Wild Wild Underground

April 25, 2006
Where's the real underground these days, behind the shadows of the ShadowCrew, the revenge of the now, for-profit script kiddies, or in the slowly shaping real Mafia's online ambitions? Moreover, is all this activity going on behind the Dark Web, or the WWW itself? Go through this fresh overview, emphasizing on today's script kiddies, 0days as a commodity, malware and DDoS on demand on the WWW itself, and perhaps a little bit of vendors' tolerated FUD.








In a previous post, I mentioned on the existence of the International Exploits Shop, the Xshop, basically a web module where 0days, and service support in terms of videos, PHP-based configuration etc. are provided to anyone willing to get hold of a 0day/zero-day vulnerability -- scary stuff, yet truly realistic concept that's directly bypassing today's infomediaries that purchase vulnerabilities.








I must admit I didn't do homework well enough to figure out that the Hack Shop has been changing quite some places for the last two years and having offered many other vulnerabilities, going beyond what I came across to two months ago -- the Internet offers a much wider set of potential buyers than from the three informediaries for the time being. As a reader gave me a hint, in the future images would protect that type of pages from crawling activities, and it's interesting to note that previous versions of the shop were doing exactly the same, while the last one I got tipped about, was using text on its pages. What's also important to mention is that these are the public propositions, ones placed on the WWW, and not the Dark Web, the one behind closed doors. Last month, Sophos mentioned on the existence of a multi-exploit kit for an unbelievably cheap price :








"A Russian website is selling a spyware kit for $15. The website promises an easy-to-deploy spyware that only requires users to trick their victims into visiting a malicious website. The website even offers technical support. Carole Theriault, senior security consultant at Sophos, says such websites invite script kiddies and other unskilled would-be hackers into the world of cybercrime for profit."







Rather interesting, WebSense Security Labs looked further, came up with the screenshots from the site itself, cut the last screenshot you can clearly see here (Disable adobe acrobat web capture, Disable opera user, Kill frame, Location lock, Referrer lock) but again spread the rumour of multi-exploit kit for sale at $15, of course for entering the for-profit cyber crime business -- a little bit of FUD, sure, but the sellers aren't still that very desperate I think.



So, I decided to look even further and now can easily conclude -- it depends where you're buying it from, I mean even the official site sells it at a price that way too high for an average script kiddie to get hold of multi-exploits pack -- whether outdated or not can be questioned as well. So, the kit officially goes for $300 and, $25 for updates, I also came across it for $95, but I bet they are a lot of people looking for naive wannabe exploiters out there. As you can see on these screenshots, it has the ability to encrypt HTML pages, parts of the page, and take precautions for curious folks trying to figure out more about the page in question, and it makes me wonder on how well would malicious HTML detection would perform here, if it does?








What's the outcome -- script kiddies with attitude are basically compiling toolsets of old exploits and building all-in-one malware kits. As you can even see, they are lazy enough not to keep an eye on its detection status, a sign of "growing" business for sure, yet the "underground" seems to Ph34r going to the Opera , so take your note.








I recently came across to a great article "The Return of the Web Mob" you can find more details on the topic as well, such as :








"I saw one case where an undetectable Trojan was offered for sale and the buyers were debating whether it was worth the price. They were doing competitive testing to ensure it actually worked as advertised," said Jim Melnick, a member of Dunham's team."








"In November 2005, Mashevsky discovered an attempt to hijack a botnet. [The] network of infected computers changed hands three times in one day. Criminals have realized that it is much simpler to obtain already-infected resources than to maintain their own botnets, or to spend money on buying parts of botnets which are already in use," he said."








"Dunham, who frequently briefs upper levels of federal cyber-security authorities on emerging threats, said there have been cases in Russia where mafia-style physical torture has been used to recruit hackers. If you become a known hacker and you start to cut into their profits, they'll come to your house, take you away and beat you to a pulp until you back off or join them. There have been documented cases of this," Dunham said."








While doing a recent research across the Russian and the Chinese domain, I came to the conclusion that every local scene has it's own underground, and that those that go as publicly as some do at the bottom line, make the headlines. However, Chinese users being collectivists, are still at the heroic stage of cyber dissidents slowly turning into wannabe hackers, and they have a chain of command, so to speak, that I can argue is more powerful than thought to be "well organized" like the ones in Russia, being individualists. There are even marketing campaigns going on in the form of surveys, trying to measure the bargaining point for 0day vulnerabilities I guess. This one says :



How much would you be willing to pay for an exploit?
$100-300
$300-500
$500-1000
over $1000
we write our own exploits :D
I get them for free








and offers trying to even add value to the purchase by offering a SMS flooder for free if you purchase the exploit. I mean, if you start thinking logically, bypassing the current intermediaries and their moody programs compared to one-to-one communication model with a possible buyer -- the entire idea behind disintermediation is the method of choice. Have 0days turned into an uncontrolled commodity that has to be somehow, at least, coordinated?!








