In a self-contradicting social engineering attempt, a malware author is offering to sale a (updated version of Kardphisher) DIY fake Windows XP activation builder, which despite the fact that it claims "We will ask for your billing details, but your credit card will NOT be charged", is requesting and remotely uploading all the credit card details required for a successfully credit card theft.

Perhaps among the main reasons why such simplistic social engineering attempts never scaled in a "malicious economies of scale" approach, is because sophisticated crimeware kits capable of obtaining the very same data automatically, started leaking for everyone to start taking advantage of - including yesterday's cybercriminals using such DIY fake message builders.

Moreover, according to recently reseased survey results, end users cannot distinguish between fake popups and real ones, and on their way to continue doing what they were doing, click OK on that pesky warning message telling them that they're about to get infected with malware. Taking into consideration the fact that the popup windows the researchers used look like cheap creative compared to the average fake security software's layout high quality GUIs, it is perhaps worth restating your research questions with something in the lines of - What motivates end users to install an antivirus application going under the name of Super Antivirus 2009 or Mega Virus Cleaner 2008? The fact that the fake status bar is telling them that they're infected with 47 spyware cookies, or the fact that they ended up at the fake site while browsing their trusted web services?

The increase of rogue security software domains is happening due to the high payout affiliation based model, the standardized creative allowing the participants to come up with their own fake names if they want to, and due to the fact that the fake security threats scareware approach seems to be perfectly taking advantage of the overall suspicion on the effectiveness of their legitimate security software.

We're slowly entering into a stage where RBN bullet proof hosting franchises are vertically integrating, and due to the requests from their customers are starting to offer that they refer to as "mirrored hosting" which in practice is plain simple fast flux network consisting of RBN-alike purchased netblocks, and naturally, botnet infected hosts.

Managed fast-fluxing is only starting to go mainstream, for instance, in July I found evidence that money mule recruiters were using ASProx's infected hosts as hosting infrastructure, and in November, 2007, an infamous spamming software vendor was also found to have been offering fast-flux services in the past.

In this most recent fast-flux service, we have a known spammer and botnet master that in between self-serving himself on is way to ensure his portfolio of scammy domains remains online for a "little longer", is commercializing fast-fluxing and is offered a DIY service :

"Finally after hardwork and great appreciation from our normal bullet proof hosting/server clients we are able to launch Mirrored hosting. What is Mirrored hosting ?

================
Mirrored hosting is a powerful mirrored web hosting management, uses multiple Virtual servers to host website with 100% uptime. Mirrored hosting is a combination of two things, which are:

1. Specially Designed Virtual Servers
2. Powerful Automated Control Panel

How does it work ?
=============== 

Mirrored hosting uses specially configured Virtual Servers making them link with the Mirrored hosting Control Panel which is then controlled by our own control panel allowing us to provide smooth streamline hosting with no downtime. No one is able to trace original IP of the server or the place where the files are hosted so the websites/domains hosted have a 100% Uptime. This is achieved by unique customisation of our Virtual Servers.

Actually, it takes ips around the world and our powerful control panel just rotates the ips every 15 minutes. though all these ips you will see will be fake no one can trace the orignal ip where files are hosted. Sometimes the ip is from China, Korea, USA, UK, Japan, Lithuania etc."

The concept has always been there for cybercriminals to take advantage of, but once it matures into a managed service it would undoubtedly lower down the entry barriers allowing yesterday's average phishers to take advantage of what only the "pros" were used to.

Such disclaimers make you wonder what's the point of including a notice forwarding the responsibility for the upcoming cybercrime activities to the buyer, when the seller himself is offering daily updates with undetected bots, and is promising to include new exploits within the kit.

For the time being, this recently released copycat web exploitation malware kit, includes two PDF exploits, IE snapshot, and naturally MDAC, with a DIY builder for the binary. Here's the disclaimer, greatly reminding us of Zeus's copyright notice :

"Purchasing this product, you hold the full responsibility for its usage and for consequences which may have been caused by incorrect usage or the usage with some evil intent or violation of the usage rules. The author excludes the placement of the scripts somewhere on the Internet, you can only place them on localhost, virtual machine or on a test botnet (minibotnet). WARNING! The usage of this product with evil intent leads to the criminal responsibility!"

What happens when the buyer tries to resell the kit? - "If you try to resell, decode, remove the boundaries, you will lose all the support, updates and guarantees." which is surreal considering that the kit is open source one, and just like we've seen with a recent modification of Zeus if it were to include unique features -- which it doesn't -- others would build upon its foundations.


Going through the exploitation statistics of a sample campaign, you can clearly see that out of the 859 unique visits 250 got exploited with outdated and already patched vulnerabilities. Therefore, diversifying the exploits set would have increased the number of exploited hosts.

With IE6 visitors exploited at 46% as a whole, it would be hard not to notice that just like Stormy Wormy's historical persistence of using outdated vulnerabilities, a great majority of today's botnets have been aggregated using old exploits.

Trying to enforce the intellectual property of a malware kit means you're claiming ownership, and therefore the disclaimer becomes irrelevant.

Modified versions of popular open source crimeware kits rarely make the headlines due to the fact that anyone can hijack a crimeware kit's brand, build and innovate using its foundations, and claim it's a new version released by the original authors. That's of course in between the tiny time frame until he's exposed as the fake author of Zeus that may have in fact came up with a unique feature that the original authors didn't include.

This modified version of Zeus is yet another example of how cybercriminals are actively modifying crimeware kits, literally making such practices as keeping version numbers irrelevant. While the administrator is managing his botnet, he can load local, or tunein the built-in online radio stations the author of this modification included, next to changing Zeus entire graphical layout.

Let's take into consideration another example, the infamous Pinch DIY malware builder, that's been around for over 4 years. With the populist arrest of its authors in 2007, cybercriminals are still innovating on the foundations offered by Pinch, and thanks to its publicly obtainable source code. It's also worth pointing out that these two Zeus and Pinch modifications are courtesy of a single individual, that in between modifications of popular crimeware kits, seems to be busy porting different modules on different malware kits and web based malware, knowingly or unknowingly contributing to the convergence of spamming, DDoS, web based malware, and botnet management kits.

From a sarcastic perspective - what's next? Perhaps a built-in slideshow of random screenshots taken from malware infected desktops in the botnet, or even a pink layout modification for female botnet masters. Customerization, and customer tailored services can make anything happen, and naturally enjoy the higher profit margins.

Commoditization or commercialization, Themida or Code Virtualizer, individually crypting or outsourcing to an experienced malware crypting service offering discounts on a volume basis next to detection rates of the crypted binary offered by a trusted online scanner that is NOT distributing the samples to the vendors? These are just some of the questions malware authors often ask themselves, while others distribute pirated copies of Code Virtualizer urging everyone to start taking advantage of commercial anti-reverse engineering tools to make their malware harder to analyze. Once again, just like we've seen before, a legitimate commercial application can come handy in the hands of the wrong people :

"Code Virtualizer will convert your original code (Intel x86 instructions) into Virtual Opcodes that will only be understood by an internal Virtual Machine. Those Virtual Opcodes and the Virtual Machine itself are unique for every protected application, avoiding a general attack over Code Virtualizer. Code Virtualizer can protect your sensitive code areas in any x32 and x64 native PE files (like executable files/EXEs, system services, DLLs , OCXs , ActiveX controls, screen savers and device drivers).

Code Virtualizer can generate multiple types of virtual machines with a different instruction set for each one. This means that a specific block of Intel x86 instructions can be converted into different instruction set for each machine, preventing an attacker from recognizing any generated virtual opcode after the transformation from x86 instructions. The following picture represents how a block of Intel x86 instructions is converted into different kinds of virtual opcodes, which could be emulated by different virtual machines.

When an attacker tries to decompile a block of code that was protected by Code Virtualizer, he will not find the original x86 instructions. Instead, he will find a completely new instruction set which is not recognized by him or any other special decompiler. This will force the attacker to go through the extremely hard work of identifying how each opcode is executed and how the specific virtual machine works for each protected application. Code Virtualizer totally obfuscates the execution of the virtual opcodes and the study of each unique virtual machine in order to prevent someone from studying how the virtual opcodes are executed."

With Cyber-as-a-Service business model becoming increasingly common, the entire quality assurance model in respect to malware is slowly maturing from individual malware crypting propositions, where the seller of the service is basically taking advantage of a diverse set of public/private tools, into DIY web services offering crypting discounts on a volume basis, and perhaps most importantly - improving the customer's experience by letting him take advantage of the inventory of crypting tools and bypassing verification services. Within the tool's inventory are naturally lots of (pirated) commercial anti-reverse engineering tools.

