I See Alive IFRAMEs Everywhere - Part Two

The never ending IFRAME-ing of relatively popular or niche domains whose popularity is attracting loyal and well segmented audience, never ends. Which leads us to part two of this series uncovering such domains and tracing back the malicious campaign to the very end of it. Some of these are still IFRAME-ed, others cleaned the IFRAMEs despite Google's warning indicating they're still harmful, the point is that all of these are connected.

Affected sites :

Epilepsie France - epilepsie-france.org
Iran Art News - iranartnews.com
The Media Women Forum - yfmf.org
Le Bowling en France - bowling-france.fr
The Hong Kong Physiotherapists Union - hkpu.org
The Wireless LAN Community - wlan.org
The First HELLENIC Linux Distribution - zeuslinux.gr

The entire campaign is orbiting around pornopervoi.com, which was last responding to 81.177.3.225, an IP that's also known to be hosting a fake bank (weiterweg-intl.com) according to Artists Against 419. Within the domain, there were small files loading a second IFRAME. For instance, pornopervoi.com/u.php leads to 88.255.94.246/freehost1/georg/index.php?id=0290 (WebAttacker), the same campaign is also active at 81.29.241.238/freehost1/georg/index.php?id=0290, these try to drop the following :

88.255.94.246/freehost1/chris0039/lu/dm_0039.exe
81.29.241.238/freehost1/chris0031/lu/dm_0031.exe

An Apophis C&C panel was located in this ecosystem as well. Among the other files at pornopervoi.com, are pornopervoi.com/i.php where we're redirected to the second one spelredeadread.com/in.php?adv=678. Even more interesting, energy.org.ru a Web hosting provider is also embedded with pornopervoi.com/m.php again forwarding to spelredeadread.com. To further expand this ecosystem, yfmf.org the Media Women Forum is also IFRAME-ed with a link pointing to pornopervoi.com/m.php. Another site that's also pointing to pornopervoi.com/m.php is the Hong Kong Physiotherapists Union hkpu.org. Two more sites serving malware, namely wlan.org, the Wireless LAN Community also pointing to pornopervoi.com/m.php, and zeuslinux.gr, The First HELLENIC Linux Distribution.

Who's behind this malware embedded attack? It's the ongoing consolidation between defacers, malware authors, and blackhat SEO-ers using the infamous infrastructure of the RBN.

But Malware is Prone to be Profitable

Read this a couple of times, than read it several more times, and repeat. It's usually "powerful stuff" that prompts such confusing descriptions of what sound like defense in-depth at one point, and a combination of intergalactic security statements in respect to the "massive amounts of computing power required" to solve the "security problem" at another. Stop predicting weather and assessing the impact of global warming, and command the supercomputers to figure our the scientific mysteries behind common insecurities :

"Even if we can't produce effective network security, we can at least make it more difficult and therefore expensive to attack a network by adopting some of the hacker's own techniques. He favors randomizing the use of a number of techniques for filtering content, so that individual malware vectors will sporadically stop working. By changing the challenge involved in compromising systems, the whole malware economy is changed. Stolfo also took a positively Darwinian view of how much change was needed, suggesting that security only had to be good enough to make someone else's system look like a more economical target. Overall, the talks were pretty depressing, given that the operating systems and software we rely on will probably never be truly secure. The process of blocking malware that takes advantage of this insecurity appears to be entering the realm where true security has become one of those problems that requires massive amounts of computing power and an inordinate amount of time."

The operating systems and the software we use can be truly secure, but will be useless compared to the currently insecure, but useful ones we're using. Now here's a great and straight to the point article, that's segmenting the possible uses of a host that's already been compromised, a great example of how innovations in terms of improved Internet connectivity, increased CPU power, and flexibility of online payments both steamline progress, and contribute to the growth of the underground.

Beat malware by doing what malware authors do? Sounds great. Malware authors outsource, do it too. Malware authors embraced the on demand SCM concept, embrace it too. Malware authors consolidate with stronger strategic partners, and acquire the weaker ones by providing them with DIY malware creation tools in order for them to make the headlines at a later stage, consolidate too. Malware authors keep it simple the stupids, you fight back with rocket science theoretical models and shift the focus from the pragmatic reality just the way it is - consolidation, outsourcing, shift towards a service based economy, quality and assurance of the malware releases, malicious economies of scale in the form of malware exploitating kits, ones it's getting hard to keep track of these days.

At the bottom line, how to solve the "malware problem"? It all depends on who you're solving it for. Long live marginal thinking.

