The Global Security Challenge - 2007

The Global Security Challenge have just announced the world's five most promising security startups chosen to compete at the GSC Final in London for a $500K grant this November. They are:

- Auxetix (UK) - fortifies protection against multiple explosions through helical-auxetic nets

- EyeMarker (USA) - scans the eye to rapidly and non-invasively assess a person's health

- NoblePeak Vision (USA) - enabling the rapid detection and identification of people and objects at night without active illumination

- Psylock (Germany) - identifies users through biometric analysis of typing behavior

- XID Technology (Singapore) - face synthesis technology for real-time 3D rediction/replacement in a 2D video

Disintermediating the main sources of R&D with innovation and cost-effectiveness in mind, is a business practice that's already embraced by numerous deep pocketed future clients interested in outsourcing innovation in the form of such contests. I'm particularly interested in Psylock's future development, and it's great to note that the folks behind this typing behavior authentication even set up a demo of the concept.

And given that the GSC are also embracing the blogosphere, let's wish them long-term passion and sustained professionalism in their initiative to fund promising security oriented startups. Continue reading →

Managed Spamming Appliances - The Future of Spam

What's the future of spam? Spammers breaking CAPTCHAs of legitimate email providers and take advantage of their clean IP reputation to send out their junk, or spammers cooperating with botnet masters supplying newly infected hosts? Try outsourcing as a concept by renting a "managed spamming appliance" like the ones advertised as of recently.

This is an automatically translated excerpt from a recent proposition for a newly developed spam system that comes in the form of hardware with embedded botnet, just consider the idea for a second before reading and you'll get the point :

Among spammers very agreement that spam has become a profitable and die their last months, years. And it is understandable: profit fell, suppliers downloads expensive prices almost to the size of profits, a dozen well-known and had a good year or two ago turnover spammers departed from the market, so even monsters flow of spam once died theme ran in the stream than definitive did the topic boring.

I am pleased to present to you the technology that will make your distribution more efficient and voskresit characteristic of the spam profits.

Our software allows you spamit in such quantities that letter competitors simply lost among your. Also you get tools to control the delivery of letters and inboks spam those domains that are not being held by any other spam.

We have reached the maximum speed possible with the distribution of each bot and defended it against possible anti-virus and firewalls. In doing so, your botnety invincible. Interesting? And now in more detail.

Overall software works like any other botmeyler. Botnet controlled part of a server, it created letters and mailing bases loaded. Botha knocking over the job to a server, get a piece base, and a letter vdohnovlenno spamyat until the turn will come next door for the job.

Each server keeps 2500 + online bots, and the maximum speed reaches 7000 mailing letters per second, is the highest speed of all current market spam systems. Of course, the speed depends largely on the quantity and quality of downloads, quality and type of database (country, large domains, etc). 2500 online for you too little? No problem. Berit 2, 5, 10 servers, as long as you want.

In our system, there is every possible means to randomise from any randomise texts finishing randomnyh generate images on the fly or finished morphing images, as well as the ability to create their own makro-skripty. You can independently create and edit headers (if there is time to do so, fresh headlines you will download our spam-inzhenery).

You can do so zarandomlennye letter, as far themselves want. After randomization letter, you can immediately check finished look and see the results of the verification Spam Assasin ohm.

For specific newsletters (probiv major domains, etc), there is a possibility in detail settings bots (different types of reactions to the texts of error codes and mail servers). You can customize the system to thin to work with certain domains to improve the quality and speed of spam to these domains, identifying the individual parameters for each domain (how many letters it takes for a session timeouts, own blacklist bots, enter special codes for SMTP session for given domain, etc.)

To avoid zamorachivatsya processing bases on a separate server, all options included in the processing software. Among them: removal from the database of addresses abuzerov, splitting bases on the large and normal domains merger bases subtraction bases and checking for uniqueness.

