🚨 Cybersecurity in healthcare is more critical than ever as cybercriminals continue to exploit vulnerabilities in hospital networks, leading to data breaches, system lockdowns, and massive ransom demands. At HIMSS25 in Las Vegas, industry experts gathered to discuss the evolving ransomware attack chain and how healthcare organizations can better defend against these growing threats.

🔗 Healthcare Innovation – Understanding the Ransomware Attack Chain
🛡️ How Cybercriminals Target Healthcare Systems
At the HIMSS Cybersecurity Forum, Erik Decker, VP & CISO of Intermountain Health, and Shawn Anderson, Cybersecurity Director, detailed how attackers infiltrate healthcare systems using:
✔ Social Engineering – Manipulating employees into giving access.
✔ Third-Party Compromises – Exploiting vendor and partner system weaknesses.
✔ System Vulnerability Exploits – Attacking outdated or unpatched software.
✔ Stolen Login Credentials – Using compromised usernames and passwords to gain entry.
💀 The Ultimate Goal: Control Systems & Privileged Access
Once inside, hackers aim to access the Active Directory, where they can escalate privileges, steal sensitive data, and deploy ransomware to cripple entire hospital networks.
🔴 “If you want to cause damage, you need to get to the control systems,” Decker explained, highlighting the need for rapid detection and response strategies.
💡 Key Takeaways from HIMSS25: Protecting Healthcare from Ransomware
🔹 Patching & System Updates Are Critical – Vulnerabilities should be patched within 72 hours to prevent attackers from exploiting weak points.
🔹 Multi-Factor Authentication (MFA) Must Be Enforced – Prevents unauthorized logins, even if credentials are stolen.
🔹 Incident Response Planning Saves Lives – Hospitals must test and refine their cybersecurity response before an attack happens.
