Cyber Attacks: In the Healthcare Sector

 

As the healthcare sector continues to offer life-critical services while working to improve treatment and patient care with new technologies, criminals and cyber threat actors look to exploit the vulnerabilities that are coupled with these changes. The following blog series will explore one MS-ISAC analyst’s thoughts on today’s sources of frustration for healthcare IT and cybersecurity specialists.

The healthcare industry is plagued by a myriad of cybersecurity-related issues. These issues range from malware that compromises the integrity of systems and privacy of patients, to distributed denial of service (DDoS) attacks that disrupt facilities’ ability to provide patient care.

While other critical infrastructure sectors experience these types of attacks, the nature of the healthcare industry’s mission poses unique challenges. For healthcare, cyber-attacks can have ramifications beyond financial loss and breach of privacy. Ransomware, for example, is a particularly egregious form of malware for hospitals, as the loss of patient data can put lives at risk.

Each link below leads to a discussion of that unique type of attack in the healthcare sector. These articles include real-life examples of how the attack manifested, the damage and disruption it caused or could have caused if not handled properly, and suggestions on how to defend against or mitigate each type.

This is by no means an exhaustive list of the types of attacks hospitals face but, rather, a summary of some of the major and most costly incidents affecting hospitals.

U.S. hospitals can get access to Malicious Domain Blocking and Reporting (MDBR) to help defend against ransomware at no cost.
