If you receive such a message containing an HTML page attached, don’t open it.
The email pretends to come from “craigslist – automated message, do not reply <email@example.com>” and has the subject ”Efax Corporate”.
What I find interesting is that the fraudsters didn’t even bother to write JS code to
detect if the script runs in Internet Explorer or not. They write now in the email’s text
“View attached fax using your Internet Browser.” and in the attached document
<h2><b>Please wait a moment… You will be forwarded…</h2></b><br>
<h4>Internet Explorer / Mozilla Firefox compatible only</h4><br>
The attached document contains a malicious java script code which would download malware on your computer.
All Avira products detect this as “HTML/Redir.EB.8” and “JS/Column.EB.18”.
