Destroy a Microphone (lemmy.ml)

During Prime Days I was dumb and bought some Chinese lamp because it was on sale. I gotta say, it’s actually awesome — with the app I can change colors, styles, and so on, and I really like it.

The account creation already bugged me, although I think it was only needed for the first startup. I deleted the account since then. The app is in deep sleep on my phone with zero permissions except Bluetooth.

What really bothers me, though, is the built-in microphone for voice commands — on a lamp! I don’t want someone listening to me. It’s too late to send it back, and I actually want to keep it.

Until now, I’ve just unplugged it from the outlet every time I don’t use it, but that’s very tedious. So, is there an easier way to completely disable the microphone? Does putting tape over it completely mute it? Or would I have to take it apart and desolder it — which I’m probably too lazy, impatient, and inexperienced to do? So is there maybe a smarter or brute force way to do it? im paranoid i dont want my fucking lamp listening to me. sometime i even turn of mic and cam acsess on my phone.

I had a similar incident with a cheap, 360, cam I bought off of Aliexpress. It was not going to be a security cam, just a cam to keep an eye on some seedlings in a grow box. I set it all up and would review the video of the seedlings sprouting. Then I noticed an weird behavior. At 5:00 AM it would automatically pan and stop, then repeat.

At the time we were experiencing some heavy electrical storms in our area and I have a Woody doll that sits up on a shelf in my lab. When we get electrical storms in this area, my Woody doll will introduce himself all on his own. 'Hey howdy hey! My name's Woody!' It'll freak you out if you didn't know it does that. The Woody doll has a pull string voicebox and I haven't pulled the string in years. I attribute the phenomenon to static charges in the air that activate the voicebox somehow.

So the panning I attributed to this static electrical charge during electrical storms. However, it started becoming a schedule. At 5:00 AM~ it would begin panning. So I got into the guts of the cam and the software. Turns out, no matter what DNS you used, one was already hard coded (1.2.4.8) along with other network settings, into the firmware and seemed to bypass any setting you punched in. The cam operated as a normal cam would and for what I was using it for, it did the job, except for the early morning panning.

So, great, I've allowed a nefarious actor into my network. I removed the cam off the wifi, and destroyed it. Combed through the network for any signs of exfiltration or other angles of attack and found nothing, except that I had pretty much set up a cheap, Trojan horse on my network.
