"Sup" snowshoe spam from 208.71.174.32/27

Here's a strange spam I've been tracking for a couple of days:

Date:     Sun, 03 Aug 2014 20:56:48 -0700 [08/03/14 23:56:48 EDT]
From:     Olive [olive@platesat.us]
Subject:     Sup

The HTML in the body text reads:

<html>
<head>
<meta content="text/html; charset=utf-8" http-equiv="content-type">
<meta http-equiv="Content-Language" content="en-us"/>
</head>
<body>
<img src="http://www.gonename.us/unsubscribe.php?email=[redacted]">
</body>
</html>

The "IMG" is invalid and shows a placeholder.. making you think that it is broken, but in fact it is triggering the "unsubscribe" link in the email. So.. the email automatically unsubscribes its victims? No exactly.

A look at the root directory of www.gonename.us (143.95.38.234 = petyrbaelish.asmallorange.com) shows the inner workings of the spam:

The presence of unsubscribe.dat and unsubscribe.php is a characteristic of Maxprog MaxBulk Mailer which like all mailing list applications can be used for good or evil. MaxBulk Mailer does have an unsubscribe option which stores names the unsubsribe.dat file (hardly secure, I know), and what appears to be happening in this case is the the HTML has been altered slightly to make everyone unsubscribe.

Finnell's Corollary to the Rules of Spam states that spammers define "remove" as "validate which is exactly what is happening here.. when someone opens the email (if their email displays images) then it automatically confirms that they have opened it. A crude but effective way of confirming that the email address is valid.

At the time of writing, over 6800 email addresses have been validated for further spamming, a number that is increasing quite rapidly. Emails are held in plaintext and can be harvested by anyone.

No doubt the people who opened this email can look forward to a whole set of additonal spam in their inboxes.

All the sending IPs are in the 208.71.174.32/27 range (Network Data Center Host Inc, US). Each IP has a .us domain hosted on it, but the WHOIS details for each domain appear to be fake.

This attack started last week with a different range of sending addresses in the 188.165.94.176/28 (OVH, France / VertVPS, Canada) range sending victims to a spamvertised site of www.morehex.us which was configured in the same way. All those sites have now been suspended. Email subjects in that case were:
What's up?
Hey Sister
G'day

Whoever is running these spam servers has taken enormous pains to hide their identity, and they are also well-resourced enough to be able to rent server farms for a short period until they get terminated.

I've seen the following domains and IPs in the spam I have received myself, no doubt there are other domains and IPs too.

Warning: ipma2014.org (Institute of Project Management America)

Just a quick note to say that if you see an email referring to the site ipma2014.org then this is a new domain for the so-called Institute of Project Management America. Beware.

It is NOT related to the 28th IPMA World Congress which uses the domain ipma2014.com or any other legitimate professional organisation. You can read my research on the activities of the people behind this outfit here.

"Payroll Received by Intuit" spam / Cryptowall

I haven't seen any fake Intuit spam for a while. This one comes with a malicious attachment:

Date:     Fri, 1 Aug 2014 07:59:12 -0600 [09:59:12 EDT]
From:     Intuit Payroll Services [IntuitPayrollServices@payrollservices.intuit.com]

The attachment in this case is called Remittance.zip and it contains a malicious executable Remittance.exe which has a VirusTotal detection rate of 9/53.

According to the evidence of this very detailed ThreatTrack report [pdf], this is a version of Cryptowall. It makes network connections to various sites including the now-familiar 94.23.247.202.

I recommend that you block the following domains and IPs:

New York City Police "Homicide Suspect" spam using goo.gl shortener to spread malware

The bad guys are enjoying the goo.gl URL shortening service at the moment (remember, you can report goo.gl spam to goo.gl/spam-report). This spam is slightly unusual..

From:    ALERT@nyc.gov [ALERT@static-23-106-230-77.ipcom.comunitel.net]
Date:    1 August 2014 10:43
Subject:    Homicide Suspect

Bulletin Headline: HOMICIDE SUSPECT
Sending Agency: New York City Police
Sending Location: NY - New York - New York City Police
Bulletin Case#: 14-10078
Bulletin Author: BARILLAS #9075
Sending User #: 94265
APBnet Version: 287320

The bulletin is a pdf file. To download please follow the link below (Google Disk Drive service):

https://goo.gl/RwNKEA

The Adobe Reader (from Adobe.com) will display and print the bulletin best.

You can Not reply to the bulletin by clicking on the Reply button in your email software.

The link in the email is goo.gl/RwNKEA which goes to unionlawgroup.com/wp-content/images/Documents-43632.zip which is exactly the same payload as used in this spam.

