Dissecting September's Twitter Scareware Campaign

UPDATE:  4 hours after notification, Twitter has suspended the remaining bogus accounts. Until the next time, when the reCAPTCHA recognition gets cost-effectively outsourced for automatic scareware-serving purposes.

Over the last couple of days, my Ukrainian "fan club" -- fan club in a sarcastic sense due to the love, more love, even more love and gratitude shown so far -- has once against started abusing Twitter by automatically generating bogus accounts tweeting scareware serving links by syndicating Twitter's trending topics.

This traffic acquisition tactic is in fact nothing new, and in the case of this Ukrainian cybercrime enterprise, is done "in between" the rest of their malicious activities. What's worth pointing out is that just like the most recent malvertising campaign at, the Ukrainian gang keeps using domains already in circulation within their blackhat SEO campaigns, making it fairly easy to establish connections between these and the ongoing Twitter campaign.

By the time Twitter suspends the automatically registered bogus accounts, on average, 70 to 80 tweets have been published per single account. Here's the most recent list of currently active Twitter accounts tweeting scareware links: /verina1238 /knab190 /zastrow994 /gustave12 /trautwein9975 /reinke341 /ordella509 /lysa380 /weinhold344 /wachsmann1541 /weishaupt917 /scheid1265 /fitz1677 /falkner425 /opel1409 /rasche1401 /schlecht1581 /verina1238 /perahta985

The accounts are relying on identical short URLs, with the following ones still active and in circulation: /lyby2r /nx39k8 /lyby2r /mnbfox /msjjv8 /mj5wju /mxg2vo /m656h7 /nffkly /bfnpv7 /bfnsa8 /bfny8e /bfnnu4 /bfnzkk 6af3fe 649be f6b7f5 0abe74 3AoRZ 3A5DD 3AUVc 3BZqa 3C4lU

The short URLs rely on several redirectors to finally land the end user on a scareware site, such as securityland .cn and imagination-1 .com:

securityland .cn - - Email: Parked on the same IP are also:
abclllab .com
0lenfo .com
ynoubfa .cn
protectinstructor .cn
immitations-all .net
1limbo .net

imagination-1 .com- - Email: Parked on the same IP are also:
bombas10 .com
graves111 .com
iriskas .com
yvicawo .cn

Where do we know the email from? Several of the scareware domains pushed in the ongoing U.S Federal Forms Themed Blackhat SEO Campaign have been registered using it, that very same blackhat SEO whose central redirector a-n-d-the .com/wtr/router.php - - and - - (hosted by Layered Technologies, Inc.) mimics the campaign structure of 2008's massive input validation abuse attack using iFrames, courtesy of the RBN and the very first scareware campaigns.

Moreover, the same email has been used to register two of the "phone-back" domains for the scareware pushed in the blackhat SEO campaign and the malvertising attack - windowsprotection-suite .net - Email: and securemysystem .net - Email:

The following scareware domains are not just used within the Twitter campaign, some of them have also been detected as part of blackhat SEO campaigns:

Sampled scareware also phones-back to mysecurityguru .cn - - Email:, the same phone-back domain was used in the scareware sampled from the malvertising attack, with the same email also belonging to a scareware domain (mainsecsys .info) listed in the Diverse Portfolio of Fake Security Software - Part Twenty Two for July.

The cybercrime powerhouse behind all these attacks, continues maintaining the largest market share of systematic Web 2.0 abuse, and that includes their involvement in the Koobface botnet.

The Ultimate Guide to Scareware Protection

Throughout the last two years, scareware (fake security software), quickly emerged as the single most profitable monetization strategy for cybercriminals to take advantage of. Due to the aggressive advertising practices applied by the cybercrime gangs, thousands of users fall victim to the scam on a daily basis, with the gangs themselves earning hundreds of thousands of dollars in the process.

This end user-friendly guide aims to educate the Internet user on what scareware is, the risks posed by installing it, how it looks like, its delivery channels, and most importantly, how to recognize, avoid and report it to the security community taking into consideration the fact that 99% of the current releases rely on social engineering tactics.

Koobface Botnet's Scareware Business Model

UPDATE1: TrendMicro just confirmed the ongoing double-layer monetization of Koobface. Meanwhile, the gang is rotating the scareware domains with new ones pushed by popup.php, followd by two recently updated Koobface components.

The new scareware domains kjremover .info; lrxsoft .info - - Email: actually download it from the well known q2bf0fzvjb5ca .cn portfolio, which phones back to the same domains listed previously, with only a slight change in the filename - urodinam .net/8732489273.php. The generic detection rate for the updated components ( /bin/get.exe; /bin/v2webserver.exe) with get.exe phoning back to a domain parked at the takedown-proof, China-based, in particular gdehochesh .com/adm/index.php.
Just like Conficker, the Koobface botnet is no stranger to the scareware business model and the potential for monetization of the hundreds of thousands of infected hosts.

