Malware spam: "November Invoice #60132748" leads to Teslacrypt

This fake financial spam comes with a malicious attachment.


From:    Valarie Davenport
Date:    2 December 2015 at 11:59
Subject:    November Invoice #60132748


Hello ,

Please review the attached copy of your Electronic document.

A paper copy of this document is being mailed, but this email is being sent in addition for your convenience.

Thank you for your business.

Attached is a file invoice_60132748.zip which contains a malicious obfuscated script INVOICE_main_BD3847636213.js [Pastebin obfuscated / deobfuscated] and this downloads a malicious file from:

74.117.183.84/76.exe?1

It also tries to contact 5.39.222.193, but this times out. An attempt to download from bestsurfinglessons.com comes up with a 404 error.

The Malwr report and Hybrid Analysis indicates that this communicates with the following compromised domains:

ccfinance.it
ecaequeeessa.com
schonemaas.nl
cic-la-banque.org


Both those reports indicate that this is the Teslacrypt ransomware.


Furthermore, the Hybrid Analysis report also shows other traffic to:

tsbfdsv.extr6mchf.com
alcov44uvcwkrend.onion.to
rbtc23drs.7hdg13udd.com

Malware spam: "Your Adler Invoice No. UK 314433178 IN" / "service@adlerglobal.com"

This fake financial spam does not come from Adler Manufacturing Limited but is instead a simple forgery, It is meant to have a malicious attachment, but all of the samples I have seen are malformed.

Supposedly attached is a document MD220EML.XLS but instead all the samples I see just have a Base 64 encoded section instead. Shame. If you go to the effort of decoding them, they are two moderately detected malicious documents (VirusTotal results [1] [2]) which according to these Malwr reports [3] [4] downloads a binary from:

vanoha.webzdarma.cz/4367yt/p0o6543f.exe
det-sad-89.ru/4367yt/p0o6543f.exe

These download locations were seen earlier, but the payload has changed to one with a detection rate of 4/55.  Those earlier Malwr reports indicate malicious traffic to:

193.238.97.98 (PJSC DATAGROUP, Ukraine)

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

Malware spam: "Aline Payment Request" / "Bruce Sharpe [bruce@alinepumps.com]"


This fake financial spam is not from Aline Pumps but is instead a simple forgery with a malicious attachment. In any cases Aline are an Australian company, they would not be sending out invoices in UK pounds.

Attached is a file Statement_1973_1357257122414.doc which comes in at least three versions (although I have only seen two), with VirusTotal results of 4/55 [1] [2] and automated analysis [3] [4] shows download locations of:

pivarimb.wz.cz/4367yt/p0o6543f.exe
allfirdawhippet.com/4367yt/p0o6543f.exe


apparently there is another download location of

sebel.fr/4367yt/p0o6543f.exe

In any case, the downloaded binary is the same and has a detection rate of 3/55  The Malwr analysis and this Hybrid Analyis shows it phoning home to:

193.238.97.98 (PJSC DATAGROUP, Ukraine)

I strongly recommend that you block traffic to that IP.

Attached is a file P-ORD-C-10156-124658.xls which I have seen two versions of (VirusTotal results [1] [2]) which contain a malicious macro that looks like this [pastebin] which according to these automated analysis reports [3] [4] [5] [6] pulls down an evil binary from:

Attached is a file CAR014 151238.doc which comes in at least two different versions with a VirusTotal detection rate of 3/55 for both [1] [2]. According to these Malwr reports [3] [4] the macro in the document downloads a file from one of the following locations:

This binary has a detection rate of 3/54. The Malwr report for that file shows that it phones home to:

There are other bad IPs in the 94.73.155.8 - 94.73.155.15 range, so I strongly recommend that you block all traffic to 94.73.155.8/29.

Malware spam: "Sales Invoice OP/I599241 For ANDSTRAT (NO.355) LTD" / "orders@kidd-uk.com"

This fake financial spam is not from James F Kidd, but is instead a simple forgery with a malicious attachment:
From:    orders@kidd-uk.com
Date:    30 November 2015 at 13:42
Subject:    Sales Invoice OP/I599241 For ANDSTRAT (NO.355) LTD

 Please see enclosed Sales Invoice for your attention.

