"inovice 0293991 September" spam

This spam mis-spells "invoice" in the subject line, and has an .arj file attached that contains a malicious binary.

Example subjects:
inovice 8958508 September
inovice 7682161 September
inovice 4868431 September
inovice 0293991 September

Body text:
This email contains an invoice file attachment

The name of the attachment varies, but is in the format invoice_8958508.arj which contains a malicious executable invoice_38898221_spt.exe which has a VirusTotal detection rate of just 3/54. The ThreatTrack report [pdf] and Anubis report show a series a DGA domains [pastebin]
 that are characteristic of Zbot, although none of these domains are currently resolving.

If your organisation can block .arj files at the mail perimeter then it is probably a good idea to do so.

"ACH Notification : ACH Process End of Day Report" spam / ACAS1104201336289204PARA7747.zip

This fake ACH (or is it Paychex?) email has a malicious attachment:

Date:      Tue, 5 Nov 2013 08:28:30 -0500 [08:28:30 EST]
From:      "Paychex, Inc" [paychexemail@paychex.com]
Subject:      ACH Notification : ACH Process End of Day Report

Attached is a summary of Origination activity for 11/04/2013 If you need assistance
please contact us via e-mail at paychexemail@paychex.com during regular business hours.

Thank you for your cooperation.  

Attached is a file ACAS1104201336289204PARA7747.zip which in turn contains an executable ACAS11042013.exe which has a VirusTotal detection rate of 7/46. Automated analysis [1] [2] shows an attempted connection to slowdating.ca on 69.64.39.215 (Hosting Solutions International, US). There are several legitimate sites on this server, however it is possible that the server itself is compromised.

The malware drops several files, including this one with a detection rate of 4/46 that also calls home to the same domain [1] [2]  and a payload file with another low detection rate of 5/46 that rummages through the system [1] [2]. The payload appears to be a Zbot variant.

The attachment SecureMessage.zip contains an executable SecureMessage.exe which has to be unencrypted with the password supplied in the email (which is kind of stupid for a supposedly secure mail), and this has a VirusTotal detection rate of just 6/46.

The Malwr analysis shows that this is a pony/gate downloader, first downloading from [donotclick]webmail.alsultantravel.com/ponyb/gate.php on 198.57.130.34 (Unified Layer / Bluehost, US) and then downloading one of the following:

[donotclick]a1bridaloutlet.co.uk/aiswY6.exe (5/45)
[donotclick]www.giftedintuitive.com/kQYjoPqY.exe (11/46)

Bank of America "Your transaction is completed" spam / payment receipt 26-07-2013.zip

This fake Bank of America spam has a malicious attachment:

Date:      Fri, 26 Jul 2013 15:50:32 +0200 [09:50:32 EDT]
From:      impairyd04@gmail.com

There is an attachment payment receipt 26-07-2013.zip which in turn contains the executable file payment receipt 26-07-2013.exe. This appears to be a Zbot variant with a pretty low detection rate of 9/46 at VirusTotal.

The Malwr report is the most detailed for this sample, and Anubis also has some useful information. Of note is that there is network traffic to the following IPs that seem to be pretty common for this Zbot / Zeus variant:

14.97.179.244
46.48.148.147
67.140.85.16
71.43.167.82

In the first version of this list I accidentally included the following Google IPs. Don't block these:

Something evil on 188.241.86.33

188.241.86.33 (Megahost, Romania) is a malware server currently involved in injection attacks, serving up the Blackhole exploit kit, Zbot and a side order of Cdorked [1] [2].

This IP hosts a variety of domains, some of which are purely malicious, some of which are hijacked subdomains of legitimate ones. Blocking the IP address is the easiest approach, else I would recommend blocking all the domains that are being abused:

In the case of the sample I have seen, there is an attachment Case_CC3DK9WJW8IG0F5.zip which unzips using the supplied password to Case_Fiserv_04162013.exe (note the date is encoded into the filename).

At the time of writing, VirusTotal results are just 5/46. The Comodo CAMAS report is here, the ThreatExpert report here and the ThreatTrack sandbox report can be downloaded from here (this is the most detailed one). This seems to be a Zbot variant.

Zbot sites to block 13/3/13

These domains and IPs seem to be active as Zbot C&C servers. The obsolete .su (Soviet Union) domain is usually a tell-tale sign of.. something.

Zbot sites to block 28/1/13

These domains and IPs are currently acting as C&C and distribution servers for Zbot. I would advise blocking these IPs and domains if you can.

There are three parts to the list: IPs with hosting company names, plain IPs for copy-and-pasting and domains identified on these servers.

Something evil on 82.165.38.206

There's something evil on 82.165.38.206 (1&1, Germany).. Zbot, basically. The WHOIS details are refreshingly honest about the intent of the evil domains on the server. There are some legitimate domains as well, so it looks like a hacked server.

Convincing look OWA fake leads to PDF exploit

There are getting spammed out at the moment:

From: automailer@blahblah.blah [mailto:automailer@blahblah.blah]
Sent: 13 January 2010 11:08
To: Victim Username
Subject: The settings for the username@blahblah.blah mailbox were changed

Dear user of the blahblah.blah mailing service!

