Dental practices are reporting to Henry Schein Practice Solutions that they have received calls from an individual posing as a company employee who then asks for remote access to the office servers. The company in late January stated that, according to the practices, the callers provided multiple reasons for their calls, such as communicating problems with computer system backups and viruses and hardware failures, before requesting access to the system.
