Who’s Behind the SWAT USA Reshipping Service?

By BrianKrebs

Last week, KrebsOnSecurity broke the news that one of the largest cybercrime services for laundering stolen merchandise was hacked recently, exposing its internal operations, finances and organizational structure. In today’s Part II, we’ll examine clues about the real-life identity of “Fearlless,” the nickname chosen by the proprietor of the SWAT USA Drops service.

Based in Russia, SWAT USA recruits people in the United States to reship packages containing pricey electronics that are purchased with stolen credit cards. As detailed in this Nov. 2 story, SWAT currently employs more than 1,200 U.S. residents, all of whom will be cut loose without a promised payday at the end of their first month reshipping stolen goods.

The current co-owner of SWAT, a cybercriminal who uses the nickname “Fearlless,” operates primarily on the cybercrime forum Verified. This Russian-language forum has tens of thousands of members, and it has suffered several hacks that exposed more than a decade’s worth of user data and direct messages.

January 2021 posts on Verified show that Fearlless and his partner Universalo purchased the SWAT reshipping business from a Verified member named SWAT, who’d been operating the service for years. SWAT agreed to transfer the business in exchange for 30 percent of the net profit over the ensuing six months.

Cyber intelligence firm Intel 471 says Fearlless first registered on Verified in February 2013. The email address Fearlless used on Verified leads nowhere, but a review of Fearlless’ direct messages on Verified indicates this user originally registered on Verified a year earlier as a reshipping vendor, under the alias “Apathyp.”

There are two clues supporting the conclusion that Apathyp and Fearlless are the same person. First, the Verified administrators warned Apathyp he had violated the forum’s rules barring the use of multiple accounts by the same person, and that Verified’s automated systems had detected that Apathyp and Fearlless were logging in from the same device.  Second, in his earliest private messages on Verified, Fearlless told others to contact him on an instant messenger address that Apathyp had claimed as his.

Intel 471 says Apathyp registered on Verified using the email address triploo@mail.ru. A search on that email address at the breach intelligence service Constella Intelligence found that a password commonly associated with it was “niceone.” But the triploo@mail.ru account isn’t connected to much else that’s interesting except a now-deleted account at Vkontakte, the Russian answer to Facebook.

However, in Sept. 2020, Apathyp sent a private message on Verified to the owner of a stolen credit card shop, saying his credentials no longer worked. Apathyp told the proprietor that his chosen password on the service was “12Apathy.”

A search on that password at Constella reveals it was used by just four different email addresses, two of which are particularly interesting: gezze@yandex.ru and gezze@mail.ru. Constella discovered that both of these addresses were previously associated with the same password as triploo@mail.ru — “niceone,” or some variation thereof.

Constella found that years ago gezze@mail.ru was used to create a Vkontakte account under the name Ivan Sherban (former password: “12niceone“) from Magnitogorsk, an industrial city in the southern region of Russia. That same email address is now tied to a Vkontakte account for an Ivan Sherban who lists his home as Saint Petersburg, Russia. Sherban’s profile photo shows a heavily tattooed, muscular and recently married individual with his beautiful new bride getting ready to drive off in a convertible sports car.

A pivotal clue for validating the research into Apathyp/Fearlless came from the identity intelligence firm myNetWatchman, which found that gezze@mail.ru at one time used the passwords “геззи1991” (gezze1991) and “gezze18081991.”

Care to place a wager on when Vkontakte says is Mr. Sherban’s birthday? Ten points if you answered August 18 (18081991).

Mr. Sherban did not respond to multiple requests for comment.

Russian Reshipping Service ‘SWAT USA Drop’ Exposed

By BrianKrebs

The login page for the criminal reshipping service SWAT USA Drop.

One of the largest cybercrime services for laundering stolen merchandise was hacked recently, exposing its internal operations, finances and organizational structure. Here’s a closer look at the Russia-based SWAT USA Drop Service, which currently employs more than 1,200 people across the United States who are knowingly or unwittingly involved in reshipping expensive consumer goods purchased with stolen credit cards.

Among the most common ways that thieves extract cash from stolen credit card accounts is through purchasing pricey consumer goods online and reselling them on the black market. Most online retailers grew wise to these scams years ago and stopped shipping to regions of the world most frequently associated with credit card fraud, including Eastern Europe, North Africa, and Russia.

But such restrictions have created a burgeoning underground market for reshipping scams, which rely on willing or unwitting residents in the United States and Europe to receive stolen goods and relay them to crooks living in the embargoed areas.

Services like SWAT are known as “Drops for stuff” on cybercrime forums. The “drops” are people who have responded to work-at-home package reshipping jobs advertised on craigslist.com and job search sites. Most reshipping scams promise employees a monthly salary and even cash bonuses. In reality, the crooks in charge almost always stop communicating with drops just before the first payday, usually about a month after the drop ships their first package.

The packages arrive with prepaid shipping labels that are paid for with stolen credit card numbers, or with hijacked online accounts at FedEx and the US Postal Service. Drops are responsible for inspecting and verifying the contents of shipments, attaching the correct shipping label to each package, and sending them off via the appropriate shipping company.

SWAT takes a percentage cut (up to 50 percent) where “stuffers” — thieves armed with stolen credit card numbers — pay a portion of each product’s retail value to SWAT as the reshipping fee. The stuffers use stolen cards to purchase high-value products from merchants and have the merchants ship the items to the drops’ address. Once the drops receive and successfully reship the stolen packages, the stuffers then sell the products on the local black market.

The SWAT drop service has been around in various names and under different ownership for almost a decade. But in early October 2023, SWAT’s current co-owner — a Russian-speaking individual who uses the handle “Fearlless” — took to his favorite cybercrime forum to lodge a formal complaint against the owner of a competing reshipping service, alleging his rival had hacked SWAT and was trying to poach his stuffers and reshippers by emailing them directly.

Milwaukee-based security firm Hold Security shared recent screenshots of a working SWAT stuffer’s user panel, and those images show that SWAT currently lists more than 1,200 drops in the United States that are available for stuffers to rent. The contact information for Kareem, a young man from Maryland, was listed as an active drop. Contacted by KrebsOnSecurity, Kareem agreed to speak on condition that his full name not be used in this story.

