Does Confirmation of Payee even exist outside the UK? Even if it did exist within other countries, I highly doubt there is international integration.

PSD3 covers international IBAN verification and will, thanks to regulation, ensure that this works cross-border. I think the technical aspects are fairly similar to CoP as we have it in the UK. Even in its absence though, the international payment flow puts enough friction into the process it would probably ring some alarm bells for a potential victim.
