Taas "spioneerivad": Seekord siis kirjutatakse ja näidatakse ka videot (teema sees siis link sellele videole).

Yes, your smartphone camera can be used to spy on you...

Yes, smartphone cameras can be used to spy on you - if you're not careful.

A researcher claims to have written an Android app that takes photos and videos using a smartphone camera, even while the screen is turned off - a pretty handy tool for a spy or a creepy stalker.

University student Szymon Sidor claimed in a blog post and a video that his Android app works by using a tiny preview screen - just 1 pixel x 1 pixel - to keep the camera running in the background.

Now that most smartphones come with a camera (or two), and camera use is popular with apps like Instagram that encourage photo sharing, it's a little surprising it has taken so long for hackers to find sneaky ways to exploit them.

Spyware of this sort has been around for a long time for Windows - the malware called Blackshades for example, which hackers have used to secretly record victims with their computer's webcam.

But this seems to be the first reported instance of an Android application that can hijack a smartphone or tablet's camera for the same devious purpose.

According to Sidor, the Android operating system won't allow the camera to record without running a preview - which is how Sidor discovered that he could make the preview so small that it is effectively invisible to the naked eye.

Sidor demonstrated how the app works in a video, using his Nexus 5 smartphone.
