Conficker's Scareware/Fake Security Software Business Model

It doesn't take a rocket scientist to conclude that sooner or later the people behind the Conficker botnet had to switch to monetization phase, and start earning revenue by using well proven business models within the cybercrime ecosystem.

Interestingly -- at least for the time being -- there's no indication of mainstream advertising propositions offering partitioned pieces of the botnet, managed fast-fluxing services (Managed Fast Flux Provider; Managed Fast Flux Provider - Part Two), hosting of scams and spam, examples of which we've already seen related cases where a money mule recruitment agency was using ASProx's fast-flux network services, next to Srizbi's botnet managed spam service propositions.

How come? Pretty simple, starting from the fact that scareware/fake security software as a monetization process remains the most liquid and efficiently monetized asset the underground economy has at its disposal. The scheme is so efficient that the money circulating within the affiliate networks are often an easy way for cybercriminals to quickly money launder large amounts of money in a typical win-win revenue sharing scheme.

The Conficker gang is monetization-aware, that's for sure. But they forget a simple fact - that in a cybercrime ecosystem visibility is not just proportional with decreased OPSEC (Violating OPSEC for Increasing the Probability of Malware Infection), but also, that despite their risk-decreasing revenue sharing model, the "follow the money trail" practice becomes more and more relevant.

The most recent variant (Net-Worm.Win32.Kido.js) is the group's second attempt to monetize the botnet, following by the original Conficker variant's traffic converter connection pushing fake security software. According to Aleks Gostev at Kaspersky Labs:

"One of the files is a rogue antivirus app, which we detect as FraudTool.Win32.SpywareProtect2009.s. The first version of Kido, detected back in November 2008, also tried to download fake antivirus to the infected machine. And once again, six months later, we’ve got unknown cybercriminals using the same trick. The rogue software, SpywareProtect2009, can be found on spy-protect-2009.com., spywrprotect-2009.com, spywareprotector-2009.com."

Regular researchers/law enforcement followers of the Diverse Portfolio of Fake Security Software series are pretty familiar with the SpywareProtect brand. Therefore, it's time to familiarize ourselves with the rogue SpywareProtect through the revenue earning scheme the latest Conficker variant is using. Among the currently active/recently registered SpywareProtect portfolios are managed by Geraldevich Viktus Email: krutoymen2009@inbox.ru and conveniently just like Kaspersky states, are all parked in Ukraine.

In case you remember according to SRI International's Analysis of the Conficker worm, the authors did signal a national preference since the first release "randomly generates IP addresses to search for additional victims, filtering Ukraine IPs based on the GeoIP database." and also "Conficker A incorporates a Ukraine-avoidance routine that causes the process to suicide if the keyboard language layout has been set to Ukrainian." followed by a third Ukrainian lead, namely the fact that "on 27 December 2008 we stumbled upon two highly suspicious connection attempts that might link us to the malware authors.  Specifically,  we observed two Conficker B URL requests sent to a Conficker A Internet rendezvous point: * Connection 1: 81.23.XX.XX - Kyivstar.net, Kiev, Ukraine; Connection 2: 200.68.XX.XXX - Alternativagratis.com, Buenos Aires, Argentina."

SpywareProtect's current portfolio is hosted in Ukraine as follows:
spy-wareprotector2009 .com (94.232.248.53) Ukraine Bastion Trade Group, AS48841, EUROHOST-AS Eurohost LLC
spyware-protector-2009 .com
spy-protect-2009 .com
spywprotect .com


The second portfolio is also parked in Ukraine as follows:
sysguard2009 .com (195.245.119.131) AS34187, RENOME-AS Renome-Service: Joint Multimedia Cable Network Odessa, Ukraine
swp2009 .com
spwrpr2009 .com
alsterstore .com
adwareguard .net


In a typical multitasking fashion, a connection between some of these very latest SpywareProtect portfolios (e.g spywrprotect-2009 .com) can be established with Zeus crimeware campaigns, since particular droppers have been known to have been installing the scareware next to Zeus crimeware used to be hosted at the following locations:

capitalex .ws/adv.bin (213.155.10.176)
cashtor .net/tor22/tor.bin (91.193.108.222)
goldarea .biz/adv.bin (91.197.130.39)

It's also worth pointing out that every time the Conficker authors claim their payments from the affiliate network in question, they expose themselves which makes me wonder one thing. Are the hardcore Conficker authors directly earning revenue out of the scareware, or are they basically partitioning the botnet and selling it to someone who's monetizing it and naturally breaking-even out of their investment?

