A customer in Mongolia was cheated out of $40,000 by a hacker impersonating one of their Chinese vendors. The hacker had been monitoring the customer and vendor's email communications. They intercepted an email from the vendor requesting final payment and changed the payment details to a new account number. The customer paid without realizing it was not the actual vendor. The real vendor then refused shipment since they did not receive payment. It will be difficult to pursue legally since the crime crossed multiple international borders. Companies are advised to publicly post any bank account changes on their websites to avoid similar scams.
