Malware spam with random hexadecimal number leads to Locky

I only have a couple of samples of this very minimalist spam, consisting of just a "Subject" with a random hex number (e.g. 90027696CCCC611D) and a matching .DOCM attachment (e.g. 90027696CCCC611D.docm).

My trusted analysis source (thank you) says that these DOCM files contain a macro (no surprises there) that downloads a binary from the following locations:

blingberry24.com/90ujn3b8c3
danseduchat.com/90ujn3b8c3
harveyventuresltd.com/90ujn3b8c3
noveltybella.com/90ujn3b8c3
www.proxiassistant-ao.com/90ujn3b8c3
www.sacandolalengua.com/90ujn3b8c3

The payload is Locky ransomware with a detection rate of 3/52. The same source says that C2 locations are:

89.108.84.42 (Agava JSC, Russia)
148.163.73.29 (GreencloudVPS JSC, Vietnam)

Agava in particular is a regular source of badness, and I would suggest that you consider blocking the entire 89.108.80.0/20 range, or at least this minimum recommended blocklist:

89.108.84.42
148.163.73.29

UPDATE 2016-07-08

A variant of this spam run is in progress which adds the words RE, FW, Scan, Emailing or File to the random number. A trusted source (thank you) informs me that the download locations for the DOCM files in this case are:

abschlepp-taxi24.at/87yg5fd5
caijiachina.com/87yg5fd5
drpampe.com/87yg5fd5
felicecremesini.com/87yg5fd5
fermmedia.com/87yg5fd5
gebrauchtkauf.at/87yg5fd5
kurumenishimura.com/87yg5fd5
manutenzionecarrier.com/87yg5fd5
seferworld.com/87yg5fd5
snupress.com/87yg5fd5
themeidea.com/87yg5fd5

A malicious file is dropped with a detection rate of 3/55 which then phones home to the following server:

51.255.172.55 (OVH, France)

I recommend that you blog traffic to that IP.

Malware spam: "Scanned image" leads to Locky

This fake document scan appears to come from within the victim's own domain but has a malicious attachment.

From:    administrator8991@victimdomain.com
Date:    5 July 2016 at 12:47
Subject:    Scanned image

Image data has been attached to this email.

Possibly due to an error in setting up the spam run, there is an attachment named 05-07-2016_rndnum(4,9)}}.docm which contains a malicious macro. We haven't seen much in the way of Word-based malware recently. The two samples I received have VirusTotal detection rates of 5/52 and 6/52. The Malwr analysis for those samples [1] [2] shows the macro downloading a binary from:

leafyrushy.com/98uhnvcx4x
sgi-shipping.com/98uhnvcx4x

There will be a lot more locations too. This drops a binary with a detection rate of 5/55 which appears to be Locky ransomware. Hybrid Analysis shows it phoning home to:

185.106.122.38 (Host Sailor, Romania / UAE)
185.106.122.46 (Host Sailor, Romania / UAE)
185.129.148.6 (MWTV, Latvia)

Host Sailor is a notoriously Black Hat web host, MWTV has is problems too. The payload appears to be be Locky ransomware.

Recommended blocklist:
185.106.122.0/24
185.129.148.0/24

Malware spam: "Documents copies" / "I am sending copies of the documents as attachments."

This spam appears to come from various senders and has a malicious attachment:

From:    Eddie Savage

Subject:    Documents copies

Dear [redacted],

I am sending copies of the documents as attachments.

Thank you very much for your reply.

The payload is Locky ransomware. The command and control servers appear to be the same as found here and I recommend you block them.

Malware spam: "report" / "I致e attached the report you asked me to send." leads to Locky

This spam has a weird problem with its apostrophe and comes with a malicious attachment:

Hi info,

I致e attached the report you asked me to send.

Malware spam: "Updated" / "Attached please find the documents you requested.." / "King regards"

These two Hybrid Analyses [1] [2] show what appears to be Locky ransomware being downloaded from multiple locations. The dropped binary has a detection rate of 2/55. At present I don't have any C2 servers, but I would guess they are largely the same as the ones found here.