In a network whose activities will inevitably start converging with the rest of the cybercrime ecosystem's participants' activities -- the Waledac connection -- it's crucual to keep the track-down-and-prosecute process as simple as possible. In this case - the Conficker authors'/customers of their botnet services asset liquidity obsession, may easily end up in someone's $250k reward claim. Patience is a virtue.

A Diverse Portfolio of Fake Security Software - Part Eighteen

With Microsoft's latest Security Intelligence Report indicating that scareware/fake security software continues growing, it's worth exposing some of the currently circulating rogue security software domains, their registrants, and the usual "Deja Vu" moment putting the spotlight on well-known RBN web properties, whose exposure demonstrates that some of the groups that I've been tracking are still alive and kicking, but this time are much more actively monetizing their cybercrime committing capabilities.

Now comes the deja vu moment. At 174.129.241.185 and 174.129.244.106 we also have parked ilovemyloves .com one of the domains used in the iFrame attack during the "Possibility Media's Malware Fiasco" back in 2007 which was then parked at the RBN's HostFresh ifrastructure (58.65.239.28). Behind the malware campaign back then was the New Media Malware Gang" (Part Three; Part Two and Part One) which was not only using RBN services, but was directly cooperating with the Storm Worm authors. Among their most recent campaigns was the groups direct involvement in the malware campaigns at the Azerbaijanian Embassies in Pakistan and Hungary.

It gets even more interesting to see what they're up to in 2009, considering the fact that they have also parked domains used (174.129.241.185 and 174.129.244.106) in currently ongoing Facebook phishing campaign, which is switching themes from Match.com to Classmates.com :

The group has clearly diversified its activities, but continues relying on its well known portfolio of domains as a foundation.

Inside a Zeus Crimeware Developer's To-Do List

Every then and now I get asked a similar question in regard to crimeware kits - which is the latest version of a particular crimeware/web malware exploitation kit?

The short answer is - I don't know. And I don't know not because I'm a victim of an outdated situational awareness, but due to the fact that nowadays third-party developers are so actively tweaking it that coming up with a version number would be inaccurate from my perspective. Therefore, whenever I provide such a version number, I try to emphasize and provide practical examples of how the current decentralization of coding from the core authors to third-party developers and, of course, scammers brand jacking the Zeus brand, is making the answer a little bit more complex than it may seem at the first place.

For instance, cybercriminals themselves have been capitalizing on this situation during the last two quarters, by speculating with the version numbers and offering backdoored copies of non-existent Zeus releases, in a attempt to hijack their Zeus botnets at a later stage -- a practice that phishers have been taking advantage of for a while. Anyway, once I'm able to sort of cluster a particular third-party developer's persistence in tweaking the Zeus crimeware kit, an interesting picture emerges. For instance, a team member from a third-party developer of backend systems for botnets that came up with the built-in MP3 player in a Zeus release, is also directly involved in developing the backend system and GUI for the Chimera botnet which the British Broadcasting Corporation purchased last month.

Let's discuss the way the version number system in the Zeus crimeware, before we take a peek at a recent CHANGELOG, and a future TO-DO list from one of the third-party developers. Zeus version a.b.c.d means that change in A stands for a complete change in the bot, B stands for major changes that make previous bot versions incompatible, C stands for modifications and performance boosting, and D is a prophylactic change in order to avoid antivirus solutions from detecting it.

