Data? What data?
-> queried the nature of the data that was exfiltrated
I'm glad The Reg has asked that. We often read in reports about "limited number of customers" and "some customer data" and so on, which is the PR equivalent of "how long is a piece of string". I have no reason to believe that Advanced is being economical with its account, but it would be better if they expressed it more clearly.
-> Advanced has now informed those customers
Customers being the NHS trusts and whatever that they provide services to, but presumably not to the subjects of the affected data?
