Malware spam: "Your order #7738326 From The Safety Supply Company" / Orders - TSSC [Orders@thesafetysupplycompany.co.uk]

This fake financial spam does not come from The Safety Supply Company but is instead a simple forgery with a malicious attachment:
From:    Orders - TSSC [Orders@thesafetysupplycompany.co.uk]
Date:    15 January 2016 at 09:06
Subject:    Your order #7738326 From The Safety Supply Company

Dear Customerl

Thank you for your recent purchase.

Please find the details of your order through The Safety Supply Company attached to this email.

Regards,

The Sales Team
So far I have seen just a single sample, with an attachment Order.doc which has a VirusTotal detection rate of 4/55. Analysis of this document is pending, however it is likely to be the Dridex banking trojan.

UPDATE 1

This Hybrid Analysis on the first sample shows it downloading from:

149.156.208.41/~s159928/786585d/08g7g6r56r.exe

That download IP belongs to Academic Computer Centre CYFRONET AGH, Poland. This executable also seems to commicate with:

216.117.130.191 (Advanced Internet Technologies Inc., US)
41.38.18.230 (TE Data, Egypt)
5.9.37.137 (Hetzner, Germany)


I have now seen another version of the DOC file [VT 4/54] which has similar characteristics.

Dropped file MD5:
9138e36d70ab94349558c61e92ab9ae2

985bb69a8c292d90a5bd51b3dbec76ac


UPDATE 2

This related spam run gives some additional download locations:

nasha-pasika.lviv.ua/786585d/08g7g6r56r.exe
arm.tv/786585d/08g7g6r56r.exe


Sources also tell me that there is one at:

Malware spam: "Message from local network scanner" / Scann16011310150.docf

This fake document scan comes with a malicious attachment.
From:    jpaoscanner@victimdomain.tld
Date:    14 January 2016 at 10:45
Subject:    Message from local network scanner
There is no body text, and the email appears to come from within the victim's own domain, but this is just a simple forgery.

Attached is a file Scann16011310150.docf which comes in at least five different versions (VirusTotal results [1] [2] [3] [4] [5]). The file is a Word document, despite the extension.. I don't think anything opens DOCF files by default. This is maybe an error, or perhaps some sort of social engineering, or perhaps simply a way to bypass security filters.

Analysis of these documents is pending (check back later), however this is likely to be the Dridex banking trojan. Please check back.

UPDATE 1

Analysis is running slowing this morning, however this Hybrid Analysis shows one of the samples in action, downloading a binary from:

www.willsweb.talktalk.net/786h5g4/9787g4fr4.exe

This has a detection rate of 3/55. That same analysis reports that it phones home to:

188.138.88.14 (PlusServer AG, France)

I strongly recommend that you block traffic to that IP.

UPDATE 2

These two Malwr reports [1] [2] reveal some additional download locations:

www.gooutsidethebox.net/786h5g4/9787g4fr4.exe
199.59.58.162/~admin1/786h5g4/9787g4fr4.exe

Evil network: 46.30.40.0/21 / Eurobyte LLC and GoDaddy

Recently I kept coming across the name "Eurobyte LLC" when it came to hosting malware [1] [2] to an extent that I became rather suspicious about this Russian hosting company and what it is they actually do.

From looking around, it seemed that whoever Eurobyte rented servers to had an unhealthy interest in CryptoWall and the Angler EK. Eurobyte is a Russian hosting company, which in turn is a customer of Webzilla in the Netherlands. One of Webzilla's other customers is McHost.ru who also have a shitty reputation.

A look at Webzilla's AS35415 range shows that Eurobyte LLC is allocated the following blocks:

46.30.40.0/24
46.30.41.0/24
46.30.42.0/24
46.30.43.0/24
46.30.44.0/24
46.30.45.0/24
46.30.46.0/24
46.30.47.0/24

These coincide with a large-ish block of 46.30.40.0/21 which contains all the Eurobyte /24s.

Using DNSDB I found over 70,000 sites associated with this block. By associated I mean site currently hosted in the /21, or hosted there in the past few years. Crucially, that includes a lot of somedomains, nameservers and that sort of thing. In order to keep things manageable, I consolidated almost all the subdomains down into their main domains, leaving 18,260 domains and sites.

The next step was to take that data and look up the current IPs and Google prognosis (results here), giving 4048 sites with their main domains currently hosted at Eurobyte. Of this, only the following 16 appear to be malicious, 0.4% of the total.

promodoms.ru
androiddeff.ru
xpopkax.ru
xxxplayx.ru
justyoutube.ru
maineaquaventus.info
dallasdispute.com
waysecureforyou.pw
mammals.ru
101curtesty.pw
hitbambar.pw
topgradations.pw
getgradations.us
igrakon.biz
alwrgame.ru
igrakon-loads.ru

0.4% is a tiny amount.. I would typically expect to see about 1-2% on any network. So, Eurobyte LLC looks squeaky clean, yes?

