Drugs Tripped Up Suspects In First Known ATM “Jackpotting” Attacks in the US

On Jan. 27, 2018, KrebsOnSecurity published what this author thought was a scoop about the first known incidence of U.S. ATMs being hit with “jackpotting” attacks, a crime in which thieves deploy malware that forces cash machines to spit out money like a loose Las Vegas slot machine. As it happens, the first known jackpotting attacks in the United States were reported in November 2017 by local media on the west coast, although the reporters in those cases seem to have completely buried the lede.

Isaac Rafael Jorge Romero, Jose Alejandro Osorio Echegaray, and Elio Moren Gozalez have been charged with carrying out ATM “jackpotting” attacks that force ATMs to spit out cash like a Las Vegas casino.

On Nov. 20, 2017, Oil City News — a community publication in Wyoming — reported on the arrest of three Venezuelan nationals who were busted on charges of marijuana possession after being stopped by police.

After pulling over the van the men were driving, police on the scene reportedly detected the unmistakable aroma of pot smoke wafting from the vehicle. When the cops searched the van, they discovered small amounts of pot, THC edible gummy candies, and several backpacks full of cash.

FBI agents had already been looking for the men, who were allegedly caught on surveillance footage tinkering with cash machines in Wyoming, Colorado and Utah, shortly before those ATMs were relieved of tens of thousands of dollars.

According to a complaint filed in the U.S. District Court for the District of Colorado, the men first hit an ATM at a credit union in Parker, Colo. on October 10, 2017. The robbery occurred after business hours, but the cash machine in question was located in a vestibule available to customers 24/7.

The complaint says surveillance videos showed the men opening the top of the ATM, which housed the computer and hard drive for the ATM — but not the secured vault where the cash was stored. The video showed the subjects reaching into the ATM, and then closing it and exiting the vestibule. On the video, one of the subjects appears to be carrying an object consistent with the size and appearance of the hard drive from the ATM.

Approximately ten minutes later, the subjects returned and opened up the cash machine again. Then they closed the top of the ATM and appeared to wait while the ATM computer restarted. After that, both subjects could be seen on the video using their mobile phones. One of the subjects reportedly appeared to be holding a small wireless mini-computer keyboard.

Soon after, the ATM began spitting out cash, netting the thieves more than $24,000. When they they were done, the suspects allegedly retrieved their equipment from the ATM and left.

Forensic analysis of the ATM hard drive determined that the thieves installed the Ploutus.D malware on the cash machine’s hard drive. Ploutus.D is an advanced malware strain that lets crooks interact directly with the ATM’s computer and force it to dispense money.

“Often the malware requires entering of codes to dispense cash,” reads an FBI affidavit (PDF). “These codes can be obtained by a third party, not at the location, who then provides the codes to the subjects at the ATM. This allows the third party to know how much cash is dispensed from the ATM, preventing those who are physically at the ATM from keeping cash for themselves instead of providing it to the criminal organization. The use of mobile phones is often used to obtain these dispensing codes.” Continue reading →

Expert: IoT Botnets the Work of a ‘Vast Minority’

In December 2017, the U.S. Department of Justice announced indictments and guilty pleas by three men in the United States responsible for creating and using Mirai, a malware strain that enslaves poorly-secured “Internet of Things” or IoT devices like security cameras and digital video recorders for use in large-scale cyberattacks.

The FBI and the DOJ had help in their investigation from many security experts, but this post focuses on one expert whose research into the Dark Web and its various malefactors was especially useful in that case. Allison Nixon is director of security research at Flashpoint, a cyber intelligence firm based in New York City. Nixon spoke with KrebsOnSecurity at length about her perspectives on IoT security and the vital role of law enforcement in this fight.

Brian Krebs (BK): Where are we today with respect to IoT security? Are we better off than were a year ago, or is the problem only worse?

