There’s a new leader on the U.S. Department of Health & Human Services’ Wall of Shame.
A hacking group known as “APT 18” is suspected of stealing names, Social Security numbers, addresses, birthdays and telephone numbers from 4.5 million patients of Community Health Systems, a network of 206 hospitals across 29 states (see map at right). Credit card numbers and medical records were not accessed.
It’s the largest attack involving patient information since the HHS started tracking HIPAA breaches in 2009, passing a Montana Department of Public Health breach that affected roughly 1 million people.
Patients who were referred or received services from doctors affiliated with Community Health Systems in the last five years were affected, the company reported in a regulatory filing on Monday. The sophisticated malware attacks occurred in April and June.
According to numerous news reports, security experts said the hacker group may have links to the Chinese government. Charles Carmakal, managing director of the Mandiant forensics unit, hired by the hospital group to consult on the hack, told Reuters that “APT 18” typically targets companies in the aerospace and defense, construction and engineering, technology, financial services and healthcare industry.
In an Online Tech webinar titled “Why is it So Hard to Secure a Company,” security expert Adam Goslin discussed how the past decade has seen “a continuous and steady increase in attempts by specifically the Chinese attempting to gain intellectual property.”
According to a CNN report, Mandiant and federal investigators told the hospital network that the hacking group has previously conducted corporate espionage to target information about medical devices. This time, however, the bounty was patient data.
Community Health Systems stated in a release: “Our organization believes the intruder was a foreign-based group out of China that was likely looking for intellectual property. The intruder used highly sophisticated methods to bypass security systems. The intruder has been eradicated and applications have been deployed to protect against future attacks.”
In his aforementioned webinar, Goslin, the CEO of Total Compliance Tracking, detailed examples of the value of intellectual property theft:
One of the stories that the FBI was bringing up was the Chinese were trying to get into a manufacturing facility to get a sample of a rinse solution for some type of a glass manufacture. It was a coating for glass and they couldn’t figure how they were doing it. So, the Chinese were trying to get a hold this of this rinse solution in the manufacturing setting. …
There was a story of an organization that had spent some number of years developing a patent. They were just about to file it and found that they have gotten hacked by the Chinese. The Chinese filed for the patent. Because the organization’s entire business revolved around this work, they literally had to pay royalties to the Chinese just to use the patent that they developed themselves that got hacked out from under them.
The value of personal information is clear: Hackers can sell the information to those looking to steal identities. And hospital networks are becoming a hotbed for finding that information.
Michael “Mac” McMillan, CEO of security consulting firm CynergisTek, told Modern Healthcare that hospitals are “going to become a bigger and bigger target as the hacking community figures out it’s easier to hack a hospital than it is to hack a bank and you get the same information. I’m not sure healthcare is listening yet.”
McMillan told the website there has been a spike in hacking activity directed at hospitals this year:
“I know at least a half a dozen or so hacks against hospitals we work with where the data wasn’t transferred, but it still caused a lot of disruption,” McMillan said. “But it wasn’t a HIPAA issue, so it didn’t get reported.”
