If you find out that your data was compromised, you need to freeze your credit, first and foremost. Once you do that, anyone who tries to use your credit needs the special PIN we mentioned above -- just be sure you receive the randomized version. After that, it's important that you enroll in a credit monitoring service. Equifax is now offering the data breach victims a free year of TrustID. This includes "3-Bureau credit monitoring of Equifax, Experian and TransUnion credit reports; copies of Equifax credit reports; the ability to lock and unlock Equifax credit reports; identity theft insurance; and Internet scanning for Social Security numbers."
