One can never be too careful to the point of paranoia. I also make it a point of duty to check the first three or four alphabets in the address I'm sending to, then the middle and end alphabets. I try as much as I can never to be in a hurry while on a financial transaction. With cryptos, I triple check. No hurry in life. Going forward, I think people should restrict links they click for a lot of these malware come from sites we visit, especially porn sites.
I tend to agree, but really it should be balanced. I've had this issue myself where I tend to look at things from a paranoid perspective, but then it isn't always rational to look at things that way. It usually means you're doing additional steps when it really isn't needed.
Personally, I recommend everyone picks a certain threat model (i.e personally defined strictness), and stick to it strictly.
I'm curious why we don't have such with mobile phones since we also have clipboards with phones.
I find it mind boggling that Android hasn't implemented a permission based system for accessing the clipboard, because it already has the fundamentals there. Especially, when a clipboard could be considered on of the biggest security flaws that users will fall victim to.
I think such malicious trick is possible on mobile phones by downloading a third-party keyboard, they always ask for some access that you don't want to accept, I find such keyboards unsafe to use.