In my recent Future trends of malware research, I mentioned how open-source malware would inevitably dominate, and how the concept will put even more pressure on AV vendors to figure out how to protect from unknown malicious code -- proactively. What I came across to was, customer-centric malware propositions, special features increase or decrease the final price, botnet sources for free download/purchase if modifications are made, free advices coming with the purchase, on demand vulnerabilities, spamming or spam harvesting services on demand, price comparison for malware samples, rootkits-enabled pieces of malware indeed show an increase of growth, DDoS on demand services are usually proposed with 30 mins of service "demo".






Bot's sources are also annoyingly available at the click of a button, as I verified over 20 working links with archives averaging 75MB.








Popular ones :
urxbot, spybot, sdbot, rxbot, rbot, phatbot, litmus, gtbot, forbot, evilbot, darkirc, agobot, jbot, microbot, blueyebot, icebot, q8bot, happybot, htmlinfectbot, gsys, epicbot, darkbot, r00fuz, panicattack








Who's to blame? It's not Russia for sure, and if it was it would mostly have to do with enforcement of current laws, yet the global media tends to stereotype to efficiently meet deadlines, instead of figuring out what is going on at the bottom line. When the U.S sees attacks coming from Chinese networks, it doesn't mean it's Chinese hackers attacking the U.S, but could be that sick North Korean ones are trying to increase tensions by spoofing their identities. Moreover, as I've mentioned it is logical to conclude that there are "undergrounds" on a national level, for instance for the last couple of years there's been a steady growth of defacements and phishing attackers from Brazil, Turkey, and of course China, I rarely come across anything else but "mention Russia and get over it" attitude.






In respect to the Chinese "underground", according a report not to be disclosed, and so I'm not as it's fully loaded with impressive information, the Chinese underground back in 2002 used to aggressively attack U.S government's and military targets while drinking Coke from McDonald's themed Coke glass :) courtesy of the China Eagle Union themselves. Their actions in coordination with the Honker Union of China, for instance, played a crucial role in active hacktivism and continue playing it even today.


Like it or not, the average script kiddie, or can we say sophisticated Generation Y teenagers, are well too informed, and obviously sellers of malicious services such as DDoS and malware on demand, than it used to be years ago. I feel it's not their knowledge that's increasing, but the number of connected computers with security illiterate users aiming to put themselves in a "stealth mode" while online in order not to get hacked, or as a friend put it, running in root mode and hiding behind firewalls - ah, the end user.








You can digitally fingerprint a malicious code when you have it, that's normal, but what happens when you don't, can you fight the concepts themselves? Ken Dunham comments on "mafia-style physical torture" are the reflection of people naming their malware MyDoom and begging for botnets if you take your time to go through the quotes from Ancheta's case.








Don't ph34r the teenagers, ph34r their immaturity, and ongoing recruitment practices by the Mafia itself. Continue reading →

Where's my 0day, please?

March 07, 2006
A site I was recently monitoring disappeared these days, so I feel it's about time I blog on this case. I have been talking about the emerging market for software vulnerabilities for quite some time, and it's quite a success to come across that the concept has been happening right there in front of us. Check out the screenshots. The International Exploits Shop I came across to looks like this :



It appears to be down now, while it has simply changed its location to somewhere else. Google no longer has it cached, and the the only info on this wisely registered .in domain, can be found at Koffix Blocker's site.



A lot of people underestimate the power of the over-the-counter(OTC), market for 0day security vulnerabilities. Given that there isn't any vulnerabilities auction in place that would provide a researcher with multiple proposals, and the buyers with a much greater choice or even social networking with the idea to possibly attract skilled HR, the seller is making personal propositions with the idea to get higher exposure from the site's visitors. Whoever is buying the exploit and whatever happens with it doesn't seem to bother the seller in this case.



As there's been already emerging competition between different infomediaries that purchase vulnerabilities information and pay the researchers, researchers themselves are getting more and more interested in hearing from "multiple parties". Turning vulnerability research, and its actual findings into an IP, and offering financial incentives is tricky, and no pioneers are needed in here!



