Attack Surface - LAN
0Most of the SmartTV issues are related to services exposed via LAN:
0UPNP
0Video/Audio service (like DirectFB)
0Various HTTP/HTTPS servers
0Network remote controller
0Media sharing
0Status and information
0First thing to try on your SmartTV is using NMAP:
0You will see a number of different TCP and UDP ports open
0Some of them awaiting for you to connect :]
0If you try to send some junk data to these ports you might get some easy way to
crash/reboot the TV, a starting point to investigate
0The TV also scans the LAN, an attacker can passively exploit vulnerabilities
