What This Report Covers
This report looks at ransomware against the U.S. healthcare sector, where attacks have caused large financial losses, service disruption and risk to patient safety. It covers attack trends and key statistics, from large hospital networks to rural facilities.
It profiles ransomware groups active in the sector, including LockBit, ALPHV/BlackCat and BianLian, and describes the cost of downtime, ransom demands and knock-on effects on regional care. Outdated systems, IoT devices and unpatched medical equipment are named as ways the attack surface grows.
The closing section is a defense roadmap, with backups, network segmentation and advice for resource-limited rural hospitals. For sector context, see the healthcare industry page.
Its audience is security leaders and clinical operations teams in healthcare. The report looks at what the sector has lived through and what a realistic resilience plan looks like, using real-world case studies from large systems.
The U.S. healthcare sector has become one of the most critical targets for ransomware groups, with attacks leading to billions of dollars in losses, widespread service disruptions, and—most importantly—risks to patient safety. From encrypted medical records and delayed surgeries to hospital shutdowns, ransomware has evolved into a systemic threat that directly impacts the quality and continuity of care.
