Security Hole in Samsung Smart TVs Could Allow Remote Spying
The company that made headlines in October for publicizing zero day holes in SCADA products now says it has uncovered a remotely exploitable security hole in Samsung Smart TVs. If left unpatched, the vulnerability could allow hackers to make off with owners’ social media credentials and even to spy on those watching the TV using compatible video cameras and microphones.
In an e-mail exchange with Security Ledger, the Malta-based firm said that the previously unknown (“zero day”) hole affects Samsung Smart TVs running the latest version of the company’s Linux-based firmware. It could give an attacker the ability to access any file available on the remote device, as well as external devices (such as USB drives) connected to the TV. And, in a Orwellian twist, the hole could be used to access cameras and microphones attached to the Smart TVs, giving remote attacker the ability to spy on those viewing a compromised set.
Currently, the Smart TVs offer no native security features, such as a firewall, user authentication or application whitelisting. More critically: there is no independent software update capability, meaning that, barring a firmware update from Samsung, the exploitable hole can’t be patched without “voiding the device’s warranty and using other exploits
,” ReVuln said.
The company posted a video of an attack on a Samsung TV LED 3D Smart TV online. It shows an attacker gaining shell access to the TV, copying the contents of its hard drive to an external device and mounting them on a local drive, providing access to photos, documents and other content. ReVuln said an attacker would also be able to lift credentials from any social networks or other online services accessed from the device.
