I was so lucky to noticed this and I have the habit of cramming the last three alphabets of the receivers address after clicking on copy. May we not work for scammers to enjoy our hard work in the end.
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.
This malware has been known for a long time, and we call it in general
clipboard malware, and that's exactly what you described.
I'm curious why we don't have such with mobile phones since we also have clipboards with phones.
