Sometime between June 30 and August 15, 2013, an unknown third party accessed the electronic network of a business associate (BA), Blackhawk Consulting Group. The types of protected health information (PHI) involved in the breach included the names, mailing addresses, email addresses, and credit card information of 998 patients of the covered entity (CE), Dreyer Medical Clinic. The CE provided breach notification to HHS and the CE and BA provided notification to affected individuals and the media, as well as substitute notification. To mitigate the breach, the BA attempted to identify and remove malicious code which led to the hacking and audited its website, servers, and networks. The CE terminated its BA relationship with the BA. OCR obtained documented assurances that the CE and BA implemented the corrective actions noted above.
