Pierre Barre with Chaouki Kasmi and Thomas Sabono from DarkMatter, presented new security weakness in smart TVs during Hack in the Box Dubai 2018
TVs can be found everywhere and their security is very problematic. They can be (ab)used by attackers in order to enter into airgapped networks and attack routers, IP phones and internal servers.
During a live demo, it has been demonstrated that it is possible to take over remote cameras using the DVB-T communication channel (without access to the LAN/Wifi). Also 0days vulnerabilities in Smart TVs have been found.
One of the solution is to not connect TVs to networks (LAN or Wifi) and desactivate everything so the smart TV will become a “dumb” display.
