Healthcare is in Cybercriminals’ Crosshairs

August 6, 2019 — by Mark Taylor0

healthcare-960x640.jpg

The healthcare industry is a prime target of hackers. According to Radware’s 2018-2019 Global Application and Network Security Report, healthcare was the second-most attacked industry after the government sector in 2018. In fact, about 39 percent of healthcare organizations were hit daily or weekly by hackers and only 6 percent said they’d never experienced a cyber attack.

Increased digitization in healthcare is a contributor to the industry’s enlarged attack surface. And it’s accelerated by a number of factors: the broad adoption of Electronic Health Records Systems (EHRS), integration of IoT technology in medical devices (software-based medical equipment like MRIs, EKGs, infusion pumps), and a migration to cloud services.

Case in point: 96% of non-federal acute care hospitals have an EHRS. This is up from 8% in 2008.  

Accenture estimates that the loss of data and related failures will cost healthcare companies nearly $6 trillion in damages in 2020, compared to $3 trillion in 2017. Cyber crime can have a devastating financial impact on the healthcare sector in the next four to five years.

The Vulnerabilities

According to the aforementioned Radware report, healthcare organizations saw a significant increase in malware or bot attacks, with socially engineered threats and DDoS steadily growing, as well. While overall ransomware attacks have decreased, hackers continue to hit the healthcare industry the hardest with these attacks. And they will continue to refine ransomware attacks and likely hijack IoT devices to hold tech hostage.

Indeed, the increasing use of medical IoT devices makes healthcare organizations more vulnerable to DDoS attacks; attackers use infected IoT devices in botnets to launch coordinated attacks.

Additionally, cryptomining is on the rise, with 44 percent of organizations experiencing a cryptomining or ransomware attack. Another 14 percent experienced both. What’s worse is that these health providers don’t feel prepared for these attacks. The report found healthcare “is still intimidated by ransomware.”

The Office of Civil Rights (OCR) has warned about the dangers of DDoS attacks on healthcare organizations; in one incident, a DDoS attack overloaded a hospital network and computers, disrupting operations and causing hundreds of thousands of dollars in losses and damages.

Why Healthcare?

The healthcare industry is targeted for a variety of reasons. For one thing, money. By 2026, healthcare spending will consume 20% of the GDP, making the industry an attractive financial target for cyber criminals. And per Radware’s report, the value of medical records on the darknet is higher than that of passwords and credit cards.

And as my colleague Daniel Smith previously wrote, “not only are criminals exfiltrating patient data and selling it for a profit, but others have opted to encrypt medical records with ransomware or hold the data hostage until their extortion demand is met. Often hospitals are quick to pay an extortionist because backups are non-existent, or it may take too long to restore services.”

Regardless of motivation, one thing is certain: Ransomware and DDoS attacks pose a dangerous threat to patients and those dealing with health issues. Many ailments are increasingly treated with cloud-based monitoring services, IoT-embedded devices and self or automated administration of prescription medicines. Cyber attacks could establish a foothold in the delivery of health services and put people’s lives and well-being at risk.

Recommendations

Securing digital assets can no longer be delegated solely to the IT department. Security planning needs to be infused into new product and service offerings, security, development plans and new business initiatives–not just for enterprises, but for hospitals and healthcare providers alike.

To prevent or mitigate DDoS attacks, US-Computer Emergency Readiness Team (US-CERT) recommends that organizations consider the following measures:

  • Continuously monitoring and scanning for vulnerable and comprised IoT devices on their networks and following proper remediation actions
  • Creating and implementing password management policies and procedures for devices and their users; ensuring all default passwords are changed to strong passwords
  • Installing and maintaining anti-virus software and security patches; updating IoT devices with security patches as soon as patches become available is critical.
  • Installing a firewall and configuring it to restrict traffic coming into and leaving the network and IT systems
  • Segmenting networks where appropriate and applying security controls for access to network segments
  • Disabling universal plug and play on routers unless absolutely necessary

2018 In Review: Healthcare Under Attack

December 12, 2018 — by Daniel Smith0

Healthcare-Under-Attack-960x568.jpg

Radware’s ERT and Threat Research Center monitored an immense number of events over the last year, giving us a chance to review and analyze attack patterns to gain further insight into today’s trends and changes in the attack landscape. Here are some insights into what we have observed over the last year.

