U.S. Indicts 2 Top Russian Hackers, Sanctions Cryptex

By: BrianKrebs — September 26th 2024 at 14:54

The United States today unveiled sanctions and indictments against the alleged proprietor of Joker’s Stash, a now-defunct cybercrime store that peddled tens of millions of payment cards stolen in some of the largest data breaches of the past decade. The government also indicted and sanctioned a top Russian cybercriminal known as Taleon, whose cryptocurrency exchange Cryptex has evolved into one of Russia’s most active money laundering networks.

The U.S. Department of Justice (DOJ) today unsealed an indictment against a 38-year-old man from Novosibirsk, Russia for allegedly operating Joker’s Stash, an extremely successful carding shop that came online in late 2014. Joker’s sold cards stolen in a steady drip of breaches at U.S. retailers, including Saks Fifth Avenue, Lord and TaylorBebe StoresHilton HotelsJason’s DeliWhole FoodsChipotleWawaSonic Drive-In, the Hy-Vee supermarket chainBuca Di Beppo, and Dickey’s BBQ.

The government believes the brains behind Joker’s Stash is Timur Kamilevich Shakhmametov, an individual who is listed in Russian incorporation documents as the owner of Arpa Plus, a Novosibirsk company that makes mobile games.

Early in his career (circa 2000) Shakhmametov was known as “v1pee” and was the founder of the Russian hacker group nerf[.]ru, which periodically published hacking tools and exploits for software vulnerabilities.

The Russian hacker group Nerf as described in a March 2006 article in the Russian hacker magazine xakep.ru.

By 2004, v1pee had adopted the moniker “Vega” on the exclusive Russian language hacking forum Mazafaka, where this user became one of the more reliable vendors of stolen payment cards.

In the years that followed, Vega would cement his reputation as a top carder on other forums, including Verified, DirectConnection, and Carder[.]pro.

Vega also became known as someone who had the inside track on “unlimited cashouts,” a globally coordinated cybercrime scheme in which crooks hack a bank or payment card processor and use cloned cards at cash machines to rapidly withdraw millions of dollars in just a few hours.

“Hi, there is work on d+p, unlimited,” Vega wrote in a private message to another user on Verified in Dec. 2012, referring to “dumps and PINs,” the slang term for stolen debit cards with the corresponding PINs that would allow ATM withdrawals.

This batch of some five million cards put up for sale Sept. 26, 2017 on the now-defunct carding site Joker’s Stash has been tied to a breach at Sonic Drive-In.

Joker’s Stash came online in the wake of several enormous card breaches at retailers like Target and Home Depot, and the resulting glut of inventory had depressed prices for stolen cards. But Joker’s would distinguish itself by catering to high-roller customers — essentially street gangs in the United States that would purchase thousands of stolen payment cards in one go.

Faced with a buyer’s market, Joker’s Stash set themselves apart by focusing on loyalty programs, frequent buyer discounts, money-back guarantees, and just plain good customer service. Big spenders were given access to the most freshly hacked payment cards, and were offered the ability to get free replacement cards if any turned out to be duds.

Joker’s Stash also was unique because it claimed to sell only payment cards that its own hackers had stolen directly from merchants. At the time, card shops typically resold payment cards that were stolen and supplied by many third-party hackers of unknown reliability or reputation.

In January 2021, Joker’s Stash announced it was closing up shop, after European authorities seized a number of servers for the fraud store, and its proprietor came down with the Coronavirus.

A DOJ statement credits the U.S. Secret Service for leading the years-long investigations (the Service’s original mandate was not protecting the president; it was pursuing counterfeiters, and modern-day carders definitely qualify as that). Prosecutors allege Joker’s Stash earned revenues of at least $280 million, but possibly more than $1 billion (the broad range is a consequence of several variables, including the rapid fluctuation in the price of bitcoin and the stolen goods they were peddling).

TALEON

The proprietors of Joker’s Stash may have sold tens of millions of stolen payment cards, but Taleon is by far the bigger fish in this law enforcement action because his various cryptocurrency and cash exchanges have allegedly helped to move billions of dollars into and out of Russia over the past 20 years.

An indictment unsealed today names Taleon as Sergey Sergeevich Ivanov, 44, of Saint Petersburg, Russia. The government says Ivanov, who likely changed his surname from Omelnitskii at some point, laundered money for Joker’s Stash, among many other cybercrime stores.

In a statement today, the Treasury Department said Ivanov has laundered hundreds of millions of dollars’ worth of virtual currency for ransomware actors, initial access brokers, darknet marketplace vendors, and other criminal actors for approximately the last 20 years.

First appearing on Mazafaka in the early 2000s, Taleon was known on the forums as someone who could reliably move large amounts of physical cash. Sources familiar with the investigation said Taleon’s service emerged as one of the few remaining domestic cash delivery services still operating after Russia invaded Ukraine in Feb. 2022.

Taleon set up his service to facilitate transfers between Moscow, St. Petersburg and financial institutions in the West. Taleon’s private messages on some hacker forums have been leaked over the years and indexed by the cyber intelligence platform Intel 471. Those messages indicate Taleon worked on many of the same ATM cashouts as Vegas, so it’s clear the two had an established business relationship well before Joker’s Stash came into being.

Sometime around 2013, Taleon launched a partnership with a money transfer business called pm2btc[.]me. PM2BTC allowed customers to convert funds from the virtual currency Perfect Money (PM) into bitcoin, and then have the balance (minus a processing fee) available on a physical debit card that could be used at ATMs, for shopping online, or at retail stores.

A screenshot of a website reviewing PM2BTC.

The U.S. government itself set things in motion for Taleon’s nascent cryptocurrency exchange business in 2013 after the DOJ levied money laundering charges against the proprietors of Liberty Reserve, one of the largest virtual currencies in operation at the time.  Liberty Reserve was heavily used by cybercriminals of all stripes. The government said the service had more than a million users worldwide, and laundered in excess of $6 billion in suspected criminal proceeds.

In the days following the takedown of Liberty Reserve, KrebsOnSecurity ran a story that examined discussions across multiple top Russian cybercrime forums about where crooks could feel safe parking their stolen funds. The answer involved Bitcoin, but also Taleon’s new service.

UAPS

Part of the appeal of Taleon’s exchange was that it gave its vetted customers an “application programming interface” or API that made it simple for dodgy online shops selling stolen goods and cybercrime services to accept cryptocurrency deposits from their customers, and to manage payouts to any suppliers and affiliates.

This API is synonymous with a service Taleon and friends operate in the background called UAPS, short for “Universal Anonymous Payment System.” UAPS has gone by several other names including “Pinpays,” and in October 2014 it landed Joker’s Stash as its first big client.

A source with knowledge of the investigation told KrebsOnSecurity that Taleon is a pilot who owns and flies around in his own helicopter.

Ivanov appears to have little to no social media presence, but the 40-year-old woman he lives with in St. Petersburg does, and she has a photo on her Vktontake page that shows the two of them in 2019 flying over Lake Ladoga, a large body of water directly north of St. Petersburg.

BRIANS CLUB

In late 2015, a major competitor to Joker’s Stash emerged using UAPS for its back-end payments: BriansClub. BriansClub sullies this author’s name, photos and reputation to peddle millions of credit and debit cards stolen from merchants in the United States and around the world.

An ad for BriansClub has been using my name and likeness for years to peddle millions of stolen credit cards.

In 2019, someone hacked BriansClub and relieved the fraud shop of more than 26 million stolen payment cards — an estimated one-third of the 87 million payment card accounts that were on sale across all underground shops at that time. An anonymous source shared that card data with KrebsOnSecurity, which ultimately shared it with a consortium of financial institutions that issued most of the cards.

After that incident, the administrator of BriansClub changed the site’s login page so that it featured a copy of my phone bill, Social Security card, and a link to my full credit report [to this day, random cybercriminals confuse Yours Truly with the proprietor of BriansClub].

Alex Holden is founder of the Milwaukee-based cybersecurity firm Hold Security. Holden has long maintained visibility into cryptocurrency transactions made by BriansClub.

Holden said those records show BriansClub sells tens of thousands of dollars worth of stolen credit cards every day, and that in the last two years alone the BriansClub administrator has removed more than $242 million worth of cryptocurrency revenue from the UAPS platform.

Passive domain name system (DNS) records show that in its early days BriansClub shared a server in Lithuania along with just a handful of other domains, including secure.pinpays[.]com, the crime forum Verified, and a slew of carding shops operating under the banner Rescator.

As KrebsOnSecurity detailed in December 2023, the Rescator shops were directly involved in some of the largest payment card breaches of the past decade. Those include the 2013 breach at Target and the 2014 breach at Home Depot, intrusions that exposed more than 100 million payment card records.

CRYPTEX

In early 2018, Taleon and the proprietors of UAPS launched a cryptocurrency exchange called Cryptex[.]net that has emerged as a major mover of ill-gotten crypto coins.

Taleon reminds UAPS customers they will enjoy 0% commission and no “know your customer” (KYC) requirements “on our exchange Cryptex.”