We are informing you that because of the security upgrade of the mailing service your mailbox (username@blahblah.blah) settings were changed. In order to apply the new set of settings click on the following link:

http://blahblah.blah/owa/service_directory/settings.php?email=username@blahblah.blah&from=blahblah.blah&fromname=username

Best regards, blahblah.blah Technical Support.

Letter ID#NGTS7OTY8XPZX8FEUYTTTZ1PF

The displayed link isn't the actual link, underneath it points to something like:
http://blahblah.blah.vcrtp21.eu/owa/service_directory/settings.php?email=username@blahblah.bah&from=blahblah.blah&fromname=username

Clicking through the link takes you to a convincing looking OWA (Outlook Web Access) forgery page, populated with the victim's domain name and email address.

There are two exploits on the page, the first one is a drive-by download of an infected PDF file called pdf.pdf for which VirusTotal detection is only 10/41, detected by McAfee as Exploit-PDF.ac and various others. The executable file you are directed to download is also a bit patchy on detections.

Sender names include:

• operator@
• support@
• notifications@
• no-reply@
• system@
• alert@
• info@

..all on your local domain, obviously.

Subjects include:

• The settings for the blah@blah.blah mailbox were changed
• The settings for the blah@blah.blah were changed
• A new settings file for the blah@blah.blah mailbox
• A new settings file for the blah@blah.blah has just been released
• For the owner of the blah@blah.blah e-mail account
• For the owner of the blah@blah.blah mailbox

Some domains in use on this are:

• vcrtp1.eu
• vcrtp21.eu
• vcrtprsa21.eu
• vcrtpsa21.eu
• vcrtrsa21.eu
• vcrtrsr21.eu
• vcrtrsrp2.eu
• vcrtrsrp21.eu

..there are probably many more of a similar pattern.

WHOIS details are fake:

1800 N. Bayshore Drive
33132 Roma

Email:
wawddhaepny@yahoo.com

Domains are on a fast flux botnet, so there's no point listing IPs. However, nameservers are as follows:
ns1.raddoor.com
84.243.201.159 [Netrouting Data Facilities, Amsterdam]
ns2.raddoor.com
71.123.51.158 [Verizon Internet Services Inc, Aston]

84.243.201.159 [Netrouting Data Facilities, Amsterdam]
ns2.elkins-realty.net
71.123.17.61 [Verizon Internet Services Inc, Whitesboro]

Registrant details for raddoor.com are probably bogus:

Once your machine is infected, it probably gets infected with a Zbot variant as in these two previous examples.

"please update your blah@blah.blab mailbox" spam

Another version of the Zbot trojan coming in via email, much like this one.

From: operator@blah.blah Sent: 20 November 2009 15:21
To: Blah
Subject: please update your blah@blah.blah mailbox

Dear owner of the blah@blah.blah mailbox, You have to change the security mode of your account, from standart to secure. Please change the security mode by using the link below:

http://accounts.blah.blah.verzzi.org.uk/webmail/settings/noflash.php?mode=standart&id=[snip]&email=blah@blah.blah

So far verzzi.co.uk and verzzi.org.uk seem to be domains that are used for this, there are probably many others.

Target page is a fake Flash download:

Target file is flashinstaller.exe with patchy or generic detection at best, according to VirusTotal.

ThreatExpert report is here which could be useful if you are trying to disinfect a machine.

When infected, the machine calls home to 193.104.27.42 in the Ukraine, allegedly belonging to "Vladimir Vasulyovich Kamushnoy" but that could be fake.

In this case the email "came" from operator@victimdomain - filtering your own domain at the gateway (or the "operator" address) could be useful.

support@nacha.org: "Please review the transaction report"

This is the Zbot trojan or something, very much like this one.

From: Electronic Payments Association [mailto:support@nacha.org]
Sent: 12 November 2009 14:58
Subject: Please review the transaction report

Dear bank account holder, The ACH transaction, recently initiated from your bank account (by you or any third party), was rejected by the Electronic Payments Association. Please review the transaction report by clicking the link below:

Unauthorized ACH Transaction Report

The underlying link goes to nacha.org.fffazsf.org.uk which is itself hosted on some sort of Fast Flux botnet. The landing page attempts to get a user to download report.exe ( a Zbot variant). It also opens an IFRAME to 121.12.170.177 in China, a well-known malware domain.



VirusTotal shows patchy detections, still being analysed by ThreatExpert.

The domain name registration is obviously fake:

Piradius.net running Zbot infrastructure servers

Piradius.net appears to be up to its dark grey hat antics again with a server at 124.217.251.179 which is providing services to the current run of Zbot trojans, as seen (for example) with this recent ThreatExpert report.

Robtex reports the the server is also being used as the NS for a number of Zbot related domains, notably x2dns.ru, cedns.ru, updata-1.com, admin-systems.com, db-1.net, upd01.net, ssl-updates.net and several others connected with this spam run. 124.217.251.179 is also the download server for various Zbot components.

Although Piradius.net probably has many legitimate customers (primarily from Malaysia, Thailand and South-East Asia), it seems to have a lot of bad ones too (including Yohost.org). Prudent network administrators may want to consider blocking 124.217.224.0 - 124.217.255.255 which will probably not cause too many problems.
