Allscripts's North Carolina data centers were struck by SamSam ransomware Jan. 18, knocking out its Professional EMR and electronic prescribing services, among other features. Only customers who host their data on the Allscripts cloud felt the attack's wrath, because the vulnerability that was exploited wasn't within an Allscripts application. While the vendor claims no patient data has been compromised, a number of physicians have expressed frustration with the EMR lockdown — and others have had to turn patients away. Pulmonary Physicians in Canton, Ohio, told News 5 they had no choice but to cancel appointments. Without access to patient records, physicians at the clinic — which sees nearly 8,500 patients — couldn't provide proper care. "It has prevented us from being able to see patients in the office," George Kefalas, MD, told News 5. Scheduling, test results and medications have been offline at Pulmonary Physicians since the attack began.
