Malware spam spoofing "Hillsong Church London"

This rather confused spam comes with a subject saying one thing.. for example:

GREKA ENGINEERING & TECHNOLOGY LTD March Invoice #2875
LIMITLESS EARTH PLC March Invoice #75913
FALKLAND ISLANDS HLDGS March Invoice #58093
MULTI UNITS FRANCE March Invoice #6689
SHORE CAPITAL GROUP LTD March Invoice #1612

But the body text is from a church..

Hi there,

Please find the remittance advice for the payment made on the 19th Feb 2015 from
Hillsong Church London.

Please let me know if there are any queries.

Hillsong Church London
www.hillsong.co.uk http://www.hillsong.co.uk

Attached is either an Excel spreadsheet named in a style similar to Hillsong-C2E24.xls (VT results [1] [2] [3]) or a ZIP file with a similar name to Hillchurch-03234D.zip containing a script TR7433029032016.js or TR913740032016.js (VT results [4] [5]).

The Malwr reports are a mixed bunch with only the first three giving any data [1] [2] [3] [4] [5] showing download locations at:

oimedoaeklmrf.giftcardnanny.ca/nu2o3mk4/c987ah8j9ei1.php
eiadmeodeda.securalive.ca/8fjvimkel1/c987ah8j9ei1.php
doaemdpmekd.securalive.eu/8fjvimkel1/c987ah8j9ei1.php

In fact, all these locations are on the same server (and are the same binary), hosted on:

193.201.227.90 (PE Tetyana Mysyk, Ukraine)

According to VirusTotal, there are a few hijacked GoDaddy subdomains on that IP. This method is a little unusual for this type of attack.

Those Malwr reports and this Hybrid Analysis show the malware phoning home to:

24.172.94.181 (Time Warner Cable, US)

It isn't entirely clear what the payload is, but it is probably Dridex or possibly some form of ransomware.

I received only two samples (VT [1] [2]) of which only one worked in Malwr (this is the other). However, third-party analysis (thank you) shows download locations at:

cabanasestina.ro/num/5buybbtyu8

Each location has a different binary (VT [1] [2] [3] [4] [5] [6]) which between them phone home to the following IPs:

95.213.184.10 (Selectel, Russia)
192.71.213.69 (EDIS, Spain)
217.172.182.99 (PlusServer, Germany)

Malware spam: "ZYL Invoice" / "Outstanding Invoice" / "Sales Invoice"

These randomly-generated financial spam emails come with a malicious attachment:

From:    Buckminster U. Petty
Date:    2 March 2016 at 07:55
Subject:    Outstanding Invoice

Please check the receipt attached to this message. The Transaction will be posted on your account within 48 hours.

Please find the payment details attached to this message. The Transfer should appear on your account in 2 days.

From:    Audrey U. Oneil
Date:    2 March 2016 at 07:34
Subject:    Re: Sales Invoice

Please review the invoice attached to this message. The Transfer should appear on your bank in 48 hours.

Attached is a randomly-named file with an RTF extension which is actually a DOCX file in disguise. I have seen three different attachments with detection rates of 1/55 [1] [2] [3] and the Malwr reports for those [4] [5] [6] show the macro contained within downloading from the following locations:

thevillagelounge.nl/e.jpg?LnRiNLIoPC3=55
creeko.com/d.jpg?GIk1nRWM0r27m5Ss=50
creeko.com/d.jpg?GIk1nRWM0r27m5Ss=8

The VirusTotal results for the two unique binaries dropped are 3/55 [1] [2] but automated analysis [3] [4] is inconclusive. It looks rather like ransomware, but I cannot confirm this.

Malware spam: "Emailing: MX62EDO 01.03.2016"

I have seen two samples so far, with an attachment that has a similar name to MX62EDO20160301538482.zip which contains a malicious randomly-named script (e.g. PK5293425659.js). Detection rates on the scripts are fairly low [1] [2]. According to these Malwr reports [3] [4] the payload is the Locky ransomware. These two samples download malicious binaries from:

tianshilive.ru/vqmod/xml/87yhb54cdfy.exe
ubermensch.altervista.org/system/logs/87yhb54cdfy.exe

In turn, these attempt to phone home to:

31.184.197.119/main.php
5.34.183.195/main.php

These are the same C&C servers as seen here.

Malware spam: "Dear ValuedCustomer, It is very unpleasant to hear about the delay with your order"

sure that your purchase will be delivered in time and we alsoguarantee that you will
be satisfied with our services.

Thank you for your business with our company.