A SWAT panel for stuffers/customers. This page lists the rules of the service, which do not reimburse stuffers for “acts of god,” i.e. authorities seizing stolen goods or arresting the drop.

Kareem said he’d been hired via an online job board to reship packages on behalf of a company calling itself CTSI, and that he’s been receiving and reshipping iPads and Apple watches for several weeks now. Kareem was less than thrilled to learn he would probably not be getting his salary on the promised payday, which was coming up in a few days.

Kareem said he was instructed to create an account at a website called portal-ctsi[.]com, where each day he was expected to log in and check for new messages about pending shipments. Anyone can sign up at this website as a potential reshipping mule, although doing so requires applicants to share a great deal of personal and financial information, as well as copies of an ID or passport matching the supplied name.

A SWAT panel for stuffers/customers, listing hundreds of drops in the United States by their status. “Going to die” are those who are about to be let go without promised payment, or who have quit on their own.

On a suspicion that the login page for portal-ctsi[.]com might be a custom coding job, KrebsOnSecurity selected “view source” from the homepage to expose the site’s HTML code. Grabbing a snippet of that code (e.g., “smarty/default/jui/js/jquery-ui-1.9.2.min.js”) and searching on it at publicwww.com reveals more than four dozen other websites running the same login panel. And all of those appear to be geared toward either stuffers or drops.

In fact, more than half of the domains that use this same login panel actually include the word “stuffer” in the login URL, according to publicwww. Each of the domains below that end in “/user/login.php” are sites for active and prospective drops, and each corresponds to a unique fake company that is responsible for managing its own stable of drops:

Why so many websites? In practice, all drops are cut loose within approximately 30 days of their first shipment — just before the promised paycheck is due. Because of this constant churn, each stuff shop operator must be constantly recruiting new drops. Also, with this distributed setup, even if one reshipping operation gets shut down (or exposed online), the rest can keep on pumping out dozens of packages a day.

A 2015 academic study (PDF) on criminal reshipping services found the average financial hit from a reshipping scheme per cardholder was $1,156.93. That study looked into the financial operations of several reshipping schemes, and estimated that approximately 1.6 million credit and debit cards are used to commit at least $1.8 billion in reshipping fraud each year.

It’s not hard to see how reshipping can be a profitable enterprise for card crooks. For example, a stuffer buys a stolen payment card off the black market for $10, and uses that card to purchase more than $1,100 worth of goods. After the reshipping service takes its cut (~$550), and the stuffer pays for his reshipping label (~$100), the stuffer receives the stolen goods and sells them on the black market in Russia for $1,400. He has just turned a $10 investment into more than $700. Rinse, wash, and repeat.

The breach at SWAT exposed not only the nicknames and contact information for all of its stuffers and drops, but also the group’s monthly earnings and payouts. SWAT apparently kept its books in a publicly accessible Google Sheets document, and that document reveals Fearlless and his business partner each routinely made more than $100,000 every month operating their various reshipping businesses.

The exposed SWAT financial records show this crime group has tens of thousands of dollars worth of expenses each month, including payments for the following recurring costs:

-advertising the service on crime forums and via spam;
-people hired to re-route packages, usually by voice over the phone;
-third-party services that sell hacked/stolen USPS/Fedex labels;
-“drops test” services, contractors who will test the honesty of drops by sending them fake jewelry;
-“documents,” e.g. sending drops to physically pick up legal documents for new phony front companies.

The spreadsheet also included the cryptocurrency account numbers that were to be credited each month with SWAT’s earnings. Unsurprisingly, a review of the blockchain activity tied to the bitcoin addresses listed in that document shows that many of them have a deep association with cybercrime, including ransomware activity and transactions at darknet sites that peddle stolen credit cards and residential proxy services.

The information leaked from SWAT also has exposed the real-life identity and financial dealings of its principal owner — Fearlless, a.k.a. “SwatVerified.” We’ll hear more about Fearlless in Part II of this story. Stay tuned.

NJ Man Hired Online to Firebomb, Shoot at Homes Gets 13 Years in Prison

By BrianKrebs

A 22-year-old New Jersey man has been sentenced to more than 13 years in prison for participating in a firebombing and a shooting at homes in Pennsylvania last year. Patrick McGovern-Allen was the subject of a Sept. 4, 2022 story here about the emergence of “violence-as-a-service” offerings, where random people from the Internet hire themselves out to perform a variety of local, physical attacks, including firebombing a home, “bricking” windows, slashing tires, or performing a drive-by shooting at someone’s residence.

McGovern-Allen, of Egg Harbor Township, N.J., was arrested Aug. 12, 2022 on an FBI warrant, which showed he was part of a group of cybercriminals who are settling scores with one another by hiring people to carry out violent attacks on their rivals.

That Sept. 2022 story about his arrest included links to two videos released on Telegram that were recorded and shared by McGovern-Allen and/or a co-conspirator as “proof” that they had carried out the attacks as hired.

The first showed two young men tossing a Molotov Cocktail at the side of a residence in Abington Township, Pa, setting it ablaze. The second featured two men with handguns unloading multiple rounds haphazardly into the first story of a house in West Chester, Pa. Fortunately in both cases, the occupants of the homes were unharmed in the attacks.

Federal prosecutors said McGovern-Allen went by the alias “Tongue” on Discord, and that in one chat he was quite explicit about his violence-as-a-service offering.

“In the chats, [Tongue] tells other Discord users that he was the person who shot K.M.’s house and that he was willing to commit firebombings using Molotov Cocktails,” the complaint against McGovern-Allen explains. “For example, in one Discord chat from March 2022, [the defendant] states ‘if you need anything done for $ lmk [“let me know”]/I did a shooting/Molotov/but I can also do things for ur entertainment.”

The chat channels that Tongue frequented have hundreds to thousands of members each, and some of the more interesting solicitations on these communities are job offers for in-person assignments and tasks that can be found if one searches for posts titled, “If you live near,” or “IRL job” — short for “in real life” job. A number of these classified ads are in service of performing “brickings,” where someone is hired to visit a specific address and toss a brick through the target’s window.

