The healthcare industry has recently come under heavy fire as a target of cybercrime. Ransomware attacks on hospitals in California, Indiana, Kentucky, and Maryland, forced some officials there to make quick decisions in order to get their systems back up and running to avoid disruption of patient care.
The research team at Duo Security today released a report on the current state of healthcare endpoint security that compared the company's healthcare industry customers’ device cybersecurity to that of other industries. According to the findings, the healthcare sector has yet to come up to speed on information security.
Here’s a look at the key reasons cybercriminals are targeting healthcare institutions.
1. Healthcare is historically not very secure.
In 2009, Congress passed the Health Information Technology for Economic and Clinical Health (HITECH) Act that required hospitals to switch from paper to electronic health records (EHRs). With this came a flood of new health information technology and concerns that some of these vendors were bypassing security measures in order to get their products to market quickly, leaving the already newly digital healthcare institutions open and susceptible to cyberattacks.
Healthcare institutions are still holding on to legacy pieces of software, which makes them a much easier target, says Mike Hanley, director of Duo Labs. He adds that educating users about when it’s time to update software and systems or making them aware of phishing emails can be difficult.
2. It’s life or death.
Because lives are at stake, healthcare professionals and their patients often can’t afford to have systems down or wait for an incident response team to come in and clean up the mess. This makes them prime targets for ransomware attacks. They often pay the ransom in order to get their systems back up and running, Hanley says.
It’s front page news if a hospital in a major metropolitan area goes dark due to a cyberattack, he says, which is bad for the hospital’s reputation and as well as patient well-being – you can’t have people avoiding the hospital for fear of having their patient records stolen or compromised.
3. The data is lucrative.
In addition to being ripe for the ransomware-picking due to the need for fast recovery times, hospitals also house a lot of private data. When cybercriminals steal a patient’s healthcare records, they’re often able to acquire multiple pieces of information: social security number, medical history, insurance provider, the patient's medications, and so on. “There’s a larger concentration of sensitive information [that can be resold],” Hanley says.
4. An application-heavy environment provides a broad attack landscape.
According to the Duo Labs report, Duo Security healthcare customers are logging into twice as many applications as the average user in other industries. “This in itself is not a security risk or problem, but more diverse systems ... [may] require them to use old systems,” Hanley says, which could put them at risk of attack.
5. They have an affinity for Windows and out-of-date browsing.
The healthcare industry is still using out-of-date, legacy systems. The report found that 82% of healthcare organizations are using Windows, and 76% are running on Windows 7.
They’re also partial to Internet Explorer (IE) 11, and 22% of Duo Security healthcare customers browse on unsupported versions of IE.
Hospital employees wash their hands to avoid getting the common cold and they need to employ the same basic measures to keep their information security systems healthy, Hanley says. “[It’s about] getting back to the basics, user education, security hygiene.”
