Data Breach

Mason LLP actively monitors the latest cyberattacks affecting consumers, particularly those compromising financial or highly sensitive information. The personal information maintained by your doctor, hospital insurance company, and other companies you deal with is increasingly at risk of exposure due to ransomware attacks and data thefts. Mason LLP is currently litigating cases across the country involving violations of privacy law, violations, data breaches, and ransomware attacks.

If you received a data breach notification letter, you should take certain steps to safeguard your identity. We recommend the following:

  • Get your free credit report from, and check for any accounts or charges you don’t recognize.
  • Subscribe to credit and identity monitoring services. Check the monitoring application regularly to see if your data has been compromised or if your data is being used for fraudulent purposes;
  • Consider placing a free credit freeze.  A credit freeze makes it harder for someone to open an account in your name.
  • Try to file your taxes early, before a scammer can. Tax identity theft happens when someone uses your Social Security number to get a tax refund or a job. Respond right away to letters from the IRS.
  • Don’t believe anyone who calls and says you’ll be arrested unless you pay for taxes or debt — even if they have part or all of your Social Security number, or they say they’re from the IRS.
  • Change your online passwords and security questions;
  • Regularly review your credit card and bank account statements for signs of suspicious activity;
  • Monitor your credit report for any unexpected changes that may be a sign of identity theft;
  • Contact one of the major credit bureaus to request they add a fraud alert to your profile; and
  • Immediately notify your banks and credit card companies if you identify any suspicious activity

What Else Should You Do?

Data breach victims may be able to seek compensation through a class action.  Class actions are frequently filed against companies that are breached. While these cases sometimes go to trial, most data breach class action settle and provide a variety of benefits to class members.  These benefits may include additional years of credit and identity monitoring, compensation for time spent responding to the breach, reimbursement for any losses from fraud related to the breach, or nominal damages.  If you want to learn more about data breach class actions and how you can participate in one against FCHC, you should contact a data breach attorney at Mason LLP as soon as possible.