24 hours a day, 7 days a week, you can use the services tehpodderzhki and complex issues of sending spam to discuss with our engineers. In addition, you can order the service "personal manager" who will help draw up a letter to monitor the continuous distribution, will help choose the supplier of downloads and decide on the overall strategy for working with partnerkami. The main advantages :

1. The speed and delivery. Average up-to medium-speed downloads of 1.5 letters per second from one spamyaschego bots, 2 to bots spamyat at speeds of 3000 letters per second, equal to 10 leading to millions of messages delivered per hour. This average figures for good loading each bot could spamit up to 3.5 letters per second.

2. The persistence of bots. Botha bypass all the latest version of anti-virus and faervollov, including the latest version of Zone Alarm, Outpost, Kaspersky, and the bot rigidly set in the system so that they are impossible to remove, even in safe mode. All innovation and refinement, we test drivers bots not only stands the test on different versions of the OS, but also on actual downloads from various suppliers. Cleaning loadera happens every day.

3. Convenience work, and further opportunities for constant refinement. We make the process convenient and efficient spam, the whole routine in the most automated, the time our customers spend at statov refresh. However, if you or your staff would like to have enough knowledge to extract the maximum from their bots and bases, you have a beautiful high-tech istrument it may izmennie any settings.

4. Business centers, skilled technical support. Complex program complex, which is fully explored - unique challenge, our support team will help you in any questions and solve any problems.

5. Flexible pricing policy. Our command is spam many years in different directions, and our customers are top-sellerami many partnerships programs we are familiar with the process of naslyshke not spam. With this experience and knowledge, we do your business more stable and profitable. Our tariff plans:

1-2 servers - $ 4000 per server
3-5 servers - $ 3000 per server

Let's summarize the key points :

- a "spamming appliance" comes with 2500+ zombie bots, capable of sending 7000 emails per second
- built-in verification for detection against common spam scoring systems
- managed anti virus bypassing capabilities and signatures based detection
- technical support

What's next to come? Possibly a USB stick with built-in C&C to a botnet with full admin rights. Continue reading →

A Journey to the Heart of Internet Censorship

Reporters Without Borders just released their latest report on China's Internet Censorship practices, outlining how exactly bureaucracy intersects with technology, perhaps the worst combination I could think of :

"The report also documents how the Beijing Internet Information Administrative Bureau has in practice asserted its daily editorial control over the leading news websites based in the nation’s Capital. It gives many examples of the actual instructions issued by officials in charge of this bureau. The last part of the report gives the results of a series of tests conducted with the mechanism of control through filtering keywords. These tests clearly show that, though there are still many disparities in the levels of censorship, the authorities have successfully coerced the online media into submission to censor themselves heavily on sensitive subjects."

Information is not free, but it just wants to be free and you cannot control the rules of curiosity and the basic right to know who's what and what's when -- even if you shut down the Internet access inside the country. China's Internet censorship is on the other hand a driving force for academic research across the globe. Even wondered what are the latest blocked keywords discovered filtered over time? Try the list of blacklisted keywords discovered by ConceptDoppler, as of 19 Sep 2007, part of the ConceptDoppler project - A Weather Tracker for Internet Censorship.

Does This Blog Speak for Itself?

Before January 2007, I could only say that I'm glad to have you as a reader of this blog, but with the Talkr-ization of my blog during that month, I can now freely say I'm also glad to have you as both, a reader and a listener taking into consideration the interest in the audio versions of my analyses. It's great to follow the progress of the service and the efforts the folks behind it put into improving its quality. I can only hope that they reach Ms. Dewey's speech engine, even go beyond it by allowing customization in the form of different voices to choose from.

Moreover, all the readers who are interested in reading this blog on a mobile device, can do so via a newly started service called MoFuse that I'm using as of recently :

"MoFuse is short for Mobile Fusion. MoFuse was founded in July of 2007 and released it's first private beta in late September of 2007. MoFuse allows content publishers to create RSS driven mobile sites and gives our users the ability to control almost every aspect of the design using some of our AJAX features."

Enjoy!

Fast-Flux Spam and Scams Increasing

As I pointed out in my last series of posts assessing pharmaceutical scams and phishing campaigns, both, botnet masters, pharma masters, and rock phishers, are starting to take advantage of fast-flux networks to make it harder to trace back and shut down their operations. Here's a related article on the topic :

"With fast-flux, spammers continually change the URL in the e-mail to counter filtering efforts. The constant change requires a corresponding defense that recognizes those changes as they occur, Red Condor officials said. Fast-flux botnets turn IP addresses against anti-spammers. Using a large number of servers, fast-flux DNS uses a compromised PC as a proxy, frustrating investigators. In its September intelligence report, MessageLabs counted fast-flux DNS techniques as one of the key reasons botnets are hard to shut down. The MySpace worm that compromised thousands of MySpace users' sites earlier this year utilized fast-flux techniques."

Let's showcase this emerging trend. Take for instance some recently spammed .cn domains such as considerjust.cn and pageagainst.cn advertising a Canadian Pharmacy scam. The domains have an allocated space of IPs to rotate on each and every request to them, something you can easily verify by pinging them and see how their IPs change on every new ping in coordination with the allocated IP table you can see in the screenshot. It gets even more interesting, especially in terms of locating the main fast-flux domain, in this case it's mainseven.com, a central point for a great deal of other pharma domains in its fast-flux. Here are graphs of fast-flux spam and scam networks :

mainseven.com

aaapills.org

comproper.com

lovelypills.com

fonteay.com

drugslovetown.com

abcmeds.org

As in every other competitive industry, pretty much all the market participants such as botnet masters, pharma masters, spammers and scammers, follow what the others are doing and by taking notice in which practices the others outperform them, figure out how to apply them within their practices at a later stage - competitive benchmarking within the underground ecosystem is already a fact.

Compromised Sites Serving Malware and Spam

Wish it was the average .cn domain I'm referring to, in this case it's the web sites of three U.S towns, namely the City of Chetek, Winsonsin, the City of Somerset, Texas and Town of Norwood, Massachusetts, who are the latest victims of embedded malware and blackhat SEO injected within their juicy from a blackhat SEO perspective .gov tld extensions.

Apparently, malicious parties managed to compromise City of Chetek's official site and created several subdomains with URLs consisting of spam redirecting to the downloader's page :

st-3.x.cityofchetek-wi.gov/porn/st3/502.html
st-3.x.cityofchetek-wi.gov/porn/st3/537.html
st-2.x.cityofchetek-wi.gov/porn/st2/322.html
2k.x.cityofchetek-wi.gov/porn/2k-003/1618.html
st-2.x.cityofchetek-wi.gov/porn/st2/409.html

The following URLs redirect to the downloader : freeclipoftheday.com/movie1.php?id=4154&n=teens&border=FFFFFF&bgcolor=000000

Detection rate : Result: 9/32 (28.13%)
File size: 75771 bytes
MD5: a74b09c7e6ca828ec0382c4f4f234bac
SHA1: 2861a4215dd2a579afe1e30372e05d2ea00223f2

City of Somerset, Texas official site is also embedded with the same blackhat SEO content structure, which leads me to the conclusion that these two are related :

2k.x.somersettx.gov/porn/2k-004/156.html
2k.x.somersettx.gov/porn/2k-004/313.html
2k.x.somersettx.gov/porn/2k-004/829.html
2k.x.somersettx.gov/porn/2k-004/830.html
st-5.x.somersettx.gov/porn/st5/103.html

Town of Norwood, Massachusetts :

sql.norwood-ma.gov/libraries/transformations/.dir/132/valium-cost.html

ldap.norwood-ma.gov/htdocs/js/.dir/12/valium-online-order.html

Several more high profile sites hosting such scams I came across to yesterday are NASA's Worldwind, and the State of New Jersey that used to historically host such pages :

issues.worldwind.arc.nasa.gov/secure/attachment/10781/Buy-Valium.html
issues.worldwind.arc.nasa.gov/secure/attachment/10800/Valium.html
issues.worldwind.arc.nasa.gov/secure/attachment/10791/Panasonic-Ringtone.html

nj.gov/education/voc/9/2007/
nj.gov/education/voc/9/2007/viagra/viagra-online.html
nj.gov/education/voc/9/2007/zoloft/buy-zoloft-online.html
nj.gov/education/voc/9/2007/tramadol/discount-tramadol.html

Moreover, during the last week, another pack of sites were also reported to serve malware, spam, and blackhat SEO pages on their servers :

Collateral Damage: CA County Site Redirects to Porn, Countermeasure Causes Major Hassle

Arizona Government University Site: Hacked!

