For the fourth successive month, the number of reported healthcare data breaches has fallen. In March 2022, 43 healthcare data breaches of 500 or more records were reported to the U.S. Department of Health and Human Services’ Office for Civil Rights (OCR), which is a 6.52% fall from February and well below the 12-month average of 57.75 data breaches a month.
However, there was a 36.94% increase in the number of breached records compared to February. Across the 43 reported breaches, 3,083,988 healthcare records were exposed, stolen, or impermissibly disclosed, which is slightly below the average of 3,424,818 breached records a month over the past 12 months.
Largest Healthcare Data Breaches in March 2022
In March 2022, there were 25 data breaches reported to OCR that affected 10,000 or more individuals, all but one of which were hacking incidents. The largest data breach of the month affected over half a million patients. Christie Business Holdings Company, which operates Christie Clinic in Illinois, discovered an employee email account had been accessed by unauthorized individuals and was used in a business email compromise (BEC) attack to try to divert payment to a third-party vendor. BEC attacks may account for a relatively small percentage of healthcare data breaches, but according to figures from the FBI, they are the biggest cause of losses to cybercrime.
SuperCare Health reported a major breach from July 2021 where hackers accessed its network and potentially stole patient data. Around two weeks after announcing the data breach the first lawsuit against SuperCare Health was filed. There is often a rush to file lawsuits following healthcare data breaches, and it is now common for multiple lawsuits to be filed.
CSI Laboratories reported a cyberattack that was discovered in February. While the nature of the attack was not disclosed, the Conti ransomware gang claimed responsibility for the attack and published a sample of the stolen data on its data leak site to pressure the lab into paying the ransom. Double extortion tactics, where payment is required for the keys to decrypt files and to prevent the publication of stolen data, are now the norm in ransomware attacks.
