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:

From:    Alicia Ramirez
Date:    25 May 2016 at 14:22
Subject:    Weekly report

Hi [redacted],

Please find attached the Weekly report.

King regards,

Alicia Ramirez
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:


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: (Hetzner, Germany) (PP SKS-LUGAN, Ukraine) (Digital Ocean, US) (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.

Malware spam: "Third Reminder - Outstanding Account" leads to Locky

This fake financial spam has a malicious attachment. It comes from random senders. Last week a fake "Second Reminder" spam was sent out.

From:    Ernestine Perkins
Date:    3 May 2016 at 08:54
Subject:    Third Reminder - Outstanding Account

 Dear Client,

We have recently sent you a number of letters to remind you that the balance of $9308.48 was overdue.
For details please check document attached to this mail

We ask again that if you have any queries or are not able to make full payment immediately, please contact us.


Ernestine Perkins
Franchise - Sales Manager / Director - Business Co 

Attached is a ZIP file which in the samples I have seen begins with Scan_ or Document_ each one of which contains four identical copies of the same script, e.g.:

48524088_48524088 - copy (2).js
48524088_48524088 - copy (3).js
48524088_48524088 - copy (4).js
48524088_48524088 - copy.js

Typical detection rates for the scripts seem to be about 3/56.  The samples I have seen download a malicious binary from one of the following locations (there are probably more):


These binaries are all slightly different, with detection rates of 4 to 6 out of 56 [1] [2] [3]. Various automated analyses [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] show that this is Locky ransomware, and it phones home to: (Petersburg Internet Network, Russia) (Hetzner, Germany) (Sobis, Russia) (FLP Kochenov Aleksej Vladislavovich / uadomen.com, Ukraine)

I have only seen a single sample of this, it is likely that the company names and sender will vary. Attached is a file missing_quickbooks982.zip which contains a malicious obfuscated javascript 91610_facture_2016.js which attempts to download a component from:


This drops a file pretending to be favicon.ico which is actually an executable with a detection rate of 3/56. This Hybrid Analysis and this DeepViz report indicate network traffic to: (OrionVM Retail Pty Ltd, Australia) (Hetzner, Germany) (FPT Telecom Company, Vietnam) (EASY Net, Czech Republic)

The payload isn't exactly clear, but it looks like Dridex rather than Locky. Almost certainly one of the two.

Malware spam: "FW: Latest order delivery details" is somewhat rude

This fake financial spam leads to malware:

From:    Milan Bell [Milan.Bell5@viuz-en-sallaz.fr]

Subject:    FW: Latest order delivery details

Good morning!

I kindly ask you to give us a reply finally. We're getting no answers from you. Please stop ignoring invoice requests.

Many thanks and good luck

The rather rude pitch here is a canny bit of social engineering, aimed to make you open the link without clicking. I have only seen one sample of this at present and I guess that the details vary from email to email. In this case the attachment was called pastdue_tovictimdomain.tld340231.zip containing a malicious script pastdue60121342016.js.

This script has a VirusTotal detection rate of just 1/56. The Malwr report and Hybrid Analysis for this show it downloading a malicious binary from:


Cheekily the URL references a well-known security company.  The domain it is using is a hijacked GoDaddy domain, and the download location is actually hosted at: (PE Ivanov Vitaliy Sergeevich / Xserver.ua, Ukraine)

You can be that this is a malicious server and I recommend blocking it. This script downloads a binary named alarm.exe which has a detection rate of 4/56. The Hybrid Analysis for this sample shows network connections to: (OrionVM, Australia) (Hetzner, Germany) (PT Telecom Company, Vietnam) (Datacate , US)

It is not clear what the payload is, but there are indications it is the Dridex banking trojan.

Beerhouse Self Drive
In the only sample I have seen so far, there is an attachment Document No 992958719.doc which has a VirusTotal detection rate of 7/56. The Malwr report for that document shows that it downloads a binary from:


There are probably many other download locations. This dropped file has a detection rate of 6/56. The DeepViz report and Hybrid Analysis between then identify what is likely to be Dridex, phoning home to the following servers: (MultiNet AS, Norway) (Letshost / Digiweb, Ireland) (Contabo GmbH, Germany) (FUFO Studio Agata Grabowska, Poland) (Computers Equipnemt, Bulgaria) (TOV Dream Line Holding, Ukraine) (Topix, Italy) (Impsat, Argentina)

PlusServer has a PlusSized problem with Angler

PlusServer GmbH is a legitimate German hosting company. But unfortunately, the bad guys keep hosting Angler EK sites in their IP ranges over and over again.

So far I have seen many /24 blocks which have effectively been burned by out-of-control Angler (and other EK) infections. There are many individual IPs too, but below I list some of the worst blocks (links go to Pastebin).

Blocking these ranges will block some legitimate sites, but if Angler is causing you a problem then I would lean towards blocking those ranges and accepting the chance of some minor or moderate collateral damage. There are other bad ranges here for other hosts too.