Stefanie Sullivan

All the samples I have seen have slightly mangled headers. The sender name varies. Attacked is a ZIP file named in a similar format to order_copy_7B6B7E08.zip which contains a malicious script named something like:

important_181031694.js
warning_659701636.js
statistics_466026824.js

I have seen six different samples so far with zero detection rates [1] [2] [3] [4] [5] [6] and which according to these analysis [7] [8] [9] [10] [11] [12] attempt to download a Locky binary from:

sitemar.ro/5/92buyv5
pacificgiftcards.com/3/67t54cetvy
maisespanhol.com.br/1/8y7h8bv6f

Those binaries phone home to:

5.34.183.195/main.php
31.184.197.119/main.php

Those C&C servers are the same as I mentioned in this spam run and I suggest you block traffic to:

5.34.183.195
31.184.197.119
51.254.19.227

Hi,

So far I have seen just one sample of this, so it is possible that other companies are being spoofed as well. Attached is a file INV09BEE9.zip which in turn contains a malicious script statistics_60165140386.js. This has a detection rate of precisely zero.

This Malwr report shows that it is the Locky ransomware, download a binary from:

intuit.bitdefenderdistributor.info/intrabmw/get.php

This is hosted on a bad webserver at..

93.95.100.141 (Mediasoft ekspert, Russia)

..and it then phones home to..

5.34.183.195 (ITL / UA Servers, Ukraine)

There are probably other download locations. My contacts tell me that these are C2 servers for an earlier German-language campaign, it is possible they are being used here. Block 'em anyway..

31.184.197.119 (Petersburg Internet Network ltd., Russia)
51.254.19.227 (Dmitrii Podelko, Russia / OVH, France)

Date:    29 February 2016 at 19:05
Subject:    Scanned image

Image data in PDF format has been attached to this email.

The email appears to originate from within the victim's own domain. Attached is a randomly-named file with a format similar to 2016022936833473.zip containing a malicious script with a name somewhat like SCAN000469497.js  I have seen three different versions of the attached scripts with detection rates of around 1/55 [1] [2] [3]. The Malwr reports for those [4] [5] [6] show download locations at:

www.notebooktable.ru/system/logs/7ygvtyvb7niim.exe
svetluchok.com.ua/admin/images/7ygvtyvb7niim.exe [404]
mansolution.in.th/system/logs/7ygvtyvb7niim.exe

This appears to be Locky ransomware with a detection rate of just 3/55. Those Malwr reports also indicate C&C servers at:

51.254.19.227 (Dmitrii Podelko, Russia / OVH, France)
185.14.29.188 (ITL aka UA Servers, Ukraine)

Note that one of the download locations is 404ing. There may be other download locations that I am not aware of, howerver I recommend that you block all traffic to:

51.254.19.227
185.14.29.188

Malware spam: "Invoice #16051052/15" / "Dear costumer"

From:    Velma hodson
Date:    29 February 2016 at 16:49
Subject:    Invoice #16051052/15

Dear costumer,

You are receiving this informational letter because of the fact that you have a debt totaling $157,54 due to late payment of invoices dating March ‘15.

In attachment you will find a reconciliation of the past 12 months (year 2015).

Please study the file and contact us immediately to learn what steps you should take to avoid the accrual of penalties.

I have only seen a single sample with an attachment named Invoice_ref-16051052.zip which in turn contains a malicious script invoice_kOUEsX.js that looks like this [pastebin]. The script has a VirusTotal detection rate of 2/55 and these automated analysis tools [1] [2] show that it attempts to download a binary from the following locations:

ohiyoungbuyff.com/69.exe?1
helloyungmenqq.com/69.exe?1

The domain names have a similar theme, indicating that the servers are malicious. It migh be worth blocking:

91.196.50.241 (EuroNet, Poland)
50.3.16.250 (Eonix, US)

This Malwr report  shows that the dropped payload is ransomware, calling home to the following domains:

biocarbon.com.ec
imagescroll.com
music.mbsaeger.com
stacon.eu

I recommend that you block traffic to those domains plus the two IPs, giving a recommended blocklist of:

91.196.50.241
50.3.16.250
biocarbon.com.ec
imagescroll.com

I have seen only one sample of this with an attachment named Order ref. 16173.xls  which has a VirusTotal detection rate of 6/55. This Malwr report plus this Hybrid Analysis for that sample shows a binary being downloaded from:

thetoyshop.by/system/logs/76tg654viun76b

There are probably other download locations too. This dropped file has a detection rate of 3/52. Those two reports indicate that this is the Dridex banking trojan. It phones home to:

203.162.141.13 (VietNam Data Communication Company, Vietnam)

I strongly recommend that you block traffic to that IP.

Evil networks to block 2016-02-26

These networks are clusters of the Angler EK and other badness. I tend to Tweet about Angler IPs rather than blog about them. Following the #AnglerEK hashtag at Twitter can yield more information, often in realtime.

All the links go to Pastebin with more information about the IPs and the blocks. Note that a few of these blocks do contain some legitimate Russian-language sites, but if your users don't visit that sort of site then you should be OK to block them.

I strongly recommend that you block traffic to that IP.

