Keeping Money Mule Recruiters on a Short Leash - Part Four


UPDATED: Saturday, April 10, 2010: Some of the mule recruitment sites appear to be interested in something else, rather than recruiting mules -- must be the oversupply of people unknowingly participating in the cybercrime ecosystem.

Several of the domains (for instance ortex-gourpinc.tw  and augmentgroupinc.tw) are not accepting registrations, instead, but are attempting to trick the visitor into downloading and executing a bogus psychological test.

"Below is a test prepared by professional psychologists and is required in order to be considered a competent candidate for the offered position. After successful completion of your test, you will be asked to register on our web site. If you are not ready to register right away, please wait to take the test at a later point. To REGISTER, simply run the test and you will be prompted to click on the "Register Now" button at any time and you will be redirected to the login page, without having to take the test again.


*This test is under development and we are grateful for all comments and suggestions." *If you are having trouble running the test and your computer is requesting administrative rights, download the test and simply right-click on the Test icon and select "Run As Administrator" from the menu."

- testAugmentInc.exe - Result: 3/38 (7.9%) - Trojan/Win32.Chifrax.gen; Reser.Reputation.1
- testOrtexGroup.exe - Result: 3/39 (7.7%) - Trojan/Win32.Chifrax.gen; Reser.Reputation.1

UPDATED: AS34305, EUROACCESS has taken down the IPs within their network. The money mule recruiters naturally have a contingency plan in place, and have migrated to  AS38356 - TimeNet (222.35.143.112; 222.35.143.234; 222.35.143.235; 222.35.143.237) and AS21793 - GOGAX (76.76.100.2; 76.76.100.4; 76.76.100.5).


Based on the already established patterns of this group, it was only a matter of time until they re-introduced yet another portfolio of money mule recruitment domains, combining them with spamvertised recruitment messages, and forum postings.

Just like their campaign from last month (Keeping Money Mule Recruiters on a Short Leash - Part Three) the current one is once again interacting exclusively with AS34305, EUROACCESS Global Autonomous System, including the newly introduced name servers.

What has changed? It's the migration towards the use of fast-flux infrastructure for ZeuS crimeware serving campaigns, and in an isolated incident profiled in this post, a money mule recruitment campaign that's also sharing the same fast-flux infrastructure. Combined with the BIZCN.COM, INC. domain registrar's practice of accepting domain registrations using example.com emails, next to ignoring domain suspension requests - you end up with the perfect safe haven for a cybercrime operation.

In March, 2010, it took EUROACCESS less then 10 minutes to undermine their campaigns, including ones residing within the AS of a cyber-crime friendly customer known as 193.104.22.0/24 KratosRoute. However, it's interesting to observe their return to the same ISP, given that they were within a much more cybercrime-friendly neighborhood once EUROACCESS kicked them out last month.

Although the take down activities from last month may seem to have a short-lived effect, now that they're not only back, but are once again abusing EUROACCESS, the loss of OPSEC (operational security) did happen, just like it happened in the wake of the TROYAK-AS takedown.

Let's dissect the currently ongoing campaign, and emphasize on a second money mule recruitment campaign, that's not just using a fast-flux infrastructure, but is also connected to hilarykneber@yahoo.com (The Kneber botnet - FAQ).


Spamvertised, and parked domains on 85.12.46.3; 85.12.46.2; 193.104.106.30 - AS34305, EUROACCESS Global Autonomous System are as follows:

It's been a while, since I came across a money mule recruitment campaign using fast-flux infrastructure (Money Mule Recruiters use ASProx's Fast Fluxing Services) that's also currently being used by domains registered using the same emails as the original Hilary Kneber campaigns (Celebrity-Themed Scareware Campaign Abusing DocStoc) from December, 2009, as well as related mule recruitment campaigns (Dissecting an Ongoing Money Mule Recruitment Campaign) from February, 2010.

Moreover, one of the domains sharing the fast-flux infrastructure with the money mule recruitment site asapfinancialgroup.com - Email: admin@asapfinancialgroup.com, was also profiled in last month's "Zeus Crimeware/Client-Side Exploits Serving Campaign in the Wild".



The following ZeuS crimeware, client-side exploits service, and malware phone back C&C domains, all share the same fast-flux infrastructure:

Money Mule Recruitment Campaign Serving Client-Side Exploits

Remember Cefin Consulting & Finance, the bogus, money mule recruitment company that ironically tried to recruit me last month?

They are back, with a currently ongoing money mule recruitment campaign, this time not just attempting to recruit gullible users, but also, serving client-side exploits (CVE-2009-1492; CVE-2007-5659) through an embedded javascript on each and every page within the recruitment site.
Let's dissect the campaign, expose the client-side exploits serving domains, the Zeus-crimeware serving domains parked within the same netblock as the mule recruitment site itself, to ultimately expose a bogus company for furniture hosting a pretty descriptive cv.exe that is dropped on the infected host.