However, changes made in the campaign structure of the Koobface botnet during the last couple of days, indicate that the Koobface gang has embedded a pop-up at each and every host that's automatically rotation different scareware brands. They're now officially monetizing the botnet using a scareware business model.

Let's analyze the latest changes introduced by the Koobface gang over the last couple of days and emphasize on the monetization tactics introduced by the gang.

Next to insulting, showing gratitude, the Koobface gang also has a (black) sense of humor - within one of the directories at the takedown-proof command and control used by the gang in China (; at in particular) they've left the following message "2008 ali baba and 40, LLC". Ali Baba and the Forty Thieves is a 1944 film based on the original Ali Baba character.

Compared to previous campaigns relying on centralized command and control and redirection points -- making them easy to shut down -- the ongoing Facebook campaigns are dynamically redirecting to IPs within the Koobface network, which combined with their use of compromised legitimate sites is supposed to make the take down of their campaigns a bit more time consuming.

That's, of course, not the case since undermining their monetization approaches undermines the monetary value of their campaigns, which is what they're after this time. The Koobface gang has now embedded a single line within each and every infected host used in the campaign, in order to not only attempt to infect new visitors with the Koobface malware itself, but to also trick them into installing the scareware which is rotated as usual.

dangerWindAdr = popup.php loads on each and every Facebook spoof page part of the botnet and is then redirecting the most popular scareware template, the My computer Online Scan.

The first scareware domain used in the last 48 ryacleaner .info/hitin.php?affid=02979 ( parked there as also eljupdate .info Email: and dercleaner .info Email: was serving setup.exe which is downloading the actual scareware executable from mt3pvkfmpi7de .cn/get.php?id=02979 (

What's so special about this domain? It was last profiled in the A Diverse Portfolio of Fake Security Software - Part Twenty Three with the entire portfolio of .cn domains parked at the same IP registered under the same email -

The second scareware domain pushed by the Koobface during the last 24 hours, gotrioscan .com/?uid=13301 - - redirects to plazec .info/22/?uid=13301 - - Email: where the scareware is served. Parked at the same IP is the rest of thescareware domains portfolio pushed by Koobface:

What do these two scareware executables have in common? Its the phone back locations that the Koobface gang is using, reveling its participation in a scareware affiliate network called Crusade Affiliates.

The first phone back location /dfgsdfsdf .php - adds a .bat file which would attempt to obtain mshta.exe from .php?stime=1253063118 on hourly basis. The second phone back location is the Crusade Affiliates network that shares revenue with the Koobface gang whenever a scareware pushed by the gang is purchased - crusade-affiliates .com/install.php?id=02979 -

The third phone back location is a direct download attempt of FraudTool.Win32.SecretService; RogueAntiSpyware.PrivacyCenter.AJ from 0ni9o1s3feu60 .cn/u4.exe - It's pretty evident that the Koobface botnet is now relying on multiple layers of monetization approaches.

The Koobface gang has been pretty during the last couple of days. The following list of Koobface malware spreading domains are in circulation across social networking sites since the last 48 hours, consisting of a combination of purely malicious and compromised legitimate sites:

Ukrainian "Fan Club" Features Malvertisement at

If my Ukrainian "fan club" can exploit weaknesses in the online ad publishing model for scareware serving purposes, anyone else could.

Yesterday, the posted a note to readers, confirming that a malvertisement campaign somehow made on their web site, resulting in the automatic exposure of users to scareware:

"Some readers have reported seeing a pop-up box warning them about a virus and directing them to a site that claims to offer antivirus software. We believe this was generated by an unauthorized advertisement and are working to prevent the problem from recurring. If you see such a warning, we suggest that you not click on it. Instead, quit and restart your Web browser."

Who's behind this malvertising campaign? Let the data speak for itself.

According to a published assessment of the campaign, the redirector and scareware domains involved in the malvertising incident are also in circulating in blackhat SEO campaigns courtesy of the Ukrainian gang (the post is updated daily with the very latest redirector and scareware domains pushed by the gang).

In the malvertising attacks, that's sex-and-the-city .cn (parked at where the rest of their redirectors are) acting as redirector leading to the protection-check07 .com scareware, parked on the very same IPs (;; like the rest of the new scareware domains systematically updated once or twice during a 24 hours period, again courtesy of the "fan club".

The last sample in circulation, phones back to windowsprotection-suite .net - Email:; mysecurityguru .cn - - Email: also maintains secure-pro .cn; and to securemysystem .net - Email:

The malvertisement assessment also highlights tradenton .com - - Email: as the domain used in the ad rotation. Interestingly, related malvertisement domains managed by the same gang, have already been reported in related malvertising attacks, are also parked on the same IP:
relunas .com - Email:
kennedales .com - Email:
harlingens .com - Email:
newadsresults .com - Email:
waveadvert .com - Email:

As always, what would originally seem as an isolated incident orchestrated by yet to be analyzed cybecrime gang, is in fact a great example of underground multitasking in action through the convergence of different attack tactics, courtesy of a single cybercrime enterprise.

