Mobile Iron research director Michael Raggo told the BSides San Francisco conference the watch is a threat to individual and enterprise security.

“We ran dynamic and behavioural analysis (on the pairing app) and discovered that when it was paired, it started communicating outbound over a random IP address to China,” Raggo said.

Buyers may have gotten a slight clue that it wasn’t the most secure device in the world when they were advised to download a pairing app from an IP address handwritten on a piece of paper that comes with the u8 watch.

It does, though, underline the risks of putting your data onto a device purchased from an unknown brand. You can watch a video of the presentation below.
