Mason Law Office

Mason Law Office, also known as MLO, is a legal services provider operating within the United States of America. The firm handles client cases, which involve managing sensitive personal information and privileged legal documentation as part of their core legal representation activities. Their work necessitates the processing and storage of confidential client data related to legal matters. The firm utilizes online case management systems, such as mycase.com, to support its legal practice operations and client service delivery.

In May 2018, Mason Law Office experienced a significant cybersecurity incident involving unauthorized access to their mycase.com system. This breach potentially exposed highly sensitive client information, including names, Social Security numbers, driver's license details, and contact information. Furthermore, privileged legal documents such as case notes, financial statements, and attorney communications were also potentially compromised during the incident. Attackers deleted case data and altered administrative settings within the platform. The firm publicly stated that it routinely redacted identifiable financial information before uploading documents to the compromised system and confirmed that payment data was not stored within the mycase.com platform at the time of the breach. This incident highlighted the firm's reliance on third-party systems for managing critical client data and legal workflows.
