Mastercard says it expects to be able to discover that your credit or debit card number has been compromised well before it ends up in the hands of a cybercriminal
FILE - A sign indicating MasterCard credit cards are accepted is posted at a New York business, Jan. 21, 2015. Mastercard said Wednesday, May 21, 2024, that it expects to be able to discover that your credit or debit card number has been compromised well before it ends up in the hands of a cybercriminal. Mastercard said Wednesday that it expects to be able to discover that your credit or debit card number has been compromised well before it ends up in the hands of a cybercriminal.
Mastercard, which is based in Purchase, New York, says with this new update it can use other patterns or contextual information, such as geography, time and addresses, and combine it with incomplete but compromised credit card numbers that appear in databases to get to the cardholders sooner to replace the bad card.
These compromised cards can remain undetected for weeks, months or even years. It is only when the payment networks themselves dive into the dark web to fish for stolen numbers themselves, a merchant learns about a breach, or the card gets used by a criminal do the payments networks and banks figure out a batch of cards might be compromised.
