Samsung said it's making its smart TV app platform more secure after a vulnerability was discovered that could expose users' internet connections to outside sources. The security company said that installing the Pac-Man app can turn a smart TV into "a residential proxy exit node" at the flip of switch. TechCrunch contacted Samsung about the vulnerability; the tech giant responded by saying it would ban any apps that shared its users' internet connections. The Samsung spokesperson also told TechCrunch that it was going to implement "strict platform-wide developer policies explicitly banning residential proxy SDKs." Last month, LG said it would suspend any apps that can turn a customer's TV into a residential proxy, as reported by KrebsOnSecurity.
