Simple Steps to Prevent Fraudulently Induced Wire Transfers Email communication is efficient, but it is not a secure method of communication. Regardless of your familiarity with a contact, that contact’s email may be intercepted, altered and fabricated.You may reduce the chances of fraud by following these best practices:

| 1. | Verify Email Requests by Telephone: Require those responsible for paying invoices or changing bank                                                                                                         
 routing information to verify payment details over the phone, rather than by email or documents sent electronically. Making a phone call to a known, pre-existing telephone number remains the single best 
 protection against fraud.                                                                                                                                                                                  |

 people to review and approve wire transfer requests, pay an invoice or change a business partner’s bank account information. Such requests should be entered by the initiator of the wire and verified by two independent signatories. |

| 3. | Turn on MFA for Cloud Email: Multifactor Authentication is available from all major email providers.