UPDATE 2016-04-25

Here are some more PlusServer ranges where Angler has been rampant:

UPDATE 2016-05-10

Heavy Angler activity has also been spotted in the following ranges:

In addition, some Angler activity has been observed in the following ranges but is not yet widespread (I will update if I see more activity):

PlusServer (or more likely one or more of their resellers) appear to be responsible for a large number of active Angler EK IPs (at a guesstimate, about a quarter). The problem is that some of these ranges are so badly infected (e.g. there are around 48 past and present bad IPs in that the only safe option is to block traffic to those network ranges.

With black hat hosts such as Qhoster or Host Sailor and to some extent Agava you can block the entire network ranges and not block anything of value at all. In using PlusServer, the bad guys can hide their evil sites among legitimate sites where administration might fear to block something accidentally. My personal opinion is that admins need to be bold and block anyway.. it should usually be possible to block individual sites where needed.

Malware spam: "CCE29032016_00034" / "Sent from my iPhone"

The malware spammers have been busy again today. I haven't had time to look at this massive spam run yet, so I am relying on a trusted third party analysis (thank you!)

These spam emails look like the victim is sending them to themselves (but they aren't). Reference numbers vary a little between emails, but the basic pattern is:

From:    victim
To:    victim
Date:    29 March 2016 at 17:50
Subject:    CCE29032016_00034

Sent from my iPhone

Attached is a RAR archive with a name that matches the subject (e.g. CCE29032016_00034.rar) and this contains a malicious .js file that leads to Locky ransomware. My contact tells me that the download locations in the scripts are:


This payload has a detection rate of 4/56. The malware calls back to: (Keyweb, Germany / 300GB.ru, Russia) (OVH, France / Bondhost, Montenegro) (McHost, Russia)

McHost is almost purely a black-hat ISP in my opinion and should be blocked on sight.

To save you putting it into Google Translate, the body text reads "Your message is ready to be sent with the following file or link attached". Attached is a file 9758W-TERREDOC-RS62937-15000.zip which comes in at least eight different versions each containing a different malicious script (VirusTotal results [1] [2] [3] [4] [5] [6] [7] [8]). The Malwr reports for those samples [9] [10] [11] [12] [13] [14] [15] [16] show a malicious binary downloaded from:



Note that the last file is not like the others. There may be other download locations. The "765f46vb" binary has a detection rate of 4/57 and according to all those previous reports plus these other automated analyses [17] [18] [19] [20] the malware phones home to: (Park-web Ltd, Russia) (300GB.ru, Russia / Keyweb, Germany) (Host Sailor, Netherlands) (SKS-Lugan, Ukraine) (MWTV, Latvia) (OVH, Germany / Unihost, SC)

All of those look like pretty shady neigbourhoods, although I haven't examined them closely at this point. The payload is the Locky ransomware.

The other binary appears to be another version of Locky which appears to phone home to the same servers.

Details on the individual emails vary. Attached is a ZIP file which contains one of a variety of malicious scripts (sample VirusTotal results [1] [2] [3] [4]). According to these Malwr reports [5] [6] [7] these scripts attempt to download a malicious binary from the following locations:


These sites are hosted on: (Province of British Columbia, Canada) (Netmarlis Hosting, Turkey) (Sadecehosting, Turkey) (WZ Communications, US) (Martin Andrino Ltd, Netherlands)

This Malwr report and this Hybrid Analysis shows communications with: (PE Astakhov Pavel Viktorovich, Ukraine) (EDIS, Italy) (EDIS, Netherlands) (EDIS, Spain) (PS Internet Company LLC, Kazakhstan) (Leaseweb, Germany)

The two executables seem different (VirusTotal results [1] [2]). It looks like it might be dropping both ransomware (Teslacrypt perhaps) and Dridex (banking trojan) alternately.

These domains are also associated with some of the IPs. Consider them all to be evil:

Please see attached letter and a copy of the original invoice.
Attached is a file with a semirandomly name, e.g. RG026052317614-SIG.zip which contains a malicious script. This script then downloads an executable from the same locations as found here, dropping a malicious executable with a detection rate of 10/55 (changed from earlier today).

Third party analysis (thank you) indicates that this then phones home to the following locations: (OVH, France)
(Dmitry Melnik, Ukraine / Myidealhost.com aka Hetzner, Germany) (Virty.io, Russia)

The payload is the Locky ransomware.

This fake financial spam comes from random senders, the attachment is malicious and drops the Locky ransomware:

Attached is a file with a semirandom name similar to invoice_feb-92031923.doc (Sample VirusTotal report) which contains XML that looks like this [pastebin]. Malwr analysis of these samples [1] [2] shows it downloading a malicious executable from:


If recent patterns are followed, there will be several different download locations with different versions of the file at each. I will let you know if I get these locations. The binaries has a detection rate of 7/55 and 6/54 and these Malwr reports [1] [2] [3] indicate that it phones home to: (PlusServer AG, Germany) (Relink Ltd, Russia)

Other samples are being analysed, but in the meantime I recommend that you block traffic to:


Some additional download locations from these Malwr reports [1] [2] [3]:


..stil working on those other locations!


Two other locations are revealed in these Malwr reports [1] [2]:
