UPDATE: FitBit Reassures Data Security Over Bluetooth Hack Presentation

Updated (11/23/2015): Earlier, a security researcher recently revealed that the technology in sports wearable FitBit is susceptible to hacking and system infection. Forbes said Axelle Apvrille of Fortinet showed the findings at the Hack.Lu tech conference about FitBit Flex’s high exposure risk to malware via its Bluetooth radio. 

Apvrille disclosed to Endgadget that a bad actor could infect the wearable in less than 10 seconds. She added, “"You don't need physical access (to the tracker), but you do need to be close (Bluetooth range). It does not matter if it is paired (to another device) or not… An attacker sends an infected packet to a fitness tracker nearby at Bluetooth distance then the rest of the attack occurs by itself, without any special need for the attacker being near." 

FitBit has since issued out a statement about the findings. While the company had acknowledged Fortinet’s findings, it disputed the idea that anyone can hack the device using the Bluetooth radio feature. Moreover, Apvrville's test is purportedly a proof of concept and not an actual proof that the wearable is susceptible to hacking.  

“Since that time we’re maintained an open channel of communication with Fortinet. We have not seen any data to indicate that it is currently possible to use a tracker to distribute malware,” FitBit said.