Exposing the Russian Business Network

It was about time someone comes up with an in-depth study summarizing all of the Russian Business Network's activities, as for me personally, 2007 is the year when bloggers demonstrated what wisdom of the crowds really means, by putting each and every piece of the puzzle to come up with the complete picture, one the whole world benefits from. A highly recommened account into the RBN's activities courtesy of David Bizeul's "Russian Business Network study" :

"It’s interesting to observe that many recent cyber crime troubles are relating to Russia. This observation is obviously a simple shortening. Indeed nothing seems to link to Russia at first sight, it’s a nasty country for sending spam but many are worst, Russia is only the 8th top spam country. We need to dig deeper to identify that cyber crime is originating mostly from Russian dark zones. In a digital world, those dark zones exist where the Internet becomes invisible and it’s used for collecting phishing sites credentials, for distributing drive by download exploits, for collecting malware stolen data, etc. It’s a considerable black market as it has been revealed in this paper. A lot of information can be available over the web on Russian malicious activities and precisely on the way RBN (Russian Business Network) plays a major role in these cases."

What contributed to such a well coordinated exposure of the RBN during the last two quarters at the bottom line? It's not just security researchers exchanging info behind the curtains, but mostly due to RBN's customers confidence in RBN's ability to remain online. And while remaining online has never been a problem for the RBN, until recently when DIY IP blocking rulesets were available for the world to use, they undermined their abilities to remain undetected. In fact, I was about start a contest asking anyone who can come up with a IP with a clean reputation within the RBN's main netblock right before it dissapeared, and would have been suprised if someone managed to find one.

The RBN doesn't just makes mistakes when its customers embedd malware hosting and live exploit URLs on each and every malware and high-profile attack during the year, it simply doesn't care in covering its tracks and so doesn't their customers as well. RBN's second biggest mistake for receiving so much attention is their laziness which comes in the form of over 100 pieces of malware hosted on a single IP, without actually bothering to take care of their directory listing permissions, allowing my neatly crafred OSINT gathering techniques to come up with yet proof of a common belief into their practice of laziness. Moreover, the KISS strategy that I often relate to the successful malicious economies of scale that malware authors achieve due to DIY malware kits using outdated exploits compared to bothering to purchase zero day ones, didn't work for the RBN. Remember that each and every of the several Storm Worm related IPs that I covered once were returning fake suspended account notices in a typical KISS strategy, while the live exploit URLs and the actual binaries were still active within the domains.

This isn't exactly what you would expect from what's turning into a case study on conversational marketing, or perhaps how conversational marketing provokes the wisdom of crowds effect to materialize, so that the entire community benefits from each and everyone's contribution - in this case exposing the RBN.

How would the RBN change its practices in the upcoming future given all the publicity it received as of recently? They will simply stop benefing from the easy of management of their old centralized infrastructure, and will segment the network into smaller pieces, but while still providing services to their old customers, they're easy to traceback, and to sum up this post in one sentence - the Russian Business Network is alive, and is providing the same services to the same customers, including malware and live exploits hosting URLs under several different netblocks.

It's also great to note that David's been keeping track of my research into the RBN's activities. Go through the study and find out more about the RBN practices.

The State of Typosquatting - 2007

The recently released "What’s In A Name: The State of Typo-Squatting 2007" is a very in-depth and well segmented study into the topic, you should consider going through :

Introduction
Typo- and Cyber-squatting on the rise
Key Findings
Methodology
Rankings by Category
Sample site: McAfee.com
The Economics of Typo-Squatting: Why it Works
What is driving the increase in typo-squatting
The decline in adult content on typo-squatters
Discussion of our methodology
Defining Typo-Squatting
Other Methods for Combating Typo-Squatting
Conclusions
Complete Results

Is it just me using bookmarks and only risking to fall victim into a pharming attack, compared to manually typing and mistyping an URL? My point is that coming across several articles emphasizing how important typing the right URLs is, I think they've missed an important point which is that typosquatting by itself isn't that big of a security threat, but in a combination of tactics it becomes such. There's no chance you will ever mistype an URL such as paypal-comlwebscrc-login-run.com, a typosquatted domain like the ones I covered in September, since these ones come in as phishing emails hosting a Rock Phish kit, namely they turn into threats when combined with other tactics. Blackhat SEO is another such tactic. The type of buy-cheap-iphones.com always aim to trick search engines into positioning them among the first 20 results, and they often succeed until a search engine figures out it's a blackhat SEO spam and removes it from the index.

Here's an example of such combination of tactics, use-iphone.com for instance was spammed according McAfee, the folks behind the study. What's was use-iphone.com all about? Icepack kit in action - use-iphone.com/ice-pack/index.php.

