Healthcare Data Breach Report for August 2023

Healthcare data breaches in August increased by 21.4% month-over-month. There were 68 data breaches involving 500 or more records that were reported to the HHS’ Office for Civil Rights. August is now the second-worst month of 2023 in terms of reported data breaches, considering the higher than the 2023 monthly average of 58.2 data breaches per month. To date, there are 463 healthcare data breaches reported this 2023, which is slightly higher than the 460 data breaches reported in the same period in 2022.

Although the number of breached records dropped by 34.3% month-over-month, July’s total was remarkably high. August had nearly 12 million exposed or stolen records reported, which is higher than the average of 7.49 million records per month in 2023.

To date in 2023, there are 71,479,579 records of individuals that were exposed or stolen. For the same time period last year, there were 29.27 million breached records, and 2022 was regarded as an awful year in terms of breached healthcare records. If the occurrence of healthcare data breaches remain at the current rate, 2023’s total will potentially reach 2015’s total of 112,466,720 breached records.

In August 2023, the HHS’ Office for Civil Rights received 26 data breach reports involving 10,000 and up records. Fifteen of the reported data breaches involved 100,000 and up records, and three had more than 1 million breached records. Fifteen of the 26 data breaches, including the month’s two biggest data breaches, were because of the massive exploitation of a zero-day vulnerability in the MOVEit Transfer file transfer solution of Progress Software. Progress Software released a security advisory about the vulnerability on May 31, 2023, and made a patch available on the same day to resolve the vulnerability; even so, the Clop group already exploited the vulnerability. The Clop group extracted information and demanded ransom payment, otherwise, the stolen data would be exposed on the group’s data leak website.

The enormity of the vulnerability exploitation is now getting clearer. As per Kon Briefing’s monitoring of the MOVEit attacks reports, 1,203 companies have confirmed being affected by the vulnerability exploitation, and the data of 54.2 to 59 million people were stolen. The ransomware remediation company Coveware states that the Clop group is estimated to have made $75 to $100 million from the ransomware attacks.

Three data breaches in August were due to ransomware attacks, though not all ransomware attacks are reported as such. The Royal ransomware group was responsible for two of the ransomware attacks on healthcare organizations. The Health Sector Cybersecurity Coordination Center released an alert about Royal ransomware last December 2022. CISA and the FBI also warned about Royal ransomware in a joint cybersecurity alert in March 2023.

Where did the Data Breaches Take Place?

These numbers do not reflect the entire story as the entity that submitted the report did not directly encounter the data breach. A lot of data breaches happened at business associates of HIPAA-regulated entities yet the covered entity reported the incident to OCR instead of the business associate.

The average and median breach sizes of a business associate data breach were 250,875 records and 10,037 records, respectively, compared to the health plans’ average and median breach sizes of 89,344 records and 8,487 records, respectively, and the healthcare providers’ average and median breach sizes of 83,425 records and 1,556 records, respectively.

HIPAA Enforcement Activity in August 2023

The HHS’ Office for Civil Rights declared one HIPAA enforcement action this August. OCR looked into a complaint against UnitedHealthcare and discovered a potential HIPAA Right of Access violation, as the provider failed to provide a patient with timely access to their requested health documents. The records were provided 6 months after the date they were requested. UnitedHealthcare stated the failure was because of an employee’s oversight and opted to negotiate the case and pay the penalty of $80,000. This enforcement action was the 45th under OCR’s HIPAA Right of Access to end in a financial penalty. The state attorneys general did not announce any HIPAA enforcement action in August. The FTC had not resolved any cases of violations of the FTC’s Health Breach Notification Rule or the FTC Act in August.
