Unfortunately this is a product not many care for nor know about, and I had a personal working relationship with this vendor, so even if it were “leaked anonymously” they could point back at me and make things a living hell.
At this point it’s been almost five years. They made their stance known. The exploit isn’t one that can be done completely remote without some internal knowledge to the setup of the equipment. It’s old news and they’re better off fading away in obscurity. I just won’t bother to try helping them make their products better and more secure.
I’ve jokingly said this before, but just wait until manufacturers start adding 4G/5G to TVs explicitly for ads and telemetry…
