Crimeware in the Middle - Adrenalin

What is Adrenalin? Adrenalin is an alternative to the Zeus crimeware kit that never actually managed to scale the way Zeus did. Following recently leaked copies of what is originally costing a hefty $3000, crimeware kit Adrenalin, it's time to profile the kit, discuss its key differentiation factors from Zeus, and emphasize on why despite the fact that it leaked, the kit is not going to take any of Zeus-es market share. At least not in its current form.

In the spirit of the emerging copycat web malware exploitation kits, Adrenalin too, isn't coded from scratch, but appears that -- at least according to cybercriminals questioning its authenticity on their way to secure a bargain deal when purchasing it -- Adrenalin is using portions of Corpse's original A-311 release.

Adrenalin's description and features :
"Injections system - inserting html / javascript code in the page / files / javascript or substitution of one code by another injection occurs in the stream mode, ie the modified page is loaded at once!
(not as in the other BHO based trojans with insertions only after the full load the page (causing javascript problems) or limiting the impact (if for instance the user is on a mobile device connection). In our implementation, all works quickly and efficiently!

- The collection of pieces of text from the html pages, as one of the modes of operation injector (balance, etc ..)

- Ftp grabbing - sniffer handles traffic and rip out from access to FTP. All of this is going in an easy to read and process the form

- Collector of certificates. Pulling out of all installed certificates including attempts to commit, and certificates that are marked as uncrackable. Certificates neatly stored for each individual bot.

- Page redirector. allows you to replace a page or separate framing in the network. everything is done completely unnoticed. substitution of the content occurs in the interior windsurfing, and even then the browser and any special lotion can be confident that is what you want.

- Domain redirector. forwards all requests from the original site on the fake. address bar, and all references point to the original course can also be used to block access to certain sites

- Universal form grabbing puller forms, can strip the data from the virtual keyboard these forms can rip off, even with not fully loaded pages. As distinguished from the other crimeware kits working through the tracking of users clicking buttons / links it intercepts the data has already been formed, which can be seen in the log. Data can be collected all the running, and keyword (filter)
to delete the logs; noise over debris to chat and not necessary for the work sites.

All data are transmitted in encrypted form, which is important to bypass the protection, like for instance ZoneAlarm's ID Lock. Undoubted advantage is also that the logs are sent instantly - in parallel with the data sent to the original site. No need to worry that the victim will go into an offline and accumulated locally log form grabbing are not able to send.

- Screenshots at the address
- TAN grabbing. The technology allows to effectively collect workers TANs
- Periodic cleaning of cookies/flashcookie.
- Grabbing around-the-forms words (without adjustment - Adrenalin defines its own algorithm that it must be collected. algorithm Improved!)
- The collection of passwords,  for instance Protected Storage (IE auto complete, protected sites, outlook)
- Classic keylogger
- Cleaning system from BHO trojans, advertising panels and other debris. As is well known - are less vulnerable machines, and want to put on something more. Cleaning system greatly increases the chances of survival
- Anti-Anti Rootkit mechanisms
- Work on the system without the EXE file
- User-friendly format logs! Forget the piles of files stupid!
- Socks4 / 5 + http (s) proxy server enabled on the infected host
- Shell + Backshell enabled on the infected host
- Socks admin
- Management of each bot individually, or simultaneously (Downloading files, updating settings, etc.)
- Requires PHP on the web based command and control host
- Ability to output commands (including downloads), taking into account the country's bot (function as a resident loader statistically for programs) - and other small pleasures"

Without the web injection and the TAN grabbing ability, Adrenalin is your typical malware kit, whose only differentiation factor would have been the customer support in the form of the managed undetected malware binaries that naturally comes with it. However, it's TAN grabbing ability, proprietary collection of data "around the forms", stripping content from virtual keyboards and automatic certificates collection on per host basis, and its ability to clean the system from competing BHO-based trojans, make it special.

