National Veterinary Associates (NVA), a California company that owns more than 700 animal care facilities around the globe, is still working to recover from a ransomware attack late last month that affected more than half of those properties, separating many veterinary practices from their patient records, payment systems and practice management software. NVA says it expects to have all facilities fully back up and running normally within the next week.
Agoura Hills, Calif.-based NVA bills itself as is the largest private owner of freestanding veterinary hospitals in the United States. The company’s Web site says it currently owns roughly 700 veterinary hospitals and animal boarding facilities in the United States, Canada, Australia and New Zealand.
NVA said it discovered the ransomware outbreak on the morning of Sunday, Oct. 27, and soon after hired two outside security firms to investigate and remediate the attack. A source close to the investigation told KrebsOnSecurity that NVA was hit with Ryuk, a ransomware strain first spotted in August 2018 that targets mostly large organizations for a high-ransom return.
The source told KrebsOnSecurity that NVA suffered a separate ransomware infestation earlier this summer that also involved Ryuk, and they expressed concern that the first incident may not have been fully remediated — potentially letting the attackers maintain a foothold within the organization.
“This is the second time this year Ryuk struck NVA,” the source said. “The first time, NVA was rather open to all facilities about what happened. This time, however, they are simply referring to it as a ‘system outage.’” Full story at KrebsOnSecurity: https://krebsonsecurity.com/2019/11/ransomware-bites-400-veterinary-hospitals/
