Drinkman and Smilianets Sentenced: The End to Our Longest Databreach Saga?

On Thursday, February 15, 2018, we may have finally reached the end of the Albert Gonzalez Databreach Saga.  Vladimir Drinkman, age 37, was sentenced to 144 months in prison, after pleading guilty before U.S. District Judge Jerome Simandle in New Jersey.  His colleague, Dmitriy Smilianets, age 34, had also pleased guilty and was sentenced to 51 months and 21 days in prison (which is basically "time served", so he'll walk immediately).  The pair were actually arrested in the Netherlands on June 28, 2012, and the guilty pleas had happened in September 2015th after they were extradited to New Jersey.

Those who follow data breaches will certainly be familiar with Albert Gonzalez, but may not realize how far back his criminal career goes.

On July 24, 2003, the NYPD arrested Gonzalez in front of a Chase Bank ATM at 2219 Broadway found Gonzalez in possession of 15 counterfeit Chase ATM cards and $3,000 in cash. (See case 1:09-cr-00626-JBS).  After that arrest, Gonzalez was taken under the wing of a pair of Secret Service agents, David Esposito and Steve Ward.  Gonzalez describes some of the activities he engaged in during his time as a CI in his 53 page appeal that he files March 24, 2011 from his prison cell in Milan, Michigan.

At one point, he claims that he explained to Agent Ward that he owed a Russian criminal $5,000 and he couldn't afford to pay it.  According to his appeal, he claims Ward told him to "Go do your thing, just don't get caught" and that Agent Ward later asked him if he had "handled it." Because of this, Gonzalez (who again, according to his own sentencing memo, likely has Asperger's) claims he believed that he had permission to hack, as long as he didn't get caught.

Over Christmas 2007, Gonzalez and his crew hacked Heartland Payments Systems and stole around 130 million credit and debit cards.  He was also charged with hacking 7-Eleven (August 2007), Hannaford Brothers (November 2007) where he stole 4.2 million credit and debit cards. Two additional data breaches against "Company A" and "Company B" were also listed as victims.  In Gonzalez's indictment, it refers to "HACKER 1 who resided in or near Russia" and "HACKER 2 who resided in or near Russia."  Another co-conspirator "PT" was later identified as Patrick Toey, a resident of Virginia Beach, VA.  (Patrick Toey's sentencing memorandum is a fascinating document that describes his first "Cash out trip" working for Albert Gonzalez in 2003. Toey describes being a high school drop out who smoked marijuana and drank heavily who was "put on a bus to New York" by his mother to do the cash out run because she needed rent money.  Toey later moved in with Gonzalez in Miami, where he describes hacking Forever 21 "for Gonzalez" among other hacks.

Gonzalez's extracurricular activities caught up with him when Maksym Yastremskiy (AKA Maksik) was arrested in Turkey.  Another point of Gonzalez's appeal was to say that Maksik was tortured by Turkish police, and that without said torture, he never would have confessed, which would have meant that Gonzalez (then acting online as "Segvec") would never have been identified or arrested.  Gonzalez claims that he suffered from an inadequate defense, because his lawyer should have objected to the evidence "obtained under torture."  These charges against Gonzalez were tried in the Eastern District of New York (2:08-cr-00160-SJF-AKT) and proved that Gonzalez was part of the Dave & Buster's data breach

On December 15, 2009, Gonzalez tried to shrug off some of his federal charges by filing a sentencing memo claiming that he lacked the "capacity to knowingly evaluate the wrongfulness of his actions" and asserting that his criminal behavior "was consistent with description of the Asperger's discorder" and that he exhibited characteristics of "Internet addiction."  Two weeks later, after fighting that the court could not conduct their own psychological exam, Gonzalez signed a guilty plea, agreeing that the prosecutor would try to limit his sentence to 17 years. He is currently imprisoned in Yazoo, Mississippi (FBOP # 25702-050) scheduled to be released October 29, 2025.

Eventually "HACKER 1" and "HACKER 2" were indicted themselves in April 2012, with an arrest warrant issued in July 2012, but due to criminals still at large, the indictment was not unsealed until December 18, 2013. HACKER 1 was Drinkman.  HACKER 2 was Alexandr Kalinin, who was also indicted with Drinkman and Smilianets.