Calipornication… Again

Bank of Ghana, others, compromised

Brookhaven National Labs hacked, serving porn

Just yesterday for instance, F-Secure discovered a phishing page hosted at India's Police Academy site, and
Sunbelt pointed out that Beer.ch got IFRAME-ed with the following URLs belonging to the Russian Business Network who also IFRAME-ed Bank of India once :

81.95.149.74/1/index.php

81.95.149.74/22/index.php

How is all this happening? In both, automated, and sometimes targeted way, where automated stands for remote file inclusion through botnets.

I sure know all the pharmaceutical blockbusters now.

Incentives Model for Pharmaceutical Scams

Sometimes, it's unbelievable how easy is in fact to social engineer people on their way to "make a deal" online, especially when buying pharmaceuticals online. Let's discuss organized pharmaceutical scams the way I perceive them, which like phishing also aim at reaching the efficiency level.

It's a public secret that Amazon.com's success in terms of sustained profitability has to do with their affiliation based model, namely "let the others do the sale for you". Pharmaceutical scammers have been anticipating this model for quite some now, a model where the pharma masters forward the processes of collecting potential customers (emails harvesting), contacting them and letting them know of how cheap their pharmaceutical are (spamming), enticing them to initiate a transaction with a fancy and professionally looking like site (freely available pharmacuitical web site templates) to those who become part of an affiliate network like the one you can see in the screenshot.

Pharmaceutical scammers have their own fast-flux networks of constantly changing domain and IP addresses, shared hosting of multiple scams in different segmets. Remember meds247.org? It's still up and running but the javascript obfuscation I reviewed before is now pointing to web server's directory whose main index hosts a p0rn site - center4cares.com, so you have a p0rn site that's hosting viagra propositions - "insightful". Moreover, pharmacuitical scam campaigns are also known to use free web space providers as doorway pages in the form of redirectors. For instance, the most recent spamming campaign promoting a Canadian Pharmacy scam located at rxlovecaptain.com, is taking advantage of the already established trusted brand of Geocities to redirect the spammers users to the main page :

geocities.com/MorganLogan82
geocities.com/AishaDeleon78
geocities.com/CarsonNguyen93

If efficiency truly matters from a scammer's perspective, we may soon witness actual DIY marketing packages with templates, "collection of potential customers", and a list of services to use when "contacting them". Now, if the pharma masters want to diversify as well, they can vertically integrate by owning or renting the spamming services themselves, something I haven't come across to - yet.

Assessing a Rock Phish Campaign

The majority of Rock Phish campaigns usually take advantage of a single domain that's hosting numerous different phishing scams targeting different financial organizations. However, another trend is slowly emerging and that is the development of phishing domain farms, either taking advantage of a shared hosting as you can see in the graph on the left, or fast-fluxing the campaigns to increase the average time a phishing site remains online. Here's the interesting part acting as proof on the emerging trend of so called malicious economies of scale, and also, showcasing Rock Phish's effiency vs security trade off due to the centralization of the campaign on a single IP only. In this campaign we see a single IP (200.77.213.15) hosting 38 rock phish domains, that on the other hand in a typical Rock Phish style host multiple phishing pages targeting different companies.

Meanwhile, there's still a lot of confusion going on about what exactly Rock Phish is, and as you can see in this article, it's wrongly implied that it's some sort of a phisher's group :

"Nobody knows exactly who or what Rock Phish are -- whether it's one person or a group of people -- but security researchers believe Rock Phish is behind as many as half of all phishing attacks on the Web. Fast flux is a method by which a domain name that phishers use has multiple IP addresses assigned to it. The phishers switch those domains quickly between the addresses so that it's not as easy to find or shut down the phishing sites."

and another one :

"Of particular concern is an increase in “rock phishing,” originated by the Rock Phish Gang based in Eastern Europe. Rock phishers use stolen information to register and rapidly cycle through domain names and IP addresses. They obscure their origin with botnets, which automate unwitting consumers’ computers to send out spam."

