Health Net healthcare data breach affects 1.5 million customers
Health Net Inc. announced Wednesday that it is investigating a healthcare data security breach that resulted in the loss of patient data, affecting 1.5 million customers.
The Woodland Hills, Calif.-based managed healthcare provider said the lost files, a mixture of medical data, Social Security numbers and other personally identifiable information, were collected over the past seven years and contained on a portable external hard drive, which was lost six months ago. The company said the healthcare data was not encrypted, but was formatted as images and required a specific software application to be viewed. The hard drive contained data on 446,000 Connecticut patients.
The company reported the breach Wednesday to State Attorneys Generals offices in Arizona, Connecticut, New Jersey and New York. Health Net said it was beginning the data security breach notification process of sending out letters to its customers. The company said it expects to send notification letters the week of Nov. 30.
Connecticut Attorney General Richard Blumenthal said he was investigating the matter and why it took Health Net six months to report the healthcare breach.
“My investigation will seek to establish what happened and why the company kept its customers and the state in the dark for so long,” Blumenthal said in a statement. “The company’s failure to safeguard such sensitive information and inform consumers of its loss — leaving them naked to identity theft — may have violated state and federal laws.”
