Shark Tank‘s Barbara Corcoran is counting some losses as she just lost $400,000 in a phishing scam.

According to PEOPLE, her bookkeeper got an email about an invoice “approving the payment for a real estate renovation.” Corcoran told PEOPLE:

“I lost the $388,700 as a result of a fake email chain sent to my company,” Corcoran says. “It was an invoice supposedly sent by my assistant to my bookkeeper approving the payment for a real estate renovation. There was no reason to be suspicious as I invest in a lot of real estate.”

Her bookkeeper continued to make communication with who they thought was the assistant, sending the wire payment on Tuesday.

The error wasn’t noticed until the bookkeeper sent a follow-up email to the assistant’s real email address and telling them about the transaction that just took place. That’s when the company became aware of the scam and the assistant noticed her email had been altered and hacked. Corcoran

“The money was wired to the scammer yesterday and my bookkeeper copied my assistant, who was shocked to see her name on the correspondence. The detail that no one caught was that my assistant’s email address was misspelled by one letter, making it the fake email address set up by the scammers.”

But it was too late, as the money was untraceable and already gone from the account. However, Corcoran is keeping a good attitude about it:

“The scammer disappeared and I’m told that it’s a common practice, and I won’t be getting the money back. “I was upset at first, but then remembered it was only money.”
