What we know

While the specific types of information involved were not detailed in the public filing, any compromise of personal data can create risks for affected individuals.

Consider placing a fraud alert on your credit files with the three major credit bureaus. For more robust protection, you might also explore placing a credit freeze, which restricts access to your credit report, making it harder for identity thieves to open new lines of credit. These steps can help mitigate the risks associated with the exposure of your personal information.

Being impacted by a data breach can be unsettling, and understanding your options is important. If you are concerned about your rights or the steps you should take, speaking with an attorney can provide clarity.