Allison Nixon (AN): In some aspects we’re better off. The arrests that happened over the last year in the DDoS space, I would call that a good start, but we’re not out of the woods yet and we’re nowhere near the end of anything.

BK: Why not?

AN: Ultimately, what’s going with these IoT botnets is crime. People are talking about these cybersecurity problems — problems with the devices, etc. — but at the end of the day it’s crime and private citizens don’t have the power to make these bad actors stop.

BK: Certainly security professionals like yourself and others can be diligent about tracking the worst actors and the crime machines they’re using, and in reporting those systems when it’s advantageous to do so?

AN: That’s a fair argument. I can send abuse complaints to servers being used maliciously. And people can write articles that name individuals. However, it’s still a limited kind of impact. I’ve seen people get named in public and instead of stopping, what they do is improve their opsec [operational security measures] and keep doing the same thing but just sneakier. In the private sector, we can frustrate things, but we can’t actually stop them in the permanent, sanctioned way that law enforcement can. We don’t really have that kind of control.

BK: How are we not better off?

AN: I would say that as time progresses, the community that practices DDoS and malicious hacking and these pointless destructive attacks get more technically proficient when they’re executing attacks, and they just become a more difficult adversary.

BK: A more difficult adversary?

AN: Well, if you look at the individuals that were the subject of the announcement this month, and you look in their past, you can see they’ve been active in the hacking community a long time. Litespeed [the nickname used by Josiah White, one of the men who pleaded guilty to authoring Mirai] has been credited with lots of code.  He’s had years to develop and as far as I could tell he didn’t stop doing criminal activity until he got picked up by law enforcement.

BK: It seems to me that the Mirai authors probably would not have been caught had they never released the source code for their malware. They said they were doing so because multiple law enforcement agencies and security researchers were hot on their trail and they didn’t want to be the only ones holding the source code when the cops showed up at their door. But if that was really their goal in releasing it, doing so seems to have had the exact opposite effect. What’s your take on that?

AN: You are absolutely, 100 million percent correct. If they just shut everything down and left, they’d be fine now. The fact that they dumped the source was a tipping point of sorts. The damages they caused at that time were massive, but when they dumped the source code the amount of damage their actions contributed to ballooned [due to the proliferation of copycat Mirai botnets]. The charges against them specified their actions in infecting the machines they controlled, but when it comes to what interested researchers in the private sector, the moment they dumped the source code — that’s the most harmful act they did out of the entire thing.

BK: Do you believe their claimed reason for releasing the code?

AN: I believe it. They claimed they released it because they wanted to hamper investigative efforts to find them. The problem is that not only is it incorrect, it also doesn’t take into account the researchers on the other end of the spectrum who have to pick from many targets to spend their time looking at. Releasing the source code changed that dramatically. It was like catnip to researchers, and was just a new thing for researchers to look at and play with and wonder who wrote it.

If they really wanted to stay off law enforcement’s radar, they would be as low profile as they could and not be interesting. But they did everything wrong: They dumped the source code and attacked a security researcher using tools that are interesting to security researchers. That’s like attacking a dog with a steak. I’m going to wave this big juicy steak at a dog and that will teach him. They made every single mistake in the book.

BK: What do you think it is about these guys that leads them to this kind of behavior? Is it just a kind of inertia that inexorably leads them down a slippery slope if they don’t have some kind of intervention?

AN: These people go down a life path that does not lead them to a legitimate livelihood. They keep doing this and get better at it and they start to do these things that really can threaten the Internet as a whole. In the case of these DDoS botnets, it’s worrying that these individuals are allowed to go this deep before law enforcement catches them. Continue reading →

Canadian Police Charge Operator of Hacked Password Service Leakedsource.com

Canadian authorities have arrested and charged a 27-year-old Ontario man for allegedly selling billions of stolen passwords online through the now-defunct service Leakedsource.com.

The now-defunct Leakedsource service.