News Items Themed Blackhat SEO Campaign Still Active

According to a blog post at PandaLabs, a massive and very persistent blackhat SEO campaign exclusively hijacking "hot BBC and CNN news" related keywords has once again popped-up on their radars. The campaign itself has been active since April, when I last analyzed it.

What has changed?

Instead of relying on purely malicious domains, the Ukrainian fan club, the one with the Koobface connection, remains the most active blackhat SEO group on the Web, and due to the quality of the historical OSINT making it possible to detect their activity -- practice which prompts them to insult back -- they're also starting to put efforts into making it look like it's another group.

However, knowing  the tools and tactics that they use, next to evident efficiency-centered mentality, they continue leaving minor leads that make it possible to establish a direct relationship between the group, the Koobface worm and the majority of blackhat SEO campaigns launched during the last couple of months across the entire Web.

The "News Items" themed blackhat SEO campaign is also serving scareware from the domains already participating in the U.S Federal Forms themed blackhat SEO campaign, what's new is the typical dynamic change of the redirectors in place.

Let's dissect a sample campaign currently parked at Once the http referrer checks are met, bernie-madoff.coolinc .info/fox-25-news.html executes the campaign through a static images/ads.js located on all of the subdomains participating in campaign (bernie-madoff.coolinc .info/images/ads.js; eenadu-epaper.hmsite .net/images/ads.js) with generic detection triggered only by Sophos as Mal/ObfJS-CI.

Through a series of redirectors - usanews2009 .com/index.php - - Email:; newscnn2009 .com/index.php - - Email:; cnnnews2009 .com/index.php - - EMail:; the user is redirected to the scareware domain through justintimberlakestream .com/?pid=95&sid=4e6ffe -; Email:

The scareware itself (phones back to worldrolemodeling .com/?b=1s1 - is dynamically served through; and with an diverse portfolio of fake security software domains parked there.

In between the central redirectors, counters from known domains affiliated with the Ukrainian fan club are also embedded as iFrames - sexualporno .ru/admin/red/counter2.html (; Email: leading to sexualporno .ru/admin/red/mwcounter.html. Parked on are related domains that were once using the ddanchev-suck-my-dick.php redirection, such as sexerotika2009 .ru; celki2009 .ru; seximalinki .ru and videoxporno .ru, as well as the de-facto counter used by the gang -

Does this admin/red directory structure ring a bell? But, of course. In fact the ddanchev-suck-my-dick redirectors originally introduced by the Ukrainian fan club are still in circulation - for instance not only is videoxporno .ru/admin/red/ddanchev-suck-my-dick.php (parked at the very same still active, but the gang has pushed an update to all of their campaigns, once again establishing a direct connection between previous ones and the ongoing "News Items" themed one.

The ddanchev-suck-my-dick.php file has a similar Mac, Firefox and Chrome check just like the U.S federal forms themed campaign, and the original "Hot News" themed campaigns - if (navigator.appVersion.indexOf("Mac")!=-1) window.location="";[. The script also includes a central iFrame from the now known malicious coolinf .info - dash-store.coolinc .info/images/levittpedofil.html which redirects to 1008.myhome .tv/888.php, popoz.wo .tc/p/go.php?sid=4 and 1009.wo .tc/8/ss.php to finally load the now known justintimberlakestream .com/?pid=42&sid=8f68b5.

The bottom line - the Ukrainian "fan club" is a very decent example of a multitasking cybecrime enterprise that is not only systematically abusing all the major Web 2.0 services, but is also directly involved with the Koobface botnet.

Monitoring of their campaigns, and take down actions would continue.

SMS Ransomware Displays Persistent Inline Ads

SMS-based micro-payments are clearly becoming the monetization channel of choice for the majority of cybercriminals engaging in ransomware campaigns. The logic behind this emerging trend is fairly simple, and as everything else in the cybercrime underground these days, it has to do with efficiency.

Compared to micro-payments, the 2008's monetization channel used by GPcode in terms of E-gold and Liberty Reserve accounts communicated over email -- with cases where the gang wasn't even bothering to respond to infected victims looking for ways to pay the ransom -- looks like a time-consuming and largely inefficient way to "interact" with the victims.

Another recently released SMS-based ransomware showing persistent ads within the browser sessions of infected victims, and demanding a premium-rate SMS for removal, is the very latest indication of the micro-payment monetization channel trend.

The DIY ransomware is offered for sale at $100, with the typical "value-added" services in the form of managed undetected binaries through crypting. Since the command and control interface is web based (php+mysql), the author is actively experimenting with new features such as scheduled appearing of the ads, inventory of banners and affiliate program links, and the ability to use multiple SMS numbers next to multiple unlocking codes.

Are the currently active ransomware "vendors" trendsetters or are they still in experimental mode?

The business model of SMS-based ransomware is clearly lucrative, especially in situations where cybercriminals are known to combine two or three different monetization tactics. However, compared to the high profit-margins which cybecriminals earn through the scareware business model, SMS-based ransomware remains a developing market segment.