McGovern-Allen was in the news not long ago. According to a Sept. 2020 story from The Press of Atlantic City, a then 19-year-old Patrick McGovern-Allen was injured after driving into a building and forcing residents from their home.

“Police found a 2007 Lexus, driven by Patrick McGovern-Allen, 19, that had lost control and left the road, crashing into the eastern end of the 1600 building,” the story recounted. “The car was driven through the steps that provide access to the second-floor apartments, destroying them, and also caused damage to the outer wall.”

A copy of McGovern-Allen’s sentencing statement says he pleaded guilty to three criminal counts, including two for stalking, and one for the use of fire in commission of a federal felony. The judge in the case gave McGovern-Allen 160 months in prison — about 13.3 years. After completing his sentence, McGovern-Allen will be on supervised release for three years.

Tech CEO Sentenced to 5 Years in IP Address Scheme

By BrianKrebs

Amir Golestan, the 40-year-old CEO of the Charleston, S.C. based technology company Micfo LLC, has been sentenced to five years in prison for wire fraud. Golestan’s sentencing comes nearly two years after he pleaded guilty to using an elaborate network of phony companies to secure more than 735,000 Internet Protocol (IP) addresses from the American Registry for Internet Numbers (ARIN), the nonprofit which oversees IP addresses assigned to entities in the U.S., Canada, and parts of the Caribbean.

Amir Golestan, the former CEO of Micfo.

In 2018, ARIN sued Golestan and Micfo, alleging they had obtained hundreds of thousands of IP addresses under false pretenses. ARIN and Micfo settled that dispute in arbitration, with Micfo returning most of the addresses that it hadn’t already sold.

ARIN’s civil case caught the attention of federal prosecutors in South Carolina, who in May 2019 filed criminal wire fraud charges against Golestan, alleging he’d orchestrated a network of shell companies and fake identities to prevent ARIN from knowing the addresses were all going to the same buyer.

Prosecutors showed that each of those shell companies involved the production of notarized affidavits in the names of people who didn’t exist. As a result, the government was able to charge Golestan with 20 counts of wire fraud — one for each payment made by the phony companies that bought the IP addresses from ARIN.

Golestan initially sought to fight those charges. But on just the second day of his trial in November 2021, Golestan changed his mind and pleaded guilty to 20 counts of wire fraud in connection with the phantom companies he used to secure the IP addresses. Prosecutors estimated those addresses were valued at between $10 million and $14 million.

ARIN says the 5-year sentence handed down by the South Carolina judge “sends an important message of deterrence to other parties contemplating fraudulent schemes to obtain or transfer Internet resources.”

“Those who seek to defraud ARIN (or other Regional Internet Registries) are subject to costly and serious civil litigation, criminal charges, and, ultimately, a lengthy term of incarceration,” reads a statement from ARIN on Golestan’s sentencing.

By 2013, a number of Micfo’s customers had landed on the radar of Spamhaus, a group that many network operators rely upon to stem the tide of junk email. Shortly after Spamhaus started blocking Micfo’s IP address ranges, Micfo shifted gears and began reselling IP addresses mainly to companies marketing “virtual private networking” or VPN services that help customers hide their real IP addresses online.

Golestan did not respond to a request for comment. But in a 2020 interview with KrebsOnSecurity, Golestan claimed that Micfo was at one point responsible for brokering roughly 40 percent of the IP addresses used by the world’s largest VPN providers. Throughout that conversation, Golestan maintained his innocence, even as he explained that the creation of the phony companies was necessary to prevent entities like Spamhaus from interfering with his business going forward.

There are fewer than four billion so-called “Internet Protocol version 4” or IPv4 addresses available for use, but the vast majority of them have already been allocated. The global dearth of available IP addresses has turned them into a commodity wherein each IPv4 address can fetch between $15-$25 on the open market.

This has led to boom times for those engaged in the acquisition and sale of IP address blocks, but it has likewise emboldened those who specialize in absconding with and spamming from dormant IP address blocks without permission from the rightful owners.

The U.S Department of Justice says Golestan will serve 60 months in prison, followed by a 2-year term of court-ordered supervision. The Micfo CEO also was ordered to pay nearly $77,000 in restitution to ARIN for its work in assisting federal prosecutors.

Of the 103 flaws, 13 are rated Critical and 90 are rated Important in severity. This is apart from 18 security vulnerabilities addressed in its Chromium-based Edge browser since the second Tuesday of September. The two

Patch Tuesday, October 2023 Edition

By BrianKrebs

Microsoft today issued security updates for more than 100 newly-discovered vulnerabilities in its Windows operating system and related software, including four flaws that are already being exploited. In addition, Apple recently released emergency updates to quash a pair of zero-day bugs in iOS.

Apple last week shipped emergency updates in iOS 17.0.3 and iPadOS 17.0.3 in response to active attacks. The patch fixes CVE-2023-42724, which attackers have been using in targeted attacks to elevate their access on a local device.

Apple said it also patched CVE-2023-5217, which is not listed as a zero-day bug. However, as Bleeping Computer pointed out, this flaw is caused by a weakness in the open-source “libvpx” video codec library, which was previously patched as a zero-day flaw by Google in the Chrome browser and by Microsoft in Edge, Teams, and Skype products. For anyone keeping count, this is the 17th zero-day flaw that Apple has patched so far this year.

Fortunately, the zero-days affecting Microsoft customers this month are somewhat less severe than usual, with the exception of CVE-2023-44487. This weakness is not specific to Windows but instead exists within the HTTP/2 protocol used by the World Wide Web: Attackers have figured out how to use a feature of HTTP/2 to massively increase the size of distributed denial-of-service (DDoS) attacks, and these monster attacks reportedly have been going on for several weeks now.

Amazon, Cloudflare and Google all released advisories today about how they’re addressing CVE-2023-44487 in their cloud environments. Google’s Damian Menscher wrote on Twitter/X that the exploit — dubbed a “rapid reset attack” — works by sending a request and then immediately cancelling it (a feature of HTTP/2). “This lets attackers skip waiting for responses, resulting in a more efficient attack,” Menscher explained.

