fuckin hell I knew I wasn't the only one who covered their cameras but is it really this bad? Like I cover my phone front cam too just cuz I remember an incident where I got a virus on my old laptop which brought up a fake fbi thing that locked my PC and asked for £200 ransom. But it also showed me my webcam and it scarred me for life legit. Can they really just record from ur cameras?

As far as I know, they can record from your camera but need access to your OS to do it. You'd have to have a virus or something at that point. 

Like if you're just visiting a website and haven't downloaded or clicked anything weird, they can't really do much. Even with your credentials leaked, they can't just hack into your PC remotely, they'd need software installed AFAIK. I'm not a cyber security expert though. Just a web developer and we can't just get to your camera without proper permissions. It'll get denied by system security. We can try to access it but unless you click allow, nothing will happen.

I'm sure phone could happen too but I personally haven't run into it and don't cover that one. I just use private browsing and don't look at any weird sites I don't trust. Also if you think about it, if you're having some personal time on your phone, you're likely holding it up to your face and that's all anyone would see if they were on your camera somehow lol.

Edit: Also forgot to add, they could probably try to access your camera and try to trick you into clicking "allow" or whatever somehow.
