Order invoice ID Purchase order ID Order Invoice Copy ID emails with an attached exel document containing a macro.
These emails aren't from these companies at all , they are just being used to make the email look more genuine, ie. from a real company.
Note
It's also worth remembering that the company itself may not have any knowledge of this email and it's link(s) or attachment as it won't have come from their servers and IT systems but from an external bot net.
It's not advised to ring them as there won't really be anything they can do to help you. |

NOTE
The current round of Word/Excel/XML attachments are targeted at Windows users.
Apple and Android software can open these attachments and may even manage to run the macro embedded inside the attachment.
The auto-download file 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 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.
Currently these attachments try to auto-download Dridex, which is designed to
steal login information regarding your bank accounts (either by key logging, taking auto-screens hots or copying information from your clipboard (copy/paste)) |
Cheers,
Steve

Well done, Steve. Always find you the first to react to these! We received 2 variants of this in the past 20 mins.
We are running exchange 2010, i have added a transport rule for any .xlsx or .doc attachments which prefixed the subject with "Suspicious attachment" and adds a disclaimer at the bottom of the message body advising the user to delete the message if they weren't expecting it.
Hopefully this info will help somebody else
