Malware spam: "Emailing: Sheet / Document / Invoice" with a .docm leads to Locky

This malware-laden spam comes with a variety of subjects, for example:

Emailing: Invoice (79).xls
Emailing: Sheet (189).doc
Emailing: Sheet (3352).tiff
Emailing: Document (79).doc
Emailing: Invoice (443).doc
Emailing: Sheet (679).xls
Emailing: Document (291).pdf


There is no body text. Attached is a .docm file with the same prefix as the subject (e.g. Document (291).pdf.docm) which contains a macro that downloads a malicious component from one of the following locations:

(Thank you to my usual source for this). The payload is Locky ransomware and the C2 servers are those found here.

Thanks, we've been getting this for a few days already.
Is there a list of IP's available of where the emails are originating from?
So far Barracuda RBL has been doing a decent job blocking it.

I got this as invoice(29).docm in my junk mail folder but it was smart enough (or being watched enough by an individual) to then send an allow sender request to my regular email.
Where do you think they picked up my address?

Just received an email with the sender my own email address. Subject line--Emailing: Sheet (7019).doc. No body content and just an attachment. The IP address for the source is 85.105.148.241, which Google tells me is Istanbul, Turkey.

I inadvertently opened this file on my droid phone..
What concerns should I have?

Thank you for this information. I never trust these kind of emails and a confirmation on websites like yours are a great reassurence that I choose right ;-)
