2020 Ransomware Attacks on U.S. Healthcare Providers

Ransomware Attacks on Healthcare Providers: As nationwide cases of COVID-19 continue to surge, hackers mercilessly double down on their extortion attempts on U.S. healthcare organizations. On October 28, the FBI and two federal agencies shared a notice of “credible information of an increased and imminent cybercrime threat to U.S. hospitals and healthcare providers.” Despite being faced with a global pandemic, hospitals are regrettably expected to face more data breaches and disruption to healthcare services from this looming Ryuk ransomware threat, potentially at a magnitude never seen before.

As a cybersecurity firm with many healthcare clients and deep industry experience, we have compiled an ongoing list of publicized 2020 attacks on U.S. healthcare providers as an awareness resource for the healthcare community. We will continue to update this page as we become aware of additional reported attacks.