Adding a "+" to the end of the URL reveals the click statistics

Blocking unionlawgroup.com is probably a good idea.

NatWest "You have a new Secure Message" spam uses goo.gl links to spread malware

This fake NatWest bank message uses the Goo.gl URL shortener to spread malware:

From:    NatWest [secure.message@natwest.com]
Date:    24 July 2014 10:39
Subject:    You have a new Secure Message

You have received a secure message from NatWest Bank

To read your secure message please click here. You will be prompted to open (view) the file or save (download) it to your computer. For best results, save the file first, then open it in a Web browser.
If you have concerns about the validity of this message, contact the sender directly.

First time users - will need to register after opening the attachment.
Help - https://securemail.natwest.com/websafe/ml/help?topic=RegEnvelope

The link in the email goes to goo.gl/dGDi7l and the downloads a ZIP file from berkleyequine.com/wp-includes/images/Documents-43632.zip, containing a malicious executable Documents-43632.scr which has a VirusTotal detection rate of just 1/54. The CAMAS report shows that the malware calls out to the following URLs;

94.23.247.202/0108uk1/SANDBOXA/0/51-SP2/0/
94.23.247.202/0108uk1/SANDBOXA/1/0/0/

firstfiresystems.com/css/slimbox/opened.rar

The characteristics of this malware are very similar to this one seen yesterday, and you can be assured that there are other goo.gl URLs and download locations in addition to the one listed here.

Because you can see the stats for any goo.gl URL just by adding a "+" on the end, it is possible to see who is clicking through. Oddly, there is not a single clickthrough from the UK where the NatWest bank is actually based.

Google don't make it easy to report spammy links and they are awfully slow to respond to reports, but their reporting form is at goo.gl/spam-report if you want to try it (I would recommend giving it a go).

"Scanned Image from a Xerox WorkCentre" spam

This is a thoroughly old school spam with a malicious attachment.

Date:     Thu, 31 Jul 2014 18:16:08 +0000 [14:16:08 EDT]
From:     Local Scan [scan.614@victimdomain]
Subject:     Scanned Image from a Xerox WorkCentre

You have a received a new image from Xerox WorkCentre.

Sent by: victimdomain
Number of Images: 5
Attachment File Type: ZIP [PDF]

WorkCentre Pro Location: Machine location not set
Device Name: victimdomain

Attached file is scanned image in PDF format.
Adobe(R)Reader(R) can be downloaded from the following URL: http://www.adobe.com/

Guess what.. it isn't an image at all, but a ZIP file with the unusual name of Image_[_var=partorderb].zip which contain a malicious executable Image_07312014.scr, scoring a measly 1/54 at VirusTotal.

The Comodo CAMAS report shows that the malware downloads components from the following locations:

94.23.247.202/3107us2/SANDBOXA/0/51-SP2/0/
94.23.247.202/3107us2/SANDBOXA/1/0/0/

There are some further clues in the VirusTotal comments as to what the malware does. Sophos has also seen the 94.23.247.202 (OVH, France) IP before.

Evernote "File has been sent" spam

I've never understood Evernote. Something to do with elephants I think. But this spam isn't from them anyway..

Date:     Thu, 31 Jul 2014 12:26:53 +0200 [06:26:53 EDT]
From:     EVERNOTE [lcresknpwz@business.telecomitalia.it]
Subject:     File has been sent [redacted]

DSC_9426679.jpg attached to the letter
Copyright 2014 Evernote Corporation. All rights reserved

The file attached is actually DSC_9426679.zip and not .jpg, containing a malicious executable DSC_8832966.exe with a VirusTotal detection rate of 7/53. The CAMAS report shows that the malware attempts to download an additional component from the following locations:

utilatas.com/333

These download locations are the same as yesterday's Amazon spam run. The downloaded file has a VT detection rate of 3/53.

The recommended blocklist is the same as yesterday.

"New fax" spam using goo.gl shortening service

Here are a couple of variations of a fax spam using the goo.gl shortening service:

From:    Fax [fax@victimdomain]

Download file at google disk drive service - dropbox.

https://goo.gl/t8jteI

_________________________________
File is scanned image in PDF format.
Adobe(A) Reader(R) can be downloaded from the following URL: https://www.adobe.com/

There seems to be an uptick of goo.gl spam.. if you receive something like this you can report it to goo.gl/spam-report as malware.

