Late June 2017, Nuance Communications's system was taken down by NotPetya ransomware.  The intent of the attack was sabotage, resulting in permanent encryption of master file tables and preventing access of stored data. 

Healthcare is a large vertical that Nuance Communications serves, providing transcription services for hospitals. It took Nuance Communication weeks before it was able to bring most of their clients and their own transcription platform back online. Some hospitals have since moved to other service providers.
