Ultrasound Machine Diagnosed with Major Security Gaps

Check Point researchers investigate security risks and point to implications for medical IoT devices.

RSA CONFERENCE 2019 – San Francisco – Vulnerabilities in connected medical devices could have massive implications for patients and the healthcare industry as a whole.

The Internet of Medical Things (IoMT) is poised to broaden the attack surface for healthcare organizations, according to Check Point experts. Eighty-seven percent of healthcare institutions are expected to use IoT technologies by the end of 2019, with nearly 650 million IoMT devices in use by 2020, states a new Check Point study. The study underscores the danger of what could happen if these devices are poorly secured.

IoT devices collect vast stores of data and are commonly built on outdated software and legacy operating systems. This makes them a simple gateway for cybercriminals, who could break in and move laterally across the target network.

Consider ultrasound technology. Researchers explain how "huge advancements" have been made to provide detailed health data to doctors and patients. Unfortunately, they report, this innovation hasn't made its way to the security of IT environments where ultrasound machines sit. To prove this point, they went "under the hood" of a real ultrasound device.

What they found was a tool running on Windows 2000. Like many IoMT devices, this no longer receives updates or patches, and leaves both the machine and its data exposed to intruders. It wasn't hard to exploit vulnerabilities and access its database of ultrasound images, they explain.

An attacker with this access could launch a ransomware campaign on the hospital system or swap patients' images. "Think how much chaos that can do in the hospital," said Oded Vanunu, head of product vulnerability research at Check Point, in an interview with Dark Reading here at the RSA Conference.

Cybercriminals may use health records to get pricey medical services and prescription medications; they may also gain access to government health benefits. Or they could sell it: The Ponemon Institute found healthcare breaches are most expensive, at $408 per record.

Healthcare organizations often don't have the budget for strong IT and security, Vanunu explained. "Hospitals are flat networks – from our perspective ... we think cybercrime will start to move to the weakest networks." It's happening already, he noted.

IoMT devices are in mass production, Vanunu continued, but nothing is being done to secure them. Because the device Check Point analyzed was running Windows 2000, exploiting it was simple. "We didn't use any sophisticated tools," Vanunu said. "No zero-day, no reverse-engineering vulnerability. Any beginner can exploit it."

Re: On healthcare in general
Thanks - worst job ever.  30 computers walked out of a locked room - 30.  Just like that.  Computer in Pastor's office stolen.  Computer in corp cafeteria stolen- cable cut too.  11,000 endpoints - no firewall.  We would image and porn back in a week.  Doctor lounge systems loaded with porn.  Education systems for chilldren loaded with porn.  (Outsourced suppor to First Consulting group, later bought by Computer Sciences Corp.)

There was one more slice of hell - hard-coded IPs and subnets.  But nobody knew where one subnet began in a room and the next kicked in.  Delihtful planning.

Re: On healthcare in general
Wow, thats disheartening. Working at a hospital I have seen the horrors that COW's can provide as well. I still think your experience would have to top the list I think.

On healthcare in general
Ages ago i had a positon with a MAJOR NY Hospital for support.  One uptown hospital had COWS ( computers on wheels) that staff could wheel into a patient's room.  They are quite common.  Now ths place was a horror show in many ways but one great one was that COWS wireless received IP from the college across the street.  True.  Out the door went the patient management cloud program.  Out went patient data and history, medication data, care data....... and that was one, just one, flaw.  Not surprised at all by this essay.
