"It turns out that some smart TVs are a little too smart for their own good--and the good of users. Some specific models of Samsung TVs that have Wi-Fi and other advanced capabilities have a flaw that enables an attacker to take a variety of actions on the TV, including accessing potentially sensitive data, remote files and information, the drive image and eventually gain root access to the device.

The issue affects many Samsung TVs, and the researcher who discovered the problem found that he could remotely access the remote control for the TV, retrieve files located on any USB drive attached to the TV and even install malicious software on the TV. Samsung produces a line TVs that have a variety of advanced capabilities, including the ability install apps such as Pandora, Skype and others. The TVs can be controlled by voice commands and by apps running on some Samsung phones and tablets.

And now, they also can be controlled by attackers."
