U.S. Sen. Mark Warner (D-VA) wrote today to the CEO of Quest Diagnostics, asking for information on the company’s supply chain management and cybersecurity practices after the company reported on Monday that approximately 11.9 million Quest patients may have been compromised as a result of a breach to a system used by one of Quest’s contractors.
“While I am heartened to learn that no evidence currently suggests Quest Diagnostic’s systems were breached, I am concerned about your supply chain management, and your third party selection and monitoring process. According to a recent report, 20 percent of data breaches in the health care sector last year were traced to third-party vendors, and an estimated 56 percent of provider organizations have experienced a third-party breach,” Sen. Warner wrote in his letter to Stephen Rusckowski, Chairman, President and CEO of Quest Diagnostics.
Earlier this year, Sen. Warner, a member of the Senate Finance Committee and co-chair of the Senate Cybersecurity Caucus, sent letters to multiple health care associations and government agencies including the Food and Drug Administration, Department of Health and Human Services, Centers for Medicare and Medicaid Services, and National Institute of Standards and Technology, seeking more information about steps being taken to reduce cyber vulnerabilities in the health care industry, which has become a growing target for cyberattackers. In the letters, Sen. Warner pointed to apparent gaps in oversight, expressed concern about the impact of cyber-attacks on the health care sector, and conveyed his desire to work alongside stakeholders to develop strategies that strengthen information security.
In today’s letter to Quest, Sen. Warner asked the company to provide additional information regarding the breach and the company’s processes for selecting and monitoring sub-contractors and vendors.