In reality, Rock Phish is a script taking advantage of the now commoditized phishing pages of each and every web property and company that is a potential victim, hosted on a single domain in order to achieve efficiency. Once the script and the phishing pages are in the wild, the entry barriers into phishing scams become significantly lower allowing novice phishers to easily launch what used to a professional phishing campaign much easier than ever.

Why give the kid a phish, when you can teach them to phish?

People's Information Warfare Concept

Malicious Culture of Participation

DoS battle stations operational in the name of the "Please, input your cause". Preventing a malware infection in order to limit the possibility for the host to become part of a botnet that will later one start a large scale DDoS attack is such a rational thinking that information warriors truly understanding what information warfare is all about, tend to undermine. The recently discussed "people's information warfare" concept highlighting China's growing interest in the idea, is a great example of a culture of participation orbiting around hacktivism cause, a culture we've also seen in many other hacktivism tensions in the past, and will continue to see in the future. The entire concept is relying on the fact that the collective bandwidth of people voluntarily "donating" it, is far more efficient from a "malicious economies of scale" perspective, compared to for instance the botnet masters having to create the botnet by infecting users in one way or another. Moreover, empowering an average Internet user with diversified DoS capabilities is directly increasing the nation's asymmetric warfare capabilities in an event of a hacktivism war.

Furthermore, the majority of DoS or DDoS flooding tools have a relatively high detection rate, but when people want to use them, they'll simply turn off their anti virus software, the one they use to prevent malware infections, but in a "people's information warfare" they can go as far as consciously becoming a part of a hacktivism centered botnet. Take this DoS tool featured in the screenshot for instance, it has a high detection rate only if the anti virus software is running, but in situation where a "malicious culture of participation" is the desired outcome it doesn't really matter. Donating their bandwidth and pretending to be malware infected is far more dangerous than botnet masters acquiring DDoS capability by figuring out how to infect the massess. It's one thing to operate a botnet and direct it to attack a certain site, and entirely another to be infected with a malware that's DDoS-ing the site, a situation where you become an "awakened and fully conscious zombie host".

Examples of the "People's Information Warfare Concept" :

- During the China/U.S hacktivism tensions in 2001 over the death of a Chinese pilot crashing into an AWACS, Chinese hacktivists released mail bombers with pre-defined U.S government and military emails to be attacked, thus taking advantage of the people's information warfare concept

- The release of the Muhammad cartoons had its old-school hacktivism effect, namely mass defacements of Danish sites courtesy of Muslim hacktivists to achieve a decent PSYOPS effect online and in real-life

- The Israel vs Palestine Cyberwars is a great example of how DIY web site defacement tools were released from both sites which resulted in a web vulnerabilities audit of the entire web space they were interested in defacing to spread hacktivism propaganda

- Cyber jihadists taking advantage of the "people's information warfare" concept by syndicating a list of sites to be attacked from a central location, and promoting the use of a Arabic themed DoS tool against "infidel" supporting sites

- What exactly happened during Russia's and Estonia's hacktivism tensions? The voting poll that is still available indicates that people believe it was botnet masters with radical nationalism modes of thinking. But judging from the publicly obtainable stats, ICMP often comes in the form of primitive DIY DoS tools compared to the more advanced attacks for instance. Collectivist societies do not need coordination because they know everyone else will do it one way or another.

Power to the people.

UPDATE:
Turkish hackers target Swedish Web sites - "Hackers in Turkey have attacked more than 5,000 Swedish Web sites in the past week, and at least some of the sabotage appears linked to Muslim anger over a Swedish newspaper drawing that depicted the Prophet Muhammad's head on a dog's body. Around 1,600 Web sites hosted by server-provider Proinet and 3,800 sites hosted by another company have been targeted, Proinet spokesman Kjetil Jensen said Sunday. Jensen said hackers, operating on a Turkish network, at times replaced files on the sites with messages."

