Chapter 1

What is Payment Fraud?

Payment fraud is a catch-all term that refers to the use of deception to carry out unauthorized financial transactions. Payment fraud may involve stolen credentials, impersonation, or embezzlement, and transactions may be conducted through credit card, debit card, wire transfer, ACH, check, or cash.

Regardless of the channels and tactics used, the aim is the same. Payment fraudsters are seeking to illegally enrich themselves at the expense of the victims they harm.

Common Payment Fraud Tactics

Payment fraud can take dozens of different forms. Common avenues of attack include account takeovers, where fraudsters initiate transactions after gaining unauthorized access to online accounts, and synthetic identity theft, where scammers use a combination of real and fake personally identifying information (PII) to sign up for bank or credit card accounts.

More sophisticated payment fraud tactics include clean fraud, business email compromise (BEC) attacks, and bust-out fraud. In these approaches, fraudsters either target victims with large asset bases or attempt to appear legitimate for an extended period of time.

Payment Fraud Statistics

Payment fraud results in billions of dollars of fraud losses per year. According to data from the Association of Certified Fraud Examiners, payment fraud causes businesses to lose roughly 5% of their revenue per year.
