HHS warns of increasing zero-day attacks in healthcare

The U.S. Department of Health and Human Services issued a cybersecurity briefing warning health systems about the threat of “zero-day attacks.” Zero-day attacks occur when hackers weaponize an unknown vulnerability in a system to target the flaw before the developers have identified it. Perhaps the most famous zero-day attack to date occurred in 2010 when the Stuxnet worm exploited multiple vulnerabilities in Windows systems and reportedly destroyed multiple centrifuges at a nuclear power plant in Iran.