DIY CAPTCHA Breaking Service

Given that spammers and phishers are already breaking, bypassing our outsourcing their CAPTCHA breaking needs, the introduction of a DIY (do-it-yourself) model provided confidence in the recognition process is over 80%, was inevitable. The CAPTCHA Bot is a good example of a recently released DIY CAPTCHA breaking service where the users feed their accounts with credits, sets URLs and CAPTCHA's to get recognized. If it were pitched at vendors or anyone out there maintaining a CAPTCHA as a service it would have been a great idea, trouble is, it would be largely abused in its current form. Let's discuss the incentives model. Are developers of CAPTCHAs interested in improving the security of their CAPTCHAs in the form of contests with financial rewards or job propositions for those who dare to break them in a contest form? Not necessarily, and fixing vulnerabilities whenever such appear is done in an "on demand" fashion like we've seen with Vladuz's Ebay CAPTCHA populator. CAPTCHAs at the most popular web services are the gatekeepers of their online reputation, else, the flood of splogs and malware embedded blogs, as well as spam and phishing emails coming from free web based email providers may outpace the current model.

CISRT Serving Malware

The Chinese Internet Security Response Team is reporting that it has found embedded IFRAMEs serving malware within some of its pages. And despite that the blog itself is now clean, Trend Micro are pointing out that the main index is still IFRAME-ed and that the attackers took advantage of the momentum during China's "Golden Week" holiday.

IFRAMEs at the main index lead to :

js.users.51.la/392481.js
51.la/?392481
img.users.51.la/392481.asp

IFRAMEs at the blog used to point to :

mms.nmmmn.com/99913.htm
mms.nmmmn.com/30000.htm
mms.nmmmn.com/11122.htm

and ganbibi.com - where the twenty password stealers for online games located at ads.ganbibi.com/100.exe to ads.ganbibi.com/120.exe in numerical order are still active.

The Dynamics of the Malware Industry - Proprietary Malware Tools

The Underground Economy's Supply of Goods and Services

The demand for private malware tools such as crypters, loaders and droppers is in tact with the supply of such tools, a market model whose higher profit margins satisfy both the coder of the tool as the seller and the buyer who's willing to pay a higher price for an undetected malware tool compared to using the publicly available and therefore with a high detection rate ones. The seller's one-to-many market proposition may generate sales on a volume basis, but the more people have the malware tool in question, the more commoditized, thus ineffective and much easier to fall into the hands of an anti virus vendor or a researcher it gets. And so, proprietary malware tools started emerging, ones only a small amount of people have access to. Nowadays, the malware industry is slowly maturing to a services-oriented economy as the logical evolution from a products-centered one, further accelerating its dynamics and future growth. What follows once goods and services both mature as a concept? Outsourcing, which as a matter of fact is already happening.

The Invisible Hand of the Malware Coder

The concept of proprietary malware tools is a very interesting one mainly because the coders of the malware tools are exercising control over the supply and distribution of the malicious goods in order to earn a higher return on investment, and ensure the customer gets the best product ever, one that must remain undetected for as long as possible. In respect to the distribution, it's sort of a self-regulation issue mainly because the buyer that spent a significant amount of money to obtain the latest malware tool will not leak it online and turn it into a commodity. As for the seller, he's ensuring that the tool will be sold to, for instance, five different people, no more and no less, since the perceived value and coder-added exclusiveness will result in a very high profit margin.

The market gets even more dynamic with the possibility for the buyer to exchange the malware tool he obtained at the over-the-counter market, and by doing so to limit the tool's exclusiveness, risk to have its value come close to zero if it leaks online, and most interestingly, his actions would have a butterfly effect on the other four people that hypothetically paid a higher profit margin price to obtain it. Given that the seller is interested in a higher profit margin only, he could either increase it and sell it to less than five people thinking that the less people have it the lower the chance it will leak or get exchanged, or if customer satisfaction and long-term relationships matter come up with a strategy on how to ensure the tools remain exclusive, though educating his customers for instance.

Images of crypters and joiners are samples of currently available proprietary malware tools for sale.