On Dec. 22, 2017, the Royal Canadian Mounted Police (RCMP) charged Jordan Evan Bloom of Thornhill, Ontario for trafficking in identity information, unauthorized use of a computer, mischief to data, and possession of property obtained by crime. Bloom is expected to make his first court appearance today.

According to a statement from the RCMP, “Project Adoration” began in 2016 when the RCMP learned that LeakedSource.com was being hosted by servers located in Quebec.

“This investigation is related to claims about a website operator alleged to have made hundreds of thousands of dollars selling personal information,” said Rafael Alvarado, the officer in charge of the RCMP Cybercrime Investigative Team. “The RCMP will continue to work diligently with our domestic and international law enforcement partners to prosecute online criminality.”

In January 2017, multiple news outlets reported that unspecified law enforcement officials had seized the servers for Leakedsource.com, perhaps the largest online collection of usernames and passwords leaked or stolen in some of the worst data breaches — including three billion credentials for accounts at top sites like LinkedIn and Myspace.

LeakedSource in October 2015 began selling access to passwords stolen in high-profile breaches. Enter any email address on the site’s search page and it would tell you if it had a password corresponding to that address. However, users had to select a payment plan before viewing any passwords.

The RCMP alleges that Jordan Evan Bloom was responsible for administering the LeakedSource.com website, and earned approximately $247,000 from trafficking identity information.

A February 2017 story here at KrebsOnSecurity examined clues that LeakedSource was administered by an individual in the United States.  Multiple sources suggested that one of the administrators of LeakedSource also was the admin of abusewith[dot]us, a site unabashedly dedicated to helping people hack email and online gaming accounts.

Hack of Attack-for-Hire Service vDOS Snares New Mexico Man

A New Mexico man is facing federal hacking charges for allegedly using the now defunct attack-for-hire service vDOS to launch damaging digital assaults aimed at knocking his former employer’s Web site offline. Prosecutors were able to bring the case in part because vDOS got massively hacked last year, and its customer database of payments and targets leaked to this author and to the FBI.

Prosecutors in Minnesota have charged John Kelsey Gammell, 46, with using vDOS and other online attack services to hurl a year’s worth of attack traffic at the Web sites associated with Washburn Computer Group, a Minnesota-based company where Gammell used to work.

vDOS as it existed on Sept. 8, 2016.

vDOS existed for nearly four years, and was known as one of the most powerful and effective pay-to-play tools for launching distributed denial-of-service (DDoS) attacks. The vDOS owners used a variety of methods to power their service, including at least one massive botnet consisting of tens of thousands of hacked Internet of Things (IoT) devices, such as compromised Internet routers and security cameras. vDOS also was used in numerous DDoS attacks against this site.

Investigators allege that although Gammell used various methods to hide his identity, email addresses traced back to him were found in the hacked user and target databases from vDOS.

More importantly, prosecutors say, someone began taunting Washburn via Yahoo and Gmail messages while the attacks were underway, asking how everything was going at the company and whether the IT department needed any help.

“Also attached to this second email was an image of a mouse laughing,” the Justice Department indictment (PDF) alleges. “Grand jury subpoenas for subscriber information were subsequently served on Google…and Yahoo. Analysis of the results showed information connecting both accounts to an individual named John Gammell. Both email addresses were created using the cell phone number 612-205-8609.”

The complaint notes that the government subpoenaed AT&T for subscriber information and traced that back to Gammell as well, but phone number also is currently listed as the recovery number for a Facebook account tied to John K. Gammell.

That Facebook account features numerous references to the hacker collective known as Anonymous. This is notable because according to the government Gammell used two different accounts at vDOS: One named “AnonCunnilingus” and another called “anonrooster.” The email addresses this user supplied when signing up at vDOS (jkgammell@gmail.com and jkgammell@icloud.com) include other addresses quite clearly tied to multiple accounts for John K. Gammell.

John K. Gammell’s Facebook account.

