Let's say I am using trust wallet now and I had to copy the last address I sent BTC to, the only way this can be possible is if.....
Clipboard malware is active, maybe while copy pasting the clipboard hijack malware switch the copied address to another.
Or some form of permission is been asked by the attacker, after you as the wallet owner clicked on a link, can someone please explain this to me or something.
If I understood correctly, I believe there is another way to achieve this where the scammer uses the dusting attack! He just needs to generate a vanity address matching the victims address and send a tiny amount of cryptocurrency (a dusting transaction) from this vanity address. And later if the user isn't careful enough and copies address from previous transactions history, then there is a good chance that he might end up copying the scammers address and send the funds to the wrong address without even realizing it.