Love is a Psychedelic Too

Compared to a previous example of an over-performing image spammer whose efforts to bypass spam filters make it virtually impossible for someone to fall victim into the pharmaceutical scam, in this example of image spam we have something very interesting, namely a dynamic subdomain generating spamming host running a proxy server every time the central campaign URL gets refreshed via an obfuscated javascript. meds247.org (216.55.70.170) is the public face of abetterlevel.org (221.130.192.17), and here are examples of the "one-time-scams-in-everything" style subdomains :

cpv9c5pt.abetterlevel.org:8080/cg/viagra.php

ccj70tjcm.abetterlevel.org:8088/cg/viagra.php

fdbtpju.abetterlevel.org:8080/cg/viagra.php

b80cpno.abetterlevel.org:8088/cg/viagra.php

ffh3rj8zn.abetterlevel.org:8088/cg/viagra.php

Once accessed, a few minutes later the subdomains either stop responding, or start listening on the second port. Moreover, all the subdomains generated at abetterlevel.org resolve to radius.tercernivel.com (200.57.39.20) an indication of an ecosystem operating on three different networks.

Don't Play Poker on an Infected Table

The scammy Euro VIP Casino is making another round this afternoon and trying to entice the spammed European users into downloading its software by promising $400 as a welcome bonus. Needless to say you ought to ignore it. Here's a full list of the typosquatted domains serving the scams.

Online gambling is a buzz Internet activity allowing malicious parties to enjoy the "pull effect" by end users who themselves look for and download such applications. In this spamming campaign, however, we have a combination of a "push" approach, segmentation targeting European users, social engineering in the form of a promotion, and typosquatting. The first campaign (SetupCasino.exe) is currently hosted in China (116.199.136.29) on a host managing a second online gambling scam campaign impersonating Golden Gate Casino (SmartDownload.exe) under the following domains topgamecasino.net; superroyalcasino.com; nlymycasino.cn; lookforcasino.cn Continue reading →

Zero Day Vulnerabilities Market Model Gone Wrong

It's one thing to allow legitimate buyers, presumably the affected vendors themselves to bid for a zero day vulnerability discovered within their products in order to provide financial incentive for the researcher that discovered the flaw, another to superficially increase the monetary value of a zero day vulnerability taking advantage of its vendor-added exclusiveness, but entirely another to position responsible disclosure as an exclusive courteousness. Here's a sample letter informing the company within whose products a vulnerability has been found, and yes, the ultimatum for not releasing it :

"We've discovered an attack against the LinkedIn toolbar. If you are interested in the bug, we would like to give first right of refusal to purchase it. We'd also like to perform a more complete security audit of your products. We can help make the LinkedIn products more secure," DeMott stated in e-mail sent to LinkedIn on July 10, as viewed by CNET News.com. The e-mail continues: "If you wouldn't like to buy it then we are happy to resell or release as a full disclosure to help prevent security issues arising on end users servers. We strongly believe in keeping users safe. We are unique in that we give vendors a first chance at the bugs we discover rather than selling to a third-party or releasing publicly. Please find the VDA Labs Value add document attached. If you'd like to buy the bug we will provide working attack code, so that you can verify the bug, before you send the check." VDA set a deadline of July 17 and requested a payment of $5,000."

I first mentioned the possibility of having a security researcher blackmail an affected party a long time ago, however, I never thought it would be a company with serious knowledge in the field that's setting ultimatums, doubling the requested amount for the vulnerabilities if the vendor delays the response and threatening to release a PoC in a full disclosure style. Getting paid for getting hacked in reverse order - getting hacked for not paying. However, the ugly reality goes that what's a zero day for the mainstream media today is last month's zero day for the underground that's been improving the chances of success of their targeted attacks against a specific company or an individual. That's of course in the rare cases when malware authors no longer keep it simple, the stupids.

Here's another article on this story. Image courtesy of eEye's Zero Day Tracker. Continue reading →

DIY Chinese Passwords Stealer

This DIY passwords stealer courtesy of a chinese hacking group is pitched as Vista Compatible, with a server size in less than 20kb, process injection, form grabbing and password stealing capabilities for anything keyloggable, anti virus software killing capabilities, and uploading of the results to a central location, in this particular case an example is given for notification via Tencent, China's main IM network. More info :

"Backdoor.Hupigon.GEN has rootkit functionality. It injects itself into Internet Explorer causing IE to hide itself. It also logs keystrokes and sends this information to remote servers."

