My LG C8, which I've done anything on with apps aside from installing Amazon, Youtube and Netflix (which I hope are "safe" and "reputable") is frequently trying to connect out with what appears to be a rootkit in Googling: > Threat Management Alert 1: A Network Trojan was Detected. Signature ET MALWARE Misspelled Mozilla User-Agent (Mozila). From: 192.168.1.x:46372, to: 23.52.164.68:80, protocol: TCP My firewall pick…

That's a really loose signature, it's just a misspelling which is actually pretty common in low-qa software that talks to the internet.

The dst IP in your alert is an akamai one according to centralops.

I tried to never connect my Smart TV to anything, but I realized one day (when someone's stuff was playing on it without me accepting any request...) it connected an open network in my residence. The only trick that worked to prevent it from connecting was putting the wrong password, and let it loop forever, trying to connect. Ugly.

I have an extra SSID which has no internet access and logs all of the things for exactly this reason.

Pick up anything interesting off your IoT and smart devices

I disabled WiFi on my Samsung TV after they were injecting ads into the home screen. Spend $800 to get ads served in their shitty/slow UI.

An acquaintance attempted that with Kindle, by keeping it in flight mode. After some days it popped up a message kindly asking to give it some network access. After a few more days it simply ignored the flight mode and connected to get fresh ads. Edit: I've checked with my wife who has an ad supported Kindle for over a year and keeps it in flight mode for months at a time. It never did that to her. So either Amazon c…

Yeah that's gross. Btw, Amazon does sell some cheaper ebook readers on the understanding that they will show ads. Was that the case here?

How would encryption help in this case? If the TV connects to open wifi opportunistically it will still be sending data to the internet you don't want it to, encrypted or not.

I think he may have meant that if all available APs are using encryption, then you don't have to worry about your TV automatically connecting.

Yeah I guess that makes sense. But a neighbor that turns on an open wifi hotspot would be all it takes for the TV to connect for a bit.

It's not something that should just be left up to chance, but I also don't know of a good solution other than regulation.

That is surprising. I've had my Kindles on airplane mode for up to a year and haven't received any notices like that.

> It's surprising to me that you can't find a single medium or high-ish end TV without smart features for a while you couldn't find a tv with decent features that wasn't 3d. happy to see that trend be over. unfortunately, it seems that industrial tv panels seem to be going away as well.

> for a while you couldn't find a tv with decent features that wasn't 3d. happy to see that trend be over. Huh, why would one avoid TVs that have 3D?

About a third of the population, myself included, can't really watch 3d movies on flat screens (hardwired focus to crossing in the brain). Having all the marketing try very hard to shove into my face a feature that literally gives me a headache was a nuisance.

My network is setup like this. It is really easy to do if you have a good router/AP, but most consumer routers, especially the ones provided by ISPs, are not vlan aware.

Is it specific to the router? I've got a Ubiquiti Amplifi and I'm not totally sure of the proper way to do this.

Usually you define the vlan on your router/switches and then link a SSID to that vlan on your AP(s). Exact steps differ significantly between vendors.

Do you have a real source for this? That’s a pretty serious accusation.

I'm guessing it's an ad supported kindle. The user paid less on the agreement that they would see ads. My non-ad supported kindle has never done anything like this.
