Why This Breach Matters

What Cornerstone First Mortgage Held About You

Financial institutions and insurance companies are high-value targets because the data they hold can be used to open fraudulent accounts, drain existing ones, or file fake tax returns. A breach at a financial services company may expose your account numbers, routing numbers, Social Security number, and date of birth — everything a fraudster needs.

Massachusetts residents are protected by M.G.L. c. 93H, which gives you the right to pursue legal remedies when a company fails to adequately protect your data.
