Cybercriminals Have an Unhealthy Appetite for Medical Data

 

Cybercriminals just love targeting healthcare organizations and have been doing it quite often for many years. As can be seen on the table below, during the past couple of months cybercriminals have been working hard on these types of targets. where they hit with ransomware attacks or breach to exfiltrate medical records which they can monetize. These medical records are a treasure trove of information that is easy to sell on the dark web. In contrast to e.g., financial institutions, healthcare organizations have a hard time allocating sufficient resources to defend their network perimeter to keep cybercriminals at bay, as is illustrated in the recent attacks outlined below

Healthcare data is hard to protect, especially due to the rise in the use of healthcare technology and electronic devices, healthcare data records are spread all through (and exchanged between) healthcare organization.  As we have seen above, detecting misconfigured hardware and software to prevent public exposure of data is also a major issue for the healthcare industry. Those internal misconfigurations give hackers easy access to inflict damage.

For healthcare providers and hospitals, breaches reduce patient trust, cripple health systems and can even threaten human life. Since cybersecurity has become an integral part of patient safety, there is a growing demand for a holistic solution encompassing human behavior, technology and processes.  This means that healthcare providers should boost their cybersecurity to defend themselves against cybercriminals who are developing and using sophisticated tools and techniques for attacking healthcare organizations to gain access to medical information and hold data and networks for ransom. Although the healthcare sector has been lagging behind compared to other industries when it comes to cybersecurity, budgets have increased and new technologies are being purchased and deployed. This means that healthcare organizations are getting better at blocking attacks and keeping their networks secure, but still there is work to be done.

To help healthcare institutions with their efforts to protect their data, Cymulate offers them a convenient and easy way to test their cybersecurity posture. Cymulate’s Breach & Attack Simulation (BAS) platform allows a healthcare institution to run real cyberattacks in its own environment (at any time, from anywhere) in a safe manner without harming its network in any way. This allows them to test their security posture and mitigate cyberattacks before they can hit and penetrate the networks. The simulation also detects any misconfigurations for quick mitigation.
