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.

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]:

ecoledecorroy.be/1/1.exe

Any unauthorised copying, disclosure or distribution of the material in this e-mail is strictly forbidden.

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..

UPDATE

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

mondero.ru/system/logs/56y4g45gh45h

Fake job: resume@gbjobsite.com

This fake job offer looks like it might be from the creators of the Dridex banking trojan. It comes with various subjects:

Cooperation with the great company
We offer new vacancy
employees needed
cooperation with an international company
hi!
The crisis has finished! Work with us!
beneficial offer
Wanted regional manageres
Hello!
partial occupation
Working with partial occupancy

The part-time employment

The body text is always very similar:

Hello!

We are looking for employees working remotely.

My name is yvon, am the personnel manager of a large UK company.
Most of the work you can do from home, that is, at a distance.
Salary is 1000£ - 4000£.

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.
Best regards!
Personal Staff 

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.

Fake job: "Personal Assitant and Administrative officer needed." / Walter.Smith [sales@ema.su]

This job offer is a fake, and is actually intended to recruit people for criminal activities such as money laundering or receiving stolen goods.

Reply-To:    waltersmith7@ig.com.br

Subject:    Re: Personal Assitant and Administrative officer needed.

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,

Heather Ewing
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:

onigirigohan.web.fc2.com/1/1.exe
killerjeff.free.fr/2/2.exe
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)

Recommended blocklist:
85.25.149.246
46.4.239.76

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]

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.

Malware spam: ATTN: Invoice J-06593788 from random companies

This fake financial spam does not come from Apache Corporation but instead is a simple forgery with a malicious attachment.

From:    June Rojas [RojasJune95@myfairpoint.net]
Date:    16 February 2016 at 09:34
Subject:    ATTN: Invoice J-06593788

Dear nhardy,

Please see the attached invoice (Microsoft Word Document) and remit payment according to the terms listed at the bottom of the invoice.

Let us know if you have any questions.

We greatly appreciate your business!

June Rojas
Apache Corporation      www.apachecorp.com

Other versions of this spam may come from other corporations. In the single sample I have seen there is an attached file invoice_J-06593788.doc which has a VirusTotal detection rate of 5/54. Analysis is pending, however this is likely to be the Dridex banking trojan.

UPDATE 1

This Dridex run exhibits a change in behaviour from previous ones. I acquired three samples of the spam run and ran the Hybrid Analysis report on them [1] [2] [3] and it shows that the macro dowloads from one of the following locations:

www.southlife.church/34gf5y/r34f3345g.exe
www.iglobali.com/34gf5y/r34f3345g.exe
www.jesusdenazaret.com.ve/34gf5y/r34f3345g.exe

Curiously, the binary downloaded from each location is different, with the following MD5s:

CBE75061EB46ADABC434EAD22F85B36E
B06D9DD17C69ED2AE75D9E40B2631B42
FB6CA1CD232151D667F6CD2484FEE8C8

Each one phones home to a different location, the ones I have identified are:

109.234.38.35 (McHost.ru, Russia)
86.104.134.144 (One Telecom SRL, Moldova)
195.64.154.14 (Ukrainian Internet Names Center, Ukraine)

There may be other samples with other behaviour.

UPDATE 2

It is possible that this is dropping ransomware, not Dridex. One other download location identified here:

www.villaggio.airwave.at/34gf5y/r34f3345g.exe

This one has an MD5 of:

1FD40A253BAB50AED41C285E982FCA9C

Detection rate is 5/53 but I do not yet know where this phones home to.

UPDATE 3

That last sample phones home to:

91.195.12.185 (PE Astakhov Pavel Viktorovich, Ukraine)

according to this Hybrid Analysis.

Recommended blocklist:
109.234.38.0/24
86.104.134.128/25
195.64.154.14
91.195.12.185 

UPDATE 4

It appears that this is dropping some ransomware called "Locky" apparently by the makers of Dridex, according to this.

Malware spam: "receipt" / "Accounts" [accounts@aacarpetsandfurniture.co.uk]

This fake financial spam does not come from AA Carpets and Furniture, but is instead a simple forgery with a malicious attachment:

I have only seen a single copy of this spam, with an attachment 201602_4_2218.docm which has a VirusTotal detection rate of 5/54. Analysis is pending, but the payload is likely to be the Dridex banking trojan.

Attached is a file SKM_C3350160212101601.docm which comes in several different variants. The macro in the document attempts to download a malicious executable from:

sstv.go.ro/09u8h76f/65fg67n

This dropped a malicious executable with a detection rate of 6/54 which according to these automated analysis tools [1] [2] calls home to:

5.45.180.46 (B & K Verwaltungs GmbH, Germany)

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