 Regards from Accounts at James F Kidd
 ( email: accounts@kidd-uk.com )
I have seen a single copy of this spam with an attachment invoice574206_1.doc which has a VirusTotal detection rate of 3/55.

This Malwr report indicates that in this case there may be an error in the malicious macro [pastebin]. The Hybrid Analysis report is inconclusive. This document is presumably attempting to drop the Dridex banking trojan.

UPDATE

I have received two more samples, one names invoice574206/1.pdf and the other invoice574206/1.doc. Both are Word documents (so the one with the PDF extension will not open). The VirusTotal detection rates are 7/54 and 4/55. One of these two also produces an error when run.

The working attachment (according to this Malwr report and Hybrid Analysis report) downloads a malicious binary from:

bjdennehy.ie/~upload/89u87/454sd.exe

This has a VirusTotal detection rate of 3/54. Automated analysis tools [1] [2] [3] [4] show malicious traffic to:

The spam is almost identical to this one which led to Nymaim ransomware.

In this particular spam, the email went to a landing page at updates.intuitdataserver-1.com/sessionid-7ec395d0628d6799669584f04027c7f6 which then attempts to download a fake Firefox update

This executable has a VirusTotal detection rate of 3/55, the MD5 is 592899e0eb3c06fb9fda59d03e4b5b53. The Hybrid Analysis report shows the malware attempting to POST to mlewipzrm.in which is multihomed on:

The download location uses a pair of nameservers, NS1.MOMEDEFER.PW and NS1.PRIZEBROCK.PW. If we factor in the NS2 servers as well, we get a set of malicious IPs:

Malware spam: "Message from mibser_00919013013"

I have only one sample of this rather terse email with no body text:
From:    scan@victimdomain
Reply-To:    scan@victimdomain
To:    hiett@victimdomain
Date:    30 November 2015 at 09:22
Subject:    Message from mibser_00919013013
The spam appears to originate from within the victim's own domain, but it does not. In the sample I saw, the attachment was named Smibser_00915110211090.xls, had a VirusTotal detection rate of 3/54 and contained this malicious macro [pastebin]. .

According to this Hybrid Analysis report and this Malwr report the macro downloads a malicious executable from:

velitolu.com/89u87/454sd.exe

This binary has a detection rate of 3/55. Automated report tools [1] [2] show network traffic to:

94.73.155.12 (Cizgi Telekomunikasyon Anonim Sirketi, Turkey)

89.189.174.19 (Sibirskie Seti Novokuznetsk, Russia)
5.63.88.100 (Centr, Kazakhstan)


The payload is likely to be the Dridex banking trojan:

I have received several copies of the spam with the same attachment named S-INV-BROOKSTRO1-476006.doc with a VirusTotal detection rate of 1/54 and which contains this malicious macro [pastebin].

This Malwr report shows the macro downloads from:

kidsmatter2us.org/~parentsm/76f6d5/54sdfg7h8j.exe

The executable has a detection rate of 3/55. The Hybrid Analysis report shows network traffic to:

Random "Payment" spam leads to Dridex

I have only seen one version of this spam message so far:

From:    Basia Slater [provequipmex@provequip.com.mx]
Date:    26 November 2015 at 12:00
Subject:    GVH Payment

I hope you had a good weekend.
Please check the payment confirmation attached to this email. The Transaction should appear on your bank in 2 days.

This sample had a document name of I654WWFR3C6.doc which has a VirusTotal detection rate of 6/55, containing this malicious macro [pastebin]. The Malwr report for this version indicates a download from:

harbourviewnl.ca/jo.jpg?6625

According to that Malwr report, it drops a file YSpq2bkGVIi5yaPcv6667.exe (MD5 6c14578c2b77b1917b3dee9da6efcd56) which has a detection rate of 1/53. The Hybrid Analysis report and Malwr report for that indicates malicious traffic to:

94.73.155.10 (Telekomunikasyon Anonim Sirketi, Turkey)
199.175.55.116 (VPS Cheap INC, US)


Note that 94.73.155.12 is mentioned in this other Dridex report today, both IPs form part of a small subnet of  94.73.155.8/29 suballocated to one "Geray Timur Akkurt".

