The senders vary from email to email. Attached is a ZIP file with a malicious script, which in the examples that I have found downloads one of a variety of malicious executables [1] [2] [3] [4] which call home to the same IP addresses found in this earlier spam run.

Malware spam: "Neue Abrechnung Nr. 746441" / support@sipcall.de

This German-language spam has a malicious attachment:

Reference numbers vary. Attached is a randomly-named Word document (e.g. INV842038-746441.docm). The sample I submitted to Malwr showed it downloading a binary from:

www.ding-a-ling-tel.com/98yh87nb6v4

There are probably other locations too.

An executable is dropped with a detection rate of 3/56. The Hybrid Analysis and DeepViz report both indicate different phone-home locations:

193.9.28.13 (FLP Kochenov Aleksej Vladislavovich / uadomen.com, Ukraine)
5.152.199.70 (Redstation, UK)


Private sources also indicate C2s at:

212.109.219.31 (JSC Server, Russia)
107.181.187.12 (Total Server Solutions, US)


The payload is Locky ransomware.

Phish: "Final PO Contract..xlsx"

The link in this email goes to:

cagselectrical.com.au/libraries/emb/excel/excel/index.php?email=[redacted]

This gives a pretty convincing looking facsimile of an Excel spreadsheet, prompting for credentials..


Entering any combination of username and password seems to work, then you get redirected to a GIF of a spreadsheet..


Curiously, this GIF is not part of a phishing site but is on a wholly legitimate site belonging to a software company called Aspera (you can see it here):

download.asperasoft.com/download/docs/console/2.0/linux/html/images/console/console-report-ex1-xls.gif

The asperasoft.com domain is NOT involved in the phishing nor has it been compromised. As ever, I would advise you not to explore links like this as they might lead to an exploit kit or malware, and bear in mind that some phishing pages are better than others, and this is one of the more convincing ones that I have seen recently.

Malware spam: "Please find attached a document containing our responses to the other points which we discussed.."

This spam appears to come from different companies and senders, and has a malicious attachment:

From:    Sara Osborne

Subject:    RE:

Dear sales,

Please find attached a document containing our responses to the other points which we
discussed on Monday 23th May.

Please let me know if you have any queries


Regards,

Wayfair Inc.

Sara Osborne
Attached is a ZIP file (the ones I have seen so far all begin with responses_) which contains a malicious script name in a similar way to employees -382-.js. These have a typical detection rate of 4/56.

Two samples analysed by Malwr [1] [2] show download locations from:

newgeneration2010.it/mkc27f
projectodetalhe.pt/do5j36a


There will be many other download locations too. These drop two different binaries (VirusTotal results [3] [4]). Those two VT results plus these two DeepViz analyses [5] [6] show the malware phoning home to:

138.201.93.46 (Hetzner, Germany)
107.181.187.12 (Total Server Solutions, US)
212.109.219.31 (JSC Server, Russia)
5.152.199.70 (Redstation, UK)


This behaviour is consistent with Locky ransomware.

Recommended blocklist:
138.201.93.46
107.181.187.12
212.109.219.31

Phish: "Please find attached telegraphic transfer copy for payment made to your account today."

At first glance this spam looks like malware, but it appears to be a phish instead:

Attached is a file TT-USD.pdf .. as a rule I would recommend not opening PDF files or other attachments from unknown sources. When you open the file it looks like this:



Yes, it does look that blurry. The enticement here is to click the link in the document, which is something I wouldn't recommend that you do because it could lead to a malicious download, exploit kit or in this case a simple phishing page hosted on poloimport2012.com.



This seems to be phishing for general webmail credentials. Of course, once a hacker has those they can use your account to send spam or even rifle through your private emails and reset passwords and gain access to other important accounts.

Signing in with any credentials appears to fail, but of course the bad guys have just harvested your password..

As I said, I don't recommend opening files like this and clicking links to see where they go. I use a test environment to do this, but some similar spam emails can deliver malware that will silently plant itself on your computer which can be even more dangerous than this phish.

Malware spam: "Weekly report" / "Please find attached the Weekly report."

This fake financial spam comes from random senders and companies and has a malicious attachment:

Hi [redacted],


Please find attached the Weekly report.


King regards,

Castle (A.M.) & Co.
There are a large number of these, with a ZIP file attached containing a malicious scripts with a typical detection rate of 3/56. In this sample Malwr analysis, it downloads a file from:

test.glafuri.net/yxk6s

There will certainly be a LOT of other download locations. The dropped file GSKQtcnNu8MS.exe has a detection rate of 4/55 and that same VirusTotal report indicates C2 traffic to:

138.201.93.46 (Hetzner, Germany)
91.200.14.139 (PP SKS-LUGAN, Ukraine)
104.131.182.103 (Digital Ocean, US)
164.132.40.47 (OVH, France)


Even though other automated analysis failed [1] [2] this time we have previously identified two of those IPs as being Locky ransomware, so there is little doubt that this will be more of the same.

Recommended blocklist:
138.201.93.46

Attached is a ZIP file with a name similar to Invoice 5044-032841.zip which in turn contains a malicious script named in a similar manner to invoice(677454).js which typically has a detection rate of 3/56. Hybrid Analysis of that sample shows the script creating a PFX (personal certificate) file which is then transformed into a PIF (executable) file using the certutil.exe application.

