Two-Thirds of Healthcare Organisations Hit by Ransomware – A Four-Year High, Sophos Survey Finds

Sophos, a global leader of innovative security solutions for defeating cyber attacks, released a sector survey report, “The State of Ransomware in Healthcare 2024,” which revealed that the rate of ransomware attacks against healthcare organisations has reached a four-year high since 2021. Of those organisations surveyed, two-thirds (67%) were impacted by ransomware attacks in the past year, up from 60% in 2023. The rising rate of ransomware attacks against healthcare institutions contrasts with the declining rate of ransomware attacks across sectors; the overall rate of ransomware attacks fell from 66% in 2023 to 59% in 2024.

Alongside an increase in the rate of ransomware attacks, the healthcare sector reported increasingly longer recovery times. Only 22% of ransomware victims fully recovered in a week or less, a considerable drop from the 47% reported in 2023 and 54% in 2022. In addition, 37% took more than a month to recover, up from 28% in 2023, reflecting the increased severity and complexity of attacks.

“While we’ve seen the rate of ransomware attacks reach a kind of “homeostasis” or even decline across industries, attacks against healthcare organisations continue to intensify, both in number and scope. The highly sensitive nature of healthcare information and the need for accessibility will always place a bullseye on the healthcare industry from cybercriminals. Unfortunately, cybercriminals have learned that few healthcare organisations are prepared to respond to these attacks, demonstrated by increasingly longer recovery times. These attacks can have immense ripple effects, as we’ve seen this year with major ransomware attacks impacting the healthcare industry and impacting patient care,” said John Shier, Field CTO, Sophos.

“To combat these determined adversaries, healthcare organisations must adopt a more proactive, human-led approach to threat detection and response, combining advanced technology with continuous monitoring to stay ahead of attackers.”

Additional findings from the report include:

• Ransom Recovery Costs Surge: The mean cost of recovery in a healthcare ransomware attack was $2.57 million in 2024, up from $2.2 million in 2023 and double the 2021 cost
• Ransom Demands vs Payments: 57% of healthcare institutions that paid the ransom ended up paying more than the original demand
• Root Cause of Attack: Compromised credentials and exploited vulnerabilities were tied for the number one root cause of attack, each accounting for 34% of attacks
• Backups Targeted: 95% of healthcare organisations hit by ransomware in the past year said that cybercriminals attempted to compromise their backups during the attack.
• Increased Pressure: Organisations whose backups were compromised were more than twice as likely to pay the ransom to recover encrypted data (63% vs. 27%)
• Who Pays the Ransom: Insurance providers are heavily involved in ransom payments, contributing in 77% of cases. 19% of total ransom payment funding comes from insurance providers

The latest Sophos report on real-world ransomware experiences explores the full victim journey, from attack rate and root cause to operational impact and business outcomes, of 402 healthcare organisations. The results for this sector survey report are part of a broader, vendor-agnostic survey of 5,000 cybersecurity/IT leaders conducted between January and February 2024 across 14 countries and 15 industry sectors.