Healthcare Under Attack

Over the last decade there has been a dramatic digital transformation within healthcare; more facilities are relying on electronic forms and online processes to help improve and streamline the patient experience. As a result, the medical industry has new responsibilities and priorities to ensure client data is kept secure and available–which unfortunately aren’t always kept up with.

This year, the healthcare industry dominated news with an ever-growing list of breaches and attacks. Aetna, CarePlus, Partners Healthcare, BJC Healthcare, St. Peter’s Surgery and Endoscopy Center, ATI Physical Therapy, Inogen, UnityPoint Health, Nuance Communication, LifeBridge Health, Aultman Health Foundation, Med Associates and more recently Nashville Metro Public Health, UMC Physicians, and LabCorp Diagnostics have all disclosed or settled major breaches.

Generally speaking, the risk of falling prey to data breaches is high, due to password sharing, outdated and unpatched software, or exposed and vulnerable servers. When you look at medical facilities in particular, other risks begin to appear, like those surrounding the number of hospital employees who have full or partial access to your health records during your stay there. The possibilities for a malicious insider or abuse of access is also very high, as is the risk of third party breaches. For example, it was recently disclosed that NHS patient records may have been exposed when passwords were stolen from Embrace Learning, a training business used by healthcare workers to learn about data protection.

Profiting From Medical Data

These recent cyber-attacks targeting the healthcare industry underscore the growing threat to hospitals, medical institutions and insurance companies around the world. So, what’s driving the trend? Profit. Personal data, specifically healthcare records, are in demand and quite valuable on today’s black market, often fetching more money per record than your financial records, and are a crucial part of today’s Fullz packages sold by cyber criminals.

Not only are criminals exfiltrating patient data and selling it for a profit, but others have opted to encrypt medical records with ransomware or hold the data hostage until their extortion demand is met. Often hospitals are quick to pay an extortionist because backups are non-existent, or it may take too long to restore services. Because of this, cyber-criminals have a focus on this industry.

[You may also like: How Secure is Your Medical Data?]

Most of the attacks targeting the medical industry are ransomware attacks, often delivered via phishing campaigns. There have also been cases where ransomware and malware have been delivered via drive-by downloads and comprised third party vendors. We have also seen criminals use SQL injections to steal data from medical applications as well as flooding those networks with DDoS attacks. More recently, we have seen large scale scanning and exploitation of internet connected devices for the purpose of crypto mining, some of which have been located inside medical networks. In addition to causing outages and encrypting data, these attacks have resulted in canceling elective cases, diverting incoming patients and rescheduling surgeries.

For-profit hackers will target and launch a number of different attacks against medical networks designed to obtain and steal your personal information from vulnerable or exposed databases. They are looking for a complete or partial set of information such as name, date of birth, Social Security numbers, diagnosis or treatment information, Medicare or Medicaid identification number, medical record number, billing/claims information, health insurance information, disability code, birth or marriage certificate information, Employer Identification Number, driver’s license numbers, passport information, banking or financial account numbers, and usernames and passwords so they can resell that information for a profit.

Sometimes the data obtained by the criminal is incomplete, but that data can be leveraged as a stepping stone to gather additional information. Criminals can use partial information to create a spear-phishing kit designed to gain your trust by citing a piece of personal information as bait. And they’ll move very quickly once they gain access to PHI or payment information. Criminals will normally sell the information obtained, even if incomplete, in bulk or in packages on private forums to other criminals who have the ability to complete the Fullz package or quickly cash the accounts out. Stolen data will also find its way to public auctions and marketplaces on the dark net, where sellers try to get the highest price possible for data or gain attention and notoriety for the hack.

Don’t let healthcare data slip through the cracks; be prepared.

In February of 2017, Memorial Healthcare System settled their HIPAA violation fines for $5.5 Million USD. During an investigation, it was discovered that over 100,000 patient records had been impermissibly accessed. Allegedly, an ex-employee retained access to personal identifying information and sold data records to people who filed fraudulent tax returns using the data. Federal criminal charges were filed against the ex-employee.
