For example, one of the major distributors of dental supplies, Henry Schein Inc., has fallen victim to a significant data breach affecting its core systems, including distribution and ecommerce. The company, with sales reaching US$12.6 billion in 2022, recently regained online functionality after the cyberattack on October 14.
The incident led to a delay in filing the third-quarter earnings report, and Henry Schein anticipates filing an insurance claim in 2024 with a $60 million after-tax claim limit. Despite challenges, the company expressed gratitude for customer support and acknowledged the prevalence of cyber issues in the healthcare sector.
Moreover, the proliferation of medical devices, such as x-rays, insulin pumps, and defibrillators, introduces a new frontier for attackers.
While these devices serve critical functions in modern healthcare, security often takes a back seat in their design. Hackers recognize them as vulnerable entry points, exploiting them to compromise servers holding valuable patient information.
The consequences can be dire, ranging from unauthorized access to other network devices to the installation of costly ransomware, hindering healthcare organizations’ ability to deliver essential, life-saving treatments.
The healthcare industry’s reliance on remote access further amplifies its susceptibility to cyber threats. Collaborative working, a cornerstone of effective patient care, necessitates accessing information from diverse locations and devices. Unfortunately, this flexibility opens up opportunities for attacks, especially when staff members, under the pressures of their demanding schedules, may not adhere to cybersecurity best practices.
This lack of awareness and the absence of comprehensive cybersecurity education for healthcare professionals create an environment where even basic security measures are overlooked.
Compounding the issue is the resistance to adopting new technologies among healthcare staff, who are already burdened with tight deadlines and long working hours. This reluctance to disrupt familiar workflows leaves vulnerabilities unaddressed, making it easier for hackers to exploit the system.