How do you actually measure the popularity of crimeware kit? Based on the the market share of the crime kit, or based on another benchmark? It's all a matter a perspective and a quantitative/qualitative approach. For instance, I can easily argue that if the very same community was build around Adrenalin the way it was built around Zeus making the original Zeus release looks like an amateur-ish release, perhaps Adrenalin would have scaled pretty fast. Some of the community improvements include :

- Modified Zeus Crimeware Kit Comes With Built-in MP3 Player
- Modified Zeus Crimeware Kit Gets a Performance Boost
- Zeus Crimeware Kit Gets a Carding Layout

For the time being, the innovation or user-friendly features boosting the popularity of Zeus come from the third-party coders improving the original Zeus release. Moreover, not only are they improving it, they're also looking for vulnerabilities within the different releases, and actually finding some. What does this mean? It means that we have clear evidence of crimeware monoculture, with a single kit maintaining the largest market share.

With the cybercrime ecosystem clearly embracing the outsourcing concept for a while, it shouldn't come as a surprise, that botnets running the Zeus crimeware are offered for rent at such cheap rates that purchasing the kit and putting efforts into aggregating the botnet may seem a pointless endeavor in the eyes of a prospective cybercriminal, even an experienced one interested in milking inexperienced cybercriminals not knowing the real value of what they're doing.

Moreover, speaking of monetization, the attached screenshots represent a very decent example of monetizing the reconaissance process of E-banking authentication that cybercriminals or vendors of crimeware services undertake in order to come up with the modules targeting the financial institutions of a particular country. Is this monetization just "monetization of what used to be a commodity good/service" as usual taking into consideration this overall trend, or perhaps there's another reason for monetizing snapshots of E-banking authentication activities in order to later on achieve efficiency in the process of abusing them? But of course there is, and in that case it's the fact that no matter that a potential cybercriminal has obtained access to a crimeware kit, its database of injects is outdated and therefore a new one has to be either built or purchased.

With Adrenalin now leaked to the general script kiddies and wannabe cybercriminals, it's only a matter of time until a community is build around it, one that would inevitably increase is popularity and prompt others to introduce new features within the kit.

Copycat Web Malware Exploitation Kits Are Still Faddish

The oversupply of web malware exploitation kits is in fact

The Template-ization of Malware Serving Sites - Part Two

The growing use of "visual social engineering" in the form of legitimately looking codecs, flash player error screens, adult web sites, and YouTube windows in order to forward the infection process to the end use himself, is the direct result of the ongoing template-ization of malware serving sites. This standardizing is all about achieving efficiency, in this case, coming up with high-quality and legitimately looking templates impersonating the average Internet user by enjoying the clean reputation of the impersonated service in question.

The attached screenshot of  very latest DIY windows media player with pretty straightforward instructions on how to modify the timing of the "missing codec" pop-up, is a great example of how cybercriminals rarely value the intellectual property of their fellow colleagues. The DIY template has in fact been ripped-off from a competing affiliate network participant (currently active xxxporn-tube .com/123/2/FFFFFF/3127/TestCodec/Best), its images hosted at ImageShack, and the codec released for everyone in the ecosystem to use -- and so they will.

Interestingly, within the mirrored copy now tweaked and distributed for free using free image hosting services as infrastructure provider for the layout, there are also leftovers from the original campaign template that they mirrored - which ultimately leads us to DATORU EXPRESS SERVISS Ltd (AS12553 PCEXPRESS-AS) or zlkon.lv In the wake of UkrTeleGroup Ltd's demise -- don't pop the corks just yet since the revenues they've been generating for the past several years will make it much less painful -- a significant number of UkrTeleGroup customer, of course under domains, have been generating quite some malicious activity at zlkon.lv for a while.

Poisoned Search Queries at Google Video Serving Malware

UPDATE: A recently published article at the Register by John Leyden incorrectly states that "researchers at Trend Micro discovered that around 400,000 queries returning malicious results that lead to a single redirection point" wherease the researchers in question went public with the attack data on the 27th of January, and then again on the 28th of January.

This isn't the first time the Register shows an oudated siatuational awareness, following the two month-old coverage of a proprietary email and personal information harvesting tool, which I extensively covered in between receiving comments from one of the affected sites.