I've seen three different URLs:
goo.gl/1rBYjl
goo.gl/t8jteI
goo.gl/RmGnbr

These lead to the following download locations:
pinkfeatherproductions.com/wp-content/uploads/2014/06/Document-95722.zip
autoescuelajoaquin.com/images/Document-95722.zip
esys-comm.ro/images/Document-95722.zip

Obviously, this is a ZIP file. It contains a malicious executable Document-95722.scr which has a VirusTotal detection rate of just 1/54. The CAMAS report shows that the malware reaches out to the following locations to download further components:
andribus.com/images/images.rar
owenscrandall.com/images/images.rar

Incidentally, if you add a "+" to the end of the goo.gl URL you can see how many people have clicked through. For example:

164 clicks isn't a lot, but there are multiple URLs in use.

"Payslip" spam

Presumably terseness works with this kind of message:

From:    Richard Mason [richardm254@gmail.com]
Date:    30 July 2014 21:23
Subject:    Payslip

Please find attached the payment slip.

Attached is a file swift copy-Payment-Slip-$70,000.html which when it is opened up in your browser comes up with a popup box.

Clicking OK downloads an executable from www.greenexpress.ge/swift//payslip.exe which your are presumably meant to run. It's a bit of an odd way to do it, so perhaps there's a reason. The HTML is simple enough..

..but why bother doing it this way at all? Well, it makes it just a bit harder for email security software to find the link because the attachment is Base 64 encoded.

The malware itself has a VirusTotal detection rate of 31/53 which is frankly better than I'd expect. Automated analysis tools seem to time out or crash, which indicates that the malware is hardened against analysis, but the VT report does see traffic with a pattern that might be blockable if you have a webfilter:

"Order status -950533 30.07.2014.xls" spam

This body-text-less spam comes with a malicious attachment.

Date:     Wed, 30 Jul 2014 17:06:27 +0530 [07:36:27 EDT]
From:     Twila Garner [3f418d9@consolacionburriana.com]
Subject:     Order status -950533 30.07.2014.xls

Actually the body text isn't completely blank but does contain some bits of HTML.

<html>
<head>

<XSSCleaned_taghttp-equiv="content-type" content="text/html; charset=UTF-8">
</head>
<body text="#000000" bgcolor="#FFFFFF">
<br>
</

But the payload is the thing, in this case there is an archivecalled 950533-30.07.2014.zip containing a folder order-8301138-30.07.2014.xls which in turn contains a malicious executable order-8301138-30.07.2014.xls.exe which has a VirusTotal detection rate of 6/54.

The Comodo CAMAS report shows attempted downloads from the following connections:

jobengine.in/333
legusadvantage.com/333
davidtaylorartist.com/333
asustabletservisi.com/333
mycustomkidsbooks.com/333
redhorsesolutions.com/333
tencoolthings.com/333
wwwtokiodesign.com/333
extreme-bdsm-comics.com/333

A second file is downloaded from these locations with a VT detection rate of just 2/54. The CAMAS report is inconclusive.

I recommend the following blocklist:
jobengine.in
legusadvantage.com
davidtaylorartist.com
asustabletservisi.com
mycustomkidsbooks.com
redhorsesolutions.com
tencoolthings.com
wwwtokiodesign.com

QuickBooks "Important - Payment Overdue" spam has a malicious PDF attachment

This fake QuickBooks Invoice spam comes with a malicious payload:

From:    QuickBooks Invoice [auto-invoice@quickbooks.com]
Date:    29 July 2014 23:08
Subject:    Important - Payment Overdue

Please find attached your invoices for the past months. Remit the payment by 07/30/2014 as outlines under our "Payment Terms" agreement.

Thank you for your business,

Sincerely,
Josephine Shirley

The attached file (in this case invoice_7564675_07292014.pdf) contains an exploit with a VirusTotal detection rate of 7/53. I haven't had a chance to analyse the exploit myself yet.

Tuesday, 29 July 2014

Something evil on 31.210.96.155, 31.210.96.156, 31.210.96.157 and 31.210.96.158 (31.210.96.152/29)

[Note, an update to this can be found here]

I don't know quite what the exploit kit of the month is here, but the IP addresses 31.210.96.155, 31.210.96.156, 31.210.96.157 and 31.210.96.158 are currently serving up malware using hijacked GoDaddy domains, and are targeting victim websites by altering their .htaccess files to intercept traffic coming from search engines such as Google.

These IP addresses have been used for malware for some time and certainly historically they have been used for Ponmocup. I can't confirm that this is still the case, but given the bad IP and the obvious .htaccess hijack then it passed the Duck Test.

