Pharma Wars: Mr. Srizbi vs. Mr. Cutwail

The previous post in this series introduced the world to “Google,” an alias chosen by the hacker in charge of the Cutwail spam botnet. Google rented his crime machine to members of SpamIt, an organization that paid spammers to promote rogue Internet pharmacy sites. This made Google a top dog, but also a primary target of rival botmasters selling software to SpamIt, particularly the hacker known as “SPM,” the brains behind the infamous Srizbi botnet.

Today’s Pharma Wars entry highlights that turf battle, and features newly discovered clues about the possible identity of the Srizbi botmaster, including his whereabouts and current occupation.

Reactor Mailer Terms of Service, 2005

Srizbi burst onto the malware scene in early 2007, infecting hundreds of thousands of Microsoft Windows computers via exploit kits stitched into hacked and malicious Web sites. SpamIt members could rent access to the collection of hacked machines via a piece of spamware that had been around since 2004, known as “Reactor Mailer.”

This page from archive.org (pictured at right) is a Feb. 2005 snapshot of the terms of service for the Reactor Mailer service, explaining how it worked and its pricing structure. The document is signed by  “SPM,” who claims to be the CEO of a company called Elphisoft. He asks customers and would-be clients to contact him via ICQ instant message ID 360000 (the importance of this number will be apparent later in the story).

That same ICQ number features prominently in dozens of chat logs that apparently belonged to SpamIt co-administrator Dmitry “Saintd” Stupin. The logs were leaked online last year after Russian investigators questioned Stupin as part of an investigation into Igor Gusev, the alleged other co-founder of SpamIt. Facing criminal charges for his alleged part in SpamIt, Gusev chose to shutter the program October 2010, but not before its affiliate database was stolen and also leaked online.

BOTMASTER BATTLE

SPM is introduced to SpamIt in May 2007, when he joins the program with the hopes of becoming the default spam software provider for the pharmacy affiliate program. The chats translated and recorded at this link show SPM’s early communications with SpamIt, in which he brings on board several other affiliates who will help develop and maintain his Reactor/Srizbi botnet.

Very soon after joining SpamIt, SPM identifies Google — the Cutwail botmaster — as his main competitor, and sets off to undermine Google and to become the default spam software provider to SpamIt.

The following is from a chat between SPM and Stupin, recorded Oct. 9, 2007, in which SPM argues that he should be the primary spam software seller for SpamIt, and that his software’s logo should be embedded in the SpamIt banner at the organization’s closely-guarded online user forum.

Chats With Accused ‘Mega-D’ Botnet Owner?

Recently leaked online chat records may provide the closest look yet at a Russian man awaiting trial in Wisconsin on charges of running a cybercrime machine once responsible for sending between 30 to 40 percent of the world’s junk email.

Oleg Nikolaenko

Oleg Y. Nikolaenko, a 24-year-old who’s been dubbed “The King of Spam,” was arrested by authorities in November 2010 as he visited a car show in Las Vegas. The U.S. Justice Department alleges that Nikolaenko, using the online nickname “Docent” earned hundreds of thousands of dollars using his “Mega-D” botnet, which authorities say infected more than half a million PCs and could send over 10 billion spam messages a day. Nikoalenko has pleaded not guilty to the charges, and is slated to appear in court this week for a status conference (PDF) on his case.

The Justice Department alleges that Nikolaenko spammed on behalf of Lance Atkinson and other members of Affking, an affiliate program that marketed fly-by-night online pharmacies and knockoff designer goods. Atkinson told prosecutors that one of his two largest Russian spamming affiliates used the online moniker Docent. He also said that Docent received payment via an ePassporte account under the name “Genbucks_dcent.” FBI agents later learned that the account was registered in Nikolaenko’s name and address in Russia, and that the email address attached to the account was 4docent@gmail.com.

According to my research, Docent also spammed for other rogue pharmacy programs. In fact, it’s hard to find one that didn’t pay him to send spam. In my Pharma Wars series, I’ve detailed how Russian cybercrime investigators probing the operations of the massive GlavMed/SpamIt rogue pharmacy operation seized thousands of chat logs from one of its principal organizers. The chats were later leaked online and to select journalists. Within those records are hundreds of hours of chats between the owners of the pharmacy program and many of the world’s biggest spammers, including dozens with one of its top earners — Docent.

According to the SpamIt records, Docent earned commissions totaling more than $325,000 promoting SpamIt pharmacy sites through spam between 2007 and 2010. The Docent in the SpamIt database also had his earnings sent to the same ePassporte account identified by the FBI. The Docent in the leaked chats never references himself as Nikolaenko, but in several cases he asks SpamIt coordinators to send documents to him at the 4docent@gmail.com address.

The chats between Docent and Stupin show a young man who is ultra-confident in the value and sheer spam-blasting power of his botnet. Below are the first in a series of conversation snippets between Docent and SpamIt co-administrator Dmitry Stupin. Before each is a brief note providing some context.

In the transcript that follows, Stupin tries to woo Docent to join SpamIt. Docent negotiates a much higher commission rate than is usually given to new spamming partners. The typical rate is 30 percent of each sale, but Docent is a known figure in the spamming underground, and argues that his botnet will bring such massive traffic to the SpamIt pharmacies that he deserves a higher 45 or 50 percent cut of the sales. This conversation was recorded on Feb. 1, 2007.

Stupin:  Hello! You have communicated with ICQ 397061228, I am writing regarding your case, Docent.

Docent: Which case?

Stupin:  Do you want to send spam regarding our partnerka [“partnerka” is Russian slang for a mix of private and semi-public affiliate groups that form to facilitate cybercrime activities].

Docent: Which exactly do you mean? I have not yet communicated with this 397061228.

Stupin: Here is the letter which recently came from  you: “It is usual spam,  GI bases, not opt-in. Big volume of emails. I mail a lot of [competing pharmacy] programs, Bulker, Mailien, SRX. I’m a member of most bulk forums. So if you need references, i can provide them. Usual traffic is 2k+ uniques. Also i need bulk-host.”

Docent: Yes, I got it. It’s just nobody IM’d me.

Stupin: ок) What kind of volumes of spam can you deliver? We are soon deploying our own “partnerka” for spam, we just do not have it right now.

Docent: Volumes are huge, 500 million + / day.

Stupin: Wow! Are you not accidentally on [Spamhaus] ROKSO List ?

Docent: Yes, it’s a list of idiots :), with the exception of a couple of people.

Stupin:  We do contract people for our spam campaigns, but only verified people. We are not publicly opened yet.

Flashy Cars Got Spam Kingpin Mugged

A Russian spammer suspected of maintaining the infamous Rustock spam botnet earned millions of dollars blasting junk email for counterfeit Internet pharmacies. Those ill-gotten riches let him buy flashy sports cars, but new information suggests that this attracted the attention of common street thugs who targeted and ultimately mugged the spammer, stealing two of his prized rides.

BMW 530xi

In March, I published a story linking the Rustock botnet to a spammer who used the nickname Cosma2k. This individual was consistently one of the top five moneymakers for SpamIt, which, until its closure last fall, paid spammers millions of dollars a year and was the world’s largest distributor of junk mail.

Earlier this month, someone leaked thousands of online chat logs taken from Dmitry “SaintD” Stupin, a Russian who allegedly ran the day-to-day operations of SpamIt. Those records include numerous chat conversations allegedly between Stupin and a SpamIt affiliate named Cosma.

In several chats, Cosma muses on what he should do with tens of thousands of compromised but otherwise idle PCs under his control. Throughout the discussions between Stupin and Cosma, it is clear Cosma had access to internal SpamIt resources that other spammers did not, and that he had at least some say in the direction of the business.

In one conversation, dated Oct. 14, 2008, Cosma allegedly tells Stupin that he’s dialed back his public image a few notches, after attracting unwanted attention from other crooks. The conversation below, translated from Russian into English, begins with a request from Cosma to withdraw funds from a SpamIt operating account.

Cosma: Hey. May I withdraw some money from the account?

Stupin: Surely you may.

Stupin: Sorry, I was picking up my car from the service shop.

Cosma: What got broken?

Stupin: Someone threw a stone, when the car was parked near home.

Cosma: Damn. What kind of car?

Stupin: Volvo.

Cosma: Fond of safety?

Stupin: Yes, and I am at ease when I am driving it. It’s a huge difference after Honda :)

Cosma: I also had enough of expensive rigs. =) They are getting stolen all the time and everyone is looking at you, estimating the score, and then rob you =) I have had such experience =)