Detection rate of the builder: Result: 15/32 (46.88%)
File size: 267213 bytes

SHA1: 78f855843d312ab76e1f8f0b912bd475781a8864

Here are several more recent releases by Chinese hacking groups, as well as a comment on the big picture. Continue reading →

A New DDoS Malware Kit in the Wild

On the majority of occasions, malware authors either put efforts into implementing a set of standard features within a malware enabling them to send out spam, use the already infected hosts as future infection and propagation vectors, or entirely outsource the features by releasing the malware as open source one. On the other hand, certain malware authors seem to avoid diversification and tend to stick to core competencies only, in this case a DDoS ready infected host as its only function, thereby decreasing the file size of the malware and sort of improving its stealthiness by putting the infected host in a passive "on demand" state compared to a situation where the host is already sending out spam and phishing emails could be much more easily identified as an infected one and its DDoS capability could turn irrelevant due the malware's multi tasking activities.

This specific DDoS malware kit currently offered for sale includes the standard firewall bypassing and rootkit capabilities, in between offering the possibility for zero day malware on demand once previous instances of the bot in question achieve a high detection rate. Moreover, in between providing custom DDoS capabilities like the ones I discussed in a previous post, it's yet another indication of the ongoing Web-ization of botnet communications which I think is about to replace the default use of the IRC command and control in the long term.

Syrian Embassy in London Serving Malware

After Bank of India was serving malware in August, next to the U.S Consulate in St.Petersburg two days later in September, now the Syrian Embassy in London is the latest victim of a popular malware embedding attack which took place between the 21st and 24th of September. As obfuscating the IFRAMEs in order to make it harder for a security researcher to conduct CYBERINT is about to become a commodity with the feature implemented within the now commoditized malware kits, it's interesting to note that in this particular attack the attackers took advantage of different javascript obfuscations, and that once control of the domain was obtained, scam pages were uploaded on the embassy's server. The embassy had recently removed the malicious IFRAMEs, but the third one remains active acting as a counter for the malicious campaign.

Which domains act as infection vectors?

sicil.info/forum/index.php and sicil.info/g/index.php (203.121.79.71) using patched vulnerabilities exploited in the usual MPack style :

function setslice_exploit

function vml_exploit

function firefox_exploit

function firefox1_exploit

function wmplayer_exploit

function qtime_exploit
function yahoo_e

function winzip_exploit

function flash_exploit

function w2k_ex

0ki.ru/forum/index.php (80.91.191.224) where a WebAttacker launches several other exploits, and x12345.org/img/counter.php?out=1189360677 (66.36.243.97)

What are the malware authors trying to infect the visitors with?

A Banker Trojan with a low detection rate :

BitDefender 2007.09.28 BehavesLike:Win32.ProcessHijack

Ikarus 2007.09.28 Trojan.Delf.NEB

Think malware authors were virtually satisfied to only have the visitors infected with the malware? Not at all. This is perhaps the first but definitely not the last time I see an embassy hosting pharmaceutical scam pages and ring tone ones. List of historically hosted scam pages :

UPDATE :

The folks at ScanSafe contacted me to point out that they've discovered the malware at the Syrian embassy on the 12th of August providing us with more insights on how long the attackers had access to the embassy's site. In ScanSafe's example, different malicious URLs (miron555.org/s/index.php) were rotated compared to the ones used during 21/24 of September. And given the embassy's site states it was last updated in 2005, cleaning it up and ensuring the attackers no longer have access to it may take a while.

A New Issue of (IN)Secure Magazine "in the Wild"

(IN)Secure Magazine's Issue 13 was released yesterday, and as always is definitely worth printing out. What is (IN)Secure Magazine? (IN)Secure Magazine is the type of "too good to be for free" kind of publication, covering the information security industry, the newly emerging technologies and threats, as well as the people who put it all together.

It's also great to note that my blog has been featured in their new section at page 62, an indication for an upcoming flood of an even more quality audience, and a personal incentive to contribute to a future issue of the magazine with a qualitative research on zero day vulnerability markets I've been working on for a while.
