Just received an email with the title “Corporate eFax message from “01264074629″ – 1 page” ( number of pages will probably vary in each email).

The email comes in from a  spoofed email address “eFax Corporate <message@inbound.efax.com>” and has the following text in its body:

Fax Message [ Caller-ID: UNAVAILABLE]

You have received a 1 page fax at Tue, 25 Feb 2014 18:10:08 +0300 GMT.
The reference number for this fax is 1726-913 .

To view this message, please open the attachment.

For any questions or problems, please contact eFax Support.

There is a ZIP file attached to the email which supposedly had the faxed document inside it , mine had the name efax_272784611A.zip and contained a 146 kB  file eFax_723645.9428754.pdf.exe

This as you’ll probably guess is not a pdf/fax, it a virus/trojan payload, that’s just waiting for you the unsuspecting recipient to open.

The easiest way to deal with these emails is delete them as soon as they arrive in your inbox, if however you are unlucky enough to open and run the pdf.exe, best thing to do is disconnect your PC from the internet or any networks your attached to, download something like Malwarebytes/Superantispyware on another pc and then boot your PC into Safe mode and then install and run, hopefully either one of these should find any suspicious files, I’d then suggest downloading a free anti-virus software like AVG or Avast and run these as well to see if there are any other nasties hiding away on your PC.

Hopefully you wont need to do any of this and will have googled” efax email” and found mine or someone else’s blog explaining exactly what it is
