NHS BT (blood.co.uk) - Advertisers and analytics

Context

NHS Blood and Transplant operates websites in the NHS portfolio. If you want an idea of how bad some of the rest of tne NHS has been, have a look now (26/08/2018) as it still includes a lot of tracking and advertisers. NHS England and NHS Digital have removed some of the similar tracking.

The privacy policy and cookie policy do not explain the extent to which you are tracked and instead go as far as to lie and suggest you are not tracked.

NHS BT has user accounts, and therefore collects user data. When they collect the data they don’t protect access control from third party advertisers loading JavaScript. For example, Facebook can not only track that you’ve signed up to blood.co.uk from cookies, they have access to read your email, date of birth, ethnicity, email, name and maybe more (I haven’t explored all features).

IPRO Cookies

There are more Cookies than they admit. Including advertising trackers

Facebook has access to user account data including Passwords

By replacing the Facebook JavaScript with a malicious script, I can extract form data. You can see ethnicity data, date of birth, email address, password, name and blood donation id number are all made available to Facebook.

Why does Facebook have this access?