In fact, this low number of malicious sites is misleading. If we go back to the original 18,260 domains and look at the number of malicious domains there, the total is 3,129. That's 17.1% of the original dataset.. a very high figure indeed.

The discrepancy appears to exist because there are thousands of subdomains hosted in the 46.30.40.0/21 range, where the main domain (e.g. www.) is hosted in a completely different location. The subdomains are then used to host malware such as the Angler Exploit Kit, while leaving the main domain completely untouched. The attack is known sometimes as domain shadowing.

Out of the malicious sites, 2793 are currently hosted at GoDaddy. That's 89.2% of the sites listed as malicious. But it turns out, that out of the other 336 sites taggest as malicious, about 300 are either registered with GoDaddy but hosted elsewhere, or use GoDaddy name servers. In other words, approximately 99% of the malicious sites belong to someone with a GoDaddy account.

But in fact, it is even worse than that. Looking at the domains that aren't tagged as malicious by Google reveals hundreds more similar hijacked GoDaddy domains. This list contains 5201 domains that are both parked on GoDaddy servers and have had malicious subdomains running in the Eurobyte LLC IP range. There are probably hundreds more that are hosted elsewhere.

What appears to be going on here is a domain shadowing attack on a massive scale, primarily leading victims to exploit kits.

There do appear to be some genuine Russian-language sites hosted in this block. But if you don't tend to send visitors to Russian sites, I would very strongly recommend blocking 46.30.40.0/21 from your network.

If you are a GoDaddy customer then enabling-two factor authentication might give you some additional protection against this type of attack.

While researching this topic, I discovered that Talos had done some similar work which also pointed a finger at Eurobyte and their very lax control over their network.

There are at least five different versions of the attachment 033777 [Ref. MARKETHILL CHURCH].doc (VirusTotal results [1] [2] [3] [4] [5]). Analysis of these documents is pending, however it is likely to be the Dridex banking trojan.

This binary has a detection rate of 4/53. The Hybrid Analysis shows the malware phoning home to:

I recommend that you block traffic to that IP.

So far I have seen just one sample of this spam, and it was malformed so it was not possible to open the attachment without decoding it first. When done, this gave a file FILENAME.DOC with a detection rate of 3/54. The Malwr report for the document is inconclusive, but it most likely attempts to load the Dridex banking trojan.

The attached file is named ScannedDocs122151.xls which comes in at least five different versions (VirusTotal results [1] [2] [3] [4] [5]). The Malwr reports for these documents [6] [7] [8] [9] [10] show the malicious macro contained within downloading a malware executable from:

This dropped binary has a detection rate of 4/55. It is unclear what this does as in the Malwr report it throws an error. The payload is almost definitely the Dridex banking trojan, and even if this version is faulty then it is likely that the malware will be fixed shortly.

The sender's name, references and attachments may vary. This appears to be a spam from Dridex 120, and it is a characteristic that there is a very large number of variants of the attachments. In this case, I analysed three different attachments with detection rate of about 2/55 [1] [2] [3] and which according to these Malwr reports [4] [5] [6], downloads a binary from the following locations:

5.189.216.10/montana/login.php
77.246.159.154/montana/login.php

A binary named trap.exe with an MD5 of aab74722020e631147836fc009f9419d and a detection rate of 5/54 is downloaded. According to this Malwr report the executable phones home to:

Malware spam: "E-Service (Europe) Ltd Invoice No: 10013405" / "Andrew Williams [andrew.williams@eurocoin.co.uk]"

This fake financial spam does not come from E-Service (Europe) Ltd but is instead a simple forgery with a malicious attachment:

E-Service have been exceptionally quick about posting an update on their Twitter page. However, they have not been hacked at all as it is trivially easy to forge an email message. The attachment is a malicious Excel spreadsheet which leads to the Dridex banking trojan.

So far, I have seen five different versions of the attachment, all named Invoice 10013405.XLS and with detection rates of about 8/55 [1] [2] [3] [4] [5]. Analysis of the attachments is pending, please check back later.

UPDATE

The Malwr reports for the attachment [1] [2] [3] [4] [5] show that the macro in the spreadsheet downloads a file from the following locations:

arellano.biz/5fgbn/7tfr6kj.exe
pastorsschoolinternational.org/5fgbn/7tfr6kj.exe
www.c0-qadevtest.net/5fgbn/7tfr6kj.exe


This dropped file has a detection rate of 1/55. It is the same binary as found in this earlier spam run which phones home to:

114.215.108.157 (Aliyun Computing Co, China)

This is an IP that I strongly recommend blocking.

