content: As far as I know, anyone who had an Equifax credit score. So almost anyone who ever had a house load, car loan, or credit card. If you pay any type of utility (or rent) where you needed a credit check first, chances are when you pay those bills they are reported to Equifax. So if you fall into any of those categories, your data was probably part of the leak. There are two other another credit score services (TransUnion and Experian) and occasionally some of the things I mentioned are only reported to one service (in which case I believe it is possible to have a credit score without having an Equifax "account") but that's very rare. Now, whether your data was/is/will be used for identity theft at any point in the future (1,5,10,50+ years in the future), who knows. "But don't worry! As compensation here's a limited time trial of our subscription service that will monitor your credit!"