These IPs are allocated to Radore Veri Merkezi Hizmetleri A.S. in Turkey who control 31.210.64.0/18 which is a large block, so these IPs are probably a customer or even a customer of a customer.

VirusTotal reports for these IPs are pretty poor [1] [2] [3] [4]. I assume that they form part of an allocation 31.210.96.152/29 which I would very strongly recommend blocking that range, or indeed the entire /24 looks pretty worth

These domains all use the GoDaddy domaincontrol.com nameservers, which naturally means most of them are GoDaddy domains.. but not all of them, some are from other registrars. This list [pastebin] includes a selection of active subdomains that I can find.

I recommend permablocking the following IP range and temporarily blocking the following domains:

amazon.co.uk "Your Amazon order" spam

This fake Amazon spam comes with a malicious attachment:

Date:     Mon, 28 Jul 2014 13:15:57 +0200 [07:15:57 EDT]

Attached is a file Order-239-1744919-1697181.zip which in turn contains a malicious executable Order details 001-8821901-992107.exe which has a VirusTotal detection rate of 18/54.

The Comodo CAMAS analysis shows that the malware reaches out to a familiar set of URLs to download further components:

Something evil on 88.198.252.168/29 (Ransomware)

88.198.252.168/29 (Hetzner, Germany) is infected with a whole bunch of ransomware landing pages, like this:

In the past this IP range has been used to host a number of legitimate Austrian sites, but at the moment it appears to be hosting ransomware landing pages exclusively.

The domains in use are a combination of crappy .in domains registered to a series of fake addresses, plus a bunch of subdomains of legitimate domains that have been hijacked. What is interesting about these hijacked domians is that they all use afraid.org as namerservers.

This hijacking at afraid.org is because these particular domain users are using the free afraid.org service which allows anyone to create a subdomain of your domain and point is where they like (explained in this FAQ). The bad news is that this sort of hijacking is a quick way to ruin your domain's reputation. A full list of the subdomains and domain I can find is here [pastebin].

Although this is a Hetzner IP, it is suballocated to a customer who may or may not know anything about this abuse of the IPs in the range:

inetnum:        88.198.252.168 - 88.198.252.175
netname:        ANDY-CONTE

mnt-by:         HOS-GUN

Blocking these landing pages will probably not stop a PC from becoming infected with ransomware, but monitoring or blocking the following list may give you some intelligence as to what is happening on your own network.

"PLEASE SEND PI" spam / something evil on 198.27.110.192/26

"PI" in this case seems to refer to a Proforma Invoice rather than Π - but in fact the attachment is malware.

Date:     Fri, 25 Jul 2014 22:50:14 -0700 [01:50:14 EDT]
From:     OLINMETALS TRADING CO
Subject:     PLEASE SEND PI

Greetings,

Regarding our previous conversation about our urgent purchase, kindly
find attached PI and let us know if the quantity can fit in 40ft
container.
kindly revise the Proforma invoice so that we can proceed with an
advance payment as agreed.

We look forward to your urgent response with revised proforma invoice.

Thks & Rgds,
OLINMETALS TRADING CO., LTD
Tel : 0097143205171
Fax : 0097143377150

It sounds like a fiendish maths question from an obscure exam. How much Π can you fit in a 40ft container? Anyway, the attachment Order.zip contains a malicious executable klopppp890.exe which has a VirusTotal detection rate of 18/53. The ThreatExpert report [pdf] and ThreatTrack report [pdf] show that the malware phones home to walex2.ddob.us/sddob/gate.php on 198.27.110.200 (OVH Canada reassigned to Big Kesh, LLC, US).

Looking at the domains registered on 198.27.110.200 and the surrounding IPs there do seem to be a lot of malicious ones being used as malware C&Cs:

frank.ddob.us	198.27.110.196
walex.ddob.us	198.27.110.196	[1]
dino.ddob.us	198.27.110.197	[2] [3]
mrson.ddob.us	198.27.110.200
walex2.ddob.us	198.27.110.200	[4]
robert.xiga.us	198.27.110.200	[5]
daniel.ddob.us	198.27.110.201	[6]
robert.ddob.us	198.27.110.201	[7]
326.xiga.us	198.27.110.203
frannky.ddob.us	198.27.110.210	[9]
janet.ddob.us	198.27.110.211
sayee.ddob.us	198.27.110.211	[10]
dino.ddob.us	198.27.110.213	[11] [12]
biolo.xiga.us	198.27.110.216

I think this is enough evidence to block the entire 198.27.110.192/26 as a precaution (although there do appear to be a small number of legitimate sites too). For the record, this is suballocated to:

NetRange:       198.27.110.192 - 198.27.110.255

In the case of Big Kesh LLC I will be charitable and assume that this behaviour is happening without their consent.

