Quest says cyber incident may have exposed patient records

Quest Diagnostics said unauthorized access to its Quanum Lab Services Manager platform may have exposed certain patient records, prompting the company to restrict access while it investigates. The company said the incident has not materially disrupted its business or its ability to serve patients. In a filing Thursday with the U.S. Securities and Exchange Commission, Quest said it learned Wednesday of unauthorized access to Quanum LSM. Some healthcare providers use the platform to order laboratory tests and receive or review results. Quest believes an unauthorized party accessed certain patient records, but the investigation has not established which records were involved or how many people may be affected. Quest said it notified federal law enforcement and engaged outside cybersecurity experts to assist with its investigation and response. It is working to identify potentially affected patients and healthcare providers and said it will provide notifications as required by applicable law. The company temporarily restricted access to its Quanum LSM platform. It also paused access to Essential Insights and LabHQ as a precaution, saying no data was accessed on those systems....