Initial recruitment email sent from financialcefin@aol.com:

Copyright Lawsuit Filed Against You Themed Malware Campaign

Having just received a copy of what appears to be the last active domain involved in last week's "Copyright Lawsuit filed against you" themed malware campaign, it's time to conduct a brief assessment of its inner workings.

Subject used: Copyright Lawsuit filed against you
Sample message: March 24, 2010
Crosby & Higgins
350 Broadway, Suite 300
New York, NY 10013

To Whom It May Concern: 

On the link bellow is a copy of the lawsuit that we filed against you in court on March 11, 2010. Currently the Pretrail Conference is scheduled for April 11th, 2010 at 10:30 A.M. in courtroom #36. The case number is 3485934. The reason the lawsuit was filed was due to a completely inadequate response from your company for copyright infrigement that our client Touchstone Advisories Inc is a victim of Copyright infrigement
www.touchstoneadvisorsonline.com /lawsuit/suit_documents.doc

Touchstone Advisories Inc has proof of multiple Copyright Law violations that they wish to present in court on April 11th, 2010.

The same phone back IP was also profiled in another campaign from January, 2010.

Clearly, the cybercriminals behind it are aiming to stay beneath the radar, by relying on not so well profiled malicious infrastructure, combined with newly introduced campaigns in an attempt to make it harder to establish historical connections (Read about the "aggregate-and-forget" concept in respect to botnets/malware) between the rest of the their malicious activities.

Zeus Crimeware/Client-Side Exploits Serving Campaign in the Wild

UPDATED: Friday, March 26, 2010: In a typical multi-tasking fashion like the one we've seen in previous campaigns, more typosquatted domains are being introduced, this time using the well known IRS Fraud Application theme. What's worth pointing out is that, just like the "Scareware, Sinowal, Client-Side Exploits Serving Spam Campaign in the Wild" campaign from last week, the current one is also launched on Friday.

The reason? A pointless attempt by the gang to increase the lifecycle of the campaign.
- Sample URL: irs.gov.faodqt.com.pl /fraud.applications/application/statement.php
- Client-side exploits serving iFrame URL: klgs.trfafsegh.com /index.php
- Sample detection rate: tax-statement.exe - Trojan-Spy.Win32.Zbot - Result: 29/42 (69.05%), phones back to shopinfmaster .com/cnf/shopinf.jpg

One of TROYAK-AS's most aggressive customers (used to host their Zeus C&Cs there) for Q1, 2010, is once again (latest campaign is from March 12th 2010 - Scareware, Sinowal, Client-Side Exploits Serving Spam Campaign in the Wild) attempting to build a crimeware botnet, by spamvertising the well known PhotoArchive theme, in between serving client-side exploits using an embedded iFrame on the domains in question.


In terms of quality assurance, the campaign is continuing to use it's proven campaign structure. The actual pages are hosting a binary for manual download, in between the iFrame which would inevitably drop the Zeus crimeware.

Just like in previous campaigns, the gang continues to exclusively registering its domains using the ALANTRON BLTD. domain registrar. Let's dissect the ongoing campaign's structure, and expose the domains, and ASs participating in it.

Sample URL/subdomain structure: 
archive.pasweq.co.kr /id1007zx/get.php?email=email@mail.com
photostock.pasweq.co.kr
archives.pasweq.co.kr
 
letitbit.pasweq.co.kr
photobank.pasweq.co.kr

photosbank.pasweq.co.kr

photostock.pasweq.co.kr

Sample iFrames embedded on the pages include: cogs.trfafsegh.com /index.php - 59.53.91.192 - Email: maple@qx8.ru; klgs.trfafsegh.com /index.php

Sample iFrame campaign structure:
- cogs.trfafsegh.com /index.php
    - cogs.trfafsegh.com /l.php
        - cogs.trfafsegh.com /statistics.php

- klgs.trfafsegh.com /index.php
    - klgs.trfafsegh.com /l.php
        - klgs.trfafsegh.com /statistics.php

Parked on the same IP where the iFrame domain is are also the following Zeus C&Cs - dogfoog.net - Email: drier@qx8.ru; countrtds.ru - Email: thru@freenetbox.ru - AS4134 (CHINANET-BACKBONE No.31,Jin-rong Street)

Detection rates: zeus.js - Trojan.JS.Agent.bik - 1/41 (2.44%) serving update.exe - PWS:Win32/Zbot.gen!R - Result: 17/42 (40.48%), PhotoArchive.exe - Trojan.Zbot - Result: 18/41 (43.91%). The client-side exploitation is relying on the Phoenix Exploit's Kit.