Below is a snippet from a customer service ticket that the AnonCunnilingus account filed in Aug. 2015

“Dear Colleagues, this is Mr. Cunnilingus. You underestimate your capabilities. Contrary to your statement of “Notice!” It appears from our review that you are trying to stress test a DDoS protected host, vDOS stresser is not capable of taking DDoS protected hosts down which means you will not be able to drop this hosting using vDOS stresser…As they do not have my consent to use my internet, after their site being down for two days, they changed their IP and used rackspace DDoS mitigation and must now be removed from cyberspace. Verified by downbyeveryone. We will do much business. Thank you for your outstanding product 🙂 We Are Anonymous USA.”

Gammell has pleaded not guilty to the charges. He has not responded to requests for comment. The indictment states that Gammell allegedly attacked at least a half-dozen other companies over a year-long period between mid-2015 and July 2016, including several banks and two other companies at which he either previously worked or with whom he’d interviewed for a job.

Who Is Marcus Hutchins?

In early August 2017, FBI agents in Las Vegas arrested 23-year-old British security researcher Marcus Hutchins on suspicion of authoring and/or selling “Kronos,” a strain of malware designed to steal online banking credentials. Hutchins was virtually unknown to most in the security community until May 2017 when the U.K. media revealed him as the “accidental hero” who inadvertently halted the global spread of WannaCry, a ransomware contagion that had taken the world by storm just days before.

Relatively few knew it before his arrest, but Hutchins has for many years authored the popular cybersecurity blog MalwareTech. When this fact became more widely known — combined with his hero status for halting Wannacry — a great many MalwareTech readers quickly leapt to his defense to denounce his arrest. They reasoned that the government’s case was built on flimsy and scant evidence, noting that Hutchins has worked tirelessly to expose cybercriminals and their malicious tools. To date, some 226 supporters have donated more than $14,000 to his defense fund.

At first, I did not believe the charges against Hutchins would hold up under scrutiny. But as I began to dig deeper into the history tied to dozens of hacker forum pseudonyms, email addresses and domains he apparently used over the past decade, a very different picture began to emerge.

In this post, I will attempt to describe and illustrate more than three weeks’ worth of connecting the dots from what appear to be Hutchins’ earliest hacker forum accounts to his real-life identity. The clues suggest that Hutchins began developing and selling malware in his mid-teens — only to later develop a change of heart and earnestly endeavor to leave that part of his life squarely in the rearview mirror.

GH0STHOSTING/IARKEY

I began this investigation with a simple search of domain name registration records at domaintools.com [full disclosure: Domain Tools recently was an advertiser on this site]. A search for “Marcus Hutchins” turned up a half dozen domains registered to a U.K. resident by the same name who supplied the email address “surfallday2day@hotmail.co.uk.”

One of those domains — Gh0sthosting[dot]com (the third character in that domain is a zero) — corresponds to a hosting service that was advertised and sold circa 2009-2010 on Hackforums[dot]net, a massively popular forum overrun with young, impressionable men who desperately wish to be elite coders or hackers (or at least recognized as such by their peers).

The surfallday2day@hotmail.co.uk address tied to Gh0sthosting’s initial domain registration records also was used to register a Skype account named Iarkey that listed its alias as “Marcus.” A Twitter account registered in 2009 under the nickname “Iarkey” points to Gh0sthosting[dot]com.

Gh0sthosting was sold by a Hackforums user who used the same Iarkey nickname, and in 2009 Iarkey told fellow Hackforums users in a sales thread for his business that Gh0sthosting was “mainly for blackhats wanting to phish.” In a separate post just a few days apart from that sales thread, Iarkey responds that he is “only 15” years old, and in another he confirms that his email address is surfallday2day@hotmail.co.uk.

daloseronly15

A review of the historic reputation tied to the Gh0sthosting domain suggests that at least some customers took Iarkey up on his offer: Malwaredomainlist.com, for example, shows that around this same time in 2009 Gh0sthosting was observed hosting plenty of malware, including trojan horse programs, phishing pages and malware exploits.

