Malware spam: "Sky.com / Statement of Account" and "Voice Mail / You have a new voice" via volafile.io

These two spam runs attempt to download malware from volafile.io. To give the folks at Volafile credit, all the malware I have seen linked to has been taken down. I suspect that the payload is the Dyre banking trojan.

Afternoon,

Please find the statement of account, download and view from the link below:

We look forward to receiving payment for the September invoice as this is now due for payment.

Malware spam: "Australian Taxation Office [noreply@ato.gov.au]" / "eFax message - 2 page(s)"

Apparently the Australian Taxation Office thinks I have a fax.. or perhaps it is something more sinister?

From:    Australian Taxation Office [noreply@ato.gov.au]
Date:    19 May 2015 at 12:48
Subject:    eFax message - 2 page(s)

Fax Message [Caller-ID: 408-342-0521]
You have received a 2 pages fax at 2015-05-19 08:18:16 AM EST.

* The reference number for this fax is

View this fax using your PDF reader.

Please visit www.eFax.com/en/efax/twa/page/help if you have any questions regarding this message or your service.
Thank you for using the eFax service!

Predictably, the link leads to a malicious download (this time at storage-ec2-24.sharefile.com) named Fax_00491175.zip and containing in turn a malicious executable Fax_00491175.scr.

This executable has a detection rate of 5/57. Automated analysis tools [1] [2] [3] shows that it downloads a further component from:

http://employmentrisk.com/images/1405uk77.exe

In turn, this has a detection rate of 4/57 and the Hybrid Analysis report indicates that it tries to communicate with 194.28.190.183 (AgaNet Agata Goleniewska, Poland).

There seem to be several different attachments, but for the sake of simplicity I have looked at just one. The Hybrid Analysis report shows this this is a MIME attachment that downloads and executes a script from pastebin[.]com/download.php?i=C5KGsRX3 which in turn downloads a malicious executable from  193.26.217[.]220:80/bt/get3.php (Servachok LTD, Russia) which is saved as crypted.120.exe.

This executable has a VirusTotal detection rate of 4/57. The Malwr and Hybrid Analysis reports indicates traffic to 5.63.154.228 (Reg.Ru, Russia) and also shows a dropped Dridex DLL with a detection rate of 3/57.

Each attachment is slightly different, but does contain the name of the recipient plus a random number (e.g. it-dept_0E78A3A5700B.doc). The payload is meant to be a multi-part MIME file, but many are corrupt and are either Base 64 encoded or are "404 Not Found" files.

If the file is correctly format, it should behave similarly to this Hybrid Analysis report, which says that it connects to several different IPs, but crucially also it downloads a malicious executable from 91.226.93[.]110/bt/get1.php (Sobis, Russia) and saves it as crypted.120.exe.

This malicious executable has a detection rate of 2/56 and the Malwr report says that it communicates with 46.36.217.227 (FastVPS, Estonia) and drops a Dridex DLL with a detection rate of 22/56.

Malware spam: "ATTN: Outstanding Invoices - [4697E0] [April|May]"

This spam comes with random senders and reference numbers, but in all cases includes a malicious attachment:

From:    Debbie Barrett
Date:    12 May 2015 at 11:14
Subject:    ATTN: Outstanding Invoices - [4697E0] [April|May]

Dear anthony,

Kindly find attached our reminder and copy of the relevant invoices.
Looking forward to receive your prompt payment and thank you in advance.

Kind regards
The attachment name combines the recipient's email address with the fake reference number, e.g. barry_51DDAF.xls which isn't actually an Excel file at all, but a multipart MIME file. Payload Security's Hybrid Analysis tools manages to analyse it though, showing several steps in the infection chain.

First a VBScript is downloaded from pastebin[.]com/download.php?i=5K5YLjVu

Secondly, that VBScript then downloads a file from 92.63.88[.]87:8080/bt/get.php (MWTV, Latvia) which is saved as crypted.120.exe, this has a detection rate of 2/57.

This component then connects to 46.36.217.227 (FastVPS, Estonia) and according to this Malwr report drops a Dridex DLL with a detection rate of 3/56.

The names and references change between different versions, but in all cases there is a malicious DOC file attached. This DOC has an unusual structure in that it is a some sort of MIME file containing a mixture of HTML and Base64-encoded segments.

