This is one that could make James Bond's "Q" a bit jealous.
Researchers at the Naval Surface Warfare Center in Crane, Indiana, and Indiana University Bloomington, have developed malware that can be used to hijack a smartphone's camera.

Consequently, victims of this scenario would be providing a view of their location along with any personal information in it like passwords and account information. More below:

While there is probably more hype than truth to that thought, one thing is certain. We are just beginning to learn all the ways that sensors in smartphones can be used for purposes that are good, or bad.
