teckentrupdepot.co.uk have put a note about the issue and updated their website:

Important Information
We are currently experiencing an IT issue where one of our email addresses has been spoofed. If you have received an email with a suspicious attachment then please delete it. You need do nothing further as we have identified the machine which is outside of our organisation and are working with them to remedy the problem. Sorry for any inconvenience.




NOTE


The current round of Word and Excel 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))