Evil network: 184.154.28.72/29 (Marko Cipovic / Singlehop) and liveadexchanger.com

liveadexchanger.com is an advertising network with a questionable reputation currently hosted on a Google IP of 146.148.46.20. The WHOIS details are anonymous, never a good sign for an ad network.

Seemingly running ads on the scummiest websites, liveadexchanger.com does things like trying to install fake Flash updates on visitors computers, as can be seen from this URLquery report... you might find the screenshot missing because of the complex URL, so here it is..

That landing page is on alwaysnewsoft.traffic-portal.net (part of an extraordinarily nasty network at 184.154.28.72/29) which then forwards unsuspecting visitors to a fake download at intva31.peripheraltest.info  which you will not be surprised to learn is hosted at the adware-pusher's faviourite host of Amazon AWS.

Of the 567 sites that have been hosted in this /29 (not all are there now), 378 of them are tagged as malicious in some way by Google (67%) and 157 (28%) are also tagged by SURBL as being malicious in some way. Overall then, 74% are marked as malicious by either Google or SURBL, which typically means that they just haven't caught up yet with the other bad domains. The raw data can be seen here [pastebin].

In the only sample I have seen before, there is an attached file named archive-0910001923884.docm which has a VirusTotal detection rate of 3/52. Analysis of this document is pending, but it is likely to drop either the Dridex banking trojan or Locky ransomware.

UPDATE 1

The Hybrid Analysis of the document plus the VirusTotal scan of the dropped EXE look like Dridex. The download location for that document was:

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:

91.121.97.170/main.php (OVH, France)
46.4.239.76/main.php (Dmitry Melnik, Ukraine / Myidealhost.com aka Hetzner, Germany)

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:

ratgeber-beziehung.de/5/5.exe
www.proteusnet.it/6/6.exe

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:

85.25.138.187 (PlusServer AG, Germany)
31.41.47.3 (Relink Ltd, Russia)

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

85.25.138.187
31.41.47.3

UPDATE 1

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

Attached is a file with a format similar to RG460634280127-SIG.zip which contains a malicious javascript in the format RG6459762168-SIG.js or similar. At the moment, I have seen two samples, both with zero detection rates at VirusTotal [1] [2]. Malwr analysis of one of the samples shows that a binary is downloaded from:

mondero.ru/system/logs/56y4g45gh45h

Other samples probably have different download locations. This executable has a detection rate of 7/53 and it appears to drop another executable with a relatively high detection rate of 26/55. Both the VirusTotal and Malwr reports indicate that this is the Locky ransomware from the people who usually push Dridex.

The malware phones home to:

46.4.239.76 (Dmitry Melnik, Ukraine / Myidealhost.com aka Hetzner, Germany)

But in fact the entire 46.4.239.64/27 range looks pretty bad and I recommend that you block it.

Incidentally, full credit to the company involved in putting this massive banner on their website warning people about the fake email..

An additional analysis from a trusted source (thank you). Download locations are:

My name is yvon, am the personnel manager of a large UK company.

If you are interested in our offer, mail to us your answer on resume@gbjobsite.com and we will send you an extensive information as soon as possible.

The spam appears to originate from within the sender's own domain, but this is just a simple forgery. Emails sent to the domain gbjobsite.com are sent to an innocuous-looking but nonetheless evil IP of 172.246.47.65 (Enzu Inc, US). Nameservers are using the domain abcdns.biz. Domain registration details are either fake or anonymous.

The nature of the job is illegal, and will most likely involve money laundering, handling stolen goods or other fraudulent activities. Avoid at all costs.

Hello,

I'm looking for someone who can handle my business & personal errands at his/her spare time as I keep traveling a lot. Someone who can offer me these

services mentioned below:

* Mail services (Receive my mails and drop them off at UPS or USPS)
* Shop for Gifts
* Bill payment (pay my bills on my behalf, access to the funds would be provided by me)
* Sit for delivery (at your home) or pick items up at nearby post office at your convenience.

Let me know if you will be able to offer me any or all of these services and 10% of my income weekly would be your weekly payment. If you will be available for this job position ,send me a confirmation e-mail and send me your details like complete name/address/country/state/ city/zip/phone or you could even attach your resume.I do have a pile up of work and a number of unattended duties which you can assist me with soon.

Please note that this job DOES NOT require any financial obligation of any sort from you as I would be catering for all expenses.

I look forward to hearing from you.

Sincerely,

Mr.Walter.Smith.

It appears to come from the domain ema.su (".su" is the old domain for the Soviet Union, still around today) but in face the Reply-To address is waltersmith7@ig.com.br. The email was routed through an insecure server at 50.47.43.21 (mail.plantsmartsales.com) and apparently originated from 71.2.1.212 (apparently in Warren, Ohio).

