São Paulo-based medical diagnostic firm Grupo Fleury has suffered a ransomware attack that has impaired business operations after the company shut down its systems. On the 22nd of June, the company website began displaying an alert message, alerting to the fact that its systems were suffering an attack and are no longer accessible.

Brazilian healthcare giant provides medical laboratory services across the nation with over 200 service centers and more than 10,000 employees. The company performs approximately 75 million clinical exams in a year.

“Please be advised that our systems are currently unavailable and that we are prioritizing the restoration of services. The causes of this unavailability originated from the attempted external attack on our systems, which are having operations reestablished with all the resources and technical efforts for the rapid standardization of our services,” read the message translated into English. 

With their systems being knocked down, patients are unable to book appointments for labs and other medical examinations online. Since the announcement, multiple cybersecurity sources have confirmed that Grupo Fleury suffered an attack by the ransomware operation known as REvil, also known as Sodinokibi.