A blackhat SEO-ers group that's been generating bogus link farms ultimately serving malware to their visitors during the past couple of months, has recently started poisoning Google Video search queries and redirecting the traffic to a fake flash player using the PornTube template. (The Template-ization of Malware Serving Sites). Approximately 400,000+ bogus video titles have already been crawled by Google Video.

Instead of sticking to a proven traffic acquisition tactic in the face of adult videos, the campaigns are in fact syndicating the titles of legitimate YouTube videos in order to populate the search results. What's also worth pointing out that is that once they start duplicating the content -- like they're doing with specific titles -- based on their 21 bogus publisher domains, they can easily hijack each and every of the first 21 results for a particular video. The fake flash player redirection is served only when the visitor is coming from Google Video, if he or a researcher isn't based on a simple http referer check, a legitimate YouTube video is served.

Upon clicking on the video from any of their publisher domains, the user is taken to porncowboys .net/continue.php (94.247.2.34) then forwarded do xfucked .org/video.php?genre=babes&id=7375 (94.247.2.34) to have the binary served at trackgame .net/download/FlashPlayer.v3.181.exe and qazextra .com/download/FlashPlayer.v3.181.exe. Detection rate for the flash player.

The malware publisher domains crawled by Google Video redirecting to the bogus flash player :
nudistxxx .net - 22,000 bogus video titles
realsexygirls .net - 21,000 bogus video titles
trulysexy .net - 27,100 bogus video titles
madsexygirls .net - 18,900 bogus video titles
mypornoplace .net - 25,700 bogus video titles
hotcasinoxxx .net - 28,900 bogus video titles
hotgirlstube .net - 37,900 bogus video titles
xgirlplayground .com - 50,600 bogus video titles
puresextube .net - 20,700 bogus video titles
xxxtube4u .com - 11,400 bogus video titles
sexygirlstube .net - 63,100 bogus video titles
xporntube .org - 12,800 bogus video titles
xxxgirls .name - 33,500 bogus video titles
girlyvideos .net - 37,500 bogus video titles
mytubecentral .net - 38,900 bogus video titles
puresextube .net - 20,700 bogus video titles
teencamtube .com - 18,400 bogus video titles
celebtube .org - 41,100 bogus video titles
truexx .com - 16,900 bogus video titles
hottesttube .net - 28,100 bogus video titles
hotgirlsvids .net - 27,200 bogus video titles
watch-music-videos .net - 14,900 bogus video titles
marketvids .net - 29,900 bogus video titles
gamingvids .net - 7,930 bogus video titles
hentaixxx .info - 25,500 bogus video titles

The campaign is currently in a cover-up phrase since discussing it yesterday and notifying Google with all the details. But the potential for abuse remains there. Timeliness vs comphrenesiveness of a malware campaign?

Following this example of comprehensivess, take into consideration the timeliness in the face of October 2008's campaign when hot Google Trends keywords were automatically syndicated in order to hijack search traffic which was then redirected to several hundred automatically registered Windows Live blogs whose high pagerank made it possible for the blogs to appear within the first 5 results.

Embassy of India in Spain Serving Malware

The very latest addition to the "embassies serving malware" series is the Indian Embassy in Spain/Embajada de la India en España (embajadaindia.com) which is currently iFrame-ED -- original infection seems to have taken place two weeks ago -- with three well known malicious domains.

Interestingly, the malicious attackers centralized the campaign by parking the three iFrames at the same IP, and since no efforts are put into diversifying the hosting locations, two of them have already been suspended. Let's dissect the third, and the only currently active one. iFrames embedded at the embassy's site:
msn-analytics .net/count.php?o=2
pinoc .org/count.php?o=2
wsxhost .net/count.php?o=2

wsxhost .net/count.php?o=2 (202.73.57.6) redirects to 202.73.57.6 /mito/?t=2 and then to 202.73.57.6 /mito/?h=2e where the binary is served, a compete analysis of which has already been published. The rest of the malicious domains -- registered to palfreycrossvw@gmail.com -- parked at mito's IP appear to have been participating in iFrame campaigns since August, 2008 :

google-analyze .cn
yahoo-analytics .net
google-analyze .org
qwehost .com
zxchost .com
odile-marco .com
edcomparison .com
fuadrenal .com
rx-white .com


As always, the embassy is iFramed "in between" the rest of the remotely injectable sites part of their campaigns.

