Quest Diagnostics Data Breach Lawsuits

Quest Diagnostics, a medical laboratory testing company, disclosed that an unauthorized party gained access to its Quantum Lab Services Manager (LSM) system. This breach involved the exposure of certain patient records, which included protected health information and personally identifiable information. The company initiated cybersecurity incident response procedures and notified federal law enforcement authorities upon discovering the unauthorized access.

The plaintiffs in the filed lawsuits allege that the compromised data is now accessible on the dark web, with accusations suggesting an employee may have opened a file containing a ransomware virus. These claims are brought in the context of data security failures, and the lawsuits are filed in federal court in New Jersey.

As of October 23, multiple class action lawsuits are active in New Jersey federal court. Affected individuals are encouraged to monitor developments, as the company is in the process of identifying impacted patients and providers and making required notifications.