As we've seen before, whenever someone starts commercializing what used to be a self-selving process, others will either follow, or disintermediate their services by persistently releasing crypting tools for free in the wild. At the end of the day, it's all a matter of how serious they're about commercializing this market segment, and taking into consideration that a spamming vendor is offering malware crypting services "in between" the rest of the services in their portfolio, this underground cash cow is yet to prove itself in the long term.

We're slowly entering into "can you find the ten similarities" stage in respect to web malware exploitation kits, and their coders continuous supply of copycat malware kits under different names, taking advantage of different exploits combination. Copycat web malware exploitation kits are faddish, however, from a strategic perspective, releasing exploits kits like this one covered by Trustedsource, consisting entirely of PDF exploits, can greatly increase the exploitability level of Adobe vulnerabilities in general.

A similar web malware exploitation kit, once again using only Adobe related exploits is Zopa. Have you seen this layout before? That's the very same layout MPack and IcePack were using, were in the sense of cybercriminals preferring to use much mode modular alternatives these days. Ironically, Zopa is more expensive than MPack and IcePack, with the coder trying to cash-in on its biased exclusiveness and introduction stage buzz generated around it.

The second web malware exploitation kit is relying on a mix of exploits targeting patched vulnerabilities affecting IE, Firefox and Opera, with its authors asking for $50 for monthly updates, updates of what yet remains unknown. Both of these kits once again demonstrate the current  mentality of the kit's coders having to do with -- thankfully -- zero innovation, fast cash and no long-term value.

However, modularity, convergence with traffic management kits, vertical integration with cybercrime services and bullet proof hosting providers, advanced metrics, evasive practices, improved OPSEC (operational security), and dedicated cybercrime campaign optimizing staff, are all in the works.

The less technologically sophisticated lone cybercriminals have always enjoyed the benefits of stand alone DIY applications. From DIY exploit embedding tools in a Cybercrime 1.0 world, maturing to today's web malware exploitation kits and their copycat alternatives, to plain simple spamming tools that matured into today's managed spamming services already starting to offer spamming services beyond email, stand alone spamming applications remain pretty popular.

With yet another Skype spamming tool released in the wild, which just like the previous one I discussed a couple of months relies on Skype's support for wildcast searches, and is spamming with authorization request messages until the user adds the contact, malicious parties seems to be more interested into supplying the desired services, than emphasizing on the quality assurance process.

Despite the possibilities for localized targeted attacks delivering messages with malicious URLs into the user's native language, benchmarking this tool's features next to the ones offered by certain bots taking advantage of social engineering by spamming the infected host's contacts, is positioning it far behind even the most primitive IM spreading bot modules, whose extra layer of social engineering personalization makes their IM malware campaigns much more effective ones.

Following the previous summaries of June's and July's threatscape based on all the research published during the month, it's time to summarize August's threatscape.

August's threatscape was dominated by a huge increase of rogue security software domains made possible due to the easily obtainable templates for the sites, several malware campaigns targeting popular social networking sites, Russian's organized cyberattack against Georgia with evidence on who's behind it pointing to "everyone" and a few botnets dedicated to the attack making the whole process easy to outsource and turn responsibility into an "open topic", several new web based botnet management kits and tools found in the wild, evidence that the 76service may in fact be going mainstream since the concept of cybercrime as a service is already emerging, and, of course, a peek at India's CAPTCHA solving economy, where the best comment I've received so far is that every site should embrace reCAPTCHA, so that while solving CAPTCHAs and participating in the abuse of these services in question, they would be also digitizing books. As usual, August was a pretty dynamic month for the middle of summer, with everyone excelling in their own malicious field.

01. McAfee's Site Advisor Blocking n.runs AG - "for starters"
False positives are rather common, especially when you're aiming to protect the end user from himself and not let him gain access to "hacking tools", but you're flagging security tools as badware and missing over half the SQL injected domains currently in the wild due to the fact that SiteAdvisor's community still haven't reviewed them - that's not good