A “reverse WHOIS” search at Domaintools.com shows that Iarkey’s surfallday2day email address was used initially to register several other domains, including uploadwith[dot]us and thecodebases[dot]com.

Shortly after registering Gh0sthosting and other domains tied to his surfallday2day@hotmail.co.uk address, Iarkey evidently thought better of including his real name and email address in his domain name registration records. Thecodebases[dot]com, for example, changed its WHOIS ownership to a “James Green” in the U.K., and switched the email to “herpderpderp2@hotmail.co.uk.”

A reverse WHOIS lookup at domaintools.com for that email address shows it was used to register a Hackforums parody (or phishing?) site called Heckforums[dot]net. The domain records showed this address was tied to a Hackforums clique called “Atthackers.” The records also listed a Michael Chanata from Florida as the owner. We’ll come back to Michael Chanata and Atthackers at the end of this post. Continue reading →

How a Citadel Trojan Developer Got Busted

A U.S. District Court judge in Atlanta last week handed a five year prison sentence to Mark Vartanyan, a Russian hacker who helped develop and sell the once infamous and widespread Citadel banking trojan. This fact has been reported by countless media outlets, but far less well known is the fascinating backstory about how Vartanyan got caught.

For several years, Citadel ruled the malware scene for criminals engaged in stealing online banking passwords and emptying bank accounts. U.S. prosecutors say Citadel infected more than 11 million computers worldwide, causing financial losses of at least a half billion dollars.

Like most complex banking trojans, Citadel was marketed and sold in secluded, underground cybercrime markets. Often the most time-consuming and costly aspect of malware sales and development is helping customers with any tech support problems they may have in using the crimeware.

In light of that, one innovation that Citadel brought to the table was to crowdsource some of this support work, easing the burden on the malware’s developers and freeing them up to spend more time improving their creations and adding new features.

Citadel users discuss the merits of including a module to remove other parasites from host PCs.

Citadel users discuss the merits of including a module to remove other parasites from host PCs.

Citadel boasted an online tech support system for customers designed to let them file bug reports, suggest and vote on new features in upcoming malware versions, and track trouble tickets that could be worked on by the malware developers and fellow Citadel users alike. Citadel customers also could use the system to chat and compare notes with fellow users of the malware.

It was this very interactive nature of Citadel’s support infrastructure that FBI agents would ultimately use to locate and identify Vartanyan, who went by the nickname “Kolypto.” The nickname of the core seller of Citadel was “Aquabox,” and the FBI was keen to identify Aquabox and any programmers he’d hired to help develop Citadel.

In June 2012, FBI agents bought several licenses of Citadel from Aquabox, and soon the agents were suggesting tweaks to the malware that they could use to their advantage. Posing as an active user of the malware, FBI agents informed the Citadel developers that they’d discovered a security vulnerability in the Web-based interface that Citadel customers used to keep track of and collect passwords from infected systems (see screenshot below).

Exclusive: Dutch Cops on AlphaBay ‘Refugees’

Following today’s breaking news about U.S. and international authorities taking down the competing Dark Web drug bazaars AlphaBay and Hansa Market, KrebsOnSecurity caught up with the Dutch investigators who took over Hansa on June 20, 2017. When U.S. authorities shuttered AlphaBay on July 5, police in The Netherlands saw a massive influx of AlphaBay refugees who were unwittingly fleeing directly into the arms of investigators. What follows are snippets from an exclusive interview with Petra Haandrikman, team leader of the Dutch police unit that infiltrated Hansa.

Vendors on both AlphaBay and Hansa sold a range of black market items — most especially controlled substances like heroin. According to the U.S. Justice Department, AlphaBay alone had some 40,000 vendors who marketed a quarter-million sales listings for illegal drugs to more than 200,000 customers. The DOJ said that as of earlier this year, AlphaBay had 238 vendors selling heroin. Another 122 vendors advertised Fentanyl, an extremely potent synthetic opioid that has been linked to countless overdoses and deaths.

