LabCorp, a healthcare diagnostics company, has shut down its systems after a suspected network breach, which could have put millions of health records at risk.
In a report to the United States Securities and Exchange Commission, the company announced that during the weekend of July 14 2018, it had detected suspicious activity on its IT network and immediately took specific systems offline. The company said that the suspicious activity has been detected only on LabCorp Diagnostics systems, and that "there was no indication that it affected systems used by Covance Drug Development."
