In this ransomware alert released Wednesday, Oct. 28, 2020: Ransomware Activity Targeting the Healthcare and Public Health Sector, the FBI and other federal agencies warned that cybercriminals are unleashing a wave of data-scrambling extortion attempts against the U.S. healthcare system that could lock up their information systems just as nationwide cases of COVID-19 are spiking.


This joint cybersecurity advisory was coauthored by the Cybersecurity and Infrastructure Security Agency (CISA), the Federal Bureau of Investigation (FBI), and the Department of Health and Human Services (HHS).
