Ransomware has rapidly escalated from being a financial nuisance to a significant, multi-dimensional threat that jeopardizes the core of our most essential services. Sectors like healthcare, education, and government are particularly vulnerable, where a single attack can cripple critical operations, expose sensitive information, and, in the most severe cases, put lives at risk.
This post summarizes ransomware trends for these critical and essential sectors based on findings from new ransomware research by ThreatLabz: Healthcare, Education & Public Sector Insights: Zscaler ThreatLabz 2024 Ransomware Report.
The alarming rise of ransomware attacksOver the past year, ransomware attacks have surged in frequency and boldness fueled by generative AI advancements.
