In the end of October 2021, the Newfoundland and Labrador healthcare system was hit by the worst cyberattack in Canadian history. It was suspected that Conti, a ransomware attack gang, stole the personal information of their patients and healthcare employees, causing medical service disruptions and delays for weeks. The same gang of cybercriminals have targeted approximately 290 healthcare organizations in the U.S since mid-May 2021.
These incidents demonstrate that no healthcare provider is too small or too big to be targeted by a cyberattack. However, threat actors are targeting certain types of healthcare providers over others with health or medical clinics and healthcare industry services being impacted significantly more than hospitals, pharmaceutical, and hospice or elderly care institutions.
Cybercriminals target healthcare providers because it’s lucrative. In fact, as of May 25, 2021, the Health Sector Cybersecurity Coordination Center (HC3) tracked 82 ransomware incidents targeting the healthcare sector globally, 48 of these ransomware attack incidents were reported in the United States alone.
What makes healthcare organizations an attractive target for cyberattacks?
For cybercriminals, stealing patient data is the big win–one record can fetch up to $250 on the Dark Web, approximately 50x more than the next best stolen data, credit and debit card numbers. The ransom demand is also higher at $4.5M on average because the cyberattackers know that patient lives are at stake.
In addition to the lure of money, we’ve identified four major vulnerabilities that attract cybercriminals:
- Lack of strong cybersecurity posture: The healthcare industry has made insufficient investment in the technologies needed to mitigate a data breach. Their poor cybersecurity posture makes them susceptible to the most basic, opportunistic cyberattacks.
- Poor incident response and remediation: Without the support of 24/7 data backups and a team of Incident Response (IR) experts that can respond and remediate cyber threats immediately after detection and containment, healthcare institutions are likely to pay the extortion or ransomware demands to avoid massive operational disruption.
- An ever-expanding attack surface: Healthcare’s growing reliance on cloud and hybrid data management solutions, cloud apps, internet connected medical devices, and even point-of sale terminals has opened new entry points for cyberattacks.
- Lack of skilled cybersecurity practitioners: Many healthcare organizations don’t invest in hiring enough skilled cybersecurity practitioners, which can put them at a disadvantage in defending against the today’s most sophisticated cyber threats.
These factors, paired with outdated systems, applications, and technologies, make for a very difficult cybersecurity challenge that your security team must be well-equipped to solve.
Ransomware attack groups like Conti and Avaddon frequently launch cyberattacks on healthcare organizations with little regard for the impact cyberattacks can have on patient lives. In fact, these cyber threat actors are adept at bypassing traditional defenses like firewalls and antivirus systems, often remaining undetected within the environment for days or weeks before ‘detonating’ a ransomware attack or disabling services.
Additionally, in recent years, healthcare organizations have even fallen prey to a new trend of double-extortion and triple-extortion ransomware attacks. In a double-extortion, the cyberattackers exfiltrate data and threaten to sell it unless they’re paid a higher ransom. In a triple-extortion, the cyberattackers threaten to launch a distributed denial-of-service (DDoS) attack that could further disrupt healthcare services.
Shielding your healthcare practice from cyberattacks
The first step in managing cyber risk in today’s threat environment is to adopt the mindset that cybersecurity isn’t an IT problem to solve—it’s a business (and patient outcome) risk to manage.
It’s important to recognize the growing risk of data breaches and cyberattacks to take the necessary precautions to avoid them. Adopting a risk-based approach to cybersecurity includes:
- Phishing and Security Awareness Training to level-up employees’ understanding of the most common tactics, techniques, and procedures that cyberattackers use
- A comprehensive vulnerability management program that includes three elements: awareness of the cyber threat landscape (e.g., from advisories, notifications, cyber news, etc.); vulnerability scanning to understand your cyber threat surface, including ‘discovering’ systems that are inadvertently exposed; and disciplined patch management
- Managed Detection and Response (MDR) to identify when a cyber threat actor has broken through traditional defenses and respond rapidly to contain it before they can achieve their objectives
- Having a Digital Forensics and Incident Response provider on retainer to provide post-incident expertise
