Windsor Flowers Invoice 1385 Accounts word malware

Windsor Flowers Accounts Invoice 1385 email being spammed containing a word document with embedded macro.

These emails aren't from Windsor Flowers at all, they 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 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))

Cheers,
Steve

Hi - just analysed it:

Connects to: hxxp://vivercomrequinte.com/br/js/bin.exe
Creates file: %TEMP%\sdfsdferfwe.exe

and executes it.

Hi
I opened the email, but not the attachment...am I safe from infection as you said about auto download or is only once I open the attachment with macro's enabled?

i have now deleted the email & run Malwarebytes

regards
Nigel

Nigel, if you opened the attachment on a windows machine with macros enabled then it's wise to scan.

If you just received the email, without opening anything/clicking, you should be ok.

I just opened the email not the attachment.....

& then deleted it.

Nigel: You should be ok then, still worth a Malwarebytes scan though.

Hi Steve

I have run the free version of malwarebytes & no malware was reported...i assume this should find all known malware?

Regards Nigel

Sorry, stupid typo:

The domain is a .com.br



Connects to: hxxp://vivercomrequinte.com.br/js/bin.exe
Creates file: %TEMP%\sdfsdferfwe.exe
And executes it.

Hi Steve.
I actually ordered flowers on the date at the top of the spam email. I was;t paying any attention and clicked on the attachment. I had a message on my Microsoft Word. (I can't remember what it said) and then it opened a blank document. I started paying attention then and realized what the email was. I am using a Mac. Do you think I will have trouble? Any suggestions?

Thank you.
Laurie
