Important notes:

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

Apple and Android mobiles/tablets can open these attachments and may even manage to run the macro embedded inside the attachment but they will be safe

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

However, if you are an Apple/Android user and forward the message to a Windows user, you will them 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 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 the the company themselves, as there won't really be anything they can do to help you.



Cheers,
Steve
