Hackers have known for years that hospitals and other health care providers make perfect targets for ransomware attacks, since there's life-or-death urgency in getting back up and running quickly. During the pandemic, though, the risk has become even more dire. After a hospital in the Czech Republic was hit by a debilitating ransomware attack in March, the country's cybersecurity oversight agency warned two weeks ago that it was bracing for widespread cyberattacks against critical services in the country. Two Czech hospitals reported attempted attacks a day later, and the US State Department threatened consequences if the antagonism continued.