Natalie Silva, lead security engineer at Immersive Labs, said this flaw’s impact to enterprise customers could be significant, and lead to prolonged downtime.

“It is crucial for organizations to apply the latest patches and updates from their web server vendors to mitigate this vulnerability and protect against such attacks,” Silva said. In this month’s Patch Tuesday release by Microsoft, they have released both an update to this vulnerability, as well as a temporary workaround should you not be able to patch immediately.”

Microsoft also patched zero-day bugs in Skype for Business (CVE-2023-41763) and Wordpad (CVE-2023-36563). The latter vulnerability could expose NTLM hashes, which are used for authentication in Windows environments.

“It may or may not be a coincidence that Microsoft announced last month that WordPad is no longer being updated, and will be removed in a future version of Windows, although no specific timeline has yet been given,” said Adam Barnett, lead software engineer at Rapid7. “Unsurprisingly, Microsoft recommends Word as a replacement for WordPad.”

Other notable bugs addressed by Microsoft include CVE-2023-35349, a remote code execution weakness in the Message Queuing (MSMQ) service, a technology that allows applications across multiple servers or hosts to communicate with each other. This vulnerability has earned a CVSS severity score of 9.8 (10 is the worst possible). Happily, the MSMQ service is not enabled by default in Windows, although Immersive Labs notes that Microsoft Exchange Server can enable this service during installation.

Speaking of Exchange, Microsoft also patched CVE-2023-36778,  a vulnerability in all current versions of Exchange Server that could allow attackers to run code of their choosing. Rapid7’s Barnett said successful exploitation requires that the attacker be on the same network as the Exchange Server host, and use valid credentials for an Exchange user in a PowerShell session.

For a more detailed breakdown on the updates released today, see the SANS Internet Storm Center roundup. If today’s updates cause any stability or usability issues in Windows, AskWoody.com will likely have the lowdown on that.

Please consider backing up your data and/or imaging your system before applying any updates. And feel free to sound off in the comments if you experience any difficulties as a result of these patches.

Phishers Spoof USPS, 12 Other Natl’ Postal Services

By BrianKrebs

The fake USPS phishing page.

Recent weeks have seen a sizable uptick in the number of phishing scams targeting U.S. Postal Service (USPS) customers. Here’s a look at an extensive SMS phishing operation that tries to steal personal and financial data by spoofing the USPS, as well as postal services in at least a dozen other countries.

KrebsOnSecurity recently heard from a reader who received an SMS purporting to have been sent by the USPS, saying there was a problem with a package destined for the reader’s address. Clicking the link in the text message brings one to the domain usps.informedtrck[.]com.

The landing page generated by the phishing link includes the USPS logo, and says “Your package is on hold for an invalid recipient address. Fill in the correct address info by the link.” Below that message is a “Click update” button that takes the visitor to a page that asks for more information.

The remaining buttons on the phishing page all link to the real USPS.com website. After collecting your address information, the fake USPS site goes on to request additional personal and financial data.

This phishing domain was recently registered and its WHOIS ownership records are basically nonexistent. However, we can find some compelling clues about the extent of this operation by loading the phishing page in Developer Tools, a set of debugging features built into Firefox, Chrome and Safari that allow one to closely inspect a webpage’s code and operations.

Check out the bottom portion of the screenshot below, and you’ll notice that this phishing site fails to load some external resources, including an image from a link called fly.linkcdn[.]to.

A search on this domain at the always-useful URLscan.io shows that fly.linkcdn[.]to is tied to a slew of USPS-themed phishing domains. Here are just a few of those domains (links defanged to prevent accidental clicking):

As we can see in the screenshot below, the developer tools console for informedtrck[.]com complains that the site is unable to load a Google Analytics code — UA-80133954-3 — which apparently was rejected for pointing to an invalid domain.

Notice the highlighted Google Analytics code exposed by a faulty Javascript element on the phishing website. Click to enlarge. That code actually belongs to the USPS.

The valid domain for that Google Analytics code is the official usps.com website. According to dnslytics.com, that same analytics code has shown up on at least six other nearly identical USPS phishing pages dating back nearly as many years, including onlineuspsexpress[.]com, which DomainTools.com says was registered way back in September 2018 to an individual in Nigeria.

A different domain with that same Google Analytics code that was registered in 2021 is peraltansepeda[.]com, which archive.org shows was running a similar set of phishing pages targeting USPS users. DomainTools.com indicates this website name was registered by phishers based in Indonesia.

DomainTools says the above-mentioned USPS phishing domain stamppos[.]com was registered in 2022 via Singapore-based Alibaba.com, but the registrant city and state listed for that domain says “Georgia, AL,” which is not a real location.

Alas, running a search for domains registered through Alibaba to anyone claiming to reside in Georgia, AL reveals nearly 300 recent postal phishing domains ending in “.top.” These domains are either administrative domains obscured by a password-protected login page, or are .top domains phishing customers of the USPS as well as postal services serving other countries.

Those other nations include the Australia Post, An Post (Ireland), Correos.es (Spain), the Costa Rican post, the Chilean Post, the Mexican Postal Service, Poste Italiane (Italy), PostNL (Netherlands), PostNord (Denmark, Norway and Sweden), and Posti (Finland). A complete list of these domains is available here (PDF).

A phishing page targeting An Post, the state-owned provider of postal services in Ireland.

The Georgia, AL domains at Alibaba also encompass several that spoof sites claiming to collect outstanding road toll fees and fines on behalf of the governments of Australia, New Zealand and Singapore.

An anonymous reader wrote in to say they submitted fake information to the above-mentioned phishing site usps.receivepost[.]com via the malware sandbox any.run. A video recording of that analysis shows that the site sends any submitted data via an automated bot on the Telegram instant messaging service.

The traffic analysis just below the any.run video shows that any data collected by the phishing site is being sent to the Telegram user @chenlun, who offers to sell customized source code for phishing pages. From a review of @chenlun’s other Telegram channels, it appears this account is being massively spammed at the moment — possibly thanks to public attention brought by this story.

