What You Should Do Now
- Activate free monitoring: Enroll in the Epiq Privacy Solutions services provided in the notice letter.

Data-breach litigation often proceeds as a class action, allowing affected individuals to band together. An experienced attorney can confirm eligibility and guide you through next steps.