My source has analysed that this downloads a VBS file from Pastebin at pastebin[.]com/download.php?i=FsYQqTaj which then downloads some sort of .NET binary from 91.226.93[.]14:8080/stat/get.php (Sobis, Russia)

This binary has a detection rate of 2/56 and according to automated analysis tools [1] [2] it communicates with:

46.36.217.227 (FastVPS, Estonia)

It also drops a DLL with an MD5 of f0d261147d2696253ab893af3d125f53 and a detection rate of 1/56.

Nepal Earthquake scam: savenepal.org

I was tipped off to this site by a contact, but it appears that there are some particularly dispicable scammers who have registered a fake website called savenepal.org which is soliciting donations via PayPal.

The site largely cloned from the legitimate ActionAid site which is genuinely seeking donations to go to Nepal.

ActionAid is "Registered charity no 274467" (it says so on the bottom of the page). SaveNepal.org claims to be "Registered charity no 276187", but we can check at the UK charities commission and we can see that the charity with this number is actually an orchestra.


Clicking "Donate" on the scam site leads to PayPal. It doesn't give much of a clue about the ownership of the fake site:


The WHOIS details for the domain are hidden using WhoIsGuard. These other sites appear to be live on the same server:

com-indexhtml.link
com-indexhtml.us
grantsekit.com

Out of these, only com-indexhtml.us has a non-anonymous WHOIS entry:

Registrant ID:                               C4E83B25FA8AD52D
Registrant Name:                             Frank J. Moore
Registrant Address1:                         2441 Byers Lane
Registrant City:                             Davis
Registrant State/Province:                   CA
Registrant Postal Code:                      95616
Registrant Country:                          United States
Registrant Country Code:                     US
Registrant Phone Number:                     +1.5307574940
Registrant Email:                            uscustomerhelp@gmail.com
Registrant Application Purpose:              P1
Registrant Nexus Category:                   C12


I'm pretty sure that those contact details are fake. Going back through historical WHOIS comes up with different contact details:

Registrant ID:                               29B0B5BBD7190398
Registrant Name:                             dinna  james
Registrant Address1:                         po box 876
Registrant City:                             dl
Registrant State/Province:                   dl
Registrant Postal Code:                      110098
Registrant Country:                          India
Registrant Country Code:                     IN
Registrant Phone Number:                     +1.918978978
Registrant Email:                            helpot80@gmail.com
Registrant Application Purpose:              P1
Registrant Nexus Category:                   C12


Of course, these contact details could also be false and there's no definite connection to savenepal.org yet. But out of curiosity, who is helpot80@gmail.com?  Googling doesn't reveal much, but it does show a copy of a conversation in the news.admin.net-abuse.email where someone who is claiming to use this email address is complaining about spam. If we then use Google Groups to find the original newsgroup post we see it was posted from an IP of 182.68.85.242 which is a dynamic Bharti Airtel IP in India, which does at least match the country in the WHOIS details.

Another Google result is this Phishtank entry listing social2013.com/rockgrade/ which appears to be a copy of the Rock Grade Management scam site I covered way back in 2011, indicating that perhaps these two scams are related. helpot80@gmail.com was listed as the owner of social2013.com before it expired in February 2015.

This WHOISology report links the address to several domains:

beauty6k.com
social2013.com
droughty.com
auto36.us
secure2013.us

Also, 94.242.255.129 has hosted many other domains, many of which appear to be scammy.

com-13.pw
com-21.us
com-indexhtml.us
news7d.com
mynews360.com
grantsekit.com
social2013.com
secured2014.com
usgrantskit.com
savenepal.org
com-indexhtml.link
huffingtonpost.com-indexhtml.link
dear.graphics

Many of these have the helpot80@gmail.com address listed in their historical WHOIS entries.

What else can we find out?

The email address is connected with this scammy looking Facebook page allegedly giving away "free laptops"



The email address also links to this Google+ profile naming them as "N. Al.". It also links to this YouTube channel with a single video about Payoneer. These Profiles indicate that helpot80@gmail.com has an interest in affiliate marketing, an activity with a mixed reputation.

I cannot prove that helpot80@gmail.com is connected with the savenepal.org, but they probably know whoever is behind it.

Remember, if you want to donate to ANY disaster charity, it is worth checking very carefully that you are dealing with the real thing and not a bunch of scammers.

