University of California (UCLA) Health, which runs four hospitals on the university's campuses, has become the latest victim of cyber-attack. Hackers may have accessed information on as many as 4.5 million patients.
The invasion raises questions about the ability of hospitals, health insurers and other medical providers to keep their electronic medical records and other sensitive information protected and safe.
UCLA had not encrypted the patient data, drawing much criticism from security experts and patient advocates, especially at a time when cyber-criminals are targeting so many big timers in healthcare, retail and government.
UCLA said that it's working with the FBI and hired computer forensic experts to further secure its network.
There is no evidence yet that patient data were taken, but the possibility cannot be ruled out while the investigation continues.