There's been a lot of active discussion among friends, and over the Net. I recently came across a great and very recent research entitled "Vulnerability markets - what is the economic value of a zero-day exploit?", by Rainer Boehme, that's worth the read. Basically, it tries to list all the market models and possible participants, such as :



Bug challenges
- Bug challenges are the simplest and oldest form of vulnerability markets, where the producer offers a monetary reward for reported bugs. There are some real-world examples for bug challenges. Most widely known is Donald E. Knuth’s reward of initially 1.28 USD for each bug in his TEX typesetting system, which grows exponentially with the number of years the program is in use. Other examples include the RSA factoring challenge, or the shady SDMI challenge on digital audio watermarking



Bug auctions
-Bug auctions are theoretical framework for essentially the same concept as bug
challenges. Andy Ozment [9] first formulated bug challenges in the terms of auction theory,
in particular as a reverse Dutch auction, or an open first-price ascending auction. This allowed him to draw on a huge body of literature and thus add a number of eciency enhancements to the original concept. However, the existence of this market type still depends on the initiative of the vendor



Vulnerability brokers
-Vulnerability brokers are often referred to as “vulnerability sharing circles”. These clubs are
built around independent organizations (mostly private companies) who oer money for new vulnerability reports, which they circulate within a closed group of subscribers to their security alert service. In the standard model, only good guys are allowed to join the club



-Cyber Insurance
Cyber-insurance is among the oldest proposals for market mechanisms to overcome the security market failure. The logic that cures the market failure goes as follows: end users demand insurance against financial losses from information security breaches and insurance companies sell this kind of coverage after a security audit. The premium is assumed to be adjusted by the individual risk, which depends on the IT systems in use and the security mechanisms in place.



Let's try define the market's participants, their expectations and value added through their actions, if any, of course.



Buyers
-malicious (E-criminals, malware authors, competitors, political organization/fraction etc.)
-third party, end users, private detectives, military, intelligence personnel
-vendors (either through informediary, or directly themselves, which hasn't actually happened so far)



Sellers
-reputable
-newly born
-questionable
-does it matter at the bottom line?



Intermediaries
-iDefense
-ZeroDayInitiative-Digital Armaments



Society
-Internet
-CERT model - totally out of the game these days?



As iDefense simply had to restore their position in this emerging market developed mainly by them, an offer for $10,000 was made for a critical vulnerability as defined by Microsoft. I mean, I'm sort of missing the point in here. Obviously, they are aware of the level of quality research that could be sold to them.


Still I wonder what exactly are they competing with :



- trying to attract the most talented researchers, instead of having them turn to the dark side? I doubt they are that much socially oriented, but still it's an option?



- ensuring the proactive security of its customers through first notifying them, and them and then the general public? That doesn't necessarily secures the Internet, and sort of provides the clientele with a false feeling of security, "what if" a (malicious) vulnerability researcher doesn't cooperate with iDefense, and instead sells an 0day to a competitor? Would the vendor's IPS protect against a threat like that too?



- fighting against the permanent opportunity of another 0day, gaining only a temporary momentum advantage?



- improving the company's clients list through constant collaboration with leading vendors while communication a vulnerability in their software products?



A lot of research publications reasonably argue that the credit for the highest social-welware return goes to a CERT type of a model. And while this is truly, accountability and providing a researcher with the highest, both tangible, and intangible reward for them is what also can make an impact. As a matter of fact, is blackmailing a nasty option that could easily become reality in here, or I'm just being paranoid?



To conclude, this very same shop is definitely among the many other active out there for sure, so, sooner or later we would either witness the introduction of a reputable Auction based vulnerabilities market model, or continue living with windows of opportunities, clumsy vendors, and 0day mom-and-dad shops :) But mind you, turning vuln research into IP and paying for it would provide enough motiviation for an underground 0bay as well, wouldn't it?

09.03.2006 - Two nice articles related to the issue appeared yesterday as well, "Black market thrives on vulnerability trading", from the article :



"Security giant Symantec claims that anonymous collusion between hackers and criminals is creating a thriving black market for vulnerability trading. As criminals have woken up to the massive reach afforded to their activities thanks to the Internet, hackers too are now able to avoid risking prison sentences by simply selling on their findings. Graeme Pinkney, a manager at Symantec for trend analysis, told us: 'People have suddenly realised that there's now a profit margin and a revenue stream in vulnerabilities... There's an element of anonymous co-operation between the hacker and criminal.'"



and "The value of vulnerabilities", a quote :



“ There are no guarantees, and therefore I think it would be pretty naive to believe that the person reporting the issue is the only one aware of its existence. That in itself is pretty frightening if you think about it. "