Whoever "Huayu Ltd" are is irrelevant, as they aren't actually interested in registering these domains, even if they exist. Instead, this is an attempt by a rogue Chinese domain registrar to get you to buy overpriced and worthless domains.

In this case the spam mentions the domain cnwebregistry.cn, but chinaygregistry.com is also on the same server and will be similarly fraudulent.

This video I made a while ago explains the scam in more detail:

Malware spam: "INVOICE PD Will Comm" / "richard will [contactwill@hotmail.com]"

This malicious spam does not come from Will Communications but is instead a simple forgery with a malicious attachment.

From:    richard will [contactwill@hotmail.com]
Date:    28 April 2015 at 09:05
Subject:    INVOICE PD Will Comm

Thank-you for your payment!

Richard Will

Will Communications, Inc.
richard@willcommunications.com

The samples that I have seen are all corrupted, and the malicious attachment just appears as a jumble of Base 64 encoded text, although this may not be the case with every email. After extraction, the malicious Word document has a detection rate of 4/56 and it contains this malicious macro [pastebin]. In this case, the macro downloads a component from:

http://massachusettsselfstorage.com/62/927.exe

..this is saved as %TEMP%\johan3.2.b.exe and has a detection rate of 3/53. There may well be other documents that download from other locations, but the binary will be the same in all cases.

Automated analysis tools [1] [2] [3] show that it attempts to communicate with the following IP:

185.12.95.191 (RuWeb CJSC, Russia)

According the the Malwr report it drops a malicious Dridex DLL with a detection rate of 2/56.

Malware spam: "Colin Fox [colin@nofss.co.uk]" / "Invoice 519658"

This spam is not from Norwich Office Supplies but is instead a simple forgery. They have not been hacked (even if their website says they have).

Date:    24 April 2015 at 09:40
Subject:    Invoice 519658

Please find Invoice 519658     attached 
The attachment is Sales Invoice 519658.pdf [VT 2/57] This spam drops the Dridex banking trojan, but unlike other recent runs the attachment is a PDF file rather than an Office document. In fact, the PDF file contains a script that generates and drops a Word document named 6.doc [Malwr report, Payload Security report] [VT 4/55] which in turn contains a malicious macro that looks like this [pastebin].

There may be different versions of the macro, but in this case it downloads a component from:

http://bepminhchi.com/83/61.exe

..which is saved as %TEMP%\pierre6.exe. This binary has a detection rate of 4/57 and automated analysis tools [1] [2] [3] show an attempted network connection to:

Malware spam: "Australian Taxation Office - Refund Notification" / "Australian Taxation Office [noreply@ato.gov.au]"

G'day mate. Despite not being an Aussie and never having paid a single Australian cent in tax, apparently I'm due a tax refund from the Australian Tax Office. Bonzer!

From:    Australian Taxation Office [noreply@ato.gov.au]
Date:    21 April 2015 at 21:36
Subject:    Australian Taxation Office - Refund Notification

IMPORTANT NOTIFICATION

Australian Taxation Office - 22/04/2015

After the last calculation of your fiscal activity we have determined that you are eligible to receive a refund of 218.21 AUD.

To view/download your tax notification please click here or follow the link below :
https://www.ato.gov.au/AZItems.aspx?id=3673&category=Tax+legislation+and+regulations&sorttype=azindexdisplay&Disp=True?NotificationCode=report2104_4343697

Brett Newman, Tax Refund Department Australian Taxation Office 

Despite the "gov.au" site that apparently displays in the link, it actually leads to a download from i.nfil.es and it leads to a ZIP file called report2104.zip which in turn contains the malicious executable report2104.exe.

Currently this malware has a reasonable detection rate of 23/57. Out of various automated analysis tools, only the Payload Security Hybrid Analysis engine gave a decent result indicating that a connection was made to a legitimate but hacked site relianceproducts.com and then several versions of the same .EXE were downloaded, which this VirusTotal report indicates is the Dyre banking trojan. That same VirusTotal post also lists a number of C&C servers that you might want to block:

What's the scam? Notice that "Invited participants will only be responsible for their hotel accommodation and feeding cost at the Royal Queens Hotel." These is no hotel in London with the name "Royal Queens Hotel", but the scammers will magic one up for you to take pre-payment for your hotel.. and will then vanish with your money.