Cryptex has been associated with quite a few ransomware transactions, including the largest known ransomware payment to date. In February 2024, a Fortune 50 ransomware victim paid a record $75 million ransom to a Russian cybercrime group that calls themselves the Dark Angels. A source with knowledge of the investigation said an analysis of that payment shows roughly half of it was processed through Cryptex.

That source provided a screen shot of Cryptex’s sending and receiving exposure as viewed by Chainalysis, a company the U.S. government and many cryptocurrency exchanges rely on to flag transactions associated with suspected money laundering, ransomware payouts, or facilitating payments for darknet websites.

Chainalysis finds that Cryptex has received more than $1.6 billion since its inception, and that this amount is roughly equal to its sending exposure (although the total number of outflows is nearly half of the inflows).

The graphic indicates a great deal of money flowing into Cryptex — roughly a quarter of it — is coming from bitcoin ATMs around the world. Experts say most of those ATM inflows to Cryptex are bitcoin ATM cash deposits from customers of carding websites like BriansClub and Jokers Stash.

The indictments released today do not definitively connect Taleon to Cryptex. However, PM2BTC (which teamed up with Taleon to launch UAPS and Pinpays) and Cryptex have now been sanctioned by the U.S. Department of the Treasury.

Treasury’s Financial Crimes Enforcement Network (FinCEN) levied sanctions today against PM2BTC under a powerful new “Section 9714” authority included in the Combating Russian Money Laundering Act, changes enacted in 2022 to make it easier to target financial entities involved in laundering money for Russia.

Treasury first used this authority last year against Bitzlato, a cryptocurrency exchange operating in Russia that became a money laundering conduit for ransomware attackers and dark market dealers.

THE LAUNDROMAT

An investigation into the corporate entities behind UAPS and Cryptex reveals an organization incorporated in 2012 in Scotland called Orbest Investments LP. Records from the United Kingdom’s business registry show the owners of Orbest Investments are two entities: CS Proxy Solutions CY, and RM Everton Ltd.

Public business records further reveal that CS Proxy Solutions and RM Everton are co-owners of Progate Solutions, a holding company that featured prominently in a June 2017 report from Bellingcat and Transparency International (PDF) on money laundering networks tied to the Kremlin.

“Law enforcement agencies believe that the total amount laundered through this process could be as high as US$80 billion,” the joint report reads. “Although it is not clear where all of this money came from, investigators claim it includes significant amounts of money that were diverted from the Russian treasury and state contracts.”

Their story built on reporting published earlier that year by the Organized Crime and Corruption Project (OCCRP) and Novaya Gazeta, which found that at least US$20.8 billion was secretly moved out of Russia between 2010 and 2014 through a vast money laundering machine comprising over 5,000 legal entities known as “The Laundromat.”

“Using company records, reporters tracked the names of some clients after executives refused to give them out,” the OCCRP report explains. “They found the heavy users of the scheme were rich and powerful Russians who had made their fortunes from dealing with the Russian state.”

Rich Sanders is a blockchain analyst and investigator who advises the law enforcement and intelligence community. Sanders just returned from a three-week sojourn through Ukraine, traveling with Ukrainian soldiers while mapping out dodgy Russian crypto exchanges that are laundering money for narcotics networks operating in the region. Sanders said today’s sanctions by the Treasury Department will likely have an immediate impact on Cryptex and its customers.

“Whenever an entity is sanctioned, the implications on-chain are immense,” Sanders told KrebsOnSecurity. “Regardless of whether an exchange is actually compliant or just virtue signals it, it is the case across the board that exchanges will pay attention to these sanctions.”

“This action shows these payment processors for illicit platforms will get attention eventually,” Sanders continued. “Even if it took way too long in this case, Cryptex knew the majority of their volume was problematic, knew why it was problematic, and did it anyway. And this should be a wake up call for other exchanges that know full well that most of their volume is problematic.”

The U.S. Department of State is offering a reward of up to $10 million each for information leading to the arrests and/or convictions of Shakhmametov and Ivanov. The State announcement says separate rewards of up to $1 million each are being offered for information leading to the identification of other leaders of the Joker’s Stash criminal marketplace (other than Shakhmametov), as well as the identification of other key leaders of the UAPS, PM2BTC, and PinPays transnational criminal groups (other than Ivanov).

Local Networks Go Global When Domain Names Collide

By: BrianKrebs — August 23rd 2024 at 14:12

The proliferation of new top-level domains (TLDs) has exacerbated a well-known security weakness: Many organizations set up their internal Microsoft authentication systems years ago using domain names in TLDs that didn’t exist at the time. Meaning, they are continuously sending their Windows usernames and passwords to domain names they do not control and which are freely available for anyone to register. Here’s a look at one security researcher’s efforts to map and shrink the size of this insidious problem.

At issue is a well-known security and privacy threat called “namespace collision,” a situation where domain names intended to be used exclusively on an internal company network end up overlapping with domains that can resolve normally on the open Internet.

Windows computers on a private corporate network validate other things on that network using a Microsoft innovation called Active Directory, which is the umbrella term for a broad range of identity-related services in Windows environments. A core part of the way these things find each other involves a Windows feature called “DNS name devolution,” a kind of network shorthand that makes it easier to find other computers or servers without having to specify a full, legitimate domain name for those resources.

Consider the hypothetical private network internalnetwork.example.com: When an employee on this network wishes to access a shared drive called “drive1,” there’s no need to type “drive1.internalnetwork.example.com” into Windows Explorer; entering “\\drive1\” alone will suffice, and Windows takes care of the rest.

But problems can arise when an organization has built their Active Directory network on top of a domain they don’t own or control. While that may sound like a bonkers way to design a corporate authentication system, keep in mind that many organizations built their networks long before the introduction of hundreds of new top-level domains (TLDs), like .network, .inc, and .llc.

For example, a company in 2005 builds their Microsoft Active Directory service around the domain company.llc, perhaps reasoning that since .llc wasn’t even a routable TLD, the domain would simply fail to resolve if the organization’s Windows computers were ever used outside of its local network.

Alas, in 2018, the .llc TLD was born and began selling domains. From then on, anyone who registered company.llc would be able to passively intercept that organization’s Microsoft Windows credentials, or actively modify those connections in some way — such as redirecting them somewhere malicious.

Philippe Caturegli, founder of the security consultancy Seralys, is one of several researchers seeking to chart the size of the namespace collision problem. As a professional penetration tester, Caturegli has long exploited these collisions to attack specific targets that were paying to have their cyber defenses probed. But over the past year, Caturegli has been gradually mapping this vulnerability across the Internet by looking for clues that appear in self-signed security certificates (e.g. SSL/TLS certs).

Caturegli has been scanning the open Internet for self-signed certificates referencing domains in a variety of TLDs likely to appeal to businesses, including .ad, .associates, .center, .cloud, .consulting, .dev, .digital, .domains, .email, .global, .gmbh, .group, .holdings, .host, .inc, .institute, .international, .it, .llc, .ltd, .management, .ms, .name, .network, .security, .services, .site, .srl, .support, .systems, .tech, .university, .win and .zone, among others.

Seralys found certificates referencing more than 9,000 distinct domains across those TLDs. Their analysis determined many TLDs had far more exposed domains than others, and that about 20 percent of the domains they found ending .ad, .cloud and .group remain unregistered.

“The scale of the issue seems bigger than I initially anticipated,” Caturegli said in an interview with KrebsOnSecurity. “And while doing my research, I have also identified government entities (foreign and domestic), critical infrastructures, etc. that have such misconfigured assets.”

REAL-TIME CRIME

Some of the above-listed TLDs are not new and correspond to country-code TLDs, like .it for Italy, and .ad, the country-code TLD for the tiny nation of Andorra. Caturegli said many organizations no doubt viewed a domain ending in .ad as a convenient shorthand for an internal Active Directory setup, while being unaware or unworried that someone could actually register such a domain and intercept all of their Windows credentials and any unencrypted traffic.

When Caturegli discovered an encryption certificate being actively used for the domain memrtcc.ad, the domain was still available for registration. He then learned the .ad registry requires prospective customers to show a valid trademark for a domain before it can be registered.

Undeterred, Caturegli found a domain registrar that would sell him the domain for $160, and handle the trademark registration for another $500 (on subsequent .ad registrations, he located a company in Andorra that could process the trademark application for half that amount).

Caturegli said that immediately after setting up a DNS server for memrtcc.ad, he began receiving a flood of communications from hundreds of Microsoft Windows computers trying to authenticate to the domain. Each request contained a username and a hashed Windows password, and upon searching the usernames online Caturegli concluded they all belonged to police officers in Memphis, Tenn.

“It looks like all of the police cars there have a laptop in the cars, and they’re all attached to this memrtcc.ad domain that I now own,” Caturegli said, noting wryly that “memrtcc” stands for “Memphis Real-Time Crime Center.”

Caturegli said setting up an email server record for memrtcc.ad caused him to begin receiving automated messages from the police department’s IT help desk, including trouble tickets regarding the city’s Okta authentication system.