Meanwhile, researchers at DomainTools recently published a report on an apparently unrelated but equally sprawling SMS-based phishing campaign targeting USPS customers that appears to be the work of cybercriminals based in Iran.

Phishers tend to cast a wide net and often spoof entities that are broadly used by the local population, and few brands are going to have more household reach than domestic mail services. In June, the United Parcel Service (UPS) disclosed that fraudsters were abusing an online shipment tracking tool in Canada to send highly targeted SMS phishing messages that spoofed the UPS and other brands.

With the holiday shopping season nearly upon us, now is a great time to remind family and friends about the best advice to sidestep phishing scams: Avoid clicking on links or attachments that arrive unbidden in emails, text messages and other mediums. Most phishing scams invoke a temporal element that warns of negative consequences should you fail to respond or act quickly.

If you’re unsure whether the message is legitimate, take a deep breath and visit the site or service in question manually — ideally, using a browser bookmark so as to avoid potential typosquatting sites.

A Closer Look at the Snatch Data Ransom Group

By BrianKrebs

Earlier this week, KrebsOnSecurity revealed that the darknet website for the Snatch ransomware group was leaking data about its users and the crime gang’s internal operations. Today, we’ll take a closer look at the history of Snatch, its alleged founder, and their claims that everyone has confused them with a different, older ransomware group by the same name.

According to a September 20, 2023 joint advisory from the FBI and the U.S. Cybersecurity and Infrastructure Security Administration (CISA), Snatch was originally named Team Truniger, based on the nickname of the group’s founder and organizer — Truniger.

The FBI/CISA report says Truniger previously operated as an affiliate of GandCrab, an early ransomware-as-a-service offering that closed up shop after several years and claims to have extorted more than $2 billion from victims. GandCrab dissolved in July 2019, and is thought to have become “REvil,” one of the most ruthless and rapacious Russian ransomware groups of all time.

The government says Snatch used a customized ransomware variant notable for rebooting Microsoft Windows devices into Safe Mode — enabling the ransomware to circumvent detection by antivirus or endpoint protection — and then encrypting files when few services are running.

“Snatch threat actors have been observed purchasing previously stolen data from other ransomware variants in an attempt to further exploit victims into paying a ransom to avoid having their data released on Snatch’s extortion blog,” the FBI/CISA alert reads. It continues:

“Prior to deploying the ransomware, Snatch threat actors were observed spending up to three months on a victim’s system. Within this timeframe, Snatch threat actors exploited the victim’s network moving laterally across the victim’s network with RDP for the largest possible deployment of ransomware and searching for files and folders for data exfiltration followed by file encryption.”

New York City-based cyber intelligence firm Flashpoint said the Snatch ransomware group was created in 2018, based on Truniger’s recruitment both on Russian language cybercrime forums and public Russian programming boards. Flashpoint said Truniger recruited “pen testers” for a new, then-unnamed cybercrime group, by posting their private Jabber instant messenger contact details on multiple Russian language coding forums, as well as on Facebook.

“The command requires Windows system administrators,” Truniger’s ads explained. “Experience in backup, increase privileges, mikicatz, network. Details after contacting on jabber: truniger@xmpp[.]jp.”

In at least some of those recruitment ads — like one in 2018 on the forum sysadmins[.]ru –the username promoting Truniger’s contact information was Semen7907. In April 2020, Truniger was banned from two of the top Russian cybercrime forums, where members from both forums confirmed that Semen7907 was one of Truniger’s known aliases.

[SIDE NOTE: Truniger was banned because he purchased credentials to a company from a network access broker on the dark web, and although he promised to share a certain percentage of whatever ransom amount Truniger’s group extracted from the victim, Truniger paid the access broker just a few hundred dollars off of a six-figure ransom].

According to Constella Intelligence, a data breach and threat actor research platform, a user named Semen7907 registered in 2017 on the Russian-language programming forum pawno[.]ru using the email address tretyakov-files@yandex.ru.

That same email address was assigned to the user “Semen-7907” on the now defunct gaming website tunngle.net, which suffered a data breach in 2020. Semen-7907 registered at Tunngle from the Internet address 31.192.175[.]63, which is in Yekaterinburg, RU.

Constella reports that tretyakov-files@yandex.ru was also used to register an account at the online game stalker[.]so with the nickname Trojan7907.

There is a Skype user by the handle semen7907, and which has the name Semyon Tretyakov from Yekaterinburg, RU. Constella also found a breached record from the Russian mobile telephony site tele2[.]ru, which shows that a user from Yekaterinburg registered in 2019 with the name Semyon Sergeyvich Tretyakov and email address tretyakov-files@ya.ru.

The above accounts, as well as the email address semen_7907@mail.ru, were all registered or accessed from the same Yekaterinburg Internet address mentioned previously: 31.192.175.63. The Russian mobile phone number associated with that tele2[.]ru account is connected to the Telegram account “Perchatka,” (“glove” in Russian).

BAD BEATS

Reached via Telegram, Perchatka (a.k.a. Mr. Tretyakov) said he was not a cybercriminal, and that he currently has a full-time job working in IT at a major company (he declined to specify which).

Presented with the information gathered for this report (and more that is not published here), Mr. Tretyakov acknowledged that Semen7907 was his account on sysadmins[.]ru, the very same account Truniger used to recruit hackers for the Snatch Ransomware group back in 2018.

However, he claims that he never made those posts, and that someone else must have assumed control over his sysadmins[.]ru account and posted as him. Mr. Tretyakov said that KrebsOnSecurity’s outreach this week was the first time he became aware that his sysadmins[.]ru account was used without his permission.

Mr. Tretyakov suggested someone may have framed him, pointing to an August 2023 story at a Russian news outlet about the reported hack and leak of the user database from sysadmins[.]ru, allegedly at the hands of a pro-Ukrainian hacker group called CyberSec.

“Recently, because of the war in Ukraine, a huge number of databases have been leaked and finding information about a person is not difficult,” Tretyakov said. “I’ve been using this login since about 2013 on all the forums where I register, and I don’t always set a strong password. If I had done something illegal, I would have hidden much better :D.”