A Botnet of Infected Terrorists?

Redefining malware to minimize the negative public outbreak by renaming it to Remote Forensic Software, now that's a evil marketing department's positioning strategy in action. I've already discussed how inpractical the utopian central planning of a security industry is, and while you're limiting the access to the tools who may help someone unethically pen testing an internal asset, you're also limiting the possibility for the discovery of such vulnerable asset - basically a false feeling of security, you don't touch it, it doesn't move, until of course someone else outside your controlled environment comes across it, the way they will sooner or later since it's an open network, one you benefit from, but cannot fully control.

Australian law enforcement have been using spyware for a while, and Austria following Germany's interest into the concept is getting involved too:

"Germany is hiring software specialists to design "white-hat" viruses that could infiltrate terrorists' computers and help police detect upcoming attacks, an Interior Ministry spokeswoman in Berlin confirmed Saturday. The government is still drafting legislation to permit snooping via the internet under judicial control, but has decided there is no time to lose in developing the "remote forensic software." The ministry said the BKA federal police had been instructed to resume the development and hire two specialists."

Are cyber criminals or bureaucrats the industry's top performer? In November, 2008, we'll be discussing how come so much money were spend to develop the malware, given the lack of any ROI out of this idea during the entire period, whereas DIY malware tools are not just a commodity, but also freely available for a law enforcement to use. Moreover, emailing malware is so old-fashioned and noise generating, that even the average Internet users knows "not to click on those email attachments sent from unknown source". A far more pragmatic approach would be to embedd the malware on sites suspected of evangelizing terrorism, or radicalizing their audiences, by doing so you'll end up with a larger infected sample, and eventually someone, let's say 1 out of 10,000 infected will turn out to be a terrorist, by whatever definition you're referring to in the case. Even more pragmatic, by requesting a botnet on demand, and requiring the botnet master to tailor your purchase by providing you with infected hosts in Germany whose browser language, and default fonts used are Arabic, you will not just save money, but will increase the probability of coming across a stereotyped terrorist, by outsourcing the infecting stage to those who excell at it.

Excluding the sarcasm, it's your money that go for funding of such initiatives who basically "shoot into the dark" to see if they can hit someone. Even if they manage to infect someone, more staff will be required to monitor the collected data, which means more money will go into this, ending up with an entire department monitoring wishful thinking and thought crime. Geheime Staatspolizei anyone?

If you really want access to real-time early warning threat intell for possible threats, monitor the public cyber jihadist communities don't come up with new ones to use them as honeypots for cyber jihadists, identify local residents, evaluate their state of radicalization and attitudes towards standard terrorist ideas, prioritize, and take action if necessary.

Mass Defacement by Turkish Hacktivists

At first it appeared that it was just the official site of Goa's DoIP, that's been defaced by Turkish defacers, but looking further the campaign gets much bigger than originally anticipated :

"The official website of the Goa government’s Department of Information and Publicity (DoIP) - goainformation.org - was hacked by a group of Turkish militants on Saturday. The hacker has not only defaced the website, replacing all information with the group’s propaganda material in Turkish language, but also posted some gory pictures of slain terrorists. The DoIP has now lodged a complaint with the Panjim Police and the Panjim crime branch is investigating the matter."

The campaign is aiming to send a PSYOPS signal to the rest of the world regarding the recent tensions between Turkey's military operations in northern Iraq against PKK, an action the U.S doesn't seem to enjoy at all. Some sample defaced sites are savymedia.com; itrit.com; sledderforever.com; pssoc.org; youthblood.org; prisonministry.com. The defacers are sending the following message :

"The United States of America who is feeding on and strengthening behind closed doors the universal terrorists, is the greatest terrorist country. pkk/kadek/hpg/kkk is the world's most bloody and brutal terrorism group. They killed approximately 35.000 innocent people without any cruel till now. All the nations and states must know which are supporting these bloody and brutal terrorism groups, supporting terrorism will brings suffer and deathness. We are always be a side of peace. but we have always some words to say these terrorists "which" wants to seperate us and kill innocent people"

Moreover, Turkish hacktivists from another group have also been active recently by defacing the Assyrian Academic Society, Assyrian actress and author Rosie Malek-Yonan's site, and International Campaign to Support the Christians of Iraq petition's site. Three other Turkish hacktivists are also currently defacing under the handles of NusreT, MUSTAFAGAZI, and Storm, using the same defacement templates. The first group is reachable at a closed forum turkmilliyetcileri.org, and the second at turkittifak.org. Apparently, these groups are all under the umbrella of the Turkish Republican Hackers group.
