Has anyone child’s personal information get taken from the hospital. Like my hospital sent me a letter stating that they got an email and few employees fell for it and when they opened it, it gave the hacker access to patients accounts(name, doctor, home address etc) an that the hacker was only going after Childern’s information. I’m not sure what to do. Any advice?