[For the record, KrebsOnSecurity does not generally find this to be the case, as the ongoing Breadcrumbs series will attest.]

A Semyon Sergeyvich Tretyakov is listed as the composer of a Russian-language rap song called “Parallels,” which seems to be about the pursuit of a high-risk lifestyle online. A snippet of the song goes:

“Someone is on the screen, someone is on the blacklist
I turn on the timer and calculate the risks
I don’t want to stay broke And in the pursuit of money
I can’t take these zeros Life is like a zebra –
everyone wants to be first Either the stripes are white,
or we’re moving through the wilds I won’t waste time.”

Mr. Tretyakov said he was not the author of that particular rhyme, but that he has been known to record his own rhythms.

“Sometimes I make bad beats,” he said. “Soundcloud.”

NEVER MIND THE DOMAIN NAME

The FBI/CISA alert on Snatch Ransomware (PDF) includes an interesting caveat: It says Snatch actually deploys ransomware on victim systems, but it also acknowledges that the current occupants of Snatch’s dark and clear web domains call themselves Snatch Team, and maintain that they are not the same people as Snatch Ransomware from 2018.

Here’s the interesting bit from the FBI/CISA report:

“Since November 2021, an extortion site operating under the name Snatch served as a clearinghouse for data exfiltrated or stolen from victim companies on Clearnet and TOR hosted by a bulletproof hosting service. In August 2023, individuals claiming to be associated with the blog gave a media interview claiming the blog was not associated with Snatch ransomware and “none of our targets has been attacked by Ransomware Snatch…”, despite multiple confirmed Snatch victims’ data appearing on the blog alongside victims associated with other ransomware groups, notably Nokoyawa and Conti.”

Avid readers will recall a story here earlier this week about Snatch Team’s leaky darknet website based in Yekaterinburg, RU that exposed their internal operations and Internet addresses of their visitors. The leaked data suggest that Snatch is one of several ransomware groups using paid ads on Google.com to trick people into installing malware disguised as popular free software, such as Microsoft TeamsAdobe ReaderMozilla Thunderbird, and Discord.

Snatch Team claims to deal only in stolen data — not in deploying ransomware malware to hold systems hostage.

Representatives of the Snatch Team recently answered questions from Databreaches.net about the claimed discrepancy in the FBI/CISA report.

“First of all, we repeat once again that we have nothing to do with Snatch Ransomware, we are Security Notification Attachment, and we have never violated the terms of the concluded transactions, because our honesty and openness is the guarantee of our income,” the Snatch Team wrote to Databreaches.net in response to questions.

But so far the Snatch Team has not been able to explain why it is using the very same domain names that the Snatch ransomware group used?

Their claim is even more unbelievable because the Snatch Team members told Databreaches.net they didn’t even know that a ransomware group with that name already existed when they initially formed just two years ago.

This is difficult to swallow because even if they were a separate group, they’d still need to somehow coordinate the transfer of the Ransomware group’s domains on the clear and dark webs. If they were hoping for a fresh start or separation, why not just pick a new name and new web destination?

“Snatchteam[.]cc is essentially a data market,” they continued. “The only thing to underline is that we are against selling leaked information, sticking to the idea of free access. Absolutely any team can come to us and offer information for publication. Even more, we have heard rumors that a number of ransomware teams scare their clients that they will post leaked information on our resource. We do not have our own ransomware, but we are open to cooperation on placement and monetization of dates (sic).”

Maybe Snatch Team does not wish to be associated with Snatch Ransomware because they currently believe stealing data and then extorting victim companies for money is somehow less evil than infecting all of the victim’s servers and backups with ransomware.

It is also likely that Snatch Team is well aware of how poorly some of their founders covered their tracks online, and are hoping for a do-over on that front.

‘Snatch’ Ransom Group Exposes Visitor IP Addresses

By BrianKrebs

The victim shaming site operated by the Snatch ransomware group is leaking data about its true online location and internal operations, as well as the Internet addresses of its visitors, KrebsOnSecurity has found. The leaked data suggest that Snatch is one of several ransomware groups using paid ads on Google.com to trick people into installing malware disguised as popular free software, such as Microsoft Teams, Adobe Reader, Mozilla Thunderbird, and Discord.

First spotted in 2018, the Snatch ransomware group has published data stolen from hundreds of organizations that refused to pay a ransom demand. Snatch publishes its stolen data at a website on the open Internet, and that content is mirrored on the Snatch team’s darknet site, which is only reachable using the global anonymity network Tor.

The victim shaming website for the Snatch ransomware gang.

KrebsOnSecurity has learned that Snatch’s darknet site exposes its “server status” page, which includes information about the true Internet addresses of users accessing the website.

Refreshing this page every few seconds shows that the Snatch darknet site generates a decent amount of traffic, often attracting thousands of visitors each day. But by far the most frequent repeat visitors are coming from Internet addresses in Russia that either currently host Snatch’s clear web domain names or recently did.

The Snatch ransomware gang’s victim shaming site on the darknet is leaking data about its visitors. This “server status” page says that Snatch’s website is on Central European Summer Time (CEST) and is powered by OpenSSL/1.1.1f, which is no longer supported by security updates.

Probably the most active Internet address accessing Snatch’s darknet site is 193.108.114[.]41, which is a server in Yekaterinburg, Russia that hosts several Snatch domains, including snatchteam[.]top, sntech2ch[.]top, dwhyj2[.]top and sn76930193ch[.]top. It could well be that this Internet address is showing up frequently because Snatch’s clear-web site features a toggle button at the top that lets visitors switch over to accessing the site via Tor.

Another Internet address that showed up frequently in the Snatch server status page was 194.168.175[.]226, currently assigned to Matrix Telekom in Russia. According to DomainTools.com, this address also hosts or else recently hosted the usual coterie of Snatch domains, as well as quite a few domains phishing known brands such as Amazon and Cashapp.

The Moscow Internet address 80.66.64[.]15 accessed the Snatch darknet site all day long, and that address also housed the appropriate Snatch clear-web domains. More interestingly, that address is home to multiple recent domains that appear confusingly similar to known software companies, including libreoff1ce[.]com and www-discord[.]com.