In our interview, Haandrikman detailed the dual challenges of simultaneously dealing with the exodus of AlphaBay users to Hansa and keeping tabs on the giant increase in new illicit drug orders that were coming in daily as a result.

KrebsOnSecurity (K): Talk a bit about how your team was able to seize control over Hansa.

Haandrikman (H): When we knew the FBI was working on AlphaBay, we thought ‘What’s better than if they come to us?’ The FBI wanted [the AlphaBay takedown] to look like an exit scam [where the proprietors of a dark web marketplace suddenly abscond with everyone’s money]. And we knew a lot of vendors on AlphaBay would probably come over to Hansa when AlphaBay was closed.

K: Where was Hansa physically based?

H: We knew the Hansa servers were in Lithuania, so we sent an MLAT (mutual legal assistance treaty) request to Lithuania and requested if we could proceed with our planned actions in their country. They were very willing to help us in our investigations.

K: So you made a copy of the Hansa servers?

H: We gained physical access to the machines in Lithuania, and were able to set up some clustering between the [Hansa] database servers in Lithuania and servers we were running in our country. With that, we were able to get a real time copy of the Hansa database, and then copy over the Web site code itself.

K: Did you have to take Hansa offline for a while during this process?

H: No, it didn’t really go offline. We were able to create our own copy of the site that was running on servers in the Netherlands. So there were two copies of the site running simultaneously.

The now-defunct Hansa Market.

The now-defunct Hansa Market.

K: At a press conference on this effort at the U.S. Justice Department in Washington, D.C. today, Rob Wainwright, director of the European law enforcement organization Europol, detailed how the closure of AlphaBay caused a virtual stampede of former AlphaBay buyers and sellers taking their business to Hansa Market. Tell us more about what that influx was like, and how you handled it.

H: Yes, we called them “AlphaBay refugees.” It wasn’t the technical challenge that caused problems. Because this was a police operation, we wanted to keep up with the orders to see if there were any large amounts [of drugs] being ordered to one place, [so that] we could share information with our law enforcement partners internationally.

K: How exactly did you deal with that? Were you able to somehow slow down the orders coming in?

H: We just closed registration on Hansa for new users for a few days. So there was a temporary restriction for being able to register on the site, which slowed down the orders each day to make sure that we could cope with the orders that were coming in.

K: Did anything unexpected happen as a result?

H: Some people started selling their Hansa accounts on Reddit. I read somewhere that one Hansa user sold his account for $40. The funny part about that was that sale happened about five minutes before we re-opened registration. There was a lot of frustration from ex-AlphaBay users that weren’t allowed to register on the site. But we also got defended by the Hansa community on social media, who said it was a great decision by us to educate certain AlphaBay users on Hansa etiquette, which doesn’t allow the sale of things permitted on AlphaBay and other dark markets, such as child pornography and firearms.

FBI: Extortion, CEO Fraud Among Top Online Fraud Complaints in 2016

Online extortion, tech support scams and phishing attacks that spoof the boss were among the most costly cyber scams reported by consumers and businesses last year, according to new figures from the FBI’s Internet Crime Complaint Center (IC3).

The IC3 report released Thursday correctly identifies some of the most prevalent and insidious forms of cybercrimes today, but the total financial losses tied to each crime type also underscore how infrequently victims actually report such crimes to law enforcement.

Source: Internet Crime Complaint Center (IC3).

Source: Internet Crime Complaint Center (IC3).

For example, the IC3 said it received 17,146 extortion-related complaints, with an adjusted financial loss totaling just over $15 million. In that category, the report identified 2,673 complaints identified as ransomware — malicious software that scrambles a victim’s most important files and holds them hostage unless and until the victim pays a ransom (usually in a virtual currency like Bitcoin).

