Yes, an alarmist article that fails to mention that most hackers are interested in finding honey-holes, and that honey is related to your PC/Mac or portable device, not the TV and certainly not the DVR. In fact, it is far easier and profitable for hackers to just hang-out at places with free WiFi and catch all the unsecured traffic from all those users who absolutely no clue that they are being reamed. In fact, this and all the unsecured traffic on portable devices is of far more concern and should be hyped, but it's more sexy to publish an article with the arcane attribute of seeing us in our skivvies while we watch TV. The hack for doing the same, but on our PC/Mac cameras has far more chances for creepiness and violations of privacy than a Samsung Smart TV.
However, the article is a good example of how still, with all our knowledge and legacy of poor security or no security built in to our technology, we are STILL producing tech with horrid security, and being behind a router isn't going to help if you are tricked into specifically requesting those packets. From car fobs to smart TV, more holes in the Swiss cheese than ever. But I aint losing any sleep over the Smart TV hole. Who the heck uses those things for serious internet surfing and buying? Exactly why serious evil hackers aren't interested in going there.
