It’s hard to fathom the extent of the Equifax data hack—millions of Social Security numbers were taken—and by now you’ve learned to monitor your credit and freeze your reports. Hackers don’t just have your personal info, though. They may have your credit card numbers, too.


Consumerist reminds us that 200,000 credit card numbers were taken in the hack, too:

Krebs on Security obtained a confidential alert that Visa and MasterCard sent to financial institutions, and the alert is pretty specific. Fraud alerts that go out to banks and other financial institutions after a payment data breach usually have incomplete information and can’t name specific customers, but for cards that the Equifax hackers took, the networks had more detail than that. The credit card networks know which customers’ cards were breached and shared that information with banks. They also were able to confirm the source that the numbers were taken from Equifax.


As the site points out, it’s easy to overlook this fact when we’ve had our most personal and vulnerable information stolen, but hackers may also have your credit card numbers and expiration dates, and that’s enough info to do damage.

So while you’re protecting yourself with credit monitoring, fraud alerts, and freezes, don’t forget to add “check credit card statements” to the mix and look out for any unauthorized purchases. This is something you should be doing anyway, of course, but now is as good a time as any to remind you to comb through your statements and track your spending.
