The breach occurred late last year and the company acknowledged on its website last week that there was “a potential leak of certain data in April 2024 and summer 2024.”

Data going back at least three decades is said to be affected by the data breach – and the fact that social security numbers are also included has caused concern among many people. Want to know if you’re affected? Here’s how to find out.

How can I find out if my Social Security number was affected by the breach?

Pentester, a cybersecurity company, has developed a tool that can help you determine if your information was part of the data breach. Navigate to npd.pentester.com in a web browser and enter your first and last name and year of birth. You will see a list of hacked accounts, including the last four digits of the leaked social security numbers.

What should I do if my Social Security number was affected by the breach?

NPD advises potentially affected individuals to closely monitor their bank accounts. Most Americans don’t keep a close eye on their checking and savings accounts or check every item on their credit card statements – and hackers rely on that.

It’s also a good idea to set up credit monitoring to make sure no one is using your personal information. Also, contact one of the three U.S. credit bureaus (Equifax, Experian and TransUnion) to set up a fraud alert on your account. This tells creditors to contact you before opening new accounts or making changes to your existing accounts. (Once this is set up at one agency, it applies to the others as well. It stays active for one year and can be renewed.)

If you are particularly concerned about identity theft, there is another option: a credit freeze, which prevents the issuance of new credit without your direct consent.

“Your best protection against someone opening new credit accounts in your name is a security freeze (also called a credit freeze), not the often-offered, underperforming credit monitoring,” notes the U.S. Public Interest Research Group.
