Never click on a link that tells you to update Your banking information. If You think the bank is really contacting you then go to the bank’s site the same way You always do, never from the link that is in the email.
The scam is sending millions of emails all over the world with bank headers and logos on them to make them look like they are coming from Your bank. Lots of times it comes from a bank that You do not have an account with. but these criminals try the most popular banks in the regions where they think You are. If they so happen to get the bank name right, they have a much better chance of getting you to click on the update link.