Exposing a Fraudulent Google AdWords Scheme

UPDATE: Conduit's Director of Strategic Marketing Hai Habot contacted me in regard to the campaign. Comment published at the bottom of the post.

Despite my personal reservations towards the use of Google sponsored ads as an emerging traffic acquisition tactic on behalf of scammers and cybercriminals -- blackhat SEO is getting more sophisticated -- Google sponsored ads are whatsoever still taken into consideration.

The fraudulent AdWords scheme that I'll discuss in this post, is an example of a Dominican scammer (ayuda@shareware.pro; Sms Telecom LLC, Roseau, St. George (00152) Dominica Tel: +117674400530) who's hijacking search queries for popular software applications, taking advantage of geolocation and http referer checks, in order to deliver a customized toolbar while earning revenue part of the Conduit Rewards Program.

Naturally, the traffic acquisition tactic and the brandjacking of legitimate software are against the rules of both Google's, and Conduit's terms of use. Interestingly, out of all the adware-ish toolbars and affiliate based networks out there, he's chosen to participate in an affiliate network without a flat rate on per toolbar installation basis. Despite the efforts put into the typosquatting, the descriptive binaries on a country basis, and the localization of the sites in several different languages, he's failing to monetize the scam in the way he could possibly do compared to "fellow colleagues" of his.

Brandjacked software domains part of the AdWords campaign :
adobe-reader-co .com
adware-co .com
flash-player-co .com
paint-shop-pro .com

paint-net-co .com
download-acelerator .com
windownloadweb .com
xp-codecpack-co .com


The AdWords campaigns are spread across different local Google sites, and are targeting a particular local demographic only. Moreover, if the end user isn't coming from a sponsored ad, the download link on each and every of the participating sites is linking to the official site of the brandjacked software, and if he's coming from where he's supposed to be coming the software bundle including the revenue-generating toolbar is served in the following way :

firefox-co .com/downloads/installer-5-firefox-uk.exe
winamp-co .com/downloads/installer-37-winamp-uk.exe
winamp-co .com/downloads/installer-37-winamp-nl.exe
zone-alarm-co .com/downloads/installer-18-zonealarm-nl.exe
servicepack-co .com/downloads/installer-14-service-pack-3-uk.exe
divx-co .com/downloads/installer-25-divx-uk.exe

Upon installation the toolbar generates revenue for the campaigner, and given the fact that a single DIY toolbar can be associated with a single rewards account, the campaigner is also maintaining a modest portfolio of toolbars. For instance :

peer2peerne.media-toolbar.com - UserID=UN20090120111936062
peer2peeren.media-toolbar.com - UserID =598F9353-BD10-47B9-8B40-29B33AD7A3E4

The bottom line is that despite the fact that the campaigner is acquiring lots of traffic through the brandjacking, and is definitely breaking even based on the number of toolbars installed, he's failing to monetize the fraud scheme, at least for the time being.

UPDATE: Hai Habot's comments - "The information you have provided will help us track the publisher and I will personally see that our compliance team looks into it ASAP.
 

As you may know, Conduit does not have full control over the promotional activity of the publisher (i.e. his fraudulent use of Google AdWords or any other usage of third party ads or links) however, the activity described in your post is clearly in violation of our terms of use (section V of the Conduit Publisher Agreement) and our compliance team can take different measures against this publisher including the removal of the toolbar from our platform.

The Conduit Rewards program is not a standard affiliate network. It offers incentives to publishers based on their toolbar’s long term performance. I didn’t look into the stats of this specific publisher yet but I can assure you that such spam traffic would generate very little (if any) rewards. In any case – we will make sure that the rewards account of this publisher will be disabled until this compliance issue is resolved."
