Cloud hosting provider iNSYNQ says it was hit with a ransomware attack that shut down its network and left customers unable to access their accounting data for the past three days. “Unfortunately for iNSYNQ, the company appears to be turning a deaf ear to the increasingly anxious cries from its users for more information about the incident,” reports Krebs On Security.” From the report: Gig Harbor, Wash.-based iNSYNQ specializes in providing cloud-based QuickBooks accounting software and services. In a statement posted to its status page, iNSYNQ said it experienced a ransomware attack on July 16, and took its network offline in a bid to contain the spread of the malware. “The attack impacted data belonging to certain iNSYNQ clients, rendering such data inaccessible,”; the company said. “As soon as iNSYNQ discovered the attack, iNSYNQ took steps to contain it. This included turning off some servers in the iNSYNQ environment.” iNSYNQ said it has engaged outside cybersecurity assistance and to determine whether any customer data was accessed without authorization, but that so far it has no estimate for when those files might be available again to customers.