Mike Barlow, information security manager for the City of Memphis, confirmed the Memphis Police’s systems were sharing their Microsoft Windows credentials with the domain, and that the city was working with Caturegli to have the domain transferred to them.

“We are working with the Memphis Police Department to at least somewhat mitigate the issue in the meantime,” Barlow said.

Domain administrators have long been encouraged to use .local for internal domain names, because this TLD is reserved for use by local networks and cannot be routed over the open Internet. However, Caturegli said many organizations seem to have missed that memo and gotten things backwards — setting up their internal Active Directory structure around the perfectly routable domain local.ad.

Caturegli said he knows this because he “defensively” registered local.ad, which he said is currently used by multiple large organizations for Active Directory setups — including a European mobile phone provider, and the City of Newcastle in the United Kingdom.

ONE WPAD TO RULE THEM ALL

Caturegli said he has now defensively registered a number of domains ending in .ad, such as internal.ad and schema.ad. But perhaps the most dangerous domain in his stable is wpad.ad. WPAD stands for Web Proxy Auto-Discovery Protocol, which is an ancient, on-by-default feature built into every version of Microsoft Windows that was designed to make it simpler for Windows computers to automatically find and download any proxy settings required by the local network.

Trouble is, any organization that chose a .ad domain they don’t own for their Active Directory setup will have a whole bunch of Microsoft systems constantly trying to reach out to wpad.ad if those machines have proxy automated detection enabled.

Security researchers have been beating up on WPAD for more than two decades now, warning time and again how it can be abused for nefarious ends. At this year’s DEF CON security conference in Las Vegas, for example, a researcher showed what happened after they registered the domain wpad.dk: Immediately after switching on the domain, they received a flood of WPAD requests from Microsoft Windows systems in Denmark that had namespace collisions in their Active Directory environments.

Image: Defcon.org.

For his part, Caturegli set up a server on wpad.ad to resolve and record the Internet address of any Windows systems trying to reach Microsoft Sharepoint servers, and saw that over one week it received more than 140,000 hits from hosts around the world attempting to connect.

The fundamental problem with WPAD is the same with Active Directory: Both are technologies originally designed to be used in closed, static, trusted office environments, and neither was built with today’s mobile devices or workforce in mind.

Probably one big reason organizations with potential namespace collision problems don’t fix them is that rebuilding one’s Active Directory infrastructure around a new domain name can be incredibly disruptive, costly, and risky, while the potential threat is considered comparatively low.

But Caturegli said ransomware gangs and other cybercrime groups could siphon huge volumes of Microsoft Windows credentials from quite a few companies with just a small up-front investment.

“It’s an easy way to gain that initial access without even having to launch an actual attack,” he said. “You just wait for the misconfigured workstation to connect to you and send you their credentials.”

If we ever learn that cybercrime groups are using namespace collisions to launch ransomware attacks, nobody can say they weren’t warned. Mike O’Connor, an early domain name investor who registered a number of choice domains such as bar.com, place.com and television.com, warned loudly and often back in 2013 that then-pending plans to add more than 1,000 new TLDs would massively expand the number of namespace collisions.

Mr. O’Connor’s most famous domain is corp.com, because for several decades he watched in horror as hundreds of thousands of Microsoft PCs continuously blasted his domain with credentials from organizations that had set up their Active Directory environment around the domain corp.com.

It turned out that Microsoft had actually used corp.com as an example of how one might set up Active Directory in some editions of Windows NT. Worse, some of the traffic going to corp.com was coming from Microsoft’s internal networks, indicating some part of Microsoft’s own internal infrastructure was misconfigured. When O’Connor said he was ready to sell corp.com to the highest bidder in 2020, Microsoft agreed to buy the domain for an undisclosed amount.

“I kind of imagine this problem to be something like a town [that] knowingly built a water supply out of lead pipes, or vendors of those projects who knew but didn’t tell their customers,” O’Connor told KrebsOnSecurity. “This is not an inadvertent thing like Y2K where everybody was surprised by what happened. People knew and didn’t care.”

The Stark Truth Behind the Resurgence of Russia’s Fin7

By: BrianKrebs — July 10th 2024 at 16:22

The Russia-based cybercrime group dubbed “Fin7,” known for phishing and malware attacks that have cost victim organizations an estimated $3 billion in losses since 2013, was declared dead last year by U.S. authorities. But experts say Fin7 has roared back to life in 2024 — setting up thousands of websites mimicking a range of media and technology companies — with the help of Stark Industries Solutions, a sprawling hosting provider that is a persistent source of cyberattacks against enemies of Russia.

In May 2023, the U.S. attorney for Washington state declared “Fin7 is an entity no more,” after prosecutors secured convictions and prison sentences against three men found to be high-level Fin7 hackers or managers. This was a bold declaration against a group that the U.S. Department of Justice described as a criminal enterprise with more than 70 people organized into distinct business units and teams.

The first signs of Fin7’s revival came in April 2024, when Blackberry wrote about an intrusion at a large automotive firm that began with malware served by a typosquatting attack targeting people searching for a popular free network scanning tool.

Now, researchers at security firm Silent Push say they have devised a way to map out Fin7’s rapidly regrowing cybercrime infrastructure, which includes more than 4,000 hosts that employ a range of exploits, from typosquatting and booby-trapped ads to malicious browser extensions and spearphishing domains.

Silent Push said it found Fin7 domains targeting or spoofing brands including American Express, Affinity Energy, Airtable, Alliant, Android Developer, Asana, Bitwarden, Bloomberg, Cisco (Webex), CNN, Costco, Dropbox, Grammarly, Google, Goto.com, Harvard, Lexis Nexis, Meta, Microsoft 365, Midjourney, Netflix, Paycor, Quickbooks, Quicken, Reuters, Regions Bank Onepass, RuPay, SAP (Ariba), Trezor, Twitter/X, Wall Street Journal, Westlaw, and Zoom, among others.

Zach Edwards, senior threat analyst at Silent Push, said many of the Fin7 domains are innocuous-looking websites for generic businesses that sometimes include text from default website templates (the content on these sites often has nothing to do with the entity’s stated business or mission).

Edwards said Fin7 does this to “age” the domains and to give them a positive or at least benign reputation before they’re eventually converted for use in hosting brand-specific phishing pages.

“It took them six to nine months to ramp up, but ever since January of this year they have been humming, building a giant phishing infrastructure and aging domains,” Edwards said of the cybercrime group.

In typosquatting attacks, Fin7 registers domains that are similar to those for popular free software tools. Those look-alike domains are then advertised on Google so that sponsored links to them show up prominently in search results, which is usually above the legitimate source of the software in question.

A malicious site spoofing FreeCAD showed up prominently as a sponsored result in Google search results earlier this year.

According to Silent Push, the software currently being targeted by Fin7 includes 7-zip, PuTTY, ProtectedPDFViewer, AIMP, Notepad++, Advanced IP Scanner, AnyDesk, pgAdmin, AutoDesk, Bitwarden, Rest Proxy, Python, Sublime Text, and Node.js.

In May 2024, security firm eSentire warned that Fin7 was spotted using sponsored Google ads to serve pop-ups prompting people to download phony browser extensions that install malware. Malwarebytes blogged about a similar campaign in April, but did not attribute the activity to any particular group.

A pop-up at a Thomson Reuters typosquatting domain telling visitors they need to install a browser extension to view the news content.

Edwards said Silent Push discovered the new Fin7 domains after a hearing from an organization that was targeted by Fin7 in years past and suspected the group was once again active. Searching for hosts that matched Fin7’s known profile revealed just one active site. But Edwards said that one site pointed to many other Fin7 properties at Stark Industries Solutions, a large hosting provider that materialized just two weeks before Russia invaded Ukraine.

As KrebsOnSecurity wrote in May, Stark Industries Solutions is being used as a staging ground for wave after wave of cyberattacks against Ukraine that have been tied to Russian military and intelligence agencies.

“FIN7 rents a large amount of dedicated IP on Stark Industries,” Edwards said. “Our analysts have discovered numerous Stark Industries IPs that are solely dedicated to hosting FIN7 infrastructure.”

Fin7 once famously operated behind fake cybersecurity companies — with names like Combi Security and Bastion Secure — which they used for hiring security experts to aid in ransomware attacks. One of the new Fin7 domains identified by Silent Push is cybercloudsec[.]com, which promises to “grow your business with our IT, cyber security and cloud solutions.”

The fake Fin7 security firm Cybercloudsec.

Like other phishing groups, Fin7 seizes on current events, and at the moment it is targeting tourists visiting France for the Summer Olympics later this month. Among the new Fin7 domains Silent Push found are several sites phishing people seeking tickets at the Louvre.

“We believe this research makes it clear that Fin7 is back and scaling up quickly,” Edwards said. “It’s our hope that the law enforcement community takes notice of this and puts Fin7 back on their radar for additional enforcement actions, and that quite a few of our competitors will be able to take this pool and expand into all or a good chunk of their infrastructure.”

Is Your Computer Part of ‘The Largest Botnet Ever?’

By: BrianKrebs — May 29th 2024 at 19:21

The U.S. Department of Justice (DOJ) today said they arrested the alleged operator of 911 S5, a ten-year-old online anonymity service that was powered by what the director of the FBI called “likely the world’s largest botnet ever.” The arrest coincided with the seizure of the 911 S5 website and supporting infrastructure, which the government says turned computers running various “free VPN” products into Internet traffic relays that facilitated billions of dollars in online fraud and cybercrime.

The Cloud Router homepage, which was seized by the FBI this past weekend. Cloud Router was previously called 911 S5.

On May 24, authorities in Singapore arrested the alleged creator and operator of 911 S5, a 35-year-old Chinese national named YunHe Wang. In a statement on his arrest today, the DOJ said 911 S5 enabled cybercriminals to bypass financial fraud detection systems and steal billions of dollars from financial institutions, credit card issuers, and federal lending programs.

For example, the government estimates that 560,000 fraudulent unemployment insurance claims originated from compromised Internet addresses, resulting in a confirmed fraudulent loss exceeding $5.9 billion.

“Additionally, in evaluating suspected fraud loss to the Economic Injury Disaster Loan (EIDL) program, the United States estimates that more than 47,000 EIDL applications originated from IP addresses compromised by 911 S5,” the DOJ wrote. “Millions of dollars more were similarly identified by financial institutions in the United States as loss originating from IP addresses compromised by 911 S5.”

From 2015 to July 2022, 911 S5 sold access to hundreds of thousands of Microsoft Windows computers daily, as “proxies” that allowed customers to route their Internet traffic through PCs in virtually any country or city around the globe — but predominantly in the United States.

911 S5 built its proxy network mainly by offering “free” virtual private networking (VPN) services. 911’s VPN performed largely as advertised for the user — allowing them to surf the web anonymously — but it also quietly turned the user’s computer into a traffic relay for paying 911 S5 customers.

911 S5’s reliability and extremely low prices quickly made it one of the most popular services among denizens of the cybercrime underground, and the service became almost shorthand for connecting to that “last mile” of cybercrime. Namely, the ability to route one’s malicious traffic through a computer that is geographically close to the consumer whose stolen credit card is about to be used, or whose bank account is about to be emptied.

The prices page for 911 S5, circa July 2022. $28 would let users cycle through 150 proxies on this popular service.

KrebsOnSecurity first identified Mr. Wang as the proprietor of the popular service in a deep dive on 911 S5 published in July 2022. That story showed that 911 S5 had a history of paying people to install its software by secretly bundling it with other software — including fake security updates for common programs like Flash Player, and “cracked” or pirated commercial software distributed on file-sharing networks.

Ten days later, 911 S5 closed up shop, claiming it had been hacked. But experts soon tracked the reemergence of the proxy network by another name: Cloud Router.

The announcement of Wang’s arrest came less than 24 hours after the U.S. Department of the Treasury sanctioned Wang and two associates, as well as several companies the men allegedly used to launder the nearly $100 million in proceeds from 911 S5 and Cloud Router customers.

Cloud Router’s homepage now features a notice saying the domain has been seized by the U.S. government. In addition, the DOJ says it worked with authorities in Singapore, Thailand and Germany to search residences tied to the defendant, and seized approximately $30 million in assets.

The Cloud Router homepage now features a seizure notice from the FBI in multiple languages.

Those assets included a 2022 Ferrari F8 Spider S-A, a BMW i8, a BMW X7 M50d, a Rolls Royce, more than a dozen domestic and international bank accounts, over two dozen cryptocurrency wallets, several luxury wristwatches, and 21 residential or investment properties.

The government says Wang is charged with conspiracy to commit computer fraud, substantive computer fraud, conspiracy to commit wire fraud, and conspiracy to commit money laundering. If convicted on all counts, he faces a maximum penalty of 65 years in prison.

Brett Leatherman, deputy assistant director of the FBI’s Cyber Division, said the DOJ is working with the Singaporean government on extraditing Wang to face charges in the United States.

Leatherman encouraged Internet users to visit a new FBI webpage that can help people determine whether their computers may be part of the 911 S5 botnet, which the government says spanned more than 19 million individual computers in at least 190 countries.

Leatherman said 911 S5 and Cloud Router used several “free VPN” brands to lure consumers into installing the proxy service, including MaskVPN, DewVPN, PaladinVPN, Proxygate, Shield VPN, and ShineVPN.

“American citizens who didn’t know that their IP space was being utilized to attack US businesses or defraud the U.S. government, they were unaware,” Leatherman said. “But these kind of operations breed that awareness.”

Treasury Sanctions Creators of 911 S5 Proxy Botnet

By: BrianKrebs — May 28th 2024 at 20:38

The U.S. Department of the Treasury today unveiled sanctions against three Chinese nationals for allegedly operating 911 S5, an online anonymity service that for many years was the easiest and cheapest way to route one’s Web traffic through malware-infected computers around the globe. KrebsOnSecurity identified one of the three men in a July 2022 investigation into 911 S5, which was massively hacked and then closed ten days later.

The 911 S5 botnet-powered proxy service, circa July 2022.

From 2015 to July 2022, 911 S5 sold access to hundreds of thousands of Microsoft Windows computers daily, as “proxies” that allowed customers to route their Internet traffic through PCs in virtually any country or city around the globe — but predominantly in the United States.

911 built its proxy network mainly by offering “free” virtual private networking (VPN) services. 911’s VPN performed largely as advertised for the user — allowing them to surf the web anonymously — but it also quietly turned the user’s computer into a traffic relay for paying 911 S5 customers.

911 S5’s reliability and extremely low prices quickly made it one of the most popular services among denizens of the cybercrime underground, and the service became almost shorthand for connecting to that “last mile” of cybercrime. Namely, the ability to route one’s malicious traffic through a computer that is geographically close to the consumer whose stolen credit card is about to be used, or whose bank account is about to be emptied.

In July 2022, KrebsOnSecurity published a deep dive into 911 S5, which found the people operating this business had a history of encouraging the installation of their proxy malware by any means available. That included paying affiliates to distribute their proxy software by secretly bundling it with other software.

A cached copy of flashupdate dot net, a pay-per-install affiliate program that incentivized the silent installation of 911’s proxy software.

That story named Yunhe Wang from Beijing as the apparent owner or manager of the 911 S5 proxy service. In today’s Treasury action, Mr. Wang was named as the primary administrator of the botnet that powered 911 S5.

“A review of records from network infrastructure service providers known to be utilized by 911 S5 and two Virtual Private Networks (VPNs) specific to the botnet operation (MaskVPN and DewVPN) showed Yunhe Wang as the registered subscriber to those providers’ services,” reads the Treasury announcement.

Update, May 29, 12:26 p.m. ET: The U.S. Department of Justice (DOJ) just announced they have arrested Wang in connection with the 911 S5 botnet. The DOJ says 911 S5 customers have stolen billions of dollars from financial institutions, credit card issuers, and federal lending programs.

“911 S5 customers allegedly targeted certain pandemic relief programs,” a DOJ statement on the arrest reads. “For example, the United States estimates that 560,000 fraudulent unemployment insurance claims originated from compromised IP addresses, resulting in a confirmed fraudulent loss exceeding $5.9 billion. Additionally, in evaluating suspected fraud loss to the Economic Injury Disaster Loan (EIDL) program, the United States estimates that more than 47,000 EIDL applications originated from IP addresses compromised by 911 S5. Millions of dollars more were similarly identified by financial institutions in the United States as loss originating from IP addresses compromised by 911 S5.”

The sanctions say Jingping Liu was Yunhe Wang’s co-conspirator in the laundering of criminally derived proceeds generated from 911 S5, mainly virtual currency. The government alleges the virtual currencies paid by 911 S5 users were converted into U.S. dollars using over-the-counter vendors who wired and deposited funds into bank accounts held by Liu.

“Jingping Liu assisted Yunhe Wang by laundering criminally derived proceeds through bank accounts held in her name that were then utilized to purchase luxury real estate properties for Yunhe Wang,” the document continues. “These individuals leveraged their malicious botnet technology to compromise personal devices, enabling cybercriminals to fraudulently secure economic assistance intended for those in need and to terrorize our citizens with bomb threats.”

The third man sanctioned is Yanni Zheng, a Chinese national the U.S. Treasury says acted as an attorney for Wang and his firm — Spicy Code Company Limited — and helped to launder proceeds from the business into real estate holdings. Spicy Code Company was also sanctioned, as well as Wang-controlled properties Tulip Biz Pattaya Group Company Limited, and Lily Suites Company Limited.

Ten days after the July 2022 story here on 911 S5, the proxy network abruptly closed up shop, citing a data breach that destroyed key components of its business operations.

In the months that followed, however, 911 S5 would resurrect itself under a different name: Cloud Router. That’s according to spur.us, a U.S.-based startup that tracks proxy and VPN services. In February 2024, Spur published research showing the Cloud Router operators reused many of the same components from 911 S5, making it relatively simple to draw a connection between the two.

The Cloud Router homepage, which according to Spur has been unreachable since this past weekend.

Spur found that Cloud Router was being powered by a new VPN service called PaladinVPN, which made it much more explicit to users that their Internet connections were going to be used to relay traffic for others. At the time, Spur found Cloud Router had more than 140,000 Internet addresses for rent.

Spur co-founder Riley Kilmer said Cloud Router appears to have suspended or ceased operations sometime this past weekend. Kilmer said the number of proxies advertised by the service had been trending downwards quite recently before the website suddenly went offline.

Cloud Router’s homepage is currently populated by a message from Cloudflare saying the site’s domain name servers are pointing to a “prohibited IP.”

Stark Industries Solutions: An Iron Hammer in the Cloud

By: BrianKrebs — May 23rd 2024 at 23:32

The homepage of Stark Industries Solutions.

Two weeks before Russia invaded Ukraine in February 2022, a large, mysterious new Internet hosting firm called Stark Industries Solutions materialized and quickly became the epicenter of massive distributed denial-of-service (DDoS) attacks on government and commercial targets in Ukraine and Europe. An investigation into Stark Industries reveals it is being used as a global proxy network that conceals the true source of cyberattacks and disinformation campaigns against enemies of Russia.

At least a dozen patriotic Russian hacking groups have been launching DDoS attacks since the start of the war at a variety of targets seen as opposed to Moscow. But by all accounts, few attacks from those gangs have come close to the amount of firepower wielded by a pro-Russia group calling itself “NoName057(16).”

This graphic comes from a recent report from NETSCOUT about DDoS attacks from Russian hacktivist groups.

As detailed by researchers at Radware, NoName has effectively gamified DDoS attacks, recruiting hacktivists via its Telegram channel and offering to pay people who agree to install a piece of software called DDoSia. That program allows NoName to commandeer the host computers and their Internet connections in coordinated DDoS campaigns, and DDoSia users with the most attacks can win cash prizes.

A report from the security firm Team Cymru found the DDoS attack infrastructure used in NoName campaigns is assigned to two interlinked hosting providers: MIRhosting and Stark Industries. MIRhosting is a hosting provider founded in The Netherlands in 2004. But Stark Industries Solutions Ltd was incorporated on February 10, 2022, just two weeks before the Russian invasion of Ukraine.

PROXY WARS

Security experts say that not long after the war started, Stark began hosting dozens of proxy services and free virtual private networking (VPN) services, which are designed to help users shield their Internet usage and location from prying eyes.

Proxy providers allow users to route their Internet and Web browsing traffic through someone else’s computer. From a website’s perspective, the traffic from a proxy network user appears to originate from the rented IP address, not from the proxy service customer.

These services can be used in a legitimate manner for several business purposes — such as price comparisons or sales intelligence — but they are also massively abused for hiding cybercrime activity because they can make it difficult to trace malicious traffic to its original source.

What’s more, many proxy services do not disclose how they obtain access to the proxies they are renting out, and in many cases the access is obtained through the dissemination of malicious software that turns the infected system into a traffic relay — usually unbeknownst to the legitimate owner of the Internet connection. Other proxy services will allow users to make money by renting out their Internet connection to anyone.

Spur.us is a company that tracks VPNs and proxy services worldwide. Spur finds that Stark Industries (AS44477) currently is home to at least 74 VPN services, and 40 different proxy services. As we’ll see in the final section of this story, just one of those proxy networks has over a million Internet addresses available for rent across the globe.

Raymond Dijkxhoorn operates a hosting firm in The Netherlands called Prolocation. He also co-runs SURBL, an anti-abuse service that flags domains and Internet address ranges that are strongly associated with spam and cybercrime activity, including DDoS.

Dijkxhoorn said last year SURBL heard from multiple people who said they operated VPN services whose web resources were included in SURBL’s block lists.

“We had people doing delistings at SURBL for domain names that were suspended by the registrars,” Dijkhoorn told KrebsOnSecurity. “And at least two of them explained that Stark offered them free VPN services that they were reselling.”

Dijkxhoorn added that Stark Industries also sponsored activist groups from Ukraine.

“How valuable would it be for Russia to know the real IPs from Ukraine’s tech warriors?” he observed.

CLOUDY WITH A CHANCE OF BULLETS

Richard Hummel is threat intelligence lead at NETSCOUT. Hummel said when he considers the worst of all the hosting providers out there today, Stark Industries is consistently near or at the top of that list.

“The reason is we’ve had at least a dozen service providers come to us saying, ‘There’s this network out there inundating us with traffic,'” Hummel said. “And it wasn’t even DDoS attacks. [The systems] on Stark were just scanning these providers so fast it was crashing some of their services.”

Hummel said NoName will typically launch their attacks using a mix of resources rented from major, legitimate cloud services, and those from so-called “bulletproof” hosting providers like Stark. Bulletproof providers are so named when they earn or cultivate a reputation for ignoring any abuse complaints or police reports about activity on their networks.

Combining bulletproof providers with legitimate cloud hosting, Hummel said, likely makes NoName’s DDoS campaigns more resilient because many network operators will hesitate to be too aggressive in blocking Internet addresses associated with the major cloud services.

“What we typically see here is a distribution of cloud hosting providers and bulletproof hosting providers in DDoS attacks,” he said. “They’re using public cloud hosting providers because a lot of times that’s your first layer of network defense, and because [many companies are wary of] over-blocking access to legitimate cloud resources.”

But even if the cloud provider detects abuse coming from the customer, the provider is probably not going to shut the customer down immediately, Hummel said.

“There is usually a grace period, and even if that’s only an hour or two, you can still launch a large number of attacks in that time,” he said. “And then they just keep coming back and opening new cloud accounts.”

MERCENARIES TEAM

Stark Industries is incorporated at a mail drop address in the United Kingdom. UK business records list an Ivan Vladimirovich Neculiti as the company’s secretary. Mr. Neculiti also is named as the CEO and founder of PQ Hosting Plus S.R.L. (aka Perfect Quality Hosting), a Moldovan company formed in 2019 that lists the same UK mail drop address as Stark Industries.

Ivan Neculiti, as pictured on LinkedIn.

Reached via LinkedIn, Mr. Neculiti said PQ Hosting established Stark Industries as a “white label” of its brand so that “resellers could distribute our services using our IP addresses and their clients would not have any affairs with PQ Hosting.”

“PQ Hosting is a company with over 1,000+ of [our] own physical servers in 38 countries and we have over 100,000 clients,” he said. “Though we are not as large as Hetzner, Amazon and OVH, nevertheless we are a fast growing company that provides services to tens of thousands of private customers and legal entities.”

Asked about the constant stream of DDoS attacks whose origins have traced back to Stark Industries over the past two years, Neculiti maintained Stark hasn’t received any official abuse reports about attacks coming from its networks.

“It was probably some kind of clever attack that we did not see, I do not rule out this fact, because we have a very large number of clients and our Internet channels are quite large,” he said. “But, in this situation, unfortunately, no one contacted us to report that there was an attack from our addresses; if someone had contacted us, we would have definitely blocked the network data.”

DomainTools.com finds Ivan V. Neculiti was the owner of war[.]md, a website launched in 2008 that chronicled the history of a 1990 armed conflict in Moldova known as the Transnistria War and the Moldo-Russian war.

An ad for war.md, circa 2009.

Transnistria is a breakaway pro-Russian region that declared itself a state in 1990, although it is not internationally recognized. The copyright on that website credits the “MercenarieS TeaM,” which was at one time a Moldovan IT firm. Mr. Neculiti confirmed personally registering this domain.

DON CHICHO & DFYZ

The data breach tracking service Constella Intelligence reports that an Ivan V. Neculiti registered multiple online accounts under the email address dfyz_bk@bk.ru. Cyber intelligence firm Intel 471 shows this email address is tied to the username “dfyz” on more than a half-dozen Russian language cybercrime forums since 2008. The user dfyz on Searchengines[.]ru in 2008 asked other forum members to review war.md, and said they were part of the MercenarieS TeaM.

Back then, dfyz was selling “bulletproof servers for any purpose,” meaning the hosting company would willfully ignore abuse complaints or police inquiries about the activity of its customers.

DomainTools reports there are at least 33 domain names registered to dfyz_bk@bk.ru. Several of these domains have Ivan Neculiti in their registration records, including tracker-free[.]cn, which was registered to an Ivan Neculiti at dfyz_bk@bk.ru and referenced the MercenarieS TeaM in its original registration records.

Dfyz also used the nickname DonChicho, who likewise sold bulletproof hosting services and access to hacked Internet servers. In 2014, a prominent member of the Russian language cybercrime community Antichat filed a complaint against DonChicho, saying this user scammed them and had used the email address dfyz_bk@bk.ru.

The complaint said DonChicho registered on Antichat from the Transnistria Internet address 84.234.55[.]29. Searching this address in Constella reveals it has been used to register just five accounts online that have been created over the years, including one at ask.ru, where the user registered with the email address neculitzy1@yandex.ru. Constella also returns for that email address a user by the name “Ivan” at memoraleak.com and 000webhost.com.

Constella finds that the password most frequently used by the email address dfyz_bk@bk.ru was “filecast,” and that there are more than 90 email addresses associated with this password. Among them are roughly two dozen addresses with the name “Neculiti” in them, as well as the address support@donservers[.]ru.

Intel 471 says DonChicho posted to several Russian cybercrime forums that support@donservers[.]ru was his address, and that he logged into cybercrime forums almost exclusively from Internet addresses in Tiraspol, the capital of Transnistria. A review of DonChicho’s posts shows this person was banned from several forums in 2014 for scamming other users.

Cached copies of DonChicho’s vanity domain (donchicho[.]ru) show that in 2009 he was a spammer who peddled knockoff prescription drugs via Rx-Promotion, once one of the largest pharmacy spam moneymaking programs for Russian-speaking affiliates.

Mr. Neculiti told KrebsOnSecurity he has never used the nickname DonChicho.

“I may assure you that I have no relation to DonChicho nor to his bulletproof servers,” he said.

Below is a mind map that shows the connections between the accounts mentioned above.

Earlier this year, NoName began massively hitting government and industry websites in Moldova. A new report from Arbor Networks says the attacks began around March 6, when NoName alleged the government of Moldova was “craving for Russophobia.”

“Since early March, more than 50 websites have been targeted, according to posted ‘proof’ by the groups involved in attacking the country,” Arbor’s ASERT Team wrote. “While NoName seemingly initiated the ramp of attacks, a host of other DDoS hacktivists have joined the fray in claiming credit for attacks across more than 15 industries.”

CORRECTIV ACTION

The German independent news outlet Correctiv.org last week published a scathing investigative report on Stark Industries and MIRhosting, which notes that Ivan Neculiti operates his hosting companies with the help of his brother, Yuri.

Image credit: correctiv.org.

The report points out that Stark Industries continues to host a Russian disinformation news outlet called “Recent Reliable News” (RRN) that was sanctioned by the European Union in 2023 for spreading links to propaganda blogs and fake European media and government websites.

“The website was not running on computers in Moscow or St. Petersburg until recently, but in the middle of the EU, in the Netherlands, on the computers of the Neculiti brothers,” Correctiv reporters wrote.

“After a request from this editorial team, a well-known service was installed that hides the actual web host,” the report continues. “Ivan Neculiti announced that he had blocked the associated access and server following internal investigations. “We very much regret that we are only now finding out that one of our customers is a sanctioned portal,” said the company boss. However, RRN is still accessible via its servers.”

Correctiv also points to a January 2023 report from the Ukrainian government, which found servers from Stark Industries Solutions were used as part of a cyber attack on the Ukrainian news agency “Ukrinform”. Correctiv notes the notorious hacker group Sandworm — an advanced persistent threat (APT) group operated by a cyberwarfare unit of Russia’s military intelligence service — was identified by Ukrainian government authorities as responsible for that attack.

PEACE HOSTING?

Public records indicate MIRhosting is based in The Netherlands and is operated by 37-year old Andrey Nesterenko, whose personal website says he is an accomplished concert pianist who began performing publicly at a young age.

DomainTools says mirhosting[.]com is registered to Mr. Nesterenko and to Innovation IT Solutions Corp, which lists addresses in London and in Nesterenko’s stated hometown of Nizhny Novgorod, Russia.

This is interesting because according to the book Inside Cyber Warfare by Jeffrey Carr, Innovation IT Solutions Corp. was responsible for hosting StopGeorgia[.]ru, a hacktivist website for organizing cyberattacks against Georgia that appeared at the same time Russian forces invaded the former Soviet nation in 2008. That conflict was thought to be the first war ever fought in which a notable cyberattack and an actual military engagement happened simultaneously.

Responding to questions from KrebsOnSecurity, Mr. Nesterenko said he couldn’t say whether his network had ever hosted the StopGeorgia website back in 2008 because his company didn’t keep records going back that far. But he said Stark Industries Solutions is indeed one of MIRhsoting’s colocation customers.

“Our relationship is purely provider-customer,” Nesterenko said. “They also utilize multiple providers and data centers globally, so connecting them directly to MIRhosting overlooks their broader network.”

“We take any report of malicious activity seriously and are always open to information that can help us identify and prevent misuse of our infrastructure, whether involving Stark Industries or any other customer,” Nesterenko continued. “In cases where our services are exploited for malicious purposes, we collaborate fully with Dutch cyber police and other relevant authorities to investigate and take appropriate measures. However, we have yet to receive any actionable information beyond the article itself, which has not provided us with sufficient detail to identify or block malicious actors.”

In December 2022, security firm Recorded Future profiled the phishing and credential harvesting infrastructure used for Russia-aligned espionage operations by a group dubbed Blue Charlie (aka TAG-53), which has targeted email accounts of nongovernmental organizations and think tanks, journalists, and government and defense officials.

Recorded Future found that virtually all the Blue Charlie domains existed in just ten different ISPs, with a significant concentration located in two networks, one of which was MIRhosting. Both Microsoft and the UK government assess that Blue Charlie is linked to the Russian threat activity groups variously known as Callisto Group, COLDRIVER, and SEABORGIUM.

Mr. Nesterenko took exception to a story on that report from The Record, which is owned by Recorded Future.

“We’ve discussed its contents with our customer, Stark Industries,” he said. “We understand that they have initiated legal proceedings against the website in question, as they firmly believe that the claims made are inaccurate.”

Recorded Future said they updated their story with comments from Mr. Neculiti, but that they stand by their reporting.

Mr. Nesterenko’s LinkedIn profile says he was previously the foreign region sales manager at Serverius-as, a hosting company in The Netherlands that remains in the same data center as MIRhosting.

In February, the Dutch police took 13 servers offline that were used by the infamous LockBit ransomware group, which had originally bragged on its darknet website that its home base was in The Netherlands. Sources tell KrebsOnSecurity the servers seized by the Dutch police were located in Serverius’ data center in Dronten, which is also shared by MIRhosting.

Serverius-as did not respond to requests for comment. Nesterenko said MIRhosting does use one of Serverius’s data centers for its operations in the Netherlands, alongside two other data centers, but that the recent incident involving the seizure of servers has no connection to MIRhosting.

“We are legally prohibited by Dutch law and police regulations from sharing information with third parties regarding any communications we may have had,” he said.

A February 2024 report from security firm ESET found Serverius-as systems were involved in a series of targeted phishing attacks by Russia-aligned groups against Ukrainian entities throughout 2023. ESET observed that after the spearphishing domains were no longer active, they were converted to promoting rogue Internet pharmacy websites.

PEERING INTO THE VOID

A review of the Internet address ranges recently added to the network operated by Stark Industries Solutions offers some insight into its customer base, usage, and maybe even true origins. Here is a snapshot (PDF) of all Internet address ranges announced by Stark Industries so far in the month of May 2024 (this information was graciously collated by the network observability platform Kentik.com).

Those records indicate that the largest portion of the IP space used by Stark is in The Netherlands, followed by Germany and the United States. Stark says it is connected to roughly 4,600 Internet addresses that currently list their ownership as Comcast Cable Communications.

A review of those address ranges at spur.us shows all of them are connected to an entity called Proxyline, which is a sprawling proxy service based in Russia that currently says it has more than 1.6 million proxies globally that are available for rent.

Proxyline dot net.

Reached for comment, Comcast said the Internet address ranges never did belong to Comcast, so it is likely that Stark has been fudging the real location of its routing announcements in some cases.

Stark reports that it has more than 67,000 Internet addresses at Santa Clara, Calif.-based EGIhosting. Spur says the Stark addresses involving EGIhosting all map to Proxyline as well. EGIhosting did not respond to requests for comment.

EGIhosting manages Internet addresses for the Cyprus-based hosting firm ITHOSTLINE LTD (aka HOSTLINE-LTD), which is represented throughout Stark’s announced Internet ranges. Stark says it has more than 21,000 Internet addresses with HOSTLINE. Spur.us finds Proxyline addresses are especially concentrated in the Stark ranges labeled ITHOSTLINE LTD, HOSTLINE-LTD, and Proline IT.

Stark’s network list includes approximately 21,000 Internet addresses at Hockessin, De. based DediPath, which abruptly ceased operations without warning in August 2023. According to a phishing report released last year by Interisle Consulting, DediPath was the fourth most common source of phishing attacks in the year ending Oct. 2022. Spur.us likewise finds that virtually all of the Stark address ranges marked “DediPath LLC” are tied to Proxyline.

Image: Interisle Consulting.

A large number of the Internet address ranges announced by Stark in May originate in India, and the names that are self-assigned to many of these networks indicate they were previously used to send large volumes of spam for herbal medicinal products, with names like HerbalFarm, AdsChrome, Nutravo, Herbzoot and Herbalve.

The anti-spam organization SpamHaus reports that many of the Indian IP address ranges are associated with known “snowshoe spam,” a form of abuse that involves mass email campaigns spread across several domains and IP addresses to weaken reputation metrics and avoid spam filters.

It’s not clear how much of Stark’s network address space traces its origins to Russia, but big chunks of it recently belonged to some of the oldest entities on the Russian Internet (a.k.a. “Runet”).

For example, many Stark address ranges were most recently assigned to a Russian government entity whose full name is the “Federal State Autonomous Educational Establishment of Additional Professional Education Center of Realization of State Educational Policy and Informational Technologies.”

A review of Internet address ranges adjacent to this entity reveals a long list of Russian government organizations that are part of the Federal Guard Service of the Russian Federation. Wikipedia says the Federal Guard Service is a Russian federal government agency concerned with tasks related to protection of several high-ranking state officials, including the President of Russia, as well as certain federal properties. The agency traces its origins to the USSR’s Ninth Directorate of the KGB, and later the presidential security service.

Stark recently announced the address range 213.159.64.0/20 from April 27 to May 1, and this range was previously assigned to an ancient ISP in St. Petersburg, RU called the Computer Technologies Institute Ltd.

According to a post on the Russian language webmaster forum searchengines[.]ru, the domain for Computer Technologies Institute — ctinet[.]ruis the seventh-oldest domain in the entire history of the Runet.

Curiously, Stark also lists large tracts of Internet addresses (close to 48,000 in total) assigned to a small ISP in Kharkiv, Ukraine called NetAssist. Reached via email, the CEO of NetAssist Max Tulyev confirmed his company provides a number of services to PQ Hosting.

“We colocate their equipment in Warsaw, Madrid, Sofia and Thessaloniki, provide them IP transit and IPv4 addresses,” Tulyev said. “For their size, we receive relatively low number of complains to their networks. I never seen anything about their pro-Russian activity or support of Russian hackers. It is very interesting for me to see proofs of your accusations.”

Spur.us mapped the entire infrastructure of Proxyline, and found more than one million proxies across multiple providers, but by far the biggest concentration was at Stark Industries Solutions. The full list of Proxyline address ranges (.CSV) shows two other ISPs appear repeatedly throughout the list. One is Kharkiv, Ukraine based ITL LLC, also known as Information Technology Laboratories Group, and Integrated Technologies Laboratory.

The second is a related hosting company in Miami, called Green Floid LLC. Green Floid featured in a 2017 scoop by CNN, which profiled the company’s owner and quizzed him about Russian troll farms using proxy networks on Green Floid and its parent firm ITL to mask disinformation efforts tied to the Kremlin’s Internet Research Agency (IRA). At the time, the IRA was using Facebook and other social media networks to spread videos showing police brutality against African Americans in an effort to encourage protests across the United States.

Doug Madory, director of Internet analysis at Kentik, was able to see at a high level the top sources and destinations for traffic traversing Stark’s network.

“Based on our aggregate NetFlow, we see Iran as the top destination (35.1%) for traffic emanating from Stark (AS44477),” Madory said. “Specifically, the top destination is MTN Irancell, while the top source is Facebook. This data supports the theory that AS44477 houses proxy services as Facebook is blocked in Iran.”

On April 30, the security firm Malwarebytes explored an extensive malware operation that targets corporate Internet users with malicious ads. Among the sites used as lures in that campaign were fake Wall Street Journal and CNN websites that told visitors they were required to install a WSJ or CNN-branded browser extension (malware). Malwarebytes found a domain name central to that operation was hosted at Internet addresses owned by Stark Industries.

Spartacus - DLL Hijacking Discovery Tool

By: Zion3R — May 5th 2023 at 12:30


Why "Spartacus"?

If you have seen the film Spartacus from 1960, you will remember the scene where the Romans are asking for Spartacus to give himself up. The moment the real Spartacus stood up, a lot of others stood up as well and claimed to be him using the "I AM SPARTACUS" phrase.

When a process that is vulnerable to DLL Hijacking is asking for a DLL to be loaded, it's kind of asking "WHO IS VERSION.DLL?" and random directories start claiming "I AM VERSION.DLL" and "NO, I AM VERSION.DLL". And thus, Spartacus.

Did you really make yet another DLL Hijacking discovery tool?

...but with a twist as Spartacus is utilising the SysInternals Process Monitor and is parsing raw PML log files. You can leave ProcMon running for hours and discover 2nd and 3rd level (ie an app that loads another DLL that loads yet another DLL when you use a specific feature of the parent app) DLL Hijacking vulnerabilities. It will also automatically generate proxy DLLs with all relevant exports for vulnerable DLLs.


Features

  • Parsing ProcMon PML files natively. The config (PMC) and log (PML) parsers have been implemented by porting partial functionality to C# from https://github.com/eronnen/procmon-parser/. You can find the format specification here.
  • Spartacus will create proxy DLLs for all missing DLLs that were identified. For instance, if an application is vulnerable to DLL Hijacking via version.dll, Spartacus will create a version.dll.cpp file for you with all the exports included in it. Then you can insert your payload/execution technique and compile.
  • Able to process large PML files and store all DLLs of interest in an output CSV file. Local benchmark processed a 3GB file with 8 million events in 45 seconds.
  • [Defence] Monitoring mode trying to identify running applications proxying calls, as in "DLL Hijacking in progress". This is just to get any low hanging fruit and should not be relied upon.
  • Able to create proxies for export functions in order to avoid using DllMain. This technique was inspired and implemented from the walkthrough described at https://www.redteam.cafe/red-team/dll-sideloading/dll-sideloading-not-by-dllmain, by Shantanu Khandelwal. For this to work Ghidra is required.

Screenshots

Spartacus Execution

CSV Output

Output Exports

Export DLL Functions

Usage

Execution Flow

  1. Generate a ProcMon (PMC) config file on the fly, based on the arguments passed. The filters that will be set are:
    • Operation is CreateFile.
    • Path ends with .dll.
    • Process name is not procmon.exe or procmon64.exe.
    • Enable Drop Filtered Events to ensure minimum PML output size.
    • Disable Auto Scroll.
  2. Execute Process Monitor.
  3. Halt its execution until the user presses ENTER.
  4. Terminates Process Monitor.
  5. Parses the output Event Log (PML) file.
    1. Creates a CSV file with all the NAME_NOT_FOUND and PATH_NOT_FOUND DLLs.
    2. Compares the DLLs from above and tries to identify the DLLs that were actually loaded.
    3. For every "found" DLL it generates a proxy DLL with all its export functions.

Command Line Arguments

Argument Description
--pml Location (file) to store the ProcMon event log file. If the file exists, it will be overwritten. When used with --existing-log it will indicate the event log file to read from and will not be overwritten.
--pmc Define a custom ProcMon (PMC) file to use. This file will not be modified and will be used as is.
--csv Location (file) to store the CSV output of the execution. This file will include only the DLLs that were marked as NAME_NOT_FOUND, PATH_NOT_FOUND, and were in user-writable locations (it excludes anything in the Windows and Program Files directories)
--exe Define process names (comma separated) that you want to track, helpful when you are interested only in a specific process.
--exports Location (folder) in which all the proxy DLL files will be saved. Proxy DLL files will only be generated if this argument is used.
--procmon Location (file) of the SysInternals Process Monitor procmon.exe or procmon64.exe
--proxy-dll-template Define a DLL template to use for generating the proxy DLL files. Only relevant when --exports is used. All #pragma exports are inserted by replacing the %_PRAGMA_COMMENTS_% string, so make sure your template includes that string in the relevant location.
--existing-log Switch to indicate that Spartacus should process an existing ProcMon event log file (PML). To indicate the event log file use --pml, useful when you have been running ProcMon for hours or used it in Boot Logging.
--all By default any DLLs in the Windows or Program Files directories will be skipped. Use this to include those directories in the output.
--detect Try to identify DLLs that are proxying calls (like 'DLL Hijacking in progress'). This isn't a feature to be relied upon, it's there to get the low hanging fruit.
--verbose Enable verbose output.
--debug Enable debug output.
--generate-proxy Switch to indicate that Spartacus will be creating proxy functions for all identified export functions.
--ghidra Used only with --generate-proxy. Absolute path to Ghidra's 'analyzeHeadless.bat' file.
--dll Used only with --generate-proxy. Absolute path to the DLL you want to proxy.
--output-dir Used only with --generate-proxy. Absolute path to the directory where the solution of the proxy will be stored. This directory should not exist, and will be auto-created.
--only-proxy Used only with --generate-proxy. Comma separated string to indicate functions to clone. Such as 'WTSFreeMemory,WTSFreeMemoryExA,WTSSetUserConfigA'

Examples

Collect all events and save them into C:\Data\logs.pml. All vulnerable DLLs will be saved as C:\Data\VulnerableDLLFiles.csv and all proxy DLLs in C:\Data\DLLExports.

--procmon C:\SysInternals\Procmon.exe --pml C:\Data\logs.pml --csv C:\Data\VulnerableDLLFiles.csv --exports C:\Data\DLLExports --verbose

Collect events only for Teams.exe and OneDrive.exe.

--procmon C:\SysInternals\Procmon.exe --pml C:\Data\logs.pml --csv C:\Data\VulnerableDLLFiles.csv --exports C:\Data\DLLExports --verbose --exe "Teams.exe,OneDrive.exe"

Collect events only for Teams.exe and OneDrive.exe, and use a custom proxy DLL template at C:\Data\myProxySkeleton.cpp.

--procmon C:\SysInternals\Procmon.exe --pml C:\Data\logs.pml --csv C:\Data\VulnerableDLLFiles.csv --exports C:\Data\DLLExports --verbose --exe "Teams.exe,OneDrive.exe" --proxy-dll-template C:\Data\myProxySkeleton.cpp

Collect events only for Teams.exe and OneDrive.exe, but don't generate proxy DLLs.

--procmon C:\SysInternals\Procmon.exe --pml C:\Data\logs.pml --csv C:\Data\VulnerableDLLFiles.csv --verbose --exe "Teams.exe,OneDrive.exe"

Parse an existing PML event log output, save output to CSV, and generate proxy DLLs.

--existing-log --pml C:\MyData\SomeBackup.pml --csv C:\Data\VulnerableDLLFiles.csv --exports C:\Data\DLLExports

Run in monitoring mode and try to detect any applications that is proxying DLL calls.

--detect

Create proxies for all identified export functions.

--generate-proxy --ghidra C:\ghidra\support\analyzeHeadless.bat --dll C:\Windows\System32\userenv.dll --output-dir C:\Projects\spartacus-wtsapi32 --verbose

Create a proxy only for a specific export function.

--generate-proxy --ghidra C:\ghidra\support\analyzeHeadless.bat --dll C:\Windows\System32\userenv.dll --output-dir C:\Projects\spartacus-wtsapi32 --verbose --only-proxy "ExpandEnvironmentStringsForUserW"

Note: When generating proxies for export functions, the solution that is created also replicates VERSIONINFO and timestomps the target DLL to match the date of the source one (using PowerShell).

Proxy DLL Template

Below is the template that is used when generating proxy DLLs, the generated #pragma statements are inserted by replacing the %_PRAGMA_COMMENTS_% string.

The only thing to be aware of is that the pragma DLL will be using a hardcoded path of its location rather than trying to load it dynamically.

#pragma once

%_PRAGMA_COMMENTS_%

#include <windows.h>
#include <string>
#include <atlstr.h>

VOID Payload() {
// Run your payload here.
}

BOOL WINAPI DllMain(HINSTANCE hinstDLL, DWORD fdwReason, LPVOID lpReserved)
{
switch (fdwReason)
{
case DLL_PROCESS_ATTACH:
Payload();
break;
case DLL_THREAD_ATTACH:
break;
case DLL_THREAD_DETACH:
break;
case DLL_PROCESS_DETACH:
break;
}
return TRUE;
}

If you wish to use your own template, just make sure the %_PRAGMA_COMMENTS_% is in the right place.

What is a VPN and How Does it Increase Your Online Security and Privacy?

By: Trend Micro — August 31st 2020 at 12:56

The number of VPN users has grown considerably over the past few years. According to the report of Go-Globe, 25% of netizens worldwide have used a VPN at least once in the last 30 days. Recently, VPN usage has surged in many countries and its popularity may see VPN usage surpass the estimated profit of USD$27.10 billion by the end of 2020. The VPN global market only seems to increase as time goes by. So, why is that? What do VPNs provide that make them so attractive?

What is a VPN?

A VPN, or a Virtual Private Network, creates a secure communication “tunnel” from your computer to the internet. It encrypts your connection and prevents others from seeing the data you’re transferring. This keeps your data secure from any spying attempts—including from home over your wired connection, but particularly on public Wi-Fi networks, when you’re out and about in places such as coffee shops, restaurants, airports and hotels. It helps ensure that no one can steal your personal details, passwords, or credit card information.

How does a VPN work and why you need a VPN service?

Among other things, a VPN can conceal your IP address to make your online actions virtually untraceable and anonymous, providing greater privacy for everything you do. In fact, there are so many ways a VPN can protect your privacy and security, we need to take a deeper look at what other benefits a VPN can provide.

    1. Safeguard personal information

    This is the era of mobility and most transactions are being done by people on-the-go using their mobile devices to exchange data over public networks. From online shopping, to mobile banking or simply checking emails and social media accounts, these activities can expose your personal information and sensitive data to hackers and cybercriminals. This particularly applies to users relying on public Wi-Fi. Using a VPN will help to mitigate unwanted leakage or theft by securing data in transit to and from the systems that typically try to collect and store your private data.

      1. Access better streaming contents from other locations

      One of the main drivers for using a VPN is to access better streaming content and restricted websites from the region you’re accessing the internet from. This may be true in your own country, but when traveling abroad, there are also chances that you cannot visit a popular website or a social media platform from the country you’re visiting. While using a VPN, you can connect to an IP address in your country and have full access to your favorite media contents and avoid wasting membership fees that you will likely pay for this streaming service.

        1. Enhance browsing privacy

        Some retail apps, social media platforms, and search engines continuously collect and analyze results of your search history. They keep track of all your browsing activities such as items you viewed, contents you liked, and things you tapped and clicked, so they can provide you with more targeted contents and monetize these by showing the same information in your feed through ads.

        Note that, simply clearing your browsing history does not completely remove traces of these searches, and targeted ads can get annoying. This is where a VPN can help enhance your browsing privacy. The VPN hides your browser cached data and location from advertisers, which prevents them from serving up content based on your searches and location.

          1. Save cost on communicating with family and friends abroad

          Another motivating factor for the use of a VPN is to save on the cost of communicating with families and friends abroad. There are countries implementing restrictions on the use of certain messaging apps, banning their services. If you are planning to visit a country with such a restriction, a VPN can bypass this constraint, which allows you to make use of your trusted messaging app, eliminate the cost of long-distance calls to family and friends while abroad—and at the same time, maintain the level of security and encryption the messaging app provides.

            1. Escape content-based bandwidth-throttling

            The internet has evolved into streaming more content—videos, music, and more—and ISPs have responded by making higher data usage and higher throughput (bandwidth) pay-as-you-use-more services. But content is still at issue, particularly after the December 2017 FCC ruling. Potential ISP throttling based on content type, source, or destination (e.g., BitTorrent traffic), which could give priority to business over personal usage, is one of the reasons why everyday people are using VPN services, because a VPN provides more usage anonymity, preventing ISPs from potentially tracking your activities and limiting your bandwidth usage accordingly.

            Choosing the right VPN for you

            Now that you have some understanding of what a VPN is, and what benefits it can give you, it is also important to choose the right VPN for you.

            Due to regulatory requirements and laws governing data privacy and securing personal information online, the demand for VPNs is growing. In response, there are a large number of VPN providers in the market today. So how do you choose a reliable VPN? Here are some criteria to help you pick one that best suits your needs:

            • Faster and more data is better. Using a VPN can often decrease the speed of your internet connection, so you should pick a provider that has a good number of servers and locations and doesn’t pre-throttle your bandwidth. Some also have data limits, so you should opt for those with a higher data limit per month
            • Provides the best encryption. Look for a VPN providing sophisticated ciphers such as 256-bit AES end-to-end encryption.
            • Ensures safe browsing. Look for VPN that can filter and block malicious websites, online fraud, and internet scams and automatically safeguard your internet connection.
            • Provides full anonymity. It is crucial that a VPN vendor has a clear privacy policy. Trusted VPNs will not track the user’s websites, payment information, or online transactions, and do not keep logs.
            • Supports simultaneous devices. Select a VPN that is compatible with your devices and operating systems and can provide you a good number of simultaneous connections on your devices.
            • Cost versus use case. Heavier business usage should be contrasted with everyday consumer use. To pay less for the service (VPNs typically cost from $5 to $12 per month per device, though multi-device bundles are less), you might accept some data limits, if your use case is lighter; sacrifice some speed, if you’re not streaming movies when you’re out and about, (unlikely during the coronavirus lockdown); or some cross-regional server-selection capability, if you’re not travelling in content-restricted regions (since out-of-country travel is also being hampered by the pandemic).

            Trend Micro’s Home Division provides two low-cost, safety-focused VPN solutions for everyday users: Trend Micro VPN Proxy One and Trend Micro Wi-Fi Protection, both of which can address light-to-medium VPN needs and meet most of the checklist criteria above.

            Trend Micro VPN Proxy One offers fast, secure, stable and anonymous proxy connections for you to access various websites and applications. It connects to the best Trend Micro VPN server intelligently, without you having to do it, and does not limit bandwidth consumption. Trend Micro VPNs do not track your online activities, ensuring you a secure digital life and protecting your online privacy. Trend Micro VPN Proxy One is targeted to Mac and iOS devices.

            Trend Micro Wi-Fi Protection turns any public hotspot into a secure Wi-Fi network and VPN with bank-grade data encryption to keep your information safe from hackers. While your VPN is active, Trend Micro Wi-Fi Protection provides exceptional web threat protection and checks websites you visit to safeguard your browsing from online fraud and internet scam. The VPN automatically kicks in when connecting to a Wi-Fi network with low security, such as one with no encryption. Trend Micro Wi-Fi Protection is available for all platforms (PC, Mac, Android, and iOS). Bundles can be purchased for multiple devices and platforms and some bundles can include other Trend Micro products, depending on the region.