This PIF file itself has a detection rate of 6/56 but automated analysis [1] [2] [3] is inconclusive. The behaviour is somewhat consistent with the Dridex banking trojan but may possibly be Locky ransomware.

In the two samples I have seen, there are attachments named Security Report.zip and Security Notification.zip which in turn contain a Word document with a name such as Security Report ID(11701573).doc

The two documents that I have seen have detection rates of about 3/56 [1] [2] but according to these automated analyses [3] [4] [5] [6] it seems that the infection doesn't work properly, failing to find a created file harakiri.exe. This Malwr report shows a dropped file named harakiri.pfx which isn't an executable, my guess is that this is an encrypted file that hasn't decrypted properly.

UPDATE

According to a third party analysis, this apparently drops Dridex which phones home to:

Evil network: OVH / kaminskiy@radiologist.net

Here's an Angler EK cluster, hosted on multiple ranges rented from OVH France.. working first from this list of Angler IPs in OVH address space we can see a common factor.

5.135.249.214
5.135.249.215
51.255.59.119

91.134.204.243
91.134.204.245
91.134.204.247

One handy thing that OVH does with suballocated ranges is give clear details about the customer. This certainly helps track down abusers. In this case, the ranges these IPs are in are allocated to:

organisation:   ORG-KM91-RIPE
org-name:       Kaminskiy Mark
org-type:       OTHER
address:        Bema 73

That ORG-KM91-RIPE reference can be looked up on the RIPE database: giving more of these little /30 blocks:

5.135.249.212/30
51.255.59.116/30
51.255.59.120/30

91.134.204.248/30
91.134.204.252/30
164.132.223.192/30


OVH have been pretty good at cleaning up this sort of thing lately (unlike PlusServer) so hopefully they will get this under control.

If you want to find other Angler EK ranges then I have a bunch of 'em in my Pastebin.

Malware spam: "Your bank account has been deleted,more information attached. "

This alarming looking spam has a malicious attachment:

Subject:    Account Deleted

Your bank account has been deleted,more information attached. 
I have only seen a single copy of this and the ZIP file attached was corrupt, however, it is very likely that this is a variant of the Locky ransomware run from earlier today.

Malware spam: "Please find attached the file we spoke about yesterday" leads to Locky

Please find attached the file we spoke about yesterday.

Thank you,

PCM, Inc.
Attached is a ZIP file starting with copy_invoice_ and then a random sequence. This contains a malicious script file which in the sample I analysed downloads an obfuscated binary from:

oakidea.com/by2eezw8
islandflavaja.com/0p1nz
dragqueenwig.com/itukabk


Automated analysis of the script [1] [2] shows it dropping a file klA1KMQj2D.exe which has a VirusTotal detection rate of 5/56. Those prior reports plus these additional analyses of the binary [3] [4] [5] show network traffic to:

188.166.168.250 (Digital Ocean, UK)
31.41.44.45 (Relink Ltd, Russia)
92.63.87.53 (MWTV, Latvia)


Those reports all demonstrate clearly that this is Locky ransomware, although the barely encrypted downloaded binaries are a new feature.

Malware spam: "I wanted to follow up with you about your refund. Please find the attached document" leads to Locky

This spam comes from random senders and has a malicious attachment. Here is an example:

From:    Frederic Spears
Date:    20 May 2016 at 10:29
Subject:    Re:

Hi [redacted],

I wanted to follow up with you about your refund.
Please find the attached document

Regards,
Frederic Spears
CBS Corporation

The company name and sender's name varies from message to message. Attached is a ZIP file which contains elements of the recipient's name, which in turn contains one of a variety of malicious scripts. Out of the samples I have seen, I have so far found download locations of:

delicious-doughnuts.net/oqpkvlam
dev.hartis.org/asvfqh2vn
dugoutdad.com/0ygubbvvm
craftbeerventures.nl/hgyf46sx
babamal.com/av2qavqwv
forshawssalads.co.uk/af1fcqav


Only three of those download locations work so far (VirusTotal results [1] [2] [3]) and automated analysis of those [4] [5] [6] [7] [8] shows behaviour consistent with Locky ransomware. All of those reports show the malware phoning home to:

91.219.29.106 (FLP Kochenov Aleksej Vladislavovich / uadomen.com, Ukraine)
51.254.240.89 (Relink LLC, Russia / OVH, France)
138.201.118.102 (Hetzner, Germany)


Recommended blocklist:
91.219.29.106

Malware spam: "Per E-Mail senden: DOC0000329040"

This German-language spam comes with a malicious attachment. It appears to come from the victim themselves, but this is just a simple forgery.

Attached is a ZIP file that matches the reference number in the subject and body text. I have only seen one sample, downloading a binary from:

katyco.net/0uh8nb7

The VirusTotal detection rate is 4/57, the comments in that report indicate that this is Locky ransomware and the C&C servers are at:

188.127.231.124 (SmartApe, Russia)
176.53.21.105 (Radore Veri Merkezi Hizmetleri, Turkey)
217.12.199.151 (ITL, Ukraine)
