We have recently learned that several states may have been defrauded by a scheme involving Automated Clearing House (ACH) payments to vendors. One state lost approximately $2 million as a result of the scheme. The affected states received documents from the fraud perpetrators requesting changes to vendor bank account information. Once the bank account information was changed in the state’s accounting system, payments for legitimate services were electronically sent to the new (fraudulent) bank account. The perpetrators then transferred or withdrew the money from the bank account and disappeared. Because this type of fraud will likely be detected quickly by vendors who have not received payment, the frauds are occurring for large vendors with recurring payments. In some instances, ACH payments into the fraudulent bank account have been stopped by the receiving bank’s fraud department. Other payments have been stopped because the state contacted the vendor directly to confirm the change in bank account information. Such controls discovered the fraud scheme.