In this case the link in the email goes to verzaoficial.com/css/fax_390392029_072514.exe which downloads a file with a VirusTotal detection rate of just 1/45. Automated analysis [pdf] is fairly inconclusive as to what it does.

Tiffany & Co "invoice 0625859 July" spam

This fake Tiffany & Co email has a malicious attachment:

Date:     Fri, 25 Jul 2014 17:32:38 +0800 [05:32:38 EDT]
From:     "J.Parker" [rcaukomti@tiffany.co.uk]
Subject:     invoice 0625859 July

Kindly open to see export License and payment invoice attached, meanwhile we sent the balance payment yesterday.
Please confirm if it has settled in your account or you can call if there is any problem.
Thanks

J.parker
Tiffany & Co.

Attached to the message is an archive invoice copy.zip which contains a folder invoice copy in which there is a malicious file invoice copy.exe which has a VirusTotal detection rate of 9/51. The CAMAS report shows that the malware downloads components from the following locations:

brandsalted.com/333
daisyblue.ru/333
expositoresrollup.es/333
fbcashmethod.ru/333
madrasahhusainiyahkl.com/333
sexyfoxy.ts6.ru/333
siliconharbourng.com/333
www.huework.com/333
www.martijnvanhout.nl/333
www.ricebox.biz/333
www.zag.com.ua/333

Those sites are similar to the one found in the recent "Birmingham Mail" spam run. I recommend that you block the following domains on your network:

brandsalted.com
daisyblue.ru
expositoresrollup.es
fbcashmethod.ru
madrasahhusainiyahkl.com
sexyfoxy.ts6.ru
siliconharbourng.com

"Help & Advice - Virgin Media Business" / Virginmedia Business spam

Date:     Fri, 25 Jul 2014 19:57:24 +0700 [08:57:24 EDT]

Attached is an archive file form_27429-070.zip which in turn contains a folder billing_form91_4352-2105.pdf which in turn contains a malicious executable billing_form91_4352-2105.pdf.scr which has a VirusTotal detection rate of 3/53. The Comodo CAMAS report indicates that is is largely the same in behaviour as this HMRC malware from earlier today.

HM Revenue and Customs "Notice of Underreported Income" spam

The second HMRC spam run of the day, this one contains a malicious link.

From:    HM Revenue and Customs [noreply@hmrc.gov.uk]
Reply-To:    HM Revenue and Customs [noreply@hmrc.gov.uk]
Date:    25 July 2014 12:19
Subject:    Notice of Underreported Income

Taxpayer ID: ufwsd-000007954108UK
Tax Type: Income Tax
Issue: Unreported/Underreported Income (Fraud Application)
Please review your tax income statement on HM Revenue and Customs ( HMRC ).Download your HMRC statement.
Please complete the form. You can download HMRC Form here.

In this case the link in the email goes to ecanovas.com/boceto/hmrc.exe which the user is expected to download and run. It has a VirusTotal detection rate of 3/51. Automated analysis tools are pretty inconclusive [1] [2] [3] but do reveal some of the behavioural activity.

HMRC "Tax Notice July 2014" spam

This fake HMRC tax notice comes with a malicious attachment:

Date:     Fri, 25 Jul 2014 16:48:37 +0900 [03:48:37 EDT]
From:     HMRC Revenue&Customs [Rosanne@hmrc.gov.uk]
Reply-To:     Legal Aid Agency [re-HN-WFCLL-OECGTZ@hmrc.gov.uk]

Dear [redacted] ,

Please be advised that one or more Tax Notices (P6, P6B) have been issued.

For the latest information on your Tax Notices (P6, P6B) please open attached report.
Document Reference: 34320-289.

The security and confidentiality of your personal information is important for us. If you have any questions, please either call the toll-free customer service phone number.

Attached is a file P6_rep_34320-289.zip which unZips to a folder called P6_rep(9432)_84632_732.doc which contains a malicious executable P6_rep(9432)_84632_732.doc.scr which has a VirusTotal detection rate of 4/53.

The CAMAS report shows that a second component is downloaded from 37.139.47.167/bt/2.exe which in turn has a VirusTotal detection rate of 5/52.

The IP address of 37.139.47.167 is in the same /24 as the two other IPs mentioned here. I would very strongly recommend blocking traffic to at least 37.139.47.0/24 or the whole 37.139.40.0/21 range (although there do seem to be some legitimate Russian-language sites in there). The IP belongs to:
