Amid an Embarrassment of Riches, Ransom Gangs Increasingly Outsource Their Work

October 8, 2020

There’s an old adage in information security: “Every company gets penetration tested, whether or not they pay someone for the pleasure.” Many organizations that do hire professionals to test their network security posture unfortunately tend to focus on fixing vulnerabilities hackers could use to break in. But judging from the proliferation of help-wanted ads for offensive pentesters in the cybercrime underground, today’s attackers have exactly zero trouble gaining that initial intrusion: The real challenge seems to be hiring enough people to help everyone profit from the access already gained.

One of the most common ways such access is monetized these days is through ransomware, which holds a victim’s data and/or computers hostage unless and until an extortion payment is made. But in most cases, there is a yawning gap of days, weeks or months between the initial intrusion and the deployment of ransomware within a victim organization.

That’s because it usually takes time and a good deal of effort for intruders to get from a single infected PC to seizing control over enough resources within the victim organization where it makes sense to launch the ransomware.

This includes pivoting from or converting a single compromised Microsoft Windows user account to an administrator account with greater privileges on the target network; the ability to sidestep and/or disable any security software; and gaining the access needed to disrupt or corrupt any data backup systems the victim firm may have.

Each day, millions of malware-laced emails are blasted out containing booby-trapped attachments. If the attachment is opened, the malicious document proceeds to quietly download additional malware and hacking tools to the victim machine (here’s one video example of a malicious Microsoft Office attachment from the malware sandbox service any.run). From there, the infected system will report home to a malware control server operated by the spammers who sent the missive.

At that point, control over the victim machine may be transferred or sold multiple times between different cybercriminals who specialize in exploiting such access. These folks are very often contractors who work with established ransomware groups, and who are paid a set percentage of any eventual ransom payments made by a victim company.

THE DOCTOR IS IN

Enter subcontractors like “Dr. Samuil,” a cybercriminal who has maintained a presence on more than a dozen top Russian-language cybercrime forums over the past 15 years. In a series of recent advertisements, Dr. Samuil says he’s eagerly hiring experienced people who are familiar with tools used by legitimate pentesters for exploiting access once inside of a target company — specifically, post-exploit frameworks like the closely-guarded Cobalt Strike.

“You will be regularly provided select accesses which were audited (these are about 10-15 accesses out of 100) and are worth a try,” Dr. Samuil wrote in one such help-wanted ad. “This helps everyone involved to save time. We also have private software that bypasses protection and provides for smooth performance.”

From other classified ads he posted in August and September 2020, it seems clear Dr. Samuil’s team has some kind of privileged access to financial data on targeted companies that gives them a better idea of how much cash the victim firm may have on hand to pay a ransom demand. To wit:

“There is huge insider information on the companies which we target, including information if there are tape drives and clouds (for example, Datto that is built to last, etc.), which significantly affects the scale of the conversion rate.

Requirements:
– experience with cloud storage, ESXi.
– experience with Active Directory.
– privilege escalation on accounts with limited rights.

* Serious level of insider information on the companies with which we work. There are proofs of large payments, but only for verified LEADs.
* There is also a private MEGA INSIDE , which I will not write about here in public, and it is only for experienced LEADs with their teams.
* We do not look at REVENUE / NET INCOME / Accountant reports, this is our MEGA INSIDE, in which we know exactly how much to confidently squeeze to the maximum in total.

According to cybersecurity firm Intel 471, Dr. Samuil’s ad is hardly unique, and there are several other seasoned cybercriminals who are customers of popular ransomware-as-a-service offerings that are hiring sub-contractors to farm out some of the grunt work.

“Within the cybercriminal underground, compromised accesses to organizations are readily bought, sold and traded,” Intel 471 CEO Mark Arena said. “A number of security professionals have previously sought to downplay the business impact cybercriminals can have to their organizations.”

“But because of the rapidly growing market for compromised accesses and the fact that these could be sold to anyone, organizations need to focus more on efforts to understand, detect and quickly respond to network compromises,” Arena continued. “That covers faster patching of the vulnerabilities that matter, ongoing detection and monitoring for criminal malware, and understanding the malware you are seeing in your environment, how it got there, and what it has or could have dropped subsequently.” Continue reading

Promising Infusions of Cash, Fake Investor John Bernard Walked Away With $30M

October 7, 2020

September featured two stories on a phony tech investor named John Bernard, a pseudonym used by a convicted thief named John Clifton Davies who’s fleeced dozens of technology companies out of an estimated $30 million with the promise of lucrative investments. Those stories prompted a flood of tips from Davies’ victims that paints a much clearer picture of this serial con man and his cohorts, including allegations of hacking, smuggling, bank fraud and murder.

KrebsOnSecurity interviewed more than a dozen of Davies’ victims over the past five years, none of whom wished to be quoted here out of fear of reprisals from a man they say runs with mercenaries and has connections to organized crime.

As described in Part II of this series, John Bernard is in fact John Clifton Davies, a 59-year-old U.K. citizen who absconded from justice before being convicted on multiple counts of fraud in 2015. Prior to his conviction, Davies served 16 months in jail before being cleared of murdering his third wife on their honeymoon in India.

The scam artist John Bernard (left) in a recent Zoom call, and a photo of John Clifton Davies from 2015.

After eluding justice in the U.K., Davies reinvented himself as The Private Office of John Bernard, pretending to a be billionaire Swiss investor who made his fortunes in the dot-com boom 20 years ago and who was seeking investment opportunities.

In case after case, Bernard would promise to invest millions in tech startups, and then insist that companies pay tens of thousands of dollars worth of due diligence fees up front. However, the due diligence company he insisted on using — another Swiss firm called Inside Knowledge — also was secretly owned by Bernard, who would invariably pull out of the deal after receiving the due diligence money.

Bernard found a constant stream of new marks by offering extraordinarily generous finders fees to investment brokers who could introduce him to companies seeking an infusion of cash. When it came time for companies to sign legal documents, Bernard’s victims interacted with a 40-something Inside Knowledge employee named “Katherine Miller,” who claimed to be his lawyer.

It turns out that Katherine Miller is a onetime Moldovan attorney who was previously known as Ecaterina “Katya” Dudorenko. She is listed as a Romanian lawyer in the U.K. Companies House records for several companies tied to John Bernard, including Inside Knowledge Solutions Ltd., Docklands Enterprise Ltd., and Secure Swiss Data Ltd (more on Secure Swiss data in a moment).

Another of Bernard’s associates listed as a director at Docklands Enterprise Ltd. is Sergey Valentinov Pankov. This is notable because in 2018, Pankov and Dudorenko were convicted of cigarette smuggling in the United Kingdom.

According to the Organized Crime and Corruption Reporting Project, “illicit trafficking of tobacco is a multibillion-dollar business today, fueling organized crime and corruption [and] robbing governments of needed tax money. So profitable is the trade that tobacco is the world’s most widely smuggled legal substance. This booming business now stretches from counterfeiters in China and renegade factories in Russia to Indian reservations in New York and warlords in Pakistan and North Africa.”

Like their erstwhile boss Mr. Davies, both Pankov and Dudorenko disappeared before their convictions in the U.K. They were sentenced in absentia to two and a half years in prison.

Incidentally, Davies was detained by Ukrainian authorities in 2018, although he is not mentioned by name in this story from the Ukrainian daily Pravda. The story notes that the suspect moved to Kiev in 2014 and lived in a rented apartment with his Ukrainian wife. Continue reading

Attacks Aimed at Disrupting the Trickbot Botnet

October 2, 2020

Over the past 10 days, someone has been launching a series of coordinated attacks designed to disrupt Trickbot, an enormous collection of more than two million malware-infected Windows PCs that are constantly being harvested for financial data and are often used as the entry point for deploying ransomware within compromised organizations.

A text snippet from one of the bogus Trickbot configuration updates. Source: Intel 471

On Sept. 22, someone pushed out a new configuration file to Windows computers currently infected with Trickbot. The crooks running the Trickbot botnet typically use these config files to pass new instructions to their fleet of infected PCs, such as the Internet address where hacked systems should download new updates to the malware.

But the new configuration file pushed on Sept. 22 told all systems infected with Trickbot that their new malware control server had the address 127.0.0.1, which is a “localhost” address that is not reachable over the public Internet, according to an analysis by cyber intelligence firm Intel 471.

It’s not known how many Trickbot-infected systems received the phony update, but it seems clear this wasn’t just a mistake by Trickbot’s overlords. Intel 471 found that it happened yet again on Oct. 1, suggesting someone with access to the inner workings of the botnet was trying to disrupt its operations.

“Shortly after the bogus configs were pushed out, all Trickbot controllers stopped responding correctly to bot requests,” Intel 471 wrote in a note to its customers. “This possibly means central Trickbot controller infrastructure was disrupted. The close timing of both events suggested an intentional disruption of Trickbot botnet operations.”

Intel 471 CEO Mark Arena said it’s anyone’s guess at this point who is responsible.

“Obviously, someone is trying to attack Trickbot,” Arena said. “It could be someone in the security research community, a government, a disgruntled insider, or a rival cybercrime group. We just don’t know at this point.

Arena said it’s unclear how successful these bogus configuration file updates will be given that the Trickbot authors built a fail-safe recovery system into their malware. Specifically, Trickbot has a backup control mechanism: A domain name registered on EmerDNS, a decentralized domain name system.

“This domain should still be in control of the Trickbot operators and could potentially be used to recover bots,” Intel 471 wrote.

But whoever is screwing with the Trickbot purveyors appears to have adopted a multi-pronged approach: Around the same time as the second bogus configuration file update was pushed on Oct. 1, someone stuffed the control networks that the Trickbot operators use to keep track of data on infected systems with millions of new records.

Alex Holden is chief technology officer and founder of Hold Security, a Milwaukee-based cyber intelligence firm that helps recover stolen data. Holden said at the end of September Trickbot held passwords and financial data stolen from more than 2.7 million Windows PCs.

By October 1, Holden said, that number had magically grown to more than seven million.

“Someone is flooding the Trickbot system with fake data,” Holden said. “Whoever is doing this is generating records that include machine names indicating these are infected systems in a broad range of organizations, including the Department of Defense, U.S. Bank, JP Morgan Chase, PNC and Citigroup, to name a few.” Continue reading

Ransomware Victims That Pay Up Could Incur Steep Fines from Uncle Sam

October 1, 2020

Companies victimized by ransomware and firms that facilitate negotiations with ransomware extortionists could face steep fines from the U.S. federal government if the crooks who profit from the attack are already under economic sanctions, the Treasury Department warned today.

In its advisory (PDF), the Treasury’s Office of Foreign Assets Control (OFAC) said “companies that facilitate ransomware payments to cyber actors on behalf of victims, including financial institutions, cyber insurance firms, and companies involved in digital forensics and incident response, not only encourage future ransomware payment demands but also may risk violating OFAC regulations.”

As financial losses from cybercrime activity and ransomware attacks in particular have skyrocketed in recent years, the Treasury Department has imposed economic sanctions on several cybercriminals and cybercrime groups, effectively freezing all property and interests of these persons (subject to U.S. jurisdiction) and making it a crime to transact with them.

A number of those sanctioned have been closely tied with ransomware and malware attacks, including the North Korean Lazarus Group; two Iranians thought to be tied to the SamSam ransomware attacks; Evgeniy Bogachev, the developer of Cryptolocker; and Evil Corp, a Russian cybercriminal syndicate that has used malware to extract more than $100 million from victim businesses.

Those that run afoul of OFAC sanctions without a special dispensation or “license” from Treasury can face several legal repercussions, including fines of up to $20 million. Continue reading

Who’s Behind Monday’s 14-State 911 Outage?

September 29, 2020

Emergency 911 systems were down for more than an hour on Monday in towns and cities across 14 U.S. states. The outages led many news outlets to speculate the problem was related to Microsoft‘s Azure web services platform, which also was struggling with a widespread outage at the time. However, multiple sources tell KrebsOnSecurity the 911 issues stemmed from some kind of technical snafu involving Intrado and Lumen, two companies that together handle 911 calls for a broad swath of the United States.

Image: West.com

On the afternoon of Monday, Sept. 28, several states including Arizona, California, Colorado, Delaware, Florida, Illinois, Indiana, Minnesota, Nevada, North Carolina, North Dakota, Ohio, Pennsylvania and Washington reported 911 outages in various cities and localities.

Multiple news reports suggested the outages might have been related to an ongoing service disruption at Microsoft. But a spokesperson for the software giant told KrebsOnSecurity, “we’ve seen no indication that the multi-state 911 outage was a result of yesterday’s Azure service disruption.”

Inquiries made with emergency dispatch centers at several of the towns and cities hit by the 911 outage pointed to a different source: Omaha, Neb.-based Intrado — until last year known as West Safety Communications — a provider of 911 and emergency communications infrastructure, systems and services to telecommunications companies and public safety agencies throughout the country.

Intrado did not respond to multiple requests for comment. But according to officials in Henderson County, NC, which experienced its own 911 failures yesterday, Intrado said the outage was the result of a problem with an unspecified service provider.

“On September 28, 2020, at 4:30pm MT, our 911 Service Provider observed conditions internal to their network that resulted in impacts to 911 call delivery,” reads a statement Intrado provided to county officials. “The impact was mitigated, and service was restored and confirmed to be functional by 5:47PM MT.  Our service provider is currently working to determine root cause.”

The service provider referenced in Intrado’s statement appears to be Lumen, a communications firm and 911 provider that until very recently was known as CenturyLink Inc. A look at the company’s status page indicates multiple Lumen systems experienced total or partial service disruptions on Monday, including its private and internal cloud networks and its control systems network.

Lumen’s status page indicates the company’s private and internal cloud and control system networks had outages or service disruptions on Monday.

In a statement provided to KrebsOnSecurity, Lumen blamed the issue on Intrado.

“At approximately 4:30 p.m. MT, some Lumen customers were affected by a vendor partner event that impacted 911 services in AZ, CO, NC, ND, MN, SD, and UT,” the statement reads. “Service was restored in less than an hour and all 911 traffic is routing properly at this time. The vendor partner is in the process of investigating the event.”

It may be no accident that both of these companies are now operating under new names, as this would hardly be the first time a problem between the two of them has disrupted 911 access for a large number of Americans. Continue reading

Who is Tech Investor John Bernard?

September 25, 2020

John Bernard, the subject of a story here last week about a self-proclaimed millionaire investor who has bilked countless tech startups, appears to be a pseudonym for John Clifton Davies, a U.K. man who absconded from justice before being convicted on multiple counts of fraud in 2015. Prior to his conviction, Davies served 16 months in jail before being cleared of murdering his wife on their honeymoon in India.

The Private Office of John Bernard, which advertises itself as a capital investment firm based in Switzerland, has for years been listed on multiple investment sites as the home of a millionaire who made his fortunes in the dot-com boom 20 years ago and who has oodles of cash to invest in tech startups.

But as last week’s story noted, Bernard’s investment company is a bit like a bad slot machine that never pays out. KrebsOnSecurity interviewed multiple investment brokers who all told the same story: After promising to invest millions after one or two phone calls and with little or no pushback, Bernard would insist that companies pay tens of thousands of dollars worth of due diligence fees up front.

However, the due diligence company he insisted on using — another Swiss firm called Inside Knowledge — also was secretly owned by Bernard, who would invariably pull out of the deal after receiving the due diligence money.

Neither Mr. Bernard nor anyone from his various companies responded to multiple requests for comment over the past few weeks. What’s more, virtually all of the employee profiles tied to Bernard’s office have since last week removed those firms from their work experience as listed on their LinkedIn resumes — or else deleted their profiles altogether.

Sometime on Thursday John Bernard’s main website — the-private-office.ch — replaced the content on its homepage with a note saying it was closing up shop.

“We are pleased to announce that we are currently closing The Private Office fund as we have reached our intended investment level and that we now plan to focus on helping those companies we have invested into to grow and succeed,” the message reads.

As noted in last week’s story, the beauty of a scam like the one multiple investment brokers said was being run by Mr. Bernard is that companies bilked by small-time investment schemes rarely pursue legal action, mainly because the legal fees involved can quickly surpass the losses. What’s more, most victims will likely be too ashamed to come forward.

Also, John Bernard’s office typically did not reach out to investment brokers directly. Rather, he had his firm included on a list of angel investors focused on technology companies, so those seeking investments usually came to him.

Finally, multiple sources interviewed for this story said Bernard’s office offered a finders fee for any investment leads that brokers brought his way. While such commissions are not unusual, the amount promised — five percent of the total investment in a given firm that signed an agreement — is extremely generous. However, none of the investment brokers who spoke to KrebsOnSecurity were able to collect those fees, because Bernard’s office never actually consummated any of the deals they referred to him.

Microsoft: Attackers Exploiting ‘ZeroLogon’ Windows Flaw

September 24, 2020

Microsoft warned on Wednesday that malicious hackers are exploiting a particularly dangerous flaw in Windows Server systems that could be used to give attackers the keys to the kingdom inside a vulnerable corporate network. Microsoft’s warning comes just days after the U.S. Department of Homeland Security issued an emergency directive instructing all federal agencies to patch the vulnerability by Sept. 21 at the latest.

DHS’s Cybersecurity and Infrastructure Agency (CISA) said in the directive that it expected imminent exploitation of the flaw — CVE-2020-1472 and dubbed “ZeroLogon” — because exploit code which can be used to take advantage of it was circulating online.

Last night, Microsoft’s Security Intelligence unit tweeted that the company is “tracking threat actor activity using exploits for the CVE-2020-1472 Netlogon vulnerability.”

“We have observed attacks where public exploits have been incorporated into attacker playbooks,” Microsoft said. “We strongly recommend customers to immediately apply security updates.”

Microsoft released a patch for the vulnerability in August, but it is not uncommon for businesses to delay deploying updates for days or weeks while testing to ensure the fixes do not interfere with or disrupt specific applications and software.

CVE-2020-1472 earned Microsoft’s most-dire “critical” severity rating, meaning attackers can exploit it with little or no help from users. The flaw is present in most supported versions of Windows Server, from Server 2008 through Server 2019. Continue reading

Govt. Services Firm Tyler Technologies Hit in Apparent Ransomware Attack

September 23, 2020

Tyler Technologies, a Texas-based company that bills itself as the largest provider of software and technology services to the United States public sector, is battling a network intrusion that has disrupted its operations. The company declined to discuss the exact cause of the disruption, but their response so far is straight out of the playbook for responding to ransomware incidents.

Plano, Texas-based Tyler Technologies [NYSE:TYL] has some 5,300 employees and brought in revenues of more than $1 billion in 2019. It sells a broad range of services to state and local governments, including appraisal and tax software, integrated software for courts and justice agencies, enterprise financial software systems, public safety software, records/document management software solutions and transportation software solutions for schools.

Earlier today, the normal content on tylertech.com was replaced with a notice saying the site was offline. In a statement provided to KrebsOnSecurity after the markets closed central time, Tyler Tech said early this morning the company became aware that an unauthorized intruder had gained access to its phone and information technology systems.

“Upon discovery and out of an abundance of caution, we shut down points of access to external systems and immediately began investigating and remediating the problem,” Tyler’s Chief Information Officer Matt Bieri said. “We have since engaged outside IT security and forensics experts to conduct a detailed review and help us securely restore affected equipment. We are implementing enhanced monitoring systems, and we have notified law enforcement.”

“At this time and based on the evidence available to us to-date, all indications are that the impact of this incident is limited to our internal network and phone systems,” their statement continues. “We currently have no reason to believe that any client data, client servers, or hosted systems were affected.” Continue reading

Chinese Antivirus Firm Was Part of APT41 ‘Supply Chain’ Attack

September 17, 2020

The U.S. Justice Department this week indicted seven Chinese nationals for a decade-long hacking spree that targeted more than 100 high-tech and online gaming companies. The government alleges the men used malware-laced phishing emails and “supply chain” attacks to steal data from companies and their customers. One of the alleged hackers was first profiled here in 2012 as the owner of a Chinese antivirus firm.

Image: FBI

Charging documents say the seven men are part of a hacking group known variously as “APT41,” “Barium,” “Winnti,” “Wicked Panda,” and “Wicked Spider.” Once inside of a target organization, the hackers stole source code, software code signing certificates, customer account data and other information they could use or resell.

APT41’s activities span from the mid-2000s to the present day. Earlier this year, for example, the group was tied to a particularly aggressive malware campaign that exploited recent vulnerabilities in widely-used networking products, including flaws in Cisco and D-Link routers, as well as Citrix and Pulse VPN appliances. Security firm FireEye dubbed that hacking blitz “one of the broadest campaigns by a Chinese cyber espionage actor we have observed in recent years.”

The government alleges the group monetized its illicit access by deploying ransomware and “cryptojacking” tools (using compromised systems to mine cryptocurrencies like Bitcoin). In addition, the gang targeted video game companies and their customers in a bid to steal digital items of value that could be resold, such as points, powers and other items that could be used to enhance the game-playing experience.

APT41 was known to hide its malware inside fake resumes that were sent to targets. It also deployed more complex supply chain attacks, in which they would hack a software company and modify the code with malware.

“The victim software firm — unaware of the changes to its product, would subsequently distribute the modified software to its third-party customers, who were thereby defrauded into installing malicious software code on their own computers,” the indictments explain.

While the various charging documents released in this case do not mention it per se, it is clear that members of this group also favored another form of supply chain attacks — hiding their malware inside commercial tools they created and advertised as legitimate security software and PC utilities.

One of the men indicted as part of APT41 — now 35-year-old Tan DaiLin — was the subject of a 2012 KrebsOnSecurity story that sought to shed light on a Chinese antivirus product marketed as Anvisoft. At the time, the product had been “whitelisted” or marked as safe by competing, more established antivirus vendors, although the company seemed unresponsive to user complaints and to questions about its leadership and origins.

Anvisoft claimed to be based in California and Canada, but a search on the company’s brand name turned up trademark registration records that put Anvisoft in the high-tech zone of Chengdu in the Sichuan Province of China.

A review of Anvisoft’s website registration records showed the company’s domain originally was created by Tan DaiLin, an infamous Chinese hacker who went by the aliases “Wicked Rose” and “Withered Rose.” At the time of story, DaiLin was 28 years old.

That story cited a 2007 report (PDF) from iDefense, which detailed DaiLin’s role as the leader of a state-sponsored, four-man hacking team called NCPH (short for Network Crack Program Hacker). According to iDefense, in 2006 the group was responsible for crafting a rootkit that took advantage of a zero-day vulnerability in Microsoft Word, and was used in attacks on “a large DoD entity” within the USA.

“Wicked Rose and the NCPH hacking group are implicated in multiple Office based attacks over a two year period,” the iDefense report stated.

When I first scanned Anvisoft at Virustotal.com back in 2012, none of the antivirus products detected it as suspicious or malicious. But in the days that followed, several antivirus products began flagging it for bundling at least two trojan horse programs designed to steal passwords from various online gaming platforms.

Two Russians Charged in $17M Cryptocurrency Phishing Spree

September 16, 2020

U.S. authorities today announced criminal charges and financial sanctions against two Russian men accused of stealing nearly $17 million worth of virtual currencies in a series of phishing attacks throughout 2017 and 2018 that spoofed websites for some of the most popular cryptocurrency exchanges.


The Justice Department unsealed indictments against Russian nationals Danil Potekhin and Dmitirii Karasavidi, alleging the duo was responsible for a sophisticated phishing and money laundering campaign that resulted in the theft of $16.8 million in cryptocurrencies and fiat money from victims.

Separately, the U.S. Treasury Department announced economic sanctions against Potekhin and Karasavidi, effectively freezing all property and interests of these persons (subject to U.S. jurisdiction) and making it a crime to transact with them.

According to the indictments, the two men set up fake websites that spoofed login pages for the currency exchanges Binance, Gemini and Poloniex. Armed with stolen login credentials, the men allegedly stole more than $10 million from 142 Binance victims, $5.24 million from 158 Poloniex users, and $1.17 million from 42 Gemini customers.

Prosecutors say the men then laundered the stolen funds through an array of intermediary cryptocurrency accounts — including compromised and fictitiously created accounts — on the targeted cryptocurrency exchange platforms. In addition, the two are alleged to have artificially inflated the value of their ill-gotten gains by engaging in cryptocurrency price manipulation using some of the stolen funds.

For example, investigators alleged Potekhin and Karasavidi used compromised Poloniex accounts to place orders to purchase large volumes of “GAS,” the digital currency token used to pay the cost of executing transactions on the NEO blockchain — China’s first open source blockchain platform.

“Using digital crurency in one victim Poloniex account, they placed an order to purchase approximately 8,000 GAS, thereby immediately increasing the market price of GAS from approximately $18 to $2,400,” the indictment explains.

Potekhin and others then converted the artificially inflated GAS in their own fictitious Poloniex accounts into other cryptocurrencies, including Ethereum (ETH) and Bitcoin (BTC). From the complaint:

“Before the Eight Fictitious Poloniex Accounts were frozen, POTEKHIN and others transferred approximately 759 ETH to nine digital currency addresses. Through a sophisticated and layered manner, the ETH from these nine digital currency addresses was sent through multiple intermediary accounts, before ultimately being deposited into a Bitfinex account controlled by Karasavidi.”

The Treasury’s action today lists several of the cryptocurrency accounts thought to have been used by the defendants. Searching on some of those accounts at various cryptocurrency transaction tracking sites points to a number of phishing victims.

“I would like to blow your bitch ass away, if you even had the balls to show yourself,” exclaimed one victim, posting in a comment on the Etherscan lookup service. Continue reading
