I’ve also seen some very convincing email phishing in the last few weeks with spoofed email headers. It’s made it challenging for my email spam filter to weed out the fakes. I think the best I can do at this point is to never trust these phone calls or email even if it seems to be coming from legitimate sources. It is best to visit the website of the bank or call the numbers on the back of the card. The risk are too high.
Vishing is getting more sophisticated.
