MasterCard Security Alert

MasterCard has alerted that some merchants have recently received fraudulent “MasterCard Security Alert” e-mail messages. These e-mails ask merchants to conduct payment card test transactions followed by a refund to a different payment card. These e-mails also instruct merchants to send the details of the transactions to an e-mail address not affiliated with MasterCard. This scam is being perpetrated by criminals in order to gain merchant transaction information so they can attempt to make fraudulent purchases and refunds using stolen payment card information.

If any business receives an unsolicited phone call, e-mail message, text message, or social media request from an individual claiming to be a MasterCard Security representative, do not to respond. Report the fraudulent inquiry to MasterCard using the following e-mail address: datasecurity@mastercard.com.