02. The Twitter Malware Campaign Wants to Bank With You
Twitter, just like every Web 2.0 application, isn't and shouldn't be treated as a unique platform for dissemination of malware, since it's dissemination of malware "as usual". This particular malware campaign was not just executed by a lone gunman, but also, was taking advantage of a flaw allowing the author to add new followers potentially exposing them to the malicious links serving banker malware. For the the time being, MySpace, Facebook and Twitter accounts are the very last thing a malicious attacker is interesting in puchasing accounting data for, but how come? It's all due to the oversupply of automatically registered accounts at other popular services, whose ecosystem of Internet properties empower cybercriminals with the ability to launch, host and distribute malware in between abusing the very same company's services for the blackhat SEO campaign and redirection services. Theoretically, a distributed network build upon the services provided by a single company is faily easy to accomplish due to the single login authentication applied everywhere. A singly bogus Gmail account results in a blackhat SEO hosting blogspot account, flash based redirector hosted at Picasa, and a couple of thousands of spam emails sent automatically sent through Gmail in order to abuse it's trusted email reputation
 
03. Compromised Web Servers Serving Fake Flash Players
If aggressiveness matter, this campaign consisting of remotely injected redirection scripts at legitimate sites next to on purposely introduced malware oriented domains, was perhaps the most aggressive one during the month. Fake flash players, fake windows media players and fake youtube players are prone to increase as a social engineering tactic of choice due to the template-ization of malware serving sites for the sake of efficiency

04. Pinch Vulnerable to Remotely Exploitable Flaw
With Zeus vulnerable to a remotely exploitable flaw allowing cybercriminals to hijack other cybercriminal's Zeus botnet, private exploits targeting the still rather popular at least in respect to usefulness Pinch malware are leaking, allowing everyone including security researchers to take a peek at a particular campaign running unpatched Pinch gateway

05. Phishers Backdooring Phishing Pages to Scam One Another
Backdooring phishing pages is perhaps the most minimalistic approach a cybercriminal wanting to scam another cybercriminal is going to take. The far more beneficial approach that I've encountered on a couple of occassions so far, would be to backdoor a proprietary web malware exploitation kit, release it in the wild, let them put the time and efforts into launching the campaigns, then hijack their botnet. In fact, the possibilities for backdooring copycat web malware exploitation kits in order to take advantage of the momentum while introducing a non-existent kit has always been there at the disposal of malicious attackers. One thing's for sure - there's no such thing as a free web malware exploitation kit, just like there isn't such thing as a free phishing page

06. Email Hacking Going Commercial - Part Two
In between the scammers promising the Moon and asking for anything between $20 to $250 to hack into an email account, there are "legitimate" services taking advantage of web email hacking kits consisting of each and every known XSS vulnerability for a particular service in an attempt to increase the chances of the attacker. And given that the majority of these have been patched a long time ago, social engineering comes into play. Do these services have a future? Definitely as more and more people are in fact looking for and requesting such services, in fact, they're willing to pay a bonus considering how exotic it is for them to have any email that they provide hacked into and the accounting data sent back to them

07. The Russia vs Georgia Cyber Attack
Event of the month? Could be, but just like every "event of the moth" everyone seems to be once again restating their "selective retention" preferences. What is selective retention anyway? Selective retention is basically a situation where once Russian is attacking another country's infrastructure, you would automatically conclude that it's Russian FSB behind the attacks and consciously and subconsciously ignore all the research and articles telling you otherwise, namely that the FSB wouldn't even bother acknowledging Georgia's online presence, at least not directly. Moreover, talking about the FSB as the agency behind the cyberattacks indicates "selective retention", talking about FAPSI indicates better understanding of the subject.

In times when cybercrime is getting ever easier to outsource, anyone following the news could basically orchestrate a large scale DDoS attack against a particular country in order to forward the responsibility to any country that they want to. In Russia vs Georgia, you have a combination of a collectivist society that's possessing the capabilities to launch DDoS attacks, knows where and how to order them, and that in times when your country is engaged in a war conflict drinking beer instead of DDoS-sing the major government sites of the adversary is not an option.

Selective retention when combined with a typical mainstream media's mentality to "slice the threat on pieces" instead of turning the page as soon as possible, is perhaps the worst possible combination. Furthermore, coming up with Social Network analysis of the cyberattacks would produce nothing more but a few fancy graphs of over enthusiastic Russian netizen's distributing the static list of the targets. The real conversations, as always, are happening in the "Dark Web" limiting the possibilities for open source intelligence using a data mining software. Things changed, OPSEC is slowly emerging as a concept among malicious parties, whenever some of the "calls for action" in the DDoS attacks were posted at mainstream forums, they were immediately removed so that they don't show up in such academic initiatives

08. 76Service - Cybercrime as a Service Going Mainstream
The reappearance of the 76Service allowing everyone to log into a web based interface and collect all the accounting and financial data coming from malware infected hosts across the globe for the period of time for which they've bought access, indicates that what used to be proprietary services which were supposedly no longer available, are now being operated in a do-it-yourself fashion. Goods and products mature into services, so from a cost-benefit analysis perspective, outsourcing is naturally most beneficial even when it comes to cybercrime

09. Who's Behind the Georgia Cyber Attacks?
If it's the botnets used in the attacks, they are known, if it's about who's providing the hosting for the command and control, it's the "usual suspects", but just like previous discussion of the Russian Business Network, it remains questionable on whether or not they work on a revenue-sharing basis, are simply providing the anti-abuse hosting, or are the shady conspirators that every newly born RBN expert is positioning them to be.

Cheap conversation regarding the RBN ultimately serves the RBN, and just for the record, there's a RBN alternative in every country, but the only thing that remains the same are the customers, tracking the customers means exposing the RBN and the international franchises of their services, making it harder to identify their international operations. And given that the "tip of the iceberg", namely RBN's U.S operations remain in tact, talking about taking actions against their international operations in countries where cybercrime law is still pending, is yet another quality research into the topic building up the pile of research into the very same segments of the very same ISPs.

Just for the record - these "very same ISPs" are regular readers of my blog, and if you analyze their activities, they're definitely reading yours too, ironically, surfing through gateways residing within their netblock that are so heavily blacklisted due to the guestbook and forum spamming activities that their bad reputation usually ends up in another massive blackhat SEO campaign exposed.

10. Guerilla Marketing for a Conspiracy Site
Conspiracy theorists may in fact have a new wallpaper to show off with

11. Banker Malware Targeting Brazilian Banks in the Wild
When misinformed and not knowing anything about a particular underground segment, a potential cybercriminal would stick to using such primitive compared to the sophisticated banker malware kits currently in the wild. These sophisticated banker malware kits are often coming in a customer-tailored proposition, with their price increasing or decreasing based on the specific module to be included or excluded. For instance, a module targeting all the U.S banks that has been put in a "learning mode" long before it was made available to the customers can be requested and is often available with the business model build around the customer's wants 

12. Compromised Cpanel Accounts For Sale
Despite the massive SQL injection attacks, accounting data for Cpanel accounts coming from malware infected hosts seems to be once again coming into play, which isn't surprising given the filtering capabilities and log parsing tools today's botnet masters are empowered with. These very same compromised Cpanel accounts and the associated domains often end up so heavility abused that it's tactics like these that are driving the underground multitasking mentality, namely, abusing a single compromised account for each and every malicious online activity you can think of - even hosting banners for their blackhat SEO services

13. A Diverse Portfolio of Fake Security Software - Part Two
In August we saw a peek of fake security software, neatly typosquatted domains whose authors earn revenue each and every time someone installs the software. The vendors behind this software are forwarding the entire process of driving traffic to those excelling in aggregating traffic and abusing it. As anticipated, underground multitasking started taking place within the fake security software domains, with the people behind them introducing client-side exploits in order to improve the monetization of the traffic coming to the sites

14. DIY Botnet Kit Promising Eternal Updates
There's no such thing as a (quality) free botnet kit. What's for free is often the leftovers from a single feature of a more sophisticated proprietary botnet kit. This one in particular is however trying to demonstrate that even a plain simple GUI botnet command and control software can achieve the results desired by an average script kiddie, and not necessarily satisfy the needs of the experienced botnet master

15. A Diverse Portfolio of Fake Security Software - Part Three
As far as trends and fads are concerned, the majority of the domains are currently parked at up to four different IPs, with most of them going into a stand by mode once they get detected and reappear back couple of weeks later

16. Fake Celebrity Video Sites Serving Malware - Part Two
Due to the template-ization of fake celebrity video sites, and simple traffic management tools combined with blackhat SEO tactics, these sites are also prone to increase in the next couple of months

17. Web Based Botnet Command and Control Kit 2.0
It's releases like these that remind us of the amount of time, efforts and personal touch that a malicious attacker would put into such a management kit, currently acting as a personal benchmark as far as complexity and features indicating the coder's experience with botnets is concerned. What's he's failing to anticipate is that this kit is sooner or later going to turn into the "MPack of botnet management"

18. A Diverse Portfolio of Fake Security Software - Part Four
Keep it coming, we'll keep it exposing until we end up getting down to the "fake software vendor" itself

19. Automatic Email Harvesting 2.0
Email harvesting is slowly maturing into a vertically integrated service provided by vendors of managed spamming services. This email harvesting module is aiming to close the page on text obfuscation in respect to fighting spam, and is successfully recognizing and collecting such publicly available emails. From a psychological perspective though, the end users who bothered to obfuscate their emails are less likely to fall victims into phishing scams, with the obfuscation speaking for a relatively decent situational awareness on how they emails end up in a spammer's campaign

20. Fake Porn Sites Serving Malware - Part Three
As a firm believer in sampling in order to draw conclusions on the big picture, an approach that has proven highly accurate in modeling historical and upcoming tactics and behavior, a single fake porn site serving malware campaign usually exposes a dozen of misconfigured redirectors, which thanks to their misconfiguration despite the evasive features available within the kits, expose another dozen of malware campaigns

21. Facebook Malware Campaigns Rotating Tactics
With no particular flaw exploited other than the social engineering tactic of using already compromised Facebook accounts who would automatically spam all their friends with links to flash files hosted at legitimate services, the more persistent the campaign is, the higher the chance that it will scale enough. This campaign in particular is mainly relying on rotation of tactics, namely different messages, different services and file extensions used in order to trick someone's friend into visiting the URL. With the number of users increasing, the most popular social networking sites are naturally going to be permanently under attacks from cybercriminals

22. Fake Security Software Domains Serving Exploits
Despite that it's a single brand, namely the International Virus Research Lab that's introducing client-side exploits within it's portfolio of domains, the opportunity for abuse may be noticed by the rest of the brands pretty fast

23. Exposing India’s CAPTCHA Solving Economy
Taking into consideration the mentality surrounding a particular country's cybercriminals, how they think, how they operate, what do they define as an opportunity, and how much personal efforts are they willing to put into their campaigns, I wouldn't be surpised if a Russian vendor offering 100,000 bogus Gmail accounts for sale has in fact outsourcing the account registration process to Indian workers, paid them pocket change and is then reselling them ten to twenty times higher than the price he originally paid for them.

The text based CAPTCHAs used at the major Internet portals and services, are so efficiently abused by this approach that continuing to use is directly undermining the trust these email providers and services often come with as granted

Is it a Remote Administration Tool (RAT) or is it malware? That's the rhetorical question, since RATs are not supposed to have built-in Virustotal submission for the newly generated server, antivirus software "killing" and firewall bypassing capabilities.

Taking a peek into some of commodity features aiming to make it harder to analyze the malware found in pretty much all the average DIY malware builders available at the disposal at the average script kiddies, one of the latest releases pitched as RAT while it's malware clearly indicates the commoditization and availability of such modules :

" - FWB (DLL Injection, The DLL is Never Written to Disk)
 - Decent Strong Traffic Encryption

Malware coders or "malware modulators"? With the currently emerging malware as a web service toolkits porting common malware tools to the web, drag and drop web interfaces for malware building are definitely in the works.

For the cheap cybercriminals not wanting to invest a couple of thousand dollars into purchasing a cutting edge web malware exploitation kit -- a pirated copy of which they would ironically obtained several moths later -- with all the related and royalty free updates coming with it, there are always the copycat malware kits like this one offered for $100.

Taking into consideration the proprietary nature of some of the kits, the business model of malware kits was mostly relying on their exclusive nature next to the number, and diversity of the exploits included in order to improve the infection rate. This simplistic assumption on behalf of the coders totally ignored the possibility of their kits leaking to the general public, or copies of the kits ending up as a bargain in particular underground deal where the once highly exclusive kit was offered as a bonus.

"Me too" web malware kits were a faddish way to enjoy the popularity of web malware kits like MPack and Icepack and try to cash in on that popularity by coming up average kits lacking any significant differentiation factors in the process. But just like the original and proprietary kits, whose authors didn't envision the long term growth strategy of integrating different services into their propositions or the kits themselves, the authors of copycat malware kits didn't bother considering the lack of long-term growth strategy for their releases. Branding in respect to releasing a Firepack malware kit to compete with Icepack which was originally released to compete with Mpack, has failed to achieve the desired results as well.

And with malware kits now a commodity, and underground vendors excelling in a particular practice with the long term objective to vertically integrate in their area of expertise -- think spammers offering localization of messages into different languages and segmented email databases from a specific country -- would we witness the emergence of managed cybercrime services charging a premium for providing fresh dumps of credit card numbers, PayPal, Ebay accounts or whatever the buyer is requesting?

That may well be the case in the long term.
