@Bob: I think I missed something.  Is the link given above dangerous? 
I've altered it for safety here, but it would be unusual if it were.

The link is direct to a PDF (a format which is not entirely without its 
risks I suppose) but isn't embedded within a page that has JavaScript. 
Indeed, it's not an an HTML page at all.

So does the PDF itself contain ransomware, and if so which variant?  And 
how quickly after clicking the link did the encrypting begin?  I opened 
that PDF in Chrome an hour ago.  I have multiple backups, but it would 
be helpful to know if I need to budget time today to prepare for recovery.

If not, what link are you referring to?


@Richmond: why do you suppose the publisher doesn't have a domain name?
