Marcus Thomas, a former assistant director of the FBI's Operational Technology Division in Quantico, Virginia, tells the Washington Post that the FBI could spy on anyone's webcam without turning on the camera's indicator light.
Szymon Sidor is a Polish-born software engineering genius currently working for Dropbox as an intern.
Before that, he served two internships with Google working on Google Chrome and Google Analytics.
He is working on his Ph D at MIT and writes a blog called Snacks for Your Mind.
Sidor's latest "snack" is a demonstration of how the cameras on your Android Smartphone can be turned on without you knowing it, and sequential photos sent to a third party over the Internet.
Spying through smartphone cameras, computer webcams, laptops and tablets is widespread and governments have been checking people out for years.
Between 20, GCHQ, Britain's NSA, ran a program called Optic Nerve that scanned live webcam chats on Yahoo (and probably other chat services).
Many of the images obtained were very personal ones and could be used to either embarrass or blackmail users.
Reports in the UK say that NSA engineers helped GCHQ develop the Optic Nerve program.
Many have either claimed or speculated that one way the NSA and other U. spy agencies got around the prohibition of spying on Americans was to let a third party do it for them. News reports, based on the leaks of NSA information by Edward Snowden, say that GCHQ stored millions of images gleaned from its webcam surveillance.