My contacts (you know who you are, thank you) indicate that the emails are generated according to the following pattern:

> From: (random)

Malware spam: Serafini_Billing_Statement 2003 / Statement.zip leads to Cryptowall

This fake financial spam leads to ransomware:
From:    Scrimpsher [mumao82462308wd@163.com]
Date:    24 November 2015 at 16:57
Subject:    Serafini_Billing_Statement 2003
Signed by:    163.com

Hi Please see attached a copy of your statement for the month of Nov 2015
Sincerely
Lynda Ang
As with many recent ransomware attacks, this appears to have been sent through webmail (it really is from 163.com, it is not being spoofed). Attached is a file Statement.zip which contains a malicious javascript statement.js [pastebin] [VT 7/53]  which then downloads a component from:

46.30.45.73/mert.exe

That IP belongs to Eurobyte LLC in Russia. I recommend that you block it.

This is saved as %TEMP%\122487254.exe and it has a VirusTotal detection rate of 5/55 and an MD5 of 68940329224ab93ce4b688df33a9274f. The application's icon and metadata is designed to make it look like a copy of VNC, but instead the VirusTotal detection indicates that it is Cryptowall. This Hybrid Analysis report demonstrates the ransomware in action most clearly.




One unusual characteristic is that it POSTs to a lot of webservers (also listed in these reports [1] [2] [3]) although I don't know how significant it is. Almost all the domain names being with "A":

Malware spam: FEDERAL RESERVE BANK

This spam does not come from the Federal Reserve Bank, but is instead a simple forgery with a malicious attachment:

From     "FDIC, Federal Reserve Bank"
Date     Tue, 24 Nov 2015 15:14:19 +0200
Subject     IMPORTANT!

FEDERAL RESERVE BANK

Important:
You are getting this letter in connection with new directive No. 172390635 issued
by U.S. Treasury Department, Federal Reserve and Federal Deposit Insurance Corporation
(FDIC). The directive concerns U.S. Federal Wire and ACH online payments.

We regret to inform you that from 11/24/2015 till 11/27/2015 definite restrictions
will be applied to all Federal Wire and ACH online transactions.

It's essential to know all the restrictions and the list of affected institutions.
The process of working with online transactions is mostly very tense, so it's possible
to overlook the applied restrictions, that may be very important for you.

More detailed information regarding the affected institutions and U.S. Treasury Department
restrictions is contained in the attached document.

Federal Reserve Bank System Administration

Alternative headers:
From    U.S. FRBank [admin@frb.com]
Date    24 November 2015 at 12:59
Subject    Attention!FED Wire and ACH Restrictions Applied!
From     FEDERAL RESERVE BANK [admin@usfrb.com]
Date     Tue, 24 Nov 2015 21:33:45 +0300
Subject     FED Wire and ACH Restrictions. IMPORTANT!

From     "USA FEDERAL RESERVE BANK" [security@frbservices.com]
Date     Tue, 24 Nov 2015 10:59:40 -0500
Subject     U.S. Treasury Department. FED Wire and ACH Restrictions Applied.

 Attached is an Excel file made up of part of the recipient's domain name plus a random number. So far I have seen two samples of this (VirusTotal [1] [2]) the latter of which is corrupt. The woirking one contains a macro that looks like this.

