The new hack shows that the attacker does not need to have physical proximity to the smart TV.
The technique is known to work against two fully updated TV models made by Samsung.
It harmonizes classic broadcast, IPTV, and broadband delivery systems.
TV transmission signal tools like DVB-T, DVB-C, or IPTV all support HbbTV.
As a result, the attacker can only be caught transmitting the signals in real-time.
Also, any backdoor created using this method is almost impossible to remove.
In Scheels testing, a factory reset of the TV didnt remove his access to it.
Check out the video below that includes demonstrations for both DVB-T attacks and proposed mitigations.
