A new attack that uses terrestrial radio signals to hack a wide range of Smart TVs raises an unsettling prospect—the ability of hackers to take complete control of a large number of sets at once without having physical access to any of them.

The proof-of-concept exploit uses a low-cost transmitter to embed malicious commands into a rogue TV signal. That signal is then broadcast to nearby devices. It worked against two fully updated TV models made by Samsung. By exploiting two known security flaws in the Web browsers running in the background, the attack was able to gain highly privileged root access to the TVs. By revising the attack to target similar browser bugs found in other sets, the technique would likely work on a much wider range of TVs.

Discussion

1) Is there any way to make a connected piece of electronics secure from hacking?

2) Is it ethical, or even a good idea, to post how to hack a TV here?
