Normal browser security indicators in toolbars are only sometimes  
available to screenreaders.

But browsers often put up a warning page when a user tries to navigate to  
something marked as malware by a browser, and that page is generally  
"reasonably" accessible to screen reader users.

I think the common problems are:

1. email-based attacks, as you note. I believe some webmail services  
provide some protection from attachments, but I am not sure if dedicated  
email clients do the same.

2. Normal websites, that ask for sensitive information such as passwords  
which can be used to spend real money, on pages that are not secure. In  
many cases screen reader users don't *know* whether the page is secured.

As well as providing shortcuts to security information - which can be done  
in browsers today - having the ability to state the security state in the  
title of the page, so it cannot be faked by the page itself, would be a  
simple technique for browsers to implement.

cheers
