Official notice

On March 6, 2019, Maffi Clinics (“Maffi”) submitted a breach notification report to OCR indicating that on September 11, 2018, it was the victim of a ransomware attack. Maffi promptly identified and terminated the unauthorized access point, isolated and removed the ransomware, and restored all of Maffi’s data. The incident affected 10,465 patients’ clinical and demographic information, although Maffi found no evidence that any of its data was viewed or downloaded. On February 14, 2019, Maffi provided written notification to the affected patients, including information on credit monitoring, and posted information regarding the incident on its website. OCR determined through its investigation that Maffi is not a HIPAA covered entity or business associate and closed the investigation as a result.
