The biggest healthcare data breaches of 2021. More than 40 million patient records have been compromised this past year by incidents reported to the federal government in 2021.

Amidst warnings from the U.S. Federal Bureau of Investigation about hacking groups and news from the Department of Justice about ransomware-related arrests, an adage has begun to be repeated among cybersecurity professionals: It’s not “if” an attack will happen, but “when.”

And 2021 has been a particularly dire year for healthcare data breaches, with incidents taking down networks for weeks at a time and potentially leading to disruptions of care throughout the country.

To add insult to injury, some hospitals even face legal action after restoring access to their network. Overall, 40,099,751 individuals’ records have been affected by exposures reported to the federal government so far this year.

For anyone who needs a refresher on how things have gone, Healthcare IT News has compiled a list of the 10 largest data breaches reported to the U.S. Department of Health and Human Services’ Office of Civil Rights this year so far:
