Cybercriminals release Socks4/Socks5 based Alexa PageRank boosting application

Feb 4, 2014 | Industry Intel, Threat Lab

Since its inception in 1996, Alexa has positioned itself as primary Web metrics data portal, empowering Web masters, potential investors, and marketers with access to free analytics based on data gathered from toolbars installed on millions of PCs across the world. Successfully establishing itself as the most popular, publicly accessible Web site performance benchmarking tool, throughout the years, the Alexa PageRank has acted as a key indicator for the measurement of a Web site’s popularity, growth and overall performance, often used in presentations, competitive intelligence campaigns, and comparative reviews measuring the performance/popularity of particular Web sites.

Operating in a world dominated by millions of malware-infected hosts, converted to Socks4/Socks5 for, both, integration within automatic account registration tools, DoS tools, in between acting as anonymization ‘stepping-stones’, cybercriminals continue utilizing this legitimate, clean IPs-based infrastructure for purely malicious and fraudulent purposes. Their latest target? Utilizing the never-ending supply of malware-infected hosts to influence Alexa’s PageRank system. A newly released, commercially available, DIY tool is pitching itself as being capable of boosting a given domain/list of domains on Alexa’s PageRank, relying on the syndication of Socks4/Socks5 malware-infected/compromised hosts through a popular Russian service.

Cybercriminals release new Web based keylogging system, rely on penetration pricing to gain market share

Jan 31, 2014 | Industry Intel, Threat Lab

In need of a fresh example of penetration pricing, within the cybercrime ecosystem, used by a cybercrime-friendly vendor in an attempt to quickly gain as much market share as possible in the over-supplied market segment for keylogging-specific systems? We’re about to give you a very fresh one.

A newly released, commercially available PHP/MySQL based, keylogging-specific malware/botnet generating system, with full Unicode support, is currently being offered for $5o, with the binary re-build priced at $20, in a clear attempt by the vendor to initiate basic competitive pricing strategies to undermine the market relevance of competing propositions. Just like the Web based DDoS/passwords-stealing tool that we profiled yesterday, this most recently released keylogging system is once again acting as a very decent example of a “me too” type of underground market release, whose overall success in the short term would mostly rely on basic branding, and whose long term success relies on the systematic introduction of new features.

To get a better view of the tool’s core functions, let’s take a peek at its administration panel.

Newly released Web based DDoS/Passwords stealing-capable DIY botnet generating tool spotted in the wild

Jan 30, 2014 | Industry Intel, Threat Lab

Driven by the never ending supply of newly released DIY (do it yourself) underground market releases, in combination with the systematically rebooted life cycles of releases currently in circulation, cybercriminals continue actively developing new cybercrime-friendly malware generating/botnet building applications. Motivated by the desire to further continue the monetization of this ever-green market segment, a key driving force behind the consequential rise of E-shops offering access to compromised accounting data like those we’ve extensively profiled at Webroot’s Threat Blog in the past, these cybercriminals continue to ‘innovate’ and reboot the life cycles of known releases through the systematic and persistent introduction of new features.

We’ve recently spotted a newly released, commercially available Web-based DDoS/Passwords stealing-capable DIY type of botnet generating tool, whose general availability is prone to empower potential cybercriminals with DDoS attack capabilities, as well as an efficient platform for the mass harvesting of accounting data, both of which will be inevitably monetized through the usual, now standardized monetization channels. Let’s take a peek inside the tool’s command and control interface, and discuss its key differentiation features in the broader context of their applicability in the overall threat landscape.

Newly launched managed ‘compromised/hacked accounts E-shop hosting as service’ standardizes the monetization process

Jan 24, 2014 | Industry Intel, Threat Lab

Regular readers of Webroot’s Threat Blog are familiar with our “A Peek Inside a Boutique Cybercrime-Friendly E-shop” series, originally started in 2012, highlighting the trend emerging at the time of boutique based E-shops selling access to compromised/hacked accounts. Popping up on our radars on systematic basis, this maturing market segment is already entering in a new life cycle stage in early 2014. The current stage is the direct result of the ongoing efficiency-oriented mentality applied by cybercriminals over the years in the face of the active implementation of tactics such as, for instance, templatization, ultimately leading to standardization of key cybercrime ecosystem processes, resulting in improved return on investment/stolen assets liquidity for their fraudulent operations.

Fully automated, API-supporting service, undermines Facebook and Google’s ‘SMS/Mobile number activation’ account registration process

Jan 22, 2014 | Industry Intel, Threat Lab

Operating in a world dominated by millions of malware-infected hosts acting as proxies for the facilitation of fraudulent and malicious activity, the Web’s most popular properties are constantly looking for ways to add additional layers of authentication to the account registration process of prospective users, in an attempt to undermine automatic account registration tactics. With CAPTCHA under automatic fire from newly emerging CAPTCHA solving/breaking services, re-positioning the concept from what was once the primary automatic account registration prevention mechanism, to just being a part of the ‘authentication mix’ these days, in recent years, a new (layered) authentication concept got the attention of the Web’s ‘most popular’. Namely, the introduction of SMS/Mobile number account verification, a direct result of wide adoption of mandatory prepaid SIM card registration internationally, in the context of preventing crime and terrorism.

Naturally, the bad guys quickly adapted to the new authentication mechanism, and in a true ‘malicious economies of scale’ fashion, undermined the concept, successfully continuing to populate any Web property with hundreds of thousands of bogus accounts, degrading the quality of the services offered, as well as directly abusing the one-to-one/one-to-many trust model in place. How do they do it? What type of tactics do they rely on in an attempt to bypass the mandatory prepaid SIM cards registration process, in order to secure a steady flow of tens of thousands of non-attributable SIM cards, at any given moment in time, empowering them to bypass the SMS/Mobile number activation account registration process? Let’s find out.

Google’s reCAPTCHA under automatic fire from a newly launched reCAPTCHA-solving/breaking service

Jan 21, 2014 | Industry Intel, Threat Lab

It can be easily argued, that CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart), is the modern day’s ‘guardian of the Web’, in the context of preventing the mass, systematic, and efficient abuse of virtually each and every Web property there is.

Over the years, CAPTCHA developers continued to strike a balance between the actual usability and sophistication/resilience to attacks, while excluding the beneath the radar emergence of a trend, which would later on prove to successfully exploit a fundamental flaw in the very concept of the CAPTCHA process. Namely, the fact that, the very same humans it was meant to differentiate against the automated bots, would start to efficiently monetize the solving process, relying on the ‘human factor’, instead of applying scientific based type of attack methods.

Acquired by Google in 2009, reCAPTCHA, quickly emerged as a market leader in the space, leading to good old fashioned (eventual) exploitation of monocultural type of flaws, applied not just by security researchers, but naturally, by cybercriminals as well. How do cybercriminals bypass the Web’s most popular CAPTCHA? Do they rely on human-factor type of attacks, or continue aiming to scientifically break it, like it is most commonly assumed by CAPTCHA developers? Based on the average response times that we’re aware of, a newly launched CAPTCHA-solving/breaking service, that’s exclusively targeting Google reCAPTCHA, might have actually found a way to automate the process, as we’re firm believers in the fact that, no ‘CAPTCHA solving junkie’, can solve a reCAPTCHA in less than a second. Let’s take a peek inside the service, discuss its relevance in the CAPTCHA-solving/breaking market segment, and why its reliance on an affiliate network type of revenue sharing scheme, is poised to help the service, further acquire high-end customers, namely vendors of blackhat SEO/spam tools.

DIY Python-based mass insecure WordPress scanning/exploting tool with hundreds of pre-defined exploits spotted in the wild

Jan 17, 2014 | Industry Intel, Threat Lab

Throughout 2013, we not only witnessed the re-emergence of proven mass, efficiency-oriented Web site hacking/exploitation tactics, such as, the reliance on Google Dorks scanning, good old fashioned brute-forcing, but also, the introduction of new concepts, successfully utilizing/standardizing, both, compromised accounting data, and server-farm level access, in an attempt to fraudulently monetize the hijacked traffic from legitimate Web sites.

As we’ve seen on numerous occasions throughout the years, despite sophisticated ‘innovations’, cybercriminals are no strangers to the KISS (Keep It Simple Stupid) principle. Case in point in terms of Content Management Systems (CMSs) is WordPress, whose market share is naturally proportional with attention the platform is receiving from fraudulent/malicious adversaries. In this post, I’ll discuss a DIY type of Python-based mass WordPress scanning/exploiting tool, available on the underground marketplace since July 2013, emphasize on its core features, and overall relevance in a marketplace dominated by competing propositions.

New TDoS market segment entrant introduces 96 SIM cards compatible custom GSM module, positions itself as market disruptor

Jan 16, 2014 | Industry Intel, Threat Lab

In need of a good example, that malicious adversaries are constantly striving to ‘innovate’, thereby disrupting underground market segments, rebooting TTPs’ (tactics, techniques and procedures) life cycles, standardizing and industrializing their fraudulent/malicious ‘know-how’? We’re about to give you a pretty good one.

Regular readers of Webroot’s Threat Blog, are no strangers to the emerging TDoS (Telephony Denial of Service) underground market segment. Primarily relying on the active abuse of legitimate services, such as, for instance, Skype and ICQ, as well as to the efficient and mass abuse of non-attributable SIM cards, for the purpose of undermining the availability of a victim’s/organization’s mobile/communication’s infrastructure, the market segment continues flourishing. Rather a trend, than a fad, established DDoS (Distributed Denial of Service) for hire vendors, are already busy ‘vertically integrating’ within the underground marketplace, by starting to offer TDoS for hire services, either relying on a partnership with a TDoS vendor, or through the reliance on an in-house built infrastructure, established through the use of public/commercially available TDoS tools.

Back in July, 2012, a relatively unknown underground market entrant, publicly announced his ambitions to build a custom TDoS-ready GSM module, capable of supporting between 100-200 non-attributable SIM cards simultaneously, using custom coded management software. In a true product customer-ization style, he also started soliciting feedback, and touching base with potential customers of the custom module, in between promising them a “democratic” pricing scheme for the upcoming release. Then came the ‘innovation’. In November 2013, he made commercially available, what we believe is the first such public/commercially available TDoS-ready custom GSM module, whose very existence is poised to further fuel the growth of the TDoS market segment, tip potential competitors to the rise of the market segment, and directly contribute to the emergence of new TDoS vendors.

Let’s discuss the custom GSM module’s core functionalities, pricing scheme, and why its vendor can easily claim the market disruptor position in early 2014.

SMS Trojans Using Adult Content On The Rise In Android

Jan 15, 2014 | Industry Intel, Threat Lab

In the marketing world, it’s widely known sex sells. This is so true the “adult” industry is a multi-billion dollar industry. This is also why malware authors have long used adult content to attract unwitting victims. Lately, this threat researcher has seen way too much of it. There has been an influx of Trojan-like APKs using adult content to trick users into sending premium SMS messages. Let’s take a deeper look at one of these apps.

When you open the app it displays a page showing “GET IT NOW” in the middle, and “NEXT” at the lower right corner. If you tap “GET IT NOW”, it pops up a message saying “Request sent. Thank You”, and goes to the next screen. If you press “NEXT”, it goes to the next screen without a message. After several screens like this, it eventually gets to the last screen which may or may not have several buttons, but always has “T&C”, which I can only guess means “Terms & Conditions”. This opens up an SMS agreement screen.

Using Google translate, the SMS agreement – which is in Indonesian – roughly translates to this:

Subscribe to a few videos now! Click on the mobile, you will be a customer subscription and retrievable content, cost RM3.00/SMS caj, 1-2 day per SMS (not including GPRS caj so canceled). To deselect, sms STOP conductivity to 39 997. Talian CS: 03-7493 1352 (Isnin to Friday). By concatenated, you agree with the terms and conditions that presented.

Click “OK” and you’ll be charged via premium SMS. So what about the “content” that’s promised? Sorry, not going to happen.

Not all, but quite a few of these apps are using the same package name pattern:

com.<naughty_word>.kma2
com.<naughty_word>.gmb2
com.<naughty_word>.lmt2
com.<naughty_word>.ymb2
com.<naughty_word>.mbf2

When looking for “content” out there, be smart about it. If an app is asking you to agree to subscribe to something via premium SMS messages, think twice. Of course, it always helps to have a malware scanner on your phone, like Webroot SecureAnywhere Mobile, as well.

Vendor of TDoS products resets market life cycle of well known 3G USB modem/GSM/SIM card-based TDoS tool

Jan 13, 2014 | Industry Intel, Threat Lab

Driven by popular demand, the underground market segment for TDoS (Telephony Denial of Service) attacks continues flourishing with established vendors continuing to actively develop and release new DIY (do-it-yourself) type of tools. Next to successfully empowering potential customers with the necessary ‘know-how’ needed to execute such type of attacks, vendors are also directly contributing to the development of the market segment with new market entrants setting up the foundations for their business models, using these very same tools, largely relying on the lack of situational awareness/understanding of the underground market transparency of prospective customers. Positioned in a situation as ‘price takers’, they’d be often willing to pay a premium to gain access to TDoS type of attack capabilities, with the intermediary in a perfect position to command a high profit margin, further improving the market segment’s capitalization.

A well known (Russian) vendor of TDoS products continues ‘innovating’ and utilizing basic customer-ization concepts, thereby introducing new features into well known TDoS ‘releases’, bug fixes, and overly-continuing to actively maintain a decent portfolio of multiple TDoS applications. Let’s take a peek at the most recently updated, 3G USB Modem/GSM/SIM card based of TDoS attack application, dubbed by the vendor as the most effective and cost-effective form of TDoS attack.

New “Windows 8 Home Screen’ themed passwords/game keys stealer spotted in the wild

Jan 9, 2014 | Industry Intel, Threat Lab

First official working week of 2014 and cybercriminals are already busy pushing new releases into the underground marketplace. The goal? Setting up the foundation for successful monetization schemes to be offered through cybercrime-friendly boutique E-shops known for selling access to compromised accounting data obtained through the use of DIY (do-it-yourself) type of services. In this post, I’ll discuss a newly released passwords/game keys stealing tool whose Web-based command and control interface is successfully mimicking Windows 8’s Home Screen, and some of the most common ways through which this very same stolen accounting data would eventually be monetized.
