A server used to store real-time recordings of phone calls made to the 1177 Swedish Healthcare Guide service for health care information was found completely exposed to the Internet with no user or password to protect it. The server was used as a storage device by MediCall, a subcontractor with Swedish owners from Thailand, for the Biz 2.0 cloud-based call center system developed by Swedish company Voice Integrate Nordic AB. MedHelp is the company which runs the service under an agreement with Swedish county councils, regions, and municipalities.