Despite appearing to be a "no risk" proposition with a 10% payoff, all the money being handled is actually stolen, and the person handling it will be liable for 100% of the loss and could face legal action. Any goods handled and reshipped will be stolen, and any correspondence sent and received will be fraudulent. Avoid this at all costs.

I have seen two variants of the document (VirusTotal [1] [2]). Analysis of the documents is pending, however it is likely to be the Dridex banking trojan.

UPDATE 1

There is a second variant of the spam with essentially the same (undefined) payload:

From:    Heather Ewing
Date:    18 February 2016 at 08:41
Subject:    Invoice

Dear Sir/Madam,

I trust this email finds you well,

Please see attached file regarding clients recent bill. Should you need further assistances lease feel free to email us.

Best Regards,

The Bank of New York Mellon Corporation www.bnymellon.com

In this case the attachment was named Invoice51633050.doc - automated analysis is inconclusive. An examination of the XML attachment [pastebin] indicates that it may be malformed.

UPDATE 2

A contact (thank you) analysed one of the samples and found that the document downloaded an executable from:

killerjeff.free.fr/2/2.exe

According to this Malwr report this is the Locky ransomware, and it phones home to:

95.181.171.58 (QWARTA LLC, Russia)
69.195.129.70 (Joes Data Center, US)

I suspect that the second one may be a sinkhole, but there should be no ill effects from blocking it.


UPDATE 3

A couple more samples have come to light [1] [2] one of which shows a new phone home location of:

185.14.30.97 (ITL Serverius, NL)

UPDATE 4

From user Ralf9000 at VirusTotal here are some more download locations:

uponor.otistores.com/3/3.exe
premium34.tmweb.ru/4/4.exe
bebikiask.bc00.info/5/5.exe
avp-mech.ru/7/7.exe

6.exe seems to be missing. Analysis of these is pending.

UPDATE 5

According to these Malwr reports on all the available samples [1] [2] [3] [4] [5] [6] the various versions of Locky seem to call back to:


95.181.171.58 (QWARTA LLC, Russia)
31.41.47.37 (Relink Ltd, Russia)
185.14.30.97 (ITL, Ukraine / Serverius, Netherlands)

In the sample I saw, the attachment was named 19875_Rechnung_2016-11365_20160215.docm and has a VirusTotal detection rate of 5/54.

According to this Malwr report  the binary attempts to download the Locky ransomware (seemingly a product of those behind the Dridex banking trojan). It attempts to download a binary from:

feestineendoos.nl/system/logs/7623dh3f.exe?.7055475

This dropped file has a detection rate of 3/53.  Analysis of the file is pending, but overall this has been made more complicated because the Locky installer calls out to a number of domains, many of which actually appear to have been sinkholed.

Machines infected with Locky will display a message similar to this:

Unfortunately, the only known way to recover from this is to restore files from offline backup once the infection has been removed from the PC.

UPDATE

Another version plopped into my inbox, VT 7/54  and according to this Malwr report, it downloads from:

nadeenk.sa/system/logs/7623dh3f.exe?.7055475

This variant POSTs to a server at:

46.4.239.76 (Myidealhost.com  / Hetzner, Germany)

It is likely that the C2 server (identified in the previous report) is:

85.25.149.246 (PlusServer AG, Germany)

Malware spam: Fwd:Accumsan Neque LLC Updated Invoice / Please turn on the Edit mode and Macroses!

This malware spam may come from several different companies, but I have only a single sample. It is notable for the mis-spelling of "Macros" as "Macroses" in the document.

From:    Fletcher Oliver [angel@jiahuan.com.tw]
Date:    17 February 2016 at 06:23
Subject:    Fwd:Accumsan Neque LLC Updated Invoice

Good morning

Please check the bill in attachment. In order to avoid fine  you have to pay in 12 hours.

Best regards

Fletcher Oliver
Accumsan Neque LLC

Attached is a document Q7FX9ZH.doc with the distinctive text Attention! To view this document, please turn on the Edit mode and Macroses!

Needless to say, enabling Edit mode and Macroses is a Very Bad Idea. The VirusTotal detection rate for this file is just 2/54. Hybrid Analysis [1] [2] shows that the macro first downloads from:

www.design-i-do.com/mgs.jpg?OOUxs4smZLQtUBK=54

This looks to be an unremarkable JPEG file..

(Note that I have munged the JPEG slightly to stop virus scanners triggering). As far as I can tell, the JPEG actually contains data that is decrypted by the macro (a technique called steganography). A malicious VBS is created [pastebin] and a malicious EXE file is dropped with a VirusTotal result of 7/54.

Automated analysis of the dropped binary [1] [2] shows that it phones home to:

216.59.16.25 (Immedion LLC, US / VirtuaServer Informica Ltda, Brazil)

I strongly recommend that you block traffic to that IP. Payload is uncertain, but possibly the Dridex banking trojan.