According to the IC3, the losses associated with those ransomware complaints totaled slightly more than $2.4 million. Writing for BleepingComputer.com — a tech support forum I’ve long recommended that helps countless ransomware victims — Catalin Cimpanu observes that the FBI’s ransomware numbers “are ridiculously small compared to what happens in the real world, where ransomware is one of today’s most prevalent cyber-threats.”

“The only explanation is that people are paying ransoms, restoring from backups, or reinstalling PCs without filing a complaint with authorities,” Cimpanu writes.

It’s difficult to know how what percentage of ransomware victims paid the ransom or were able to restore from backups, but one thing is for sure: Relatively few victims are reporting cyber fraud to federal investigators.

The report notes that only an estimated 15 percent of the nation’s fraud victims report their crimes to law enforcement. For 2016, 298,728 complaints were received, with a total victim loss of $1.33 billion.

If that 15 percent estimate is close to accurate, that means the real cost of cyber fraud for Americans last year was probably closer to $9 billion, and the losses from ransomware attacks upwards of $16 million. Continue reading →

Blind Trust in Email Could Cost You Your Home

The process of buying or selling a home can be extremely stressful and complex, but imagine the stress that would boil up if — at settlement — your money was wired to scammers in another country instead of to the settlement firm or escrow company. Here’s the story about a phishing email that cost a couple their home and left them scrambling for months to recover hundreds of thousands in cash that went missing.

It was late November 2016, and Jon and Dorothy Little were all set to close on a $200,000 home in Hendersonville, North Carolina. Just prior to the closing date on Dec. 2 their realtor sent an email to the Little’s and to the law firm handling the closing, asking the settlement firm for instructions on wiring the money to an escrow account.

The fraudulent wire instructions apparently sent by the hackers via the settlement law firm.

The fraudulent wire instructions apparently sent by the hackers via the settlement law firm.

An attorney with the closing firm responded with wiring instructions as requested, attaching a document that had the law firm’s logo and some bank account information that was represented as the seller’s account number. The Little’s realtor sent the wire on Thursday morning, the day before settlement.

“We went to closing at 1 p.m. on Friday, and after we signed all the papers, we asked the lawyers if we were going to get back the extra money we had sent them, because they hadn’t be able to give us an exact amount in the wiring instructions. At that point they told us they had never gotten the money.”

After some disagreement, both legitimate parties to the transaction agreed that someone’s email had been hacked by the fraudsters, and was used to divert the wired funds to an account the criminals controlled. The hackers had forged a copy of the law firm’s letterhead, and beneath it placed their own Bank of America account information (see screen shot above).

The owner of the Bank of America account appears to have been a willing or unwitting accomplice — also know as a “money mule” — recruited through work-at-home job schemes to receive and forward funds stolen from hacked business accounts. In this case, the money mule wired all but 10 percent of the money (a typical money mule commission) to an account at TD Bank.

Fortunately for the Littles, the FBI succeeded in having the resulting $180,000 wire transfer frozen once it hit the TD Bank account. However, efforts to recover the stolen funds were stymied immediately when the Littles’ credit union refused to give Bank of America a so-called “hold harmless” agreement that the bigger bank wanted as a legal guarantee before agreeing to help.

Charisse Castagnoli, an adjunct professor of law at the John Marshall Law School, said banks have a fiduciary duty to their customers to honor their requests in good faith, and as such they tend to be very nervous legally about colluding with another bank to reverse payment instructions by one of their own customers. The “hold harmless” agreement is usually sought by the bank which received a fraudulent wire transfer, Castagnoli said, and it requires the responding bank to assume any and all liability for costs that the requesting bank may later incur should the owner of account which received the fraudulent wire decide to dispute the payment reversal.

“When it comes to wire fraud cases the banks have to move very quickly because once the wires make it outside the U.S. to foreign banks, the money is usually as good as gone,” Castagnoli said. “The receiver or transferee usually insists on a hold harmless agreement because they’re moving the money on behalf of their own account holder, kind of going against their own client which is a big ‘no-no’ when you’re a fiduciary.”

But in this case, the credit union in which the Littles had invested virtually all of their money for more than 40 years decided it could not in good faith provide that hold harmless agreement, because doing so would stipulate that the credit union affirms the victim (the Littles) hadn’t willingly and knowing initiated the wire, when in fact they had.

“I talked to the wire dept multiple times,” Mr. Little said of the folks at his financial institution, Atlanta, Ga.-based Delta Community Credit Union (DCCU). “They finally put me through to the vice president of loss prevention at the credit union. I’m not sure they even believed all that was going on. They finally came back and told me they couldn’t do it. Their rules would not allow them to send a hold harmless letter because I had asked them to do something and they had done it. They had a big meeting last week with apparently the CEO of the credit union and several other people. Then they called me on Monday again and told me they would not could not do it.” Continue reading →

The Backstory Behind Carder Kingpin Roman Seleznev’s Record 27 Year Prison Sentence

Roman Seleznev, a 32-year-old Russian cybercriminal and prolific credit card thief, was sentenced Friday to 27 years in federal prison. That is a record punishment for hacking violations in the United States and by all accounts one designed to send a message to criminal hackers everywhere. But a close review of the case suggests that Seleznev’s record sentence was severe in large part because the evidence against him was substantial and yet he declined to cooperate with prosecutors prior to his trial.

The son of an influential Russian politician, Seleznev made international headlines in 2014 after he was captured while vacationing in The Maldives, a popular vacation spot for Russians and one that many Russian cybercriminals previously considered to be out of reach for western law enforcement agencies.

However, U.S. authorities were able to negotiate a secret deal with the Maldivian government to apprehend Seleznev. Following his capture, Seleznev was whisked away to Guam for more than a month before being transported to Washington state to stand trial for computer hacking charges.

The U.S. Justice Department says the laptop found with him when he was arrested contained more than 1.7 million stolen credit card numbers, and that evidence presented at trial showed that Seleznev earned tens of millions of dollars defrauding more than 3,400 financial institutions.

Investigators also reportedly found a smoking gun: a password cheat sheet that linked Seleznev to a decade’s worth of criminal hacking.

Seleznev was initially identified as a major cybercriminal by U.S. government investigators in 2011, when prosecutors in Nevada named him as part of a conspiracy involving more than three dozen popular merchants on carder[dot]su, a bustling fraud forum where he and other members openly marketed various cybercrime-oriented services.

Known by the hacker handle “nCux,” Seleznev operated multiple online shops that sold stolen credit and debit card data. According to Seleznev’s indictment in the Nevada case, he was part of a group that hacked into restaurants between 2009 and 2011 and planted malicious software to steal card data from store point-of-sale devices.

In Seattle on Aug. 25, 2016, Seleznev was convicted of 10 counts of wire fraud, eight counts of intentional damage to a protected computer, nine counts of obtaining information from a protected computer, nine counts of possession of 15 or more unauthorized access devices and two counts of aggravated identity theft.

“Simply put, Roman Seleznev has harmed more victims and caused more financial loss than perhaps any other defendant that has appeared before the court,” federal prosecutors charged in their sentencing memorandum. “This prosecution is unprecedented.”

Seleznev’s lawyer Igor Litvak called his client’s sentence “draconian,” saying that Seleznev was gravely injured in a 2011 terrorist attack in Morocco, has Hepatitis B and is not well physically.

Litvak noted that his client also faces two more prosecutions — in Georgia and Nevada, and that his client is likely to be shipped off to Nevada soon.

“It’s unprecedented, yes, but it’s also a draconian sentence for a person who is very gravely ill,” Litvak said in an interview with KrebsOnSecurity. “He’s not going to live that long. He’s going to die in jail. I’m certain of that.”
