Hackers accessed computers with sensitive records of 4.5 million people


In July 2015, the healthcare company disclosed that an attacker had accessed parts of their network that contained the personal information of 4.5 million individuals. At that time it was the fourth-biggest healthcare data breach of all time. There were "indications" that led the company to believe that the attacker may have initiated the network access as early as September 2014.

The potentially exposed information included names, addresses, dates of birth, social security numbers, medical record numbers and some medical information (such as medical condition, medications, procedures and test results).
