During a House committee hearing on Wednesday, Roberta Stempfley — acting assistant secretary of the Department of Homeland Security’s Office of Cybersecurity and Communications — said her agency was aware of “about 16” reports of cybersecurity threats related to the HealthCare.gov website.
Testifying before the House of Representatives Homeland Security Committee, Stempfley also said officials were aware of an unsuccessful attempt by hackers to organize a “denial of service” attack to overwhelm and take down the website.
Stempfley’s testimony marked the first time that the Obama administration publicly discussed cybersecurity threats to the website at the heart of the law known as Obamacare.
