Attached is a file with a name similar to Order_Confirmation-7069-2714739-20160815-292650.docm which contains a malicious macro. There are various versions, which according to my source (thank you) download a component from one of the following locations:

The payload is Locky ransomware with a very low detection rate at present. It phones home to:

185.129.148.19/php/upload.php (MWTV, Latvia)
138.201.56.190/php/upload.php (Hetzner, Germany)
46.148.26.77/php/upload.php (Infium UAB, Ukraine)

The MWTV block is all bad. Recommended blocklist:

Malware spam: This E-mail was sent from "CUKPR0329001" (Aficio MP C305).

This spam comes with a malicious attachment:

Subject:     Message from "CUKPR0317276"

Scan Date: 17.11.2015 09:08:40 (+0000)
Queries to: <scanner@victimdomain.tld

The email appears to come from within the victim's own domain (but this is just a simple forgery). Attached is a ZIP file with a name similar to 201608120908.zip which contains a malicious .WSF script with a name similar to doc(171)-12082016.wsf

This Hybrid Analysis shows the script downloading a file from www.hi-segno.com/02bjJBHDs?WUubFbrItd=ratyCr (and also the same location on bonmoment.web.fc2.com and www.homesplus.nf.net) but a trusted source tells me that the following download locations appear in different scripts:

185.129.148.19/php/upload.php (MWTV, Latvia)
138.201.56.190/php/upload.php (Hetzner, Germany)

That Latvian network range is all bad, I recommend that you block the lot. The payload is Locky ransomware.

The sender name and numbers in the subject vary, and it appears to come from within the sender's own domain (this is just a simple forgery).

Malware spam: "Please sign the receipt attached for the arrival of new office facilities." leads to Locky

Yet another Locky campaign today..

Subject:    please sign

Dear [redacted]

Please sign the receipt attached for the arrival of new office facilities.


Best regards,
Erica Hutchinson

This drops Locky ransomware through a malicious attachment. It appears to be largely the same as found in this earlier spam run.

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:
