      <content:encoded><![CDATA[<p><img class="alignright" style="float: right; border: 0; margin: 3px;" src="http://farm3.static.flickr.com/2052/2404940312_e759c4030d_m_d.jpg" alt="Locker" width="180" height="240" />Privacy is a lot like universal healthcare.  Many agree its a good idea in concept, but few people want to pay for it.</p>
<p>Richard Stallman - the man that gave us <a href="http://www.gnu.org/">GNU</a> - <a href="http://www.guardian.co.uk/technology/2008/sep/29/cloud.computing.richard.stallman">doesn&#8217;t trust Cloud providers with his data</a> and says you shouldn&#8217;t either.  Richard believes we should store our private data on our own computers using &#8216;free&#8217; (as in <a href="http://www.gnu.org/gnu/thegnuproject.html">freedom</a>) software.  The ironic part for Richard is that a significant portion of the Cloud is powered by open source software which he indirectly created (think <a href="http://gcc.gnu.org/">gcc</a>).</p>
<p>Richard sees it as a question of control.  Control is important but it isn&#8217;t the only variable.  Rather, I see it as a question of control, competence and economics.</p>
<p>The quick rebuttal to Richards&#8217; view is this: the average computer user is <a href="http://www.stallman.org/photos/rms-full-size.jpg">not as smart as you</a>.  Control is not the same as competence.  Control is about exercising choice, not about requiring everyone in the world to develop sufficient skills to protect complex hardware and software systems (aka their computer) against <a href="http://ddanchev.blogspot.com/">ever increasing threats</a>.</p>
<p>My view is that privacy is not &#8216;free&#8217;.  It comes at a cost.  Whether you run your own systems or rely on someone else to do it, there is a cost.  There is cost in designing and implementing mechanisms to support privacy.  Beyond upfront costs there are ongoing expenditures to ensure privacy is maintained e.g. maintaining access control lists, testing and applying security patches, data leakage prevention etc.  None of these things are &#8216;free&#8217;.</p>
<p>If we agree that privacy costs money then how much is your privacy worth?</p>
<p>Stop for a second - think of a number&#8230;  </p>
<p>Now did we all think of the <a href="http://pbskids.org/sesame/coloring/images/07_grover.gif">same number</a>?</p>
<p>The problem with a one size fits all approach to privacy is that we each place a different value on it.</p>
<p>Checking in on the <a href="http://epic.org/">EPIC</a> site, I saw this:  </p>
<blockquote><p>A new report from <a href="http://www.pewinternet.org/">Pew Internet and American Life Project</a> indicates that &#8220;cloud computing&#8221; applications, such as web-based email and other web apps, are raising new privacy concerns. The report <a href="http://www.pewinternet.org/press_release.asp?r=306" target="_blank">Use of Cloud Computing: Applications and Services</a> found that 69% of online Americans use webmail services, store data online, or use software programs such as word processing applications whose functionality is located on the web. At the same time, &#8220;users report high levels of concern when presented with scenarios in which companies may put their data to uses of which they may not be aware.&#8221; For example, 90% of respondents said that they &#8220;would be very concerned if the company at which their data were stored sold it to another party,&#8221; 80% say &#8220;they would be very concerned if companies used their photos or other data in marketing campaigns,&#8221; and 68% of &#8220;users of at least one of the six cloud applications say they would be very concerned if companies who provided these services analyzed their information and then displayed ads to them based on their actions.&#8221;</p></blockquote>
<p>What does that tell us?</p>
<p>The average (American) Internet user finds Cloud services convenient but has concerns about how their privacy might be affected by Cloud providers actions (duh!).  The survey identifies a lack of awareness in how private data is used in some consumer based Cloud services (consistent with web advertising awareness surveys).  </p>
<p>Unfortunately, the results of this survey are not very actionable.  The survey doesn&#8217;t mention whether these are all &#8216;free&#8217; Cloud services (we can only assume they are) or ask the respondents what their expectations of privacy are and how much they would be willing to pay for different privacy assurance levels. </p>
<p>On a sidenote, respondents were not asked if they had actually read the privacy agreement for the services they signed up to.  But the providers know if they did or not&#8230;  Or at least, they have the data to figure it out.  At sign up time they can measure the time between displaying the privacy agreement and the user clicking &#8216;I accept&#8217;.  If its just a few seconds then its pretty obvious there was more scrolling than reading going on.  But I think we can probably guess the answer without the data ;-).</p>
<p>I believe we need to be able to link expectation of privacy with cost.</p>
<ul>
<li>How much are you willing to pay for privacy?  What level of privacy assurance do you need?</li>
<li>How much is your Cloud Provider paying to protect your privacy today?  What privacy services could they reasonably offer if they had customers willing to pay?  How might this compare with how you manage your private data on your home computer today?</li>
</ul>
<p>The cynical view is that we expect privacy but don&#8217;t want to pay for it.  Its a bit like uptime - there is a parallel universe out there, where internal IT departments allegedly meet their 99.999% uptime SLAs, but when Gmail goes down, the Sergey Brin witchcraft dolls come out.</p>
<p>From a provider perspective, the &#8220;cost&#8221; of privacy invariably gets bundled under that line item called &#8216;Information Security&#8217;.  And don&#8217;t be fooled, the cost of privacy in reality is more than the salary of the person employed to be the privacy advocate (if there is one).  If we can&#8217;t see how much our providers are spending on our privacy then how can we judge if they are spending enough?  And what is enough?  And what can I get if I&#8217;m willing to pay a little extra?</p>
<p>Personally, I would rather we get some transparency around privacy costs and assessment of offerings.  However, without a sufficiently sized market of customers willing to pay for privacy assurance and Cloud Providers willing to be more open, I won&#8217;t hold my breath.</p>
<p>What about you?  Would you be prepared to pay for privacy?  Should providers be more transparent about what they do and don&#8217;t do and how they do it?<br />
 <br />

      <content:encoded><![CDATA[<p>We&#8217;ve known CAPTCHAs are insecure for some time, but now even the CAPTCHA-alternatives (often based on identifying cats from dogs or other animals) have proven insecure. Gmail, Windows Live hotmail and other popular sites were hacked as early as <a rel="nofollow" target="_blank" href="http://http://arstechnica.com/news.ars/post/20080415-gone-in-60-seconds-spambot-cracks-livehotmail-captcha.html">February</a>. Recently another defeat has come in the form of <a rel="nofollow" target="_blank" href="http://en.wikipedia.org/wiki/Xrumer">XRumer,</a> a <a rel="nofollow" target="_blank" href="http://arstechnica.com/news.ars/post/20081002-right-back-at-ya-captcha-bad-guys-crack-gmail-hotmail.html">spam bot</a> that posts messages on blogs and through email in order to boost search engine rankings.</p>
<p>What&#8217;s the solution? Ars Technica suggests there might not be a good one, in part because malware distributors can go so far as to hire real people to do their dirty work:</p>
<blockquote><p>Instead of trying to build better CAPTCHA-cracking programs, the malware industry went out and got itself some humans of its own. This effectively bypasses the primary security strength of the CAPTCHA system and leaves it entirely dependent on what we&#8217;ll call secondary security characteristics. CAPTCHAs are often complex (particularly these days), which does increase the chance that they&#8217;ll be misread (and returned incorrectly), while the font and display of the characters themselves are at least somewhat unfamiliar to the CAPTCHA crackers sitting on the other side of the world.</p></blockquote>
<p>Sometimes those captcha phrases are pretty incoherent to me too. When I post over at Craigslist sometimes it says I&#8217;ve gotten its Captcha wrong, and I end up wondering if secretly I&#8217;m a bot?? Apparently not a very smart one either.</p>]]></content:encoded>

That seems to be case with this spam campaign perfectly fitting into the "spam that made it through" category.<br />

The search queries lead to<b> galestay.com; housetear.com; callfold.com; richorbit.com</b> with several hundred spam domains participating in the campaign parked at <b>218.61.7.21</b> and <b>220.248.185.64</b>.<br />

Interestingly, the spammed through Yahoo emails never leave Yahoo Mail since it's only spamming Yahoo users according to the extensive number of emails CC-ed.<br />
<br />
What's to come in the long-term? With an entire spamming infrastructure build on the foundation of the hundreds of thousands of bogus accounts at legitimate services, spammers are already starting to embrace the "legitimate sender" mentality and<b> </b>are working on ways to integrate that infrastructure in their spam systems, evidence of which can be seen in several <a href="http://blogs.zdnet.com/security/?p=1899">different managed spamming services</a>.<br />

      <content:encoded><![CDATA[<div style="text-align: left;"></div><div class="separator" style="clear: both; text-align: center;"></div><a href="http://1.bp.blogspot.com/_wICHhTiQmrA/SL_ZoXre4vI/AAAAAAAACJ0/LKtKpSt0igQ/s1600-h/ddanchev_august.png" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" src="http://1.bp.blogspot.com/_wICHhTiQmrA/SL_ZoXre4vI/AAAAAAAACJ0/Phtgyl6rLXQ/s200-R/ddanchev_august.png" /></a>Following the previous summaries of <a href="http://ddanchev.blogspot.com/2008/07/summarizing-junes-threatscape.html">June's</a> and <a href="http://ddanchev.blogspot.com/2008/08/summarizing-julys-threatscape.html">July's threatscape</a> based on all the research published during the month, it's time to summarize August's threatscape.<br />
<br />
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.<br />
<br />
<b>01.</b> <a href="http://ddanchev.blogspot.com/2008/08/mcafees-site-advisor-blocking-nruns-ag.html">McAfee's Site Advisor Blocking n.runs AG - "for starters"</a><br />
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<br />
<br />
<b>02.</b> <a href="http://ddanchev.blogspot.com/2008/08/twitter-malware-campaign-wants-to-bank.html">The Twitter Malware Campaign Wants to Bank With You</a><br />
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<br />
&nbsp; <br />
<b>03.</b> <a href="http://ddanchev.blogspot.com/2008/08/compromised-web-servers-serving-fake.html">Compromised Web Servers Serving Fake Flash Players</a><br />
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<br />
<br />
<b>04.</b> <a href="http://ddanchev.blogspot.com/2008/08/pinch-vulnerable-to-remotely.html">Pinch Vulnerable to Remotely Exploitable Flaw</a><br />
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<br />
<br />
<b>05.</b> <a href="http://ddanchev.blogspot.com/2008/08/phishers-backdooring-phishing-pages-to.html">Phishers Backdooring Phishing Pages to Scam One Another</a><br />
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<br />
<br />
<b>06.</b> <a href="http://ddanchev.blogspot.com/2008/08/email-hacking-going-commercial-part-two.html">Email Hacking Going Commercial - Part Two</a><br />
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<br />
<br />
<b>07.</b> <a href="http://ddanchev.blogspot.com/2008/08/russia-vs-georgia-cyber-attack.html">The Russia vs Georgia Cyber Attack</a><br />
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.<br />
<br />
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.<br />
<br />
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 <a href="http://intelfusion.net/wordpress/?p=398">Social Network analysis of the cyberattacks</a> 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 <a href="http://blogs.nyu.edu/blogs/agc282/zia/2008/08/intelfusions_sna_of_russian_cy.html">happening in the "Dark Web" limiting the possibilities for open source intelligence</a> 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<br />
<br />
<b>08.</b> <a href="http://ddanchev.blogspot.com/2008/08/76service-cybercrime-as-service-going.html">76Service - Cybercrime as a Service Going Mainstream</a><br />
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 <br />
<br />
<b>09.</b> <a href="http://ddanchev.blogspot.com/2008/08/whos-behind-georgia-cyber-attacks.html">Who's Behind the Georgia Cyber Attacks?</a><br />
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.<br />
<br />
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.<br />
<br />
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.<br />
<br />
<b>10.</b> <a href="http://ddanchev.blogspot.com/2008/08/guerilla-marketing-for-conspiracy-site.html">Guerilla Marketing for a Conspiracy Site</a><br />
Conspiracy theorists may in fact have a new wallpaper to show off with<br />
<br />
<b>11.</b> <a href="http://ddanchev.blogspot.com/2008/08/banker-malware-targetting-brazilian.html">Banker Malware Targeting Brazilian Banks in the Wild</a><br />
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&nbsp; <br />
<br />
<b>12.</b> <a href="http://ddanchev.blogspot.com/2008/08/compromised-cpanel-accounts-for-sale.html">Compromised Cpanel Accounts For Sale</a><br />
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 <br />
<br />
<b>13.</b> <a href="http://ddanchev.blogspot.com/2008/08/diverse-portfolio-of-fake-security.html">A Diverse Portfolio of Fake Security Software - Part Two</a><br />
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<br />
<br />
<b>14.</b> <a href="http://ddanchev.blogspot.com/2008/08/diy-botnet-kit-promising-eternal.html">DIY Botnet Kit Promising Eternal Updates</a><br />
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<br />
<br />
<b>15.</b> <a href="http://ddanchev.blogspot.com/2008/08/diverse-portfolio-of-fake-security_20.html">A Diverse Portfolio of Fake Security Software - Part Three</a><br />
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<br />
<br />
<b>16.</b> <a href="http://ddanchev.blogspot.com/2008/08/fake-celebrity-video-sites-serving.html">Fake Celebrity Video Sites Serving Malware - Part Two</a><br />
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<br />
<br />
<b>17.</b> <a href="http://ddanchev.blogspot.com/2008/08/web-based-botnet-command-and-control.html">Web Based Botnet Command and Control Kit 2.0</a><br />
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"<br />
<br />
<b>18.</b> <a href="http://ddanchev.blogspot.com/2008/08/diverse-portfolio-of-fake-security_25.html">A Diverse Portfolio of Fake Security Software - Part Four</a><br />
Keep it coming, we'll keep it exposing until we end up getting down to the "fake software vendor" itself<br />
<br />
<b>19.</b> <a href="http://ddanchev.blogspot.com/2008/08/automatic-email-harvesting-20.html">Automatic Email Harvesting 2.0</a><br />
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<br />
<br />
<b>20.</b> <a href="http://ddanchev.blogspot.com/2008/08/fake-porn-sites-serving-malware-part.html">Fake Porn Sites Serving Malware - Part Three</a><br />
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<br />
<br />
<b>21.</b> <a href="http://ddanchev.blogspot.com/2008/08/facebook-malware-campaigns-rotating.html">Facebook Malware Campaigns Rotating Tactics</a><br />
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<br />
<br />
<b>22.</b> <a href="http://ddanchev.blogspot.com/2008/08/fake-security-software-domains-serving.html">Fake Security Software Domains Serving Exploits</a><br />
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<br />
<br />
<b>23.</b> <a href="http://ddanchev.blogspot.com/2008/08/exposing-indias-captcha-solving-economy.html">Exposing India’s CAPTCHA Solving Economy</a><br />
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. <br />
<br />
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<div class="feedflare">

<p>A year ago in September 2007, I (Dan York) spoke at Astricon 2007 in Arizona, USA, about &quot;Hacking and Attacking VoIP Systems: What You Need To Worry About&quot; My presentation covered a lot of the typical VoIP security threats, tools and best practices but also expanded a bit into specific security issues with Asterisk.&nbsp; Please do keep in mind that it has been a year since this presentation and so some of the issues I mention have been addressed. (<a href="http://www.astricon.net/">Astricon</a>, for those who don't know, is an annual developer conference for those who work with the <a href="http://www.asterisk.org/">Asterisk open source telephony platform</a>. Astricon 2008 is, in fact, coming up in about 3 weeks but I will not be attending this year.)

<p><strong>Show Content:</strong></p> 
<p>A year ago in September 2007, I (Dan York) spoke at Astricon 2007 in Arizona, USA, about &quot;Hacking and Attacking VoIP Systems: What You Need To Worry About&quot; My presentation covered a lot of the typical VoIP security threats, tools and best practices but also expanded a bit into specific security issues with Asterisk.&nbsp; Please do keep in mind that it has been a year since this presentation and so some of the issues I mention have been addressed. (<a href="http://www.astricon.net/">Astricon</a>, for those who don't know, is an annual developer conference for those who work with the <a href="http://www.asterisk.org/">Asterisk open source telephony platform</a>. Astricon 2008 is, in fact, coming up in about 3 weeks but I will not be attending this year.)

<p>Production assistance on this Special Edition was provided by Michael Graves who had a very tough task given the poor quality of the recording that I gave to him!&nbsp; Kudos to Michael for getting it to sound as good as it does.

Speculations around one of the main weaknesses of CAPTCHA based authentication in the face of human CAPTCHA solvers, seems to have evolved into a booming economy in India during the past 12 months, with thousands of people involved.<br />
<br />
The following article - "<a href="http://blogs.zdnet.com/security/?p=1835">Inside India’s CAPTCHA solving economy</a>" aims to expose legitimate data entry workers, whose business models and techniques are in fact used by Russian cybercriminals not only for personal phishing, spamming and malware spreading purposes, but also, to resell the bogus accounts and earn a premium in the process :<br />
<br />
"<i>No CAPTCHA can survive a human that’s receiving financial incentives for solving it, and with an army of low-wagedIndia CAPTCHA breakers human CAPTCHA solvers officially in the business of “data processing” while earning a mere $2 for solving a thousand CAPTCHA’s, I’m already starting to see evidence of consolidation between India’s major CAPTCHA solving companies. The consolidation logically leading to increased bargaining power, is resulting in an international franchising model recruiting data processing workers empowered with do-it-yourself CAPTCHA syndication web based kits, API keys, and thousands of proxies to make their work easier, and the process more efficient.</i>"<br />
<br />
Cybercrime is just as outsourceable as CAPTCHA breaking is these days.<br />
