My inbox listed an email message with the Subject:
April Hill shared "UPDATE Agreement_22-01-2016.zip" with you.
I have to admit, it's a pretty good imitation, complete with a carefully-placed Dropbox logo (downloaded live from dropbox.com if you foolishly load images) and clean HTML design. The only obvious flaw was an incorrect character in place of the copyright symbol.
I want to hope that any recipient not expecting a Dropbox document from April Hill (or any unknown name) would be suspicious and not blindly click on the "Click here to view." link in the message. Rolling the cursor atop the link would instantly reveal a URL not pointing to dropbox.com.
Downloading the phony file and opening it is how personal computers and business networks get infected by all kinds of Bad Guys. "Danger, Will Robinson!"