Dropped file MD5:
3d59b913f823314ca85839b60a9d563a

Malware spam: "Your latest invoice from UKFast No.1228407" / UKFast Accounts [accounts@ukfast.co.uk]

This fake financial spam does not come from UKFast but is instead a simple forgery with a malicious attachment.
From     UKFast Accounts [accounts@ukfast.co.uk]
Date     Mon, 11 Jan 2016 11:00:10 +0300
Subject     Your latest invoice from UKFast No.1228407
I am unable to determine what the body text is at the moment. In this case, the attachment was named Invoice-1228407.doc and has a VirusTotal detection rate of 3/54. The Malwr report shows that the malicious macro [pastebin] downloads an executable from:

www.vmodal.mx/5fgbn/7tfr6kj.exe

This binary has a detection rate of 2/54 and an MD5 of 3d59b913f823314ca85839b60a9d563a.  This Malwr report for the dropped file indicates network traffic to:

114.215.108.157 (Aliyun Computing Co, China)

I strongly recommend that you block traffic to that IP. The payload is the Dridex banking trojan.

Malware spam: "Invoice from DSV 723A36B7 , ARIA (U K) LTD, 04995672, Customer ref: ALEX MUNRO, SE/GB"

I have only seen a single sample of this email at present, but if consistent with other similar emails then details such as the sender's name and reference numbers will vary. In this case, the attachment was named INV-SE723A36B7.doc and had a VirusTotal detection rate of 1/55.

According to this Malwr report, the sample attempts to download a further component:

194.28.84.79/softparade/spanish.php

There will most likely be a couple of other download locations too (check back later for more). This IP address belongs to Hostpro in Ukraine. Those other locations are likely to be in Ukraine too.

A file named hram.exe is dropped onto to target system with a detection rate of 4/54. The Malwr report indicates that this communicates with:

78.47.119.93 (Hetzner, Germany)

This is a critical IP to block, as we also saw it in use yesterday. The payload is most likely the Dridex banking trojan.

UPDATE 1

A contact (thank you) let me know of two other download locations:

176.103.62.14/softparade/spanish.php
51.254.51.178/softparade/spanish.php


These are:

176.103.62.14 (PE Ivanov Vitaliy Sergeevich, Ukraine)
51.254.51.178 (OVH, France / Dmitry Shestakov, Russia)

Both those are pretty well-known providers of malware.  I recommend that you block the entire /20 in the first instance and the blocks referenced here in the second.

MD5s:
5ab2a67268b3362802a13594edafbd2e
7d60996dd9293df5eecd07f33207aca8


Recommended blocklist:
78.47.119.93
194.28.84.79
176.103.48.0/20
51.254.51.176/30


UPDATE 2

An updated version of the payload is currently being spammed out as on 11.01.16, with a payload identical to this spam run.

The sernder's name will vary, as will the attachment name. I have only seen a single sample at the moment with a detection rate of 2/54. Functionally, the payload is identical to that found in this earlier spam run, and it drops the Dridex banking trojan.

Malware spam: "Invoice 01147665 19/12 £4024.80" / "Ibstock Group"

This fake financial spam is not from the Ibstock Group but instead contains a malicious attachment. It is closely related to this spam which was sent out earlier today.

Hi,

Happy New Year to you !

Hope you had a lovely break.

Many thanks for the payment. There’s just one invoice that hasn’t been paid and doesn’t seem to have a query against it either.

Its invoice  01147665  19/12  £4024.80  P/O ETCPO 35094

Can you have a look at it for me please?

Thank-you !

Kind regards

The sender's name varies, as does the reference number which matches the name of the attachment. I have seen three unique samples so far (there are probably more) with VirusTotal detection rates of 2/54 [1] [2] [3] and the Malwr reports [4] [5] [6] show these documents communicating with:

193.201.227.12/ideal/jenny.php
91.223.88.205/ideal/jenny.php
176.103.62.108/ideal/jenny.php


IPs are allocated to:

176.103.62.108 (Ivanov Vitaliy Sergeevich, Ukraine)
91.223.88.205 (Private Person Anton Malyi, Ukraine)
193.201.227.12 (PE Tetyana Mysyk, Ukraine)


As before, a binary geroin.exe is dropped which communicates with:

78.47.119.93 (Hetzner, Germany)

The payload is the Dridex banking trojan. The recommended blocklist and sample MD5s can be found in this post.
