Important notes:

The current round of Word/Excel/XML/Docm attachments are targeted at Windows users.

Apple, Android and Blackberry mobiles/tablets that open these attachments will be safe

The auto-downloaded/payload is normally a Windows executable and so will not currently run on  any operating system, apart from Windows.

However, if you are an Apple, Android or Blackberry user... and forward the message to a Windows user, you will then put them at risk of opening the attachment and auto-downloading the malware.

These word/excel attachments normally try to download either...

    Dridex banking trojan,
    Shifu banking trojan

... both of which are designed to steal login information regarding your bank accounts either by
key logging, taking screen shots or copying information directly from your clipboard (copy/paste)


It's also worth remembering that the company itself  may not have any knowledge of this faked email and any link(s) or attachment in the email normally won't have come from their servers or IT systems but from an external bot net.

These bot-net emails normally have faked email headers/addresses.

It's not advised to ring/email the the company themselves, as there won't really be anything they can do to help you or to stop the emails being spread.



Cheers,
Steve

We had loads come in before this one from scanner@ which have the same payload, one of which is downloaded from hxxp://kdojinyhb.wz.cz/87yte55/6t45eyv.exe

Same filename as yesterday, but different content (our antivirus didn't complain when I downloaded a sample)
