Major Data Compromise at UCLA Health System

Hackers forced entry into parts of the hospital’s network that contain medical and personal information.

There is no evidence yet that data was copied, but the possibility cannot be ruled out, UCLA said.

“UCLA Health has been investigating suspicious activity on its network since October, but the intrusion wasn't confirmed until May,” the LA Times reports.

According to CNN, evidence indicates the hackers crawled into computers in September 2014. In October 2014, university network alarms detected suspicious activity.

"At that time, it did not appear that the attackers had gained access to the parts of the network that contain personal and medical information," UCLA Health said in a statement.

It was not until May 5, 2015 that UCLA discovered the bad guys actually accessed computers with sensitive records.

The incident could affect anyone who has visited or worked at the university's medical center, UCLA Health, which includes four hospitals and 150 offices across Southern California, CNN reports.

Investigators suspect the attackers were part of a “highly sophisticated offshore group,” according to the LA Times.

Hackers could see customers’ names, addresses, Social Security numbers, health insurance IDs and diagnosis and treatment records.

Notifications will go out to affected patients during the next few weeks.
