A lot of HIPAA-covered entities provide the bare minimum information in their breach reports, just enough to meet the legal prerequisites for breach reporting and lessen the risk of exposing details that can be employed against them in case of a lawsuit. This minimalistic breach reporting is causing problems for breach victims as they are unable to properly determine the threat they face. They are unaware of how attackers are acquiring access to healthcare systems and the character of the attacks whether they are ransomware attacks or data theft/extortion attacks. Some breaches were reported in 2023 as hacking incidents with a chance of unauthorized access or data theft, wherein the threat actors listed the breached entity to their data leak sites.

Causes and Locations of Data Breaches

All the data breaches involving 10,000 or more records in December 2023 were hacking incidents, that is 62 incidents or 83.78% of the 74 data breaches and 11,283,128 records or 99.79% of breached healthcare records in December 2023. The average and median breach sizes were 181,986 records and 6,728 records, respectively. Something obviously must be done to increase resiliency to hacking incidents. Some action is being undertaken at the federal and state level.

In December 2023, OCR publicized its Healthcare Sector Cybersecurity Strategy, which discusses some steps that OCR is planning to enhance resiliency against cyber attacks in the healthcare industry and patient security. The reality of these plans will be dependent on Congress, which will provide the necessary funding. OCR is preparing to update the HIPAA Security Rule in 2024 and has mentioned that it will create voluntary cybersecurity targets for the healthcare industry. OCR is working with Congress to give financial support for domestic ventures in cybersecurity to help pay for the initial expense. The New York Attorney General has likewise declared that new cybersecurity requirements will be implemented for hospitals in New York following the big increase in cyberattacks, and that funds were provided to aid low-resource hospitals make the required upgrades.

Eight data breaches with 14,998 breached healthcare records were identified as unauthorized access/disclosure incidents. The average and median breach sizes were 1,875 records and 1,427 records, respectively. Four loss/theft cases with 8,285 breached records were reported in December. Two of the incidents concerned stolen documents and the other two involved lost electronic devices. The latter could have been prevented if encryption was employed.

The location of most hacking incidents was network services while 14 data breaches had the exposed or stolen PHI kept in email accounts. Three of these incidents had over 10,000 records exposed. According to the OCR data breach portal, healthcare providers had reported 49 data breaches involving 500 or more records in December with 3,730,791 breached healthcare records.

A lot of data breaches happen at business associates of HIPAA-regulated entities 0but the covered entity reported the breach to OCR. The average and median sizes of a business associate data breach were 314,354 records and 2,749 records, respectively; the average and median sizes of a healthcare provider data breach were 84,095 records and 5,809 records, respectively.

OCR additionally reported its first-ever settlement caused by a phishing attack investigation. Lafourche Medical Group based in Louisiana encountered a phishing attack that led to the compromise of the PHI of more or less 35,000 people. Although phishing attacks aren’t HIPAA violations, OCR’s investigation found several HIPAA Security Rule violations, such as no risk analyses before the 2021 phishing attack, and no measures to routinely evaluate records of system activity before the attack. Lafourche Medical Group decided to negotiate the investigation by paying a $480,000 penalty.

The total number of OCR enforcement actions involving financial penalties for 2023 is 13 with the total funds collected from these enforcement actions totaling $4,176,500. OCR is requesting Congress to raise the HIPAA violation penalties to deter violators and to give OCR the much-needed funds to take care of the backlog of HIPAA compliance investigations, particularly investigations regarding hacking cases. Presently, OCR is limited by the department’s funds which stayed the same for a long time even with yearly increases for inflation but still need to deal with the increased caseload of breach investigations.
