Our Data Breach Experience

Holding Companies Accountable for Data Breaches

Data breaches can compromise peoples’ personal information, risking financial, reputational, or other harm to those affected. When a data breach results from either negligent security or intentional or reckless behavior, the company, organization, or governmental body storing it may be held accountable.

Gibbs Mura’s attorneys have filed privacy violations lawsuits on behalf of people around the United States who have had their private information exposed as the result of a data breach. We work to compensate those affected while holding companies accountable for inadequate security measures and to ensure corporate privacy policies improve.

Data Breach Class Action Lawsuits

At Gibbs Mura, our attorneys have represented victims of privacy violations in a number of privacy lawsuits. Several recent examples include:

Health Net & IBM Medical Records Data Breach Lawsuit

In March 2011, Health Net notified hundreds of thousands of patients that their private information had been compromised through a data breach, potentially exposing patients’ names, addresses, medical information, Social Security numbers, and other financial information. Gibbs Mura filed a class action lawsuit alleging that Health Net and its server driver company, IBM, violated patients’ privacy rights and other consumer protection laws.

Certegy Financial (now Fidelity National Information Services) Data Breach Class Action

Gibbs Mura represented thousands of consumers in a class action lawsuit against Certegy Check Services after their financial and personal data was sold to third-parties by a Certegy employee. The case alleged that Certegy violated customer’s privacy rights and financial privacy laws when it failed to implement adequate security measures to protect customers’ personal information.

Adobe Data Breach Class Action Lawsuit

In November 2013, Gibbs Mura filed a class action lawsuit against Adobe for its failure to use reasonable security practices that resulted in a data breach affecting approximately 38 million Adobe users.  The lawsuit alleges that Adobe failed to use industry best practices for security, contrary to Adobe’s Privacy Policy and representations regarding the company’s security practices.
