MasterCard has admitted that a security breach last week allowed fraudsters to steal credit cardholders’ details.
The incident is believed to have affected up to 2,000 cardholders with accounts at the Clydesdale Bank and other banking firms.
Neither MasterCard nor Clydesdale Bank would confirm how many customers had been hit by the fraudsters or any other details of the incident.
In a statement, MasterCard said it had “been made aware of this breach and took immediate action together with the banks concerned”.
A spokesperson for Clydesdale Bank said, “MasterCard made us aware of this breach and we have taken appropriate action.”
MasterCard added, “In order to protect cardholders, MasterCard and its card-issuing banks operate state-of-the-art, multilevel fraud monitoring systems. Together, we look for patterns of activity consistent with fraud. Issuers can then monitor their cardholders’ accounts closely for fraudulent activity, and may reissue cards or take other actions if they suspect fraud has occurred.
“MasterCard International is concerned whenever cardholders are inconvenienced. As usual, if a MasterCard cardholder is concerned about their individual account, they should contact their issuing financial institution.”
