Corcoran said someone acting as her assistant sent an invoice to her bookkeeper earlier this week for a renovation payment. She told People that she had "no reason to be suspicious" about the email because she invests in real estate, so the bookkeeper wired $388,700 to the email address.
The problem was that the email address didn't belong to her assistant. The scammer imitated her assistant's email address and misspelled it with one letter.
