Description

In the past six months, Coalfire has seen an increase in businesses receiving fraudulent emails from legitimate client accounts with fraudulent invoice attachments. In several cases, the recipient paid the invoices not realizing they were fraudulent. The losses have ranged between thousands and hundreds of thousands of dollars. When the business investigated, they found that the mailbox associated with the sender's account did not contain the sent emails. Moreover, the authorized user claims they never sent the email.