The Q&A applied in Zeus can be easily seen by taking a peek at some of the changes that took place in December, 2008 :

"Change 10.12.2008
- Documentation will no longer be available in a CHM format, instead in a plain-text format
- The bot is a now able to receive commands not only by using the send command function, but also during requests for files and logs changes
- Local data requests to the server and the configuration file can be encrypted with RC4 key depending on your choice
- In order to decrease the load on the server, a fully updated bot-to-server and server-to-bot communication protocol is introduced

Change 20.12.2008
- Small error fixed when sending reports
- The size of the report cannot exceed 550 characters
- Error fixed in the bot due to low timeout for sending POST requests resulting in dropping requests for log files bigger than 1 MB

Change 2.03.2009
- Changed the default cryptor routines
- Updated process of building the bot
- Optimized compressed of the binary
- Rewritten the process of assembling the configuration file
- Changed the MyMSQL tables
- Fixed fonts in the panel due to bogus displaying of characters
- Updated Geolocation database"

The following "To-Do" list, pretty similar to another one which I discussed last year (A Botnet Master's To-Do List). What's to come in the Zeus crimeware kit, at least courtesy of a sampled third-party developer? The following features have been in the works for several months now:

"- Compatibility with Windows Vista and Windows 7
- Improved WinAPI hooking
- Random generation of configuration files to avoid generic detection"
- Console-based builder
- Version supporing x86 processors
- Full IPv6 support
- Detailed statistics on antivirus software and firewalls installed on the infected machines"

The Zeus crimeware is not going away from the radar anytime soon, and the main reason for that is not the fact that its exclusive features outperform the ones in the Limbo crimeware and the Adrenalin crimeware, but due to the fact that Zeus has a much bigger fan base, and well established third-party community around it.

Bogus LinkedIn Profiles Redirect to Malware and Rogue Security Software

From the automatically registered bogus LinkedIn profiles promoting pharmaceuticals campaign in February, to January's malware campaign redirecting to malware Zlob variants and rogue security software, the malware gang behind both of these campaigns is once again showcasing its persistence.

It gets even more interesting when a direct connection between January's, this very latest campaign, and the most recent massive comment-spam attack at Digg.com, is established since the very same malware domains are participating in all of the campaigns (e.g funkytube .net)

Using a celebrities theme, all of these bogus accounts are linking to the same malware serving domains. The following central redirectors :

oymomahon .com/paqi-video/28.html
muse.100-celebrities .com/paqi-video/1.html
nahyu .org/xxxx/

are then redirecting to another set of fake codec domains :
xretrotube .com
globextubes .com

globerstube .com
spywareremover21 .com
antispyscanner13 .com
privacyscanner15 .com

to ultimately direct the visitor to the actual binaries:

loyaldown99 .com/codec/186.exe - detection rate
kol-development .com/viewtubesoftware.40012.exe - detection rate

Despite the fact that real-time/event-based blackhat search engine optimization is gaining popularity these days, blackhat SEO in its very nature relies on huge bogsus content farms, using a diverse theme-based set of content, usually generated in an automated fashion. Real-time blackhat SEO or standard volume-based blackhat SEO as a tactic of choice? Does it really matter given that from the perspective of tactical warfare, combining well proven tactics results in high click-through/infection rates for the campaigns in question.

Diverse Portfolio of Fake Security Software - Part Seventeen

The following are some of the currently active/about to go online rogue security software domains, and their associated payment gateways exposed in the spirit of the Diverse Portfolio of Fake Security Software series. During the past two months, an obvious migration of well known Russian Business Network customers continues taking place, with their portfolios of malicious campaigns currently parked several ISPs. zlkon.lv (DATORU EXPRESS SERVISS Ltd (AS12553 PCEXPRESS-AS) remaining the ISP of choice for the time being, in the context of rogue security software.

During March, a new type of scareware with elements of ransomware started circulating in the wild. It will be interesting to monitor whether it will become the de-facto standard for optimizing revenues out of rogue security software.
