Healthcare Cybersecurity: Exploitation Trends & Layered Defense
- While patching vulnerabilities remains a cornerstone of cybersecurity, a recent report highlights that the most commonly patched flaws aren't always the ones most actively exploited by attackers.
- According to SonicWall's threat research, elevation of privilege (EoP) bugs, though frequently enough less visible, accounted for 38% of actual attacks.
- The report also found that security feature bypass methods, representing just 8% of known vulnerabilities, were responsible for 29% of exploits.
Healthcare organizations face mounting pressure to refine their cybersecurity strategies. Recent reports reveal a critical truth: the most patched vulnerabilities aren’t always the most exploited. This necessitates a shift towards prioritizing patches based on real-world attacker behavior,not simply vulnerability volume. Elevation of priviledge bugs and security feature bypass methods are key targets. Layered defenses and real-time detection are essential for robust protection.News Directory 3 understands the need for healthcare cybersecurity awareness and provides actionable insights.

healthcare Organizations Must Prioritize Cybersecurity Patches Based on Real-World Exploits
Updated June 27, 2025
While patching vulnerabilities remains a cornerstone of cybersecurity, a recent report highlights that the most commonly patched flaws aren’t always the ones most actively exploited by attackers. This underscores the need for healthcare organizations to strategically prioritize their patching efforts, focusing on vulnerabilities that pose the greatest real-world risk.
According to SonicWall’s threat research, elevation of privilege (EoP) bugs, though frequently enough less visible, accounted for 38% of actual attacks. In contrast, remote code execution flaws, wich comprised 40% of all vulnerabilities, were linked to only 19% of exploits. This disparity reveals that attackers often target vulnerabilities that offer the “most rewards and least resistance,” according to Douglas McKee, executive director of threat research at SonicWall.
The report also found that security feature bypass methods, representing just 8% of known vulnerabilities, were responsible for 29% of exploits. This further emphasizes the importance of understanding attacker behavior when determining patching priorities. Healthcare organizations should play a key role in understanding these threats.
The volume of vulnerabilities alone should not dictate patching strategies. Instead, healthcare organizations should focus on how attackers behave in the real world to strengthen their cybersecurity posture.
Even predictions from industry leaders can be undone by real-world cybercriminal behavior. Such as, Microsoft labeled 123 vulnerabilities as “Exploitation More Likely” in 2024, but only 10 made it onto the Cybersecurity and Infrastructure Security Agency’s Known Exploited Vulnerabilities Catalog.
“With over 1,000 vulnerabilities patched and millions of associated threats blocked, one thing is clear: Patching alone isn’t enough,” said McKee. “Attackers are moving faster than ever to exploit the paths that provide the most rewards and least resistance.”
What’s next
To stay ahead of evolving threats, healthcare organizations must adopt layered, proactive defenses that combine real-time detection and response with comprehensive protections across all attack surfaces. McKee recommends prioritizing the identification of privilege escalation attempts, neutralizing malware in Office documents, blocking exploits before they reach users, and integrating security across endpoints, email accounts, and networks. Organizations that invest in coordinated, intelligence-driven security are better positioned to anticipate and neutralize threats.
