Two more healthcare organizations have acknowledged in the last week that they were victims of what looks to be ransomware attacks on their servers.
For one, Greenbrae, Calif.-based Marin Healthcare District (MHD) received notice in late July that Marin Medical Practices Concepts, Inc., (MMPC), the company that provides MHD with business and healthcare system services, experienced a ransomware infection. More than 5,000 patients were then notified that some of their medical data was lost due to a glitch that followed the ransomware attack, according to the Marin Independent Journal.
According to the Independent Journal report, the security incident also affected patients of physicians with Prima Medical Group who work with Marin General Hospital. In that story, Lynn Mitchell, CEO of Marin Medical Practice Concepts, confirmed the malware attack. In an email to the Independent Journal, Mitchell wrote, “Ransom was paid. For security reasons we will not be releasing the amount or denomination paid.”
And, according to a privacy notice on the organization’s website, although a third-party forensic firm hired to investigate this incident found no evidence that patient personal, financial, or health information was accessed, viewed, or transferred, during the restoration process, one of MMPC’s backup systems failed, causing information to be lost that was collected at the district’s nine medical care centers during a two-week span in July.
This information includes vital signs, limited clinical history, documentation of physical examinations, and any record of the communication between patients and their physician during a visit in that 15 day period. Results of diagnostic tests were not lost and patients do not need to be re-tested, officials said. MHD is mailing letters to potentially affected individuals and has established a call center to address questions or concerns.
Meanwhile, Oxford, Miss.-based Urgent Care Clinic of Oxford also has admitted that it has been the victim of a criminal cyber attack that may have affected the personal information of current and former patients. According to databreaches.net, in a notification letter to affected patients, the organization said that sometime in early July, its server was hacked. The breach was discovered on August 2nd when staff noticed the computer system running more slowly than usual. From the sound of their notification, it sounds like the clinic paid a ransom demand, the website noted: “The hackers held the server for ransom before turning control back over to the Urgent Care staff.”
That report also stated that the clinic has claimed that a forensic investigation suggested that the attack was carried out by Russian hackers. The types of protected health information (PHI) on the server included patients’ names, social security numbers, dates of birth, and other personal information, as well as any health information on file. The clinic was unable to determine which patients, specifically, may have been affected by the breach, the report stated.
