're concerned that any significant security flaw is one too many.