This is interesting because the phishing domains associated with the Snatch ransomware gang were all registered to the same Russian name — Mihail Kolesnikov, a name that is somewhat synonymous with recent phishing domains tied to malicious Google ads.

Kolesnikov could be a nod to a Russian general made famous during Boris Yeltsin’s reign. Either way, it’s clearly a pseudonym, but there are some other commonalities among these domains that may provide insight into how Snatch and other ransomware groups are sourcing their victims.

DomainTools says there are more than 1,300 current and former domain names registered to Mihail Kolesnikov between 2013 and July 2023. About half of the domains appear to be older websites advertising female escort services in major cities around the United States (e.g. the now-defunct pittsburghcitygirls[.]com).

The other half of the Kolesnikov websites are far more recent phishing domains mostly ending in “.top” and “.app” that appear designed to mimic the domains of major software companies, including www-citrix[.]top, www-microsofteams[.]top, www-fortinet[.]top, ibreoffice[.]top, www-docker[.]top, www-basecamp[.]top, ccleaner-cdn[.]top, adobeusa[.]top, and www.real-vnc[.]top.

In August 2023, researchers with Trustwave Spiderlabs said they encountered domains registered to Mihail Kolesnikov being used to disseminate the Rilide information stealer trojan.

But it appears multiple crime groups may be using these domains to phish people and disseminate all kinds of information-stealing malware. In February 2023, Spamhaus warned of a huge surge in malicious ads that were hijacking search results in Google.com, and being used to distribute at least five different families of information stealing trojans, including AuroraStealer, IcedID/Bokbot, Meta Stealer, RedLine Stealer and Vidar.

For example, Spamhaus said victims of these malicious ads would search for Microsoft Teams in Google.com, and the search engine would often return a paid ad spoofing Microsoft or Microsoft Teams as the first result — above all other results. The malicious ad would include a logo for Microsoft and at first glance appear to be a safe and trusted place to download the Microsoft Teams client.

However, anyone who clicked on the result was whisked away instead to mlcrosofteams-us[.]top — yet another malicious domain registered to Mr. Kolesnikov. And while visitors to this website may believe they are only downloading the Microsoft Teams client, the installer file includes a copy of the IcedID malware, which is really good at stealing passwords and authentication tokens from the victim’s web browser.

Image: Spamhaus

The founder of the Swiss anti-abuse website abuse.ch told Spamhaus it is likely that some cybercriminals have started to sell “malvertising as a service” on the dark web, and that there is a great deal of demand for this service.

In other words, someone appears to have built a very profitable business churning out and promoting new software-themed phishing domains and selling that as a service to other cybercriminals. Or perhaps they are simply selling any stolen data (and any corporate access) to active and hungry ransomware group affiliates.

The tip about the exposed “server status” page on the Snatch darkweb site came from @htmalgae, the same security researcher who alerted KrebsOnSecurity earlier this month that the darknet victim shaming site run by the 8Base ransomware gang was inadvertently left in development mode.

That oversight revealed not only the true Internet address of the hidden 8Base site (in Russia, naturally), but also the identity of a programmer in Moldova who apparently helped to develop the 8Base code.

@htmalgae said the idea of a ransomware group’s victim shaming site leaking data that they did not intend to expose is deliciously ironic.

“This is a criminal group that shames others for not protecting user data,” @htmalgae said. “And here they are leaking their user data.”

All of the malware mentioned in this story is designed to run on Microsoft Windows devices. But Malwarebytes recently covered the emergence of a Mac-based information stealer trojan called AtomicStealer that was being advertised through malicious Google ads and domains that were confusingly similar to software brands.

Please be extra careful when you are searching online for popular software titles. Cracked, pirated copies of major software titles are a frequent source of infostealer infections, as are these rogue ads masquerading as search results. Make sure to double-check you are actually at the domain you believe you’re visiting *before* you download and install anything.

Stay tuned for Part II of this post, which includes a closer look at the Snatch ransomware group and their founder.

Chromium’s Impact on Root DNS Traffic

By Duane Wessels
Search Bar

This article originally appeared Aug. 21, 2020 on the APNIC blog.

Introduction

Chromium is an open-source software project that forms the foundation for Google’s Chrome web browser, as well as a number of other browser products, including Microsoft Edge, Opera, Amazon Silk, and Brave. Since Chrome’s introduction in 2008, Chromium-based browsers have steadily risen in popularity and today comprise approximately 70% of the market share.1

Chromium has, since its early days, included a feature known as the omnibox. This is where users may enter either a web site name, URL, or search terms. But the omnibox has an interface challenge. The user might enter a word like “marketing” that could refer to both an (intranet) web site and a search term. Which should the browser choose to display? Chromium treats it as a search term, but also displays an infobar that says something like “did you mean http://marketing/?” if a background DNS lookup for the name results in an IP address.

At this point, a new issue arises. Some networks (e.g., ISPs) utilize products or services designed to intercept and capture traffic from mistyped domain names. This is sometimes known as “NXDomain hijacking.” Users on such networks might be shown the “did you mean” infobar on every single-term search. To work around this, Chromium needs to know if it can trust the network to provide non-intercepted DNS responses.

Chromium Probe Design

Inside the Chromium source code there is a file named intranet_redirect_detector.c. The functions in this file attempt to load three URLs whose hostnames consist of a randomly generated single-label domain name, as shown in Figure 1 below.

Figure 1: Chromium source code that implements random URL fetches.
Figure 1: Chromium source code that implements random URL fetches.

This code results in three URL fetches, such as http://rociwefoie/, http://uawfkfrefre/, and http://awoimveroi/, and these in turn result in three DNS lookups for the random host names. As can be deduced from the source code, these random names are 7-15 characters in length (line 151) and consist of only the letters a-z (line 153). In versions of the code prior to February 2014, the random names were always 10 characters in length.

The intranet redirect detector functions are executed each time the browser starts up, each time the system/device’s IP address changes, and each time the system/device’s DNS configuration changes. If any two of these fetches resolve to the same address, that address is stored as the browser’s redirect origin.

