Several hundred thousand cards have been stolen, and this data can be used to make purchases. In addition to credit card details, the leaked data also includes personal information such as name, address, and phone number. The information was accessed through breaches of companies that store credit card data. American Express was the biggest company affected, with more than 1.2 million cards compromised.

If you have an old credit card, consider switching to a different one. These days, many banks are competing with each other, and the rewards on newer cards are higher than they were in years past. Moreover, if you're not using your card enough, you might want to consider canceling it. This way, you won't have to pay any fees for using your credit card. Also, dumping your credit card can help your credit score.