Shortly after the Target Data Breach, I created a presentation called "Target Data Breach: Lessons Learned" which drew heavily on the history of Drinkman and Smilianets. Some of their documented data breaches included:
VictimDateDamages
NASDAQMay 2007  loss of control
7-ELEVEN August 2007
Carrefour October 2007 2 million cards
JCPenneyOctober 2007
HannafordNovember 2007 4.2 million cards

Visa JordanFeb-Mar '11  800,000 cards
Global Payments SystemsJan '11 to Mar '12
Diners Club SingaporeJun '11
IngenicardMar '12 to Dec '12

During the time of these attacks, Dimitry Smilianets was also leading the video game world.  His team, The Moscow 5, were the "Intel Extreme Masters" champions in the first League of Legends championship, also placing in the CounterStrike category.   Smilianets turned out not to be the hacker, but rather specialized in selling the credit cards that the other team members stole.  Steal a few hundred million credit cards and you can buy a nice gaming rig!

 How did these databreaches work?


Lockheed Martin's famous paper "Intelligence-Driven Computer Network Defense Informed by Analysis of Adversary Campaigns and Intrusion Kill Chains" laid out the phases of an attack like this:

But my friend Daniel Clemens had explained these same phases to me when he was teaching me the basics of Penetration Testing years before when he was first starting Packet Ninjas!

1. External Recon - Gonzalez and his crew scan for Internet-facing SQL servers
2. Attack (Dan calls this "Establishing a Foothold") - using common SQL configuration weaknesses, they caused a set of additional tools to be downloaded from the Internet
3. Internal Recon - these tools included a Password Dumper, Password Cracker, Port Scanner,  and tools for bulk exporting data
4. Expand (Dan calls this "Creating a Stronghold")  - usually this consisted with monitoring the network until they found a Domain Admin userid and password.  (for example, in the Heartland Payments attack, the VERITAS userid was found to have the password "BACKUP" which unlocked every server on the network!
5. Dominate - Gonzalez' crew would then schedule an SQL script to run a nightly dump their card data
6. Exfiltrate - data sent to remote servers via an outbound FTP.

In Rolling Stone, Gonzalez claims he compromised more than 250 networks
In the Rolling Stone article, "Sex, Drugs, and the Biggest Cybercrime of All Time" , Steven Watt, who was charged in Massachusetts for providing attack tools to Gonzalez in October 2008.  Watt's tools were used in breaches, including BJ's Wholesale Club, Boston Market, Barnes & Noble, Sports Authority, Forever 21, DSW, and OfficeMax.  As part of his sentencing, Watt was ordered to repay $171.5 Million dollars.

Almost all of those databreaches followed the same model ... scan, SQL Inject, download tools, plant a foothold, convert it to a stronghold by becoming a domain admin, dominate the network, and exfiltrate the data. 

How did the TARGET Data breach happen, by the way?  Target is still listed as being "Unsolved" ...   but let's review.  An SQL injection led to downloaded tools, (including NetCat, PSExec, QuarksPWDump, ElcomSoft's Proactive Password Auditor, SomarSoft's DumpSec, Angry IP Scanner (for finding database servers), and Microsoft's OSQL and BCP (Bulk Copy)), a Domain Admin password was found (in Target's case, a BMC server monitoring tool running the default password), the POS Malware was installed, and data exfiltration begun. 

Sound familiar???

Justice?

With most of Gonzalez's crew in prison by 2010, the data breaches kept right on coming, thanks to Drinkman and Smilianets. 

Drinkman, the hacker, was sentenced to 144 months in prison.
Smilianets, the card broker, was sentenced to 51 months and 21 days, which was basically "time served" -- he was extradited to the US on September 7, 2012, so he'll basically walk.

Will Smilianets return to video gaming? to money laundering? or perhaps choose to go straight?

Meanwhile, Alexandr Kalinin, of St. Petersburg, Russia; Mikhail Rytikov, of Odessa, Ukraine; and Roman Kotov, of Moscow, Russia, are all still at large.  Have they learned from the fate of their co-conspirators? or are they in all likelihood, scanning networks for SQL servers, injecting them, dropping tools, planting footholds, creating strongholds, and exfiltrating credit card data from American companies every day?

Kalinin (AKA Grig, AKA "g", AKA "tempo") is wanted for hacking NASDAQ and planting malware that ran on the NASDAQ networks from 2008 to 2010.  (See the indictment in the Southern District of New York, filed 24JUL2013 ==> 1:13-cr-00548-ALC )

Mykhailo Sergiyovych Rytikov is wanted in the Western District of Pennsylvania for his role in a major Zeus malware case.  Rytikov leased servers to other malware operators.  Rytikov is also indicted in the Eastern District of Virginia along with Andriy DERKACH for running a "Dumps Checking Service" that processed at least 1.8 million credit cards in the first half of 2009 and that directly led to more than $12M in fraud.  ( 1:12-cr-00522-AJT filed 08AUG2013.)  Rytikov did have a New York attorney presenting a defense in the case -- Arkady Bukh argues that while Rytikov is definitely involved in web-hosting, he isn't responsible for what happens on the websites he hosts.

Roman Kotov, and Rytikov and Kalinin, are still wanted in New Jersey as part of the case 1:09-cr-00626-JBS (Chief Judge Jerome B. Simandle ). This is the same case Drinkman and Smilianets were just sentenced under.

20 Million Chinese Hotel Guests have data leaked

This morning Secure Computing shared a brief article about Data on 20 Million Chinese Hotel Guests being shared by hackers. Unfortunately the only link in the article was a search for the word Breach on SCMagazine's own website.

The source was South China Morning Post, which has actually been writing about this for some time. On October 11, Amy Li reported that "Home Inn Hotels" a popular discount chain, and Hanting Hotel Group, were using "faulty hotel management software" developed by CNWISDOM. This was reported by "independent internet security watchdog Wuyun.org". The NASDAQ traded hotel chain eventually acknowledged the vulnerability, which they described as a weakness in their Wireless Portal Security System, and announced on their home page that the issue had been resolved, thanking WooYun for helping them with the vulnerability.

CNWisdom Data Leaks

Shortly after the initial exchange, a seller on Taobao (think Chinese eBay) announced that he was selling 8 Gigabytes of hotel guest data for 2,000 Yuan. South China Morning Post reported that the chain had 450,000 hotel rooms in 4,500 hotels, and that when guests register, they are required to provide their home address, phone number, ID card, date of birth, and workplace if they want to use the WiFi service. This is apparently the data that was received.

As reported in Patrick Boehler December 9th story in the South China Morning Post, Chinese Hackers Leak Hotel Guest Data on WeChat, multiple websites were distributing the hotel data for 20 million guests, and some enterprising hackers had even built a chat interface allowing you to TXT someone's ID card number to the service and having it reply with the details of any hotel stays by that guest.

WooYun

WooYun regularly shares vulnerability data, so we thought we would start at the beginning and find that. There were several "cnwisdom" breach reports there, including:

WooYun-2013-41171 (submitted October 28, 2013) - which referred to an SQL injection vulnerability

WooYun-2013-41171 (submitted October 27, 2013) - which referred to a STRUCTS problem

WooYun-2013-034935 (submitted August 21, 2013) - the WiFi Data Leak

Unfortunately, I have to rely on some Google Translate here ...

The way WooYun explains it is (Gary's paraphrase of the Google Translate of what they said:)

"Users connect to their hotel's open WiFi, which requires them to use a webpage to authenticate. That webpage is using http protocol, which means the username and password are transmitted in the clear. But the next phase of the authentication is to update a central database of WiFi information. IN THE CLEAR, the authentication connects to a database using the username "cnwisdomapi" and the password "3b823[马赛克]ac36a"!!
That authentication userid and password can be used to query details for anyone who used the WIFI in ANY of these hotels!

After the media used this screen shot in their reports, the Hotel chain responding saying that the screen shot did not represent personal information of their guests.

The "Vulnerability Response" section says that the vendor was notified and confirmed the vulnerability on August 26th. On October 8th, they replied that the Vulnerabilities had been repaired and a proper authentication method that preserved encryption throughout the process to protect guests had been implemented.

WooYun and 189

This is hardly the first major breach from WooYun! In January they reported serious vulnerabilities in the Chinese telecom giant 189's infrastructure that allowed any user with a webbrowser to get detailed billing information, including the user name, address, and detailed call history for any mobile phone user!

The same breach reported also shared details on how any one could access a webserver on "wapsc.189.cn:8006" and use the "wapLogin/sendSms.action" to send unauthenticated SMS messages to any cell phone!

In a wonderful example of responsible reporting, WooYun declared the vulnerability to be "Level 20" (their highest rank) and reported the details to the CNCERT National Internet Emergency Center on January 22 prior to releasing the details publicly on March 8, 2013.

TJX: From Florida to the Ukraine?

Last week the media lit up with speculations that 24 year old Ukrainian hacker, Maksym Yastremskiy, who had been arrested in Turkey on August 2nd, may be behind the TJX Credit Card hack. The Boston Globe's Ross Kerber may have had the best coverage with his story "Suspect
named in TJX credit card probe"
on August 21. The story quoted Greg Crabb of the US Postal Inspection Service's global investigations division. Crabb said Maksym was "likely the largest seller of stolen TJX numbers". TJX, the financial company in the TJ Maxx conglomerate, believes that as many as 45.7 million credit cards were stolen during a breach during 2005 and 2006, which captured credit card transactions all the way back to 2003.

How's your Turkish? This August 2nd article , "Antalya'da yakalanan Ukraynalı hacker 80 bin kişiyi dolandırmış", interviews Turkish police officer, Feyzullah Arslan, who arrested Maksym after a sting in a luxury night club in Kerem, Turkey.



Using a "follow-the-money" investigative technique, the investigation began with 10 guilty pleas in Florida back in March from a crew of careless cyber criminals who had racked up millions of dollars of purchases from Wal-Mart and other Florida retailers using stolen credit cards that tracked back to TJX. The Florida investigation actually started when Gainesville police were contacted regarding two local Wal-Mart stores who had made individual gift-card sales in the amounts of $18,000 and $24,000. HINT: IF SOMEONE WANTS $24,000 IN WAL-MART GIFT CARD, THERE MAY BE A CRIME LYING ABOUT.

Those cards were used at a Sam's Club in Miami, along with many other cards, to buy large quantities of electronics and jewelry. At that time, the cards were all tracked back to TJX, and an estimate of the loss from the database hack was released in the news -- Gainesville police Sergeant Ray Barber revealed "They estimate the loss from that hack job to be around $8 million", although this particular crew had only rung up $1 million in charges so far. (See, for example: "Florida police make arrests in TJX, Winners credit card theft".

The first six, arrested March 19, were:

Irving Jose Escobar, 18
Reinier Camaraza Alvarez, 27
Julio Oscar Alberti, 33
Dianelly Hernandez, 19
Nair Zuleima Alvarez, 40
Zenia Mercedes Llorente

All ten, including the additional:

Erick Fernandez Rodriguez
Hector Alfaro Rodriguez
Alexis Arcia
Armando Ochoa

have Mugshots posted on eweek.com.




In a USA Today story a map of Irving Escobar's shopping spree, where he bought as many as 60 $400 gift cards in a single location, and then spent the money from November 1st to January 18th, is mapped out.



The big break in this first case came when an alert Wal-Mart employee followed the gift card purchases out of the store and recorded their license plate number. (For more, see the March 24, 2007 Boston Globe story by Ross Kerber, quoted here: Scam May Be Tied to Stolen TJX Data

A second Florida-based TJX gang plead guilty in late June. This group was charged with possessing 172,000 sets of credit card data, which had been used to make at least $75 Million in bogus credit card charges. Arrested in this scam were:

Miguel Alegria, 46, of Hialeah, FL
Raynier Pupo, 22, of Miami, FL
Ariel Montero, 32, of Aventura, FL
Javier Padron-Bravo, 35, of Aventura, FL
Julio Lopez, 30, of Hialeah, FL
and Anett VIllar, 26, of Hialeah, FL



Alegria, Pupo, Montero, and Padron-Bravo plead guilty to conspiracy in exchange for a plea agreement that included cooperation.

The Nashville Secret Service ran the investigation as "Operation Blinky" named for the first suspect's online name, which they co-opted as an undercover identity. For more see: TJX, Polo Data Surfaces In Another Credit Card Bust.