There are some similarly-named hotels in London, for example the Hotel Royal @ Queens, but this is not the same hotel. Be warned though that sometimes scammers do go to the effort of setting up a fake hotel website to make the scam more credible.

Avoid.

Malware spam: "Decisive notification about your Automated Clearing House payment"

This fake ACH spam leads to malware:

From:    aileen.alberts@[redacted]
Date:    16 April 2015 at 15:55
Subject:    Decisive notification about your Automated Clearing House payment


The Automated Clearing House transaction transfer, recently initiated from your company"s online bank account, has been rejected by the EPA.

Rejected ACH payment
Automated Clearing House transfer Case # L669461617
Transaction Total 27504.02 US Dollars
Email [redacted]
Reason of Termination Download full details

Please visit the link provided at the top to see more information about this problem.
The link in the email goes to a download location at dropbox.com which downloads a malicious Word document Automated_Clearing_House transaction9090.doc which contains this macro [pastebin].

I haven't had the time to analyse it fully, but it is rather different from other offerings. From what I can tell, it downloads an encrypted file [pastebin] from:

sundsvallsrk.nu/tmp/1623782.txt or
hpg.se/tmp/1623782.txt

And some sort of executable from Dropbox with a detection rate of 3/57. Automated analysis tools are inconclusive at the moment [1] [2] although the Payload Security report does show several dropped files including two malicious scripts [pastebin].

Of note is that one of the scripts downloads what looks like a PNG from:

savepic.su/5540444.png

For now, I would recommend blocking traffic to
sundsvallsrk.nu

This email message is actually a spam promoting a long-running scam where an unscrupulous party is attempting to sell overpriced and worthless domains to their intended victim.

Subject: [victimdomain] Registration
Priority: High

To whom it may concern:

We are the Registrars accredited by China Internet Network Information Center. We have something to confirm with you. On April 7, 2015, we received an application in which a company by the name Presg Group applied to register " victimdomain " as their Brand Name and some Asia domain names through our firm.

Now we are handling this registration. After our initial checking, we found that the name are identical to your company's. We need to check with you whether your company has authorized that company to register these names. If you have authorized this, we will finish the registration at once. If not, please let us know within 7 workdays, in which case we will dicuss the matter more thoroughly. If not otherwise advised within that time limit we will proceed with the registration for Presg Group . We will be waiting for your reply. Have a nice day!

Best Regards

Malware spam: "Invoice from Living Water" / "Natalie [mailto:accounts@living-water.co.uk]"

This fake invoice does not come from Living Water, but instead is a simple forgery with a malicious attachment.
From: Natalie [mailto:accounts@living-water.co.uk]

Subject: Invoice from Living Water

Dear Customer  :

Your invoice is attached.  Please remit payment at your earliest convenience.

Thank you for your business - we appreciate it very much.

Sincerely,

Living Water

In the sample that I received, the attachment was named Inv_300846161_from_Living_W.doc which has a VirusTotal detection rate of 1/55. This contains a malicious macro [pastebin] which downloads a file from the following location:

http://adlitipcenaze.com/353/654.exe

There are probably other download locations, but they will all have the same payload. This is saved as %TEMP%\rizob1.0.exe and currecntly has a detection rate of 6/57. Automated analysis tools [1] [2] [3] show attempted connections to the following IPs:

89.28.83.228 (StarNet, Moldova)
78.24.218.186 (TheFirst-RU, Russia)
37.140.199.100 (Reg.Ru Hosting, Russia)

According to this Malwr report it drops a Dridex DLL with a detection rate of 4/57.

Recommended blocklist:
89.28.83.228
78.24.218.186

Digital Networks CJSC aka DINETHOSTING and 79.137.224.0/20

A few years ago Digital Networks CJSC (DINETHOSTING) was hosting a significant amount of toxic crap in the 79.137.224.0/20 range (examples: [1] [2] [3] [4]). Although they still host a significant amount of crap, this particular range now looks almost clean and does have quite a few legitimate (mostly Russian) customers on it.

I ran an analysis on 1672 sites [csv] in this range and only two were tagged as malicious by Google and none by SURBL, which is actually less than I would expect on a sample of this size. I note that many sites have reputational problems at WOT which seem to be because of an expired Spamhaus listing (see this example).

If you've blocked this /20 then I suggest that it is reasonably safe to unblock, although I would regard other DINETHOSTING ranges with caution.
