Malware spam: "Image data has been attached to this email." / "Scanned image"

This spam is presumably meant to have a malicious attachment, but all the samples I have seen are malformed:

From:    support398@victimdomain.tld

Subject:    Scanned image

The spam appears to come from within the victim's own domain (but doesn't). In case you don't recognise all those random letters, that's what an email attachment looks like.. but something has gone badly wrong with this spam run. I haven't analysed the payload, but it is likely to be Locky ransomware as found here.

Malware spam: "Sent from my Samsung device" leads to Locky

This rather terse spam has a malicious attachment:

From:    Ila
Date:    18 July 2016 at 13:01
Subject:    scan0000511

Sent from my Samsung device

The sender and subject vary, but the subject seems to be in a format similar to the following:

scan0000511
SCAN000044
COPY00002802

Attached is a .DOCM file with the same name as the subject. Analysis by another party (thank you!) shows the macros in the document downloading from one of the following locations:

bursaforex.home.ro/54ghnnuo
car-sound.go.ro/54ghnnuo

pichuile.free.fr/54ghnnuo
sgvillage.com/54ghnnuo
static.indirveoyna.com/54ghnnuo
www.carboplast.it/54ghnnuo

The payload is Locky with a detection rate of 4/53. It phones home to:

77.222.54.202 (SpaceWeb CJSC, Russia)
91.240.86.221 (JSC Server, Russia)

That's a subset of the IPs found here, so I recommend you block the following IPs:

77.222.54.202
91.240.86.221
176.111.63.51
209.126.112.14 

Malware spam: "bank account report" leads to Locky

This fake financial spam has a malicious attachment:

From     "Boyd Dennis"
Date     Mon, 18 Jul 2016 11:34:11 +0200
Subject     bank account report


How is it going?

Thank you very much for responding my email in a very short time. Attached is the
bank account report. Please look at it again and see if you have any disapproval.

The sender name and details vary, although it all follows the same pattern. Attached is a ZIP file containing elements of the recipients email address and some random digits.

I don't have a copy of the payload at present, but it does phone home to:

77.222.54.202 (SpaceWeb CJSC, Russia)
91.240.86.221 (JSC Server, Russia)
176.111.63.51 (United Networks Of Ukraine Ltd , Ukraine)
209.126.112.14 (MegaHosterNetwork, Ukraine)

The payload appears to be Locky ransomware.

Malware spam: "Please find attached the profile of Mr.X for a suitable role in your Organisation" leads to Locky

This spam comes with a malicious attachment, it appears to come from different senders and the referenced name varies, but the format is essentially the same.

From:    Effie Larsen
Date:    12 July 2016 at 20:07
Subject:    Profile

Dear [redacted],

Please find attached the profile of Mr.Welch for a suitable role in your Organisation


King regards,
Effie Larsen
Mexico Key Account Director

Attached is a ZIP file containing elements of the recipient's email address, the word "profile" and a random number. Contained within are a variety of malicious .js scripts beginning with "profile".

These two Hybrid Analysis reports [1] [2] show download locations at:

jstudio.com.my/wtxyf4
zakagimebel.ru/nrik9xq

This is somewhat consistent with the download locations for the earlier Locky ransomware spam as seen here. It is likely that the C2 servers are the same or at least overlap.

Malware spam: "Here's that excel file (latest invoices) that you wanted." leads to Locky

This fake financial spam leads to Locky ransomware:

From:    Benita Clayton
Date:    12 July 2016 at 15:04
Subject:    Fw:

hi [redacted],

Here's that excel file (latest invoices) that you wanted.


Best regards,
Benita Clayton
Vice President US Risk Management

Sender details vary from message to message. Attached is a ZIP file containing part of the recipient's email address plus some other elements, within which is a malicious. js script beginning with -SWIFT-.

Trusted external analysis (thank you again) shows the scripts download an obfuscated binary from one of the following locations:
