"He told us that the device just guessed what we were saying," she said. Danielle said the device did not audibly advise her it was preparing to send the recording, something it’s programmed to do. Is it possible there's an exploit out in the wild for these devices that allows an attacker to control the device remotely. Is it possible an attacker told the device not to make an audible announcement?
Is it possible that there's a remote exploit? Yeah of course but if it's in the wild enough that this particular individual was struck by a seemingly random (and valueless) attack we'd be seeing a lot more of these in the wild than we are.