According to this Malwr report, the macro respectively POSTs and GETs from the following URLs:

rmansys.ru/utils/inet_id_notify.php
s01.yapfiles.ru/files/1323961/435323.jpg

Also, network communication is made with two other IPs, giving the following potentially malicious hosts:

185.26.97.120 (First Colo / Fornex, Germany)
90.156.241.111 (Masterhost, Russia)
89.108.101.61 (Agava Ltd, Russia)
95.27.132.170 (Beeline Broadband, Russia)


That .JPG file is actually an executable with a detection rate of 5/55. The Hybrid Analysis report shows all sorts of interesting things going on, but no clue as to what the purpose of the malware actually is. Those reports and this Malwr report shows some additional traffic:

217.197.126.52 (e-Style ISP, Russia)
88.147.168.112 (Volgatelecom, Russia)


According to this Malwr report it drops all sorts of files including _iscrypt.dll [VT 0/54] and 2.exe [VT 2/54] which is analysed in this Malwr report and this Hybrid Analysis report. It is unclear as to what it does (ransomware? remote access trojan?), but it appears that the installation may be password protected.

Attached is a file 20151009144829748.doc of which I have seen two versions (VirusTotal results [1] [2]) and which contain a macro like this [pastebin].

Analysis of these documents is pending, but the payload is likely to be the Dridex banking trojan.

Frustratingly, it looks like the web host has suspended newhopecare.co.uk which is not helpful in these circustances, as it stops the victim company from posting a warning.

buzmenajerlik.com.tr/65y3fd23d/87i4g3d2d2.exe
irisbordados.com/65y3fd23d/87i4g3d2d2.exe


This executable has a detection rate of 4/52 and according to that VT report and this Malwr report there is network traffic to:

157.252.245.32 (Trinity College Hartford, US)
89.32.145.12 (Elvsoft SRL, Romania / Coreix, UK)


Interesting, if you look at the Hybrid Analysis report and others, the executable masquerades as mbar.exe / Malwarebytes Anti-Rootkit. The payload is most likely to be the Dridex banking trojan.

Malware spam: "Jean Pierre Kibung" / "0150363108788101_02416060_1.xls"

This spam looks like an advanced free fraud, but instead it comes with a malicious attachment. The email appears to originate from within the victim's own domain, but this is a simple forgery and does not mean that you have been hacked.

The telephone number does match that of a genuine company in Jersey, but they are not sending this spam. The attachment is named 0150363108788101_02416060_1.xls and so far I have seen just one version of this with a VirusTotal detection rate of 4/53. It contains this malicious macro [pastebin].

Analysis of the spreadsheet is pending, but the payload is almost definitely the Dridex banking trojan.

UPDATE

Sources tell me there are at least two variants with download locations of:

betterimpressions.com/~impressions/65y3fd23d/87i4g3d2d2.exe
192.186.227.64/~irma1026/65y3fd23d/87i4g3d2d2.exe


This has an MD5 of d410a45dc4710ea0d383dee81fbbcb6f and a VirusTotal detection rate of 4/52. According to that VirusTotal report and this Malwr report, it makes a network connection to:

157.252.245.32 (Trinity College, US)

I strongly recommend that you block traffic to that IP.

The attachment is named 1630884720.doc which comes in at least two versions (VirusTotal analysis [1] [2]) and which contains a malicious macro like this [pastebin]).

Analysis of the documents is still pending (please check back), although the payload is almost definitely the Dridex banking trojan.

UPDATE

The Hybrid Analysis of the two documents [1] [2] shows attempted downloads from the following locations:

bhoomiconsultants.com/8i65h4g53/o97i76u54.exe [active]
bhairavraffia.com/8i65h4g53/o97i76u54.exe [file not found]

Date:    19 November 2015 at 10:27
Subject:    [Shipping notification] N3043597 (PB UK)
There is no body text and the "N" number is randomly generated. All samples I have seen contain a file called shipping-notification.xls which is in the same in all cases, containing this malicious macro [pastebin] and it has a VirusTotal detection rate of 2/54. The comments on that VirusTotal report plus this Hybrid Analysis report indicate a malicious binary is downloaded from:

iwcleaner.co.uk/8i65h4g53/o97i76u54.exe

This has an MD5 of e0d24cac5fb16c737f5f016e54292388 and a detection rate of 2/54 and this Hybrid Analysis report shows malicious traffic to the following IP (which I recommend you block):

182.93.220.146 (Ministry of Education, Thailand)


The payload is almost definitely the Dridex banking trojan.
