The company also says some social security numbers were stolen. Eyewitness News reached out to a cyber security expert on how we can be more vigilant with our private information.

“You want to make sure you’re on top of it. Ideally, you’re finding out before they notify you so you can take the necessary steps,” Professor Rob D’Ovidio, of Drexel University, said. “To do that, you’ve gotta monitor your credit, you’ve gotta monitor your statements to make sure there are no suspicious activity on your accounts and you’ve gotta be mindful of who you’re giving your information to.”

D’Ovidio says you should also make sure your phones and computers are up to date with security features as well.
