    Banking on Badb in the Underweb

    Underground Web sites can be a useful barometer for the daily volume of criminal trade in goods like stolen credit card numbers and hijacked PayPal or eBay accounts. And if the current low prices at one of Underweb’s newer and more brazen card shops are indicative of a trend, the market for these commodities has never been more cutthroat.

    Visa, Amex cards for sale at Badb.su

    Badb.su is distinguishable from dozens of underground carding shops chiefly by its slick interface and tiny domain name, which borrows on the pseudonym and notoriety of the Underweb’s most recognizable carder. It’s difficult to say whether “Badb” himself would have endorsed the use of his brand for this particular venture, but it seems unlikely: The man alleged by U.S. authorities to be Badb — 29-year-old Vladislav Anatolievich Horohorin — has been in a French prison since his arrest there in 2010. Authorities believe Horohorin is one of the founding members of CarderPlanet, a site that helped move millions of stolen accounts. He remains jailed in France, fighting extradition to the United States (more about his case in an upcoming story).

    Badb.su’s price list shows that purloined American Express and Discover accounts issued to Americans cost between $2.50 and $3 apiece, with MasterCard and Visa accounts commanding slightly lower prices ($2-$3). Cards of any type issued by banks in the United Kingdom or European Union fetch between $4-$7 each, while accounts from Canadian financial institutions cost between $3 to $5 a pop.

    The site also sells verified PayPal and eBay accounts. Verified PayPal accounts with credit cards and bank accounts attached to them go for between 2-3$, while the same combination + access to the account holder’s email inbox increases the price by $2. PayPal accounts that are associated with bank and/or credit accounts and include a balance are sold for between 2 and 10 percent of the available balance. That rate is considerably lower than the last PayPal underground shop I reviewed, which charged 8 to 12 percent of the total compromised account balance.

    Verified PayPal accounts with positive balances sell for between 2-10% of the available balance.

    Ebay auction accounts are priced according to the number of positive “feedback” points that each victim account possesses (feedback is the core of eBay’s reputation system, whereby members evaluate their buying and selling experiences with other members). eBay accounts with fewer than 75 feedback history sell for $2 each, while those with higher levels of feedback command prices of $5 and higher apiece, because these accounts are more likely to be perceived as trustworthy by other eBay members.

    But don’t count on paying for any of these goods with a credit card; Badb.su accepts payment only through virtual currencies such as Liberty Reserve and WebMoney.

    Badb.su, like many other card shops, offers an a-la-carte, card-checking service that allows buyers to gauge the validity of stolen cards before or after purchasing them. Typically, these services will test stolen card numbers using a hijacked merchant account that initiates tiny charges or so-called pre-authorization checks against the card; if the charge or pre-auth clears, the card-checking service issues a “valid” response for the checked card number.

    Mr. Waledac: The Peter North of Spamming

    Microsoft on Monday named a Russian man as allegedly responsible for running the Kelihos botnet, a spam engine that infected an estimated 40,000 PCs. But closely held data seized from a huge spam affiliate program suggests that the driving force behind Kelihos is a different individual who commanded a much larger spam empire, and who is still coordinating spam campaigns for hire.

    Kelihos shares a great deal of code with the infamous Waledac botnet, a far more pervasive threat that infected hundreds of thousands of computers and pumped out tens of billions of junk emails promoting shady online pharmacies. Despite the broad base of shared code between the two malware families, Microsoft classifies them as fundamentally different threats. The company used novel legal techniques to seize control over and shutter both botnets, sucker punching Waledac in early 2010 and taking out Kelihos last fall.

    On Monday, Microsoft filed papers with a Virginia court stating that Kelihos was operated by Andrey N. Sabelnikov, a St. Petersburg man who once worked at Russian antivirus and security firm Agnitum. But according to the researcher who shared that intelligence with Microsoft — and confidentially with Krebs On Security weeks prior to Microsoft’s announcement — Sabelnikov is likely only a developer of Kelihos.

    “It’s the same code with modifications,” said Brett Stone-Gross, a security analyst who came into possession of the Kelihos source code last year and has studied the two malware families extensively.

    Rather, Stone-Gross said, the true coordinator of both Kelihos and Waledac is likely another Russian who is well known to anti-spam activists.

    WHO IS SEVERA?

    A variety of indicators suggest that the person behind Waledac and later Kelihos is a man named “Peter Severa” — known simply as “Severa” on underground forums. For several years running, Severa has featured in the Top 10 worst spammers list published by anti-spam activists at Spamhaus.org (he currently ranks at #5). Spamhaus alleged that Severa was the Russian partner of convicted U.S. pump-and-dump stock spammer Alan Ralsky, and indeed Peter Severa was indicted by the U.S. Justice Department in a related and ongoing spam investigation.

    It turns out that the connection between Waledac and Severa is supported by data leaked in 2010 after hackers broke into the servers of pharmacy spam affiliate program SpamIt. The data also include tantalizing clues about Severa’s real identity.

    In multiple instances, Severa gives his full name as “Peter North;” Peter Severa translates literally from Russian as “Peter of the North.” (The nickname may be a nod to the porn star Peter North, which would be fitting given that Peter North the spammer promoted shady pharmacies whose main seller was male enhancement drugs).

    Spamdot.biz moderator Severa listing prices to rent his Waledac spam botnet.

    According to SpamIt records, Severa brought in revenues of $438,000 and earned commissions of $145,000 spamming rogue online pharmacy sites over a 3-year period. He also was a moderator of Spamdot.biz (pictured at right), a vetted-members-only forum that included many of SpamIt’s top earners, as well as successful spammers/malware writers from other affiliate programs such as EvaPharmacy and Mailien.

    Severa seems to have made more money renting his botnet to other spammers. For $200, vetted users could hire his botnet to send 1 million pieces of spam; junk email campaigns touting employment/money mule scams cost $300 per million, and phishing emails could be blasted out through Severa’s botnet for the bargain price of $500 per million.

    Spamhaus says Severa’s real name may be Peter Levashov. The information Severa himself provided to SpamIt suggests that Spamhaus’s intelligence is not far off the mark.

    Severa had his SpamIt earnings deposited into an account at WebMoney, a virtual currency popular in Russia and Eastern Europe. According to a source that has the ability to look up identity information tied to WebMoney accounts, the account was established in 2001 by someone who entered a WebMoney office and presented the Russian passport #454345544. The passport bore the name of a then 26-year-old from Moscow — Viktor Sergeevich Ivashov.

    Flying the Fraudster Skies

    Given the heightened security surrounding air travel these days, it may be hard to believe that fraudsters would try to board a plane using stolen tickets. But incredibly, there are a number of criminal travel agencies doing business in the underground, and judging from the positive feedback left by patrons, business appears to be booming.

    Ad above says: Maldives Turkey Goa Bora-Bora, Carribes, Any country, any hotels and resorts of the world.

    The tickets often are purchased at the last minute and placed under the criminal buyer’s real name. The reservations are made using either stolen credit cards or hijacked accounts belonging to independent contractors in the travel industry.  Customers are charged a fraction of the cost of the tickets and/or reservations, typically between 25 and 35 percent of the actual cost.

    Criminal travel services are contributing to a recent spike in airline ticket fraud. In December, the Airlines Reporting Corporation, an industry clearinghouse, said it was seeing a marked increase in unauthorized tickets issued. Between August and November of last year, 113 incidents of fraudulently booked tickets were reported to ARC, up from just 18 such incidents reported in all of 2010. The aggregate face value of the unauthorized tickets in 2011 was more than $1 million. The ARC believes the increase in fraud is mainly due to an surge in phishing emails targeting travel agency employees and contractors.

    Some of the travel agencies in the criminal underground are full-service, pitching package deals that  include airfare, car rentals and even hotel stays. A hacker using the nickname “Yoshimo” on one prominent fraudster forum offers “80-95 percent working flight tickets in most countries (some restrictions apply),” for 25 percent of the original price, and 40 percent of the price for carded hotel stays and car rentals. He has been offering this service for more than two years, and has at least 275 positive reviews from current and former customers.

    Virtual Sweatshops Defeat Bot-or-Not Tests

    Jobs in the hi-tech sector can be hard to find, but employers in one corner of the industry are creating hundreds of full-time positions, offering workers on-the-job training and the freedom to work from home. The catch? Employees will likely toil for cybercrooks, and their weekly paychecks may barely cover the cost of a McDonald’s Happy Meal.

    Kolotibablo.com home page

    The abundance of these low-skilled, low-paying jobs is coming from firms that specialize in the shadowy market of mass-solving CAPTCHAs, those blurry and squiggly words that some websites force you to retype. One big player in this industry is KolotiBablo.com, a service that appeals to spammers and exploits low cost labor in China, India, Pakistan, and Vietnam.

    KolotiBablo, which means “earn money” in transliterated Russian, helps clients automate the solving of puzzles designed to prevent automated activity by bots, such as leaving spammy comments or mass-registering accounts at Webmail providers and social networking sites. The service offers an application programming interface (API) that allows clients to feed kolotibablo.com CAPTCHAs served in real time by various sites, which are then solved by KolotiBablo workers and fed back to the client’s system.

    Paying clients interface with the service at antigate.com, a site hosted on the same server as kolotibablo.com. Antigate charges clients 70 cents to $1 for each batch of 1,000 CAPTCHAs solved, with the price influenced heavily by volume. KolotiBablo says employees can expect to earn between $0.35 to $1 for every thousand CAPTCHAs they solve.

    The twin operations say they do not condone the use of their services to promote spam, or “all those related things that generate butthurt for the ‘big guys,’” mostly likely a reference to big free Webmail providers like Google and Microsoft. Still, both services can be found heavily advertised and recommended in several underground forums that cater to spammers and scam artists.

    Registered antigate.com users can read more about why customers typically purchase the service, and how KolotiBablo is run. From the description:

    “All CAPTCHAs in our service are completely solved by real humans, there are usually 500-1000 (and growing) workers online from all the world. That’s why we can process any CAPTCHAs at any volume for a fixed price $1 per 1000 CAPTCHAs.

    You may probably think that using human resource inappropriate or inhumane. However, keep in mind that we pay the most of collected money to our workers who sit in the poorest corners of our planet and this work gives them a stable ability to buy food, clothes for themselves and their families. Most of our staff is from China, India, Pakistan and Vietnam.”

    Pharma Wars: ‘Google,’ the Cutwail Botmaster

    Previous stories in my Pharma Wars series have identified top kingpins behind the some of the biggest spam botnets. Today’s post does that and more, including never-before-published information on “Google,” the lead hacker behind the world’s busiest spam botnet — Cutwail.

    December 2011 spam stats from M86Security

    For many years, Cutwail has been among the top three most prolific spam botnets. With the recent takedown of the Rustock botnet, Cutwail now is the top spam bot; according to M86 Security, versions of Cutwail are responsible for about 22 percent of the daily spam volumes worldwide.

    Security researchers have extensively dissected the technical machinery that powers Cutwail (a.k.a. “Pushdo” and “Pandex”), but until now little has been published about the brains behind it. Krebs On Security has learned that the individual principally responsible for developing and renting this crime machine to other miscreants was a top moneymaker for SpamIt, until recently the world’s largest rogue Internet pharmacy affiliate program.

    By the time he joined SpamIt in early 2007, the hacker named Google had already spent several years fine-tuning his spam botnet. Just months prior to its closure in Oct. 2010, SpamIt was hacked, and its customer and affiliate data leaked online. The data shows that Google used close to a dozen affiliate accounts at SpamIt, and made nearly $175,000 in commissions advertising SpamIt’s rogue online pharmacies with the help of Cutwail.

    But Google would make far more money renting his botnet to other spammers, and SpamIt affiliates quickly became his biggest client base. Interestingly, the proprietors of SpamIt initially asked for Google’s help not to spam rogue pharmacies, but to jump-start a new affiliate program called Warezcash to sell “OEM” software — mostly pirated copies of Microsoft Windows and other high-priced software titles.

    That relationship is evident from hundreds of chat logs between Google and SpamIt co-founder Dmitry “Saintd” Stupin. The conversations were part of thousands of hours of logs obtained by Russian cybercrime investigators who examined Stupin’s computer. The chats were later leaked online, and provide a rare glimpse into the day-to-day operations of Cutwail from the botmaster’s perspective. They also provide tantalizing clues as to the real-life identity of Google and his co-workers. Snippets of those conversations appear below, translated from their original Russian into English by native Russian speakers.

    THE CUTWAIL MACHINE

    Some of the best techical analysis of Cutwail came earlier this year in a paper from researchers at the University of California, Santa Barbara and Ruhr-University Bochum, which described in detail how the Cutwail botnet was operated, rented and promoted on the exclusive SpamIt forums. From their paper (PDF):

    “The Cutwail spam engine is known in spam forums by the name 0bulk Psyche Evolution, where it is rented to a community of spam affiliates. These affiliates pay a fee to Cutwail botmasters in order to use their botnet infrastructure. In return, the clients are provided with access to a Web interface (available in Russian or English language) that simplifies the process of creating and managing spam campaigns…”

    SpamIt affiliate records show that Google registered with the program using the email address psyche.evolution@gmail.com (according to historical WHOIS records, the domain name psyche-evolution.com was registered in 2005 by that same email address, to an organizations called “0bulk corp.” in Moscow).

    In several chats with Stupin, Google describes how he and his pals switched to pharmacy spamming when promoting stocks via spam became less lucrative. In a discussion on Feb. 25, 2007, Google said he was “renting software for spam,” to competing spam affiliate programs “Mailien,” “Bulker,” and “Aff Connection,” and that all of his clients had great success converting traffic into sales. “We have been spamming stocks, however now stocks started converting badly, so we decided to spam in parallel with some affiliate programs. We organized people, gave them tasks to do. We’ve been spamming them for a week only, but I think we’ll do good.”

    How Much Is Your Identity Worth?

    How much does it cost for thieves to discover the data that unlocks identity for creditors, such as your Social Security number, birthday, or mother’s maiden name? Would it surprise you to learn that crooks are selling this data to any and all comers for pennies on the dollar?

    superget.info home page

    At least, that’s the going price at superget.info. This fraudster-friendly site has been operating since July 2010, and markets the ability to look up SSNs, birthdays and other sensitive information on millions of Americans. Registration is free, and accounts are funded via WebMoney and Liberty Reserve, virtual currencies that are popular in the cybercriminal underground.

    Superget lets users search for specific individuals by name, city, and state. Each “credit” costs USD$1, and a successful hit on a Social Security number or date of birth costs 3 credits each. The more credits you buy, the cheaper the searches are per credit: Six credits cost $4.99; 35 credits cost $20.99, and $100.99 buys you 230 credits. Customers with special needs can avail themselves of the “reseller plan,” which promises 1,500 credits for $500.99, and 3,500 credits for $1000.99.

    “Our Databases are updated EVERY DAY,” the site’s owner enthuses. “About 99% nearly 100% US people could be found, more than any sites on the internet now.”

    Customers who aren’t choosy about the identities they’re stealing can get a real bargain. Among the most trafficked commodities in the hacker underground are packages called “fullz infos,” which include the full identity information on dozens or hundreds of individuals.

    The table at the right shows the bulk lookup price-per-identity in this class. In the “Fullz Info USA Type A” package, each record includes the subject’s first name, last name, middle name, email address, email password, physical address, phone number, date of birth, Social Security number, drivers license number, bank name, bank account number, bank routing number, the victim employer’s name, and the number of years that individual has been at his or her current job. The proprietor of this shop says he has more than 330,000 records of this type, and is adding 300-400 new records each day.

    If you want the mother’s maiden name included in each of the bulk records, you’ll need to select “Fullz Info USA Type B”; the site’s owner says this package includes data from an older database, and perhaps that explains why the prices for these identities (pictured at left) are so much lower than those in the Type A category. The price in Type B starts at 16 cents per identity, and falls as low as nine cents per record for those requesting more than 20,000 fullz from this category.

    ATM Skimmer Powered by MP3 Player

    Almost a year ago, I wrote about ATM skimmers made of parts from old MP3 players. Since then, I’ve noticed quite a few more ads for these MP3-powered skimmers in the criminal underground, perhaps because audio skimmers allow fraudsters to sell lucrative service contracts along with their theft devices.

    Using audio to capture credit and debit card data is not a new technique, but it is becoming vogue: Square, an increasingly popular credit card reader built for the iPhone, works by plugging into the headphone jack on the iPhone and converting credit card data stored on the card into audio files.

    An audio skimmer for a Diebold ATM.

    The device pictured here is a card skimmer designed to fit over the card acceptance slot on a Diebold Opteva 760, one of the most common ATMs around. The green circuit board on the left was taken from an MP3 player (no idea which make or model). When a card is slid past the magnetic reader (the small black rectangle at the end of the black and red wires near the center of the picture), the MP3 player “hears” the data stored on the card’s magnetic stripe, and records it as an audio file to a tiny embedded flash memory device.

    Financial Mogul Linked to DDoS Attacks

    Pavel Vrublevsky, the embattled co-founder of ChronoPay — Russia’s largest online payments processor — has reportedly fled the country after the arrest of a suspect who confessed that he was hired by Vrublevsky to launch a debilitating cyber attack against a top ChronoPay competitor.

    KrebsOnSecurity has featured many stories on Vrublevsky’s role as co-founder of the infamous rogue online pharmacy Rx-Promotion, and on his efforts to situate ChronoPay as a major processor for purveyors of “scareware,” software that uses misleading computer virus infection alerts to frighten users into paying for worthless security software.  But these activities have largely gone overlooked by Russian law enforcement officials, possibly because the consequences have not impacted Russian citizens.

    In the summer of 2010, rumors began flying in the Russian blogosphere that Vrublevsky had hired a hacker to launch a distributed denial of service (DDoS) attack against Assist, the company that was processing payments for Aeroflot, Russia’s largest airline. Aeroflot had opened its contract for processing payments to competitive bidding, and ChronoPay was competing against Assist and several other processors. The attack on Assist occurred just weeks before Aeroflot was to decide which company would win the contract; it so greatly affected Assist’s operations that the company was unable to process payments for extended periods of time. Citing the downtime in processing as a factor in its decision, Aeroflot ultimately awarded the contract to neither ChronoPay nor Assist, but instead to Alfa-Bank, the largest private bank in Russia.

    According to documents leaked to several Russian security blogs, investigators with the Russian Federal Security Service (FSB) this month arrested a St. Petersburg man named Igor Artimovich in connection with the attacks. The documents indicate that Artimovich — known in hacker circles by the handle “Engel” — confessed to having used his botnet to attack Assist after receiving instructions and payment from Vrublevsky. The same blogs say Vrublevsky has fled the country. Sources close to the investigation say he is currently in the Maldives. Vrublevsky did not respond to multiple requests for comment.

    "Topol Mailer" botnet interface allegedly used by Artimovich.

    The allegations against Artimovich and Vrublevsky were supported by evidence collected by Russian computer forensics firm Group-IB, which said it assisted the FSB with the investigation. Group-IB presented detailed information on the malware and control servers used to control more than 10,000 infected PCs, and shared with investigators screen shots of the botnet control panel (pictured at left) allegedly used to coordinate the DDoS attack against Assist. Group-IB said Artimovich’s botnet also was used to attack several rogue pharmacy programs that were competing with Rx-Promotion, including Glavmed and Spamit (these attacks also were observed by security firm SecureWorks in February).

    This DDoS saga is the latest chapter in a fascinating drama playing out between the two largest rogue Internet pharmacies: Vrublevsky’s Rx-Promotion and Glavmed (a.k.a. “Spamit”), a huge pharma affiliate program run by Igor Gusev, the man who co-founded ChronoPay with Vrublevsky in 2003.

    Rustock Botnet Suspect Sought Job at Google

    Microsoft has fingered  a possible author of the late Rustock spam botnet – a self-described software engineer and mathematician who aspired to one day be hired by Google. Microsoft has apparently allocated significant resources to finding the author, but has not been able to locate him.

    Rustock remains dead, but Microsoft is still on the hunt for the Rustock author. In its Second Status Report (PDF) filed last week with a district court in Seattle, Microsoft said it inquired with virtual currency provider Webmoney about the owner of an account used to rent Rustock control servers,  and confirmed that the account was affiliated with a man named Vladimir Alexandrovich Shergin. Microsoft also mentioned another suspect, “Cosma2k,” possibly named Dmitri A. Sergeev, Artem Sergeev, or Sergey Vladomirovich Sergeev. Microsoft said it is continuing its investigation of these names, to determine whether additional contact information can be identified and to which notice and service can be effected.

    To help in the hunt, I hereby offer some details about him.

    Microsoft helped to dismantle Rustock in March after a coordinated and well-timed “stun” targeting the spam botnet’s infrastructure, which was mainly comprised of servers based in U.S. hosting facilities. Two weeks after that takedown, I tracked down a Web hosting reseller in Eastern Europe who acknowledged renting some of those servers to the apparent Rustock author. That reseller shared the Webmoney account number used to purchase access to the servers, and Russian investigators I spoke with confirmed that the account had been registered by a Russian named Vladimir Shergin. By consulting a leaked database I obtained last year of the top earners for Spamit.com — at the time the world’s largest rogue online pharmacy network — I discovered that the same Webmoney account was shared by three of the top ten Spamit affiliates.

    The information from the reseller and from the Spamit database traced back to a Spamit affiliate who used the pseudonym “Cosma2k.” The email address tied to that Cosma2K account was “ger-mes@ger-mes.ru”. When I came into possession of the Spamit.com data back in August 2010, the site ger-mes.ru was still responding to requests, and the homepage presented some very interesting information. It included a job résumé, underneath a picture of a young man holding a mug. Above the image was the name “Sergeev, Dmitri A.” At the very top of the page was a simple message: “I want to work in Google.” Beneath the résumé is the author’s email address, followed by the message, “Waiting for your job”!

    Here is the complete page and résumé, in case anyone wants a closer look at this Belorussian-educated job seeker. I shared the information with Google in August 2010, to find out if they’d received a job application from this person, or if they’d considered flying him to Mountain View, Calif. for an interview. I still don’t have an answer to either question. I shared this same information with Microsoft in March.

    Microsoft seems determined to bring the Rustock malefactors to court. Maybe the mug shot in this résumé will help to identify at least one of them.

    Microsoft Hunting Rustock Controllers

    Who controlled the Rustock botnet? The question remains unanswered: Microsoft’s recent takedown of the world’s largest spam engine offered tantalizing new clues to the identity and earnings of the Rustock botmasters. The data shows that Rustock’s curators made millions by pimping rogue Internet pharmacies, but also highlights the challenges that investigators still face in tracking down those responsible for building and profiting from this complex crime machine.

    Earlier this month, Microsoft crippled Rustock by convincing a court to let it seize dozens of Rustock control servers that were scattered among several U.S.-based hosting providers. Shortly after that takedown, I began following the money trail to learn who ultimately paid the botnet controllers’ hosts for their services.

    According to interviews with investigators involved in the Rustock takedown, approximately one-third of the control servers were rented from U.S. hosting providers by one entity: A small business in Eastern Europe that specializes in reselling hosting services to shadowy individuals who frequent underground hacker forums.

    KrebsOnSecurity.com spoke to that reseller. In exchange for the agreement that I not name his operation or his location, he provided payment information about the customer who purchased dozens of servers that were used to manipulate the day-to-day operations of the massive botnet.

    The reseller was willing to share information about his client because the customer turned out to be a deadbeat: The customer walked out on two months worth of rent, an outstanding debt of $1,600. The reseller also seemed willing to talk to me because I might be able bend the ear of Spamhaus.org, the anti-spam group that urged ISPs worldwide to block his Internet addresses (several thousand dollars worth of rented servers) shortly after Microsoft announced the Rustock takedown.

    I found the reseller advertising his services on a Russian-language forum that caters exclusively to spammers, where he describes the hardware, software and connection speed capabilities of the very servers that he would later rent out to the Rustock botmaster. That solicitation, which was posted on a major spammer forum in January 2010, offered prospective clients flexible terms without setting too many boundaries on what they could do with the servers. A translated version of part of his message:

    “I am repeating again that the servers are legitimate, funded by us and belong to our company. To the datacenters, we are responsible to ensure that you are our client, and that you will not break the terms of use. Also, to you we are responsible to make sure that the servers are not going to be closed down because of credit card chargebacks, as it happens with servers funded with stolen credit cards. In conclusion, they do not have an abuse report center, they are suitable for legitimate projects, VPNs and everything else that does not lead to problems and complaints to the data center from active Internet users. Please, take it in consideration, so that nobody is pissed off and there is no bad impression from our partnership.”

    The reseller said he had no idea that his customer was using the servers to control the Rustock botnet, but he hastened to add that this particular client didn’t attract too much attention to himself. According to the reseller, the servers he resold to the Rustock botmaster generated just two abuse complaints from the Internet service providers (ISPs) that hosted those servers. Experts say this makes sense because botnet control servers typically generate few abuse complaints, because they are almost never used for the sort of activity that usually prompts abuse reports, such as sending spam or attacking others online. Instead, the servers only were used to coordinate the activities of hundreds of thousands of PCs infected with Rustock, periodically sending them program updates and new spamming instructions.

    The reseller was paid for the servers from an account at WebMoney, a virtual currency similar to PayPal but more popular among Russian and Eastern European consumers. The reseller shared the unique numeric ID attached to that WebMoney account — WebMoney purse “Z166284889296.” That purse belonged to an “attested” WebMoney account, meaning that the account holder at some point had to verify his identity by presenting an official Russian passport at a WebMoney office. A former law enforcement officer involved in the Rustock investigation said the name attached to that attested account was “Vladimir Shergin.” According to the reseller, the client stated in an online chat that he was from Saint Petersburg, Russia.
