(TNS) — Marin Community Clinics was hit with a ransomware attack Wednesday evening between 9 p.m. and 10 p.m. and hadn’t regained use of its computer systems yet by late Friday afternoon. Popat said the hackers locked down the clinics’ computer system and demanded a ransom before unlocking it. We don’t anticipate a major data loss, but we’re thinking there might be minor patient data loss just from recovering processes. “No patient data was compromised,” he said. In 2016, Marin Medical Practices Concepts, a Novato company that provides medical billing and electronic medical records services to many Marin physicians, had its computer system hacked and paid a ransom to regain access to its data. The Marin Healthcare District and Prima Medical Foundation later notified more than 5,000 patients that some of their medical data was lost due to a glitch that followed the ransomware attack.
