The real story about fake email
In a sharing session with People magazine at the end of February 2020, with just a fake email, the fraudster stole nearly $ 400,000 of female billionaires participating in Shark Tank America. That is Mrs. Barbara Corcoran, one of the big investors of Shark Tank America.
The hacker sent her an email with a receipt requesting payment of the cost of a real estate remodeling activity. As usual, Barbara’s assistant would send the bill to the accountant. But that day, the billionaire did not pay close attention to the email address of the sender. She did not doubt the contents of the bill and the recipient’s bank account, because she had many investments in real estate.
Barbara’s accountant also received an email about the bill and she believes it is an email from Barbara’s assistant, so she spent the money on the bill.
No one noticed the anomaly until the accountant sent an email to the assistant’s real email address to announce the payment was completed. Barbara’s assistant was shocked to see her name in the email address. No one can see that there is an incorrect word on the email address of the assistant. That is a tactic commonly used by hackers.