Identifying Chromium Queries

Nearly any cursory glance at root name server traffic will exhibit queries for names that look like those used in Chromium’s probe queries. For example, here are 20 sequential queries received at an a.root-servers.net instance:

20 sequential queries received at an a.root-servers.net

In this brief snippet of data, we can see six queries (yellow highlight) for random, single-label names, and another four (green highlight) with random first labels followed by an apparent domain search suffix. These match the pattern from the Chromium source code, being 7-15 characters in length and consisting of only the letters a-z.

To characterize the amount of Chromium probe traffic in larger amounts of data (i.e., covering a 24-hour period), we tabulate queries based on the following attributes:

  • Response code (NXDomain or NoError)
  • Popularity of the leftmost label
  • Length of the leftmost label
  • Characters used in the leftmost label
  • Number of labels in the full query name
Sankey graph showing classification of queries matching Chromium probe patterns.
Figure 2: Sankey graph showing classification of queries matching Chromium probe patterns.

Figure 2 shows a classification of data from a.root-servers.net on May 13, 2020. Here we can see that 51% of all queried names were observed fewer than four times in the 24-hour period. Of those, nearly all were for non-existent TLDs, although a very small amount come from the existing TLDs (labeled “YXD” on the left). This small sliver represents either false positives or Chromium probe queries that have been subject to domain suffix search appending by stub resolvers or end user applications.

Of the 51% observed fewer than four times, all but 2.86% of those have a first label between 7 and 15 characters in length (inclusive). Furthermore, most of those match the pattern consisting of only a-z characters (case insensitive), leaving us with 45.80% of total traffic on this day that appears to be from Chromium probes.

From there we break down the queries by number of labels and length of the first label. Note that label lengths, on the far right of the graph, have a very even distribution, except for 7 and 10 characters. Labels with 10 characters are more popular because older versions of Chromium generated only 10-character names. We believe that 7 is less popular due to the increased probability of collisions in only 7 characters, which can increase the query count to above our threshold of three.

Longitudinal Analysis

Next, we turn our attention to an analysis of how the total root traffic percentage of Chromium-like queries has changed over time. We use two data sets in this analysis: data from DNS-OARC’s “Day In The Life” (DITL) collections, and Verisign’s data for a.root-servers.net and j.root-servers.net.

Long-term trend analysis of Chromium-like queries to root name servers.
Figure 3: Long-term trend analysis of Chromium-like queries to root name servers.

Figure 3 shows the results of the long-term analysis. We were able to analyze the annual DITL data from 2006-2014, and from 2017-2018, labeled “DITL Full” in the figure. The 2015-2016 data was unavailable on the DNS-OARC systems. The 2019 dataset could not be analyzed in full due to its size, so we settled for a sampled analysis instead, labeled “DITL Sampled” in Figure 3. The 2020 data was not ready for analysis by the time our research was done.

In every DITL dataset, we analyzed each root server identity (“letter”) separately. This produces a range of values for each year. The solid line shows the average of all the identities, while the shaded area shows the range of values.

To fill in some of the DITL gaps we used Verisign’s own data for a.root-servers.net and j.root-servers.net. Here we selected a 24-hour period for each month. Again, the solid line shows the average and the shaded area represents the range.

The figure also includes a line labeled “Chrome market share” (note: Chrome, not Chromium-based browsers) and a marker indicating when the feature was first added to the source code. Note, there are some false positive Chromium-like queries observed in the DITL data prior to introduction of the feature, comprising about 1% of the total traffic, but in the 10+ years since the feature was added, we now find that half of the DNS root server traffic is very likely due to Chromium’s probes. That equates to about 60 billion queries to the root server system on a typical day.

Concluding Thoughts

The root server system is, out of necessity, designed to handle very large amounts of traffic. As we have shown here, under normal operating conditions, half of the traffic originates with a single library function, on a single browser platform, whose sole purpose is to detect DNS interception. Such interception is certainly the exception rather than the norm. In almost any other scenario, this traffic would be indistinguishable from a distributed denial of service (DDoS) attack.

Could Chromium achieve its goal while only sending one or two queries instead of three? Are other approaches feasible? For example, Firefox’s captive portal test uses delegated namespace probe queries, directing them away from the root servers towards the browser’s own infrastructure. While technical solutions such as Aggressive NSEC Caching (RFC 8198), Qname Minimization (RFC 7816), and NXDomain Cut (RFC 8020) could also significantly reduce probe queries to the root server system, these solutions require action by recursive resolver operators, who have limited incentive to deploy and support these technologies.

Who’s Behind the 8Base Ransomware Website?

By BrianKrebs

The victim shaming website operated by the cybercriminals behind 8Base — currently one of the more active ransomware groups — was until earlier today leaking quite a bit of information that the crime group probably did not intend to be made public. The leaked data suggests that at least some of website’s code was written by a 36-year-old programmer residing in the capital city of Moldova.

The 8Base ransomware group’s victim shaming website on the darknet.

8Base maintains a darknet website that is only reachable via Tor, a freely available global anonymity network. The site lists hundreds of victim organizations and companies — all allegedly hacking victims that refused to pay a ransom to keep their stolen data from being published.

The 8Base darknet site also has a built-in chat feature, presumably so that 8Base victims can communicate and negotiate with their extortionists. This chat feature, which runs on the Laravel web application framework, works fine as long as you are *sending* information to the site (i.e., by making a “POST” request).

However, if one were to try to fetch data from the same chat service (i.e., by making a “GET” request), the website until quite recently generated an extremely verbose error message:

The verbose error message when one tries to pull data from 8Base’s darknet site. Notice the link at the bottom of this image, which is generated when one hovers over the “View commit” message under the “Git” heading.

That error page revealed the true Internet address of the Tor hidden service that houses the 8Base website: 95.216.51[.]74, which according to DomainTools.com is a server in Finland that is tied to the Germany-based hosting giant Hetzner.

But that’s not the interesting part: Scrolling down the lengthy error message, we can see a link to a private Gitlab server called Jcube-group: gitlab[.]com/jcube-group/clients/apex/8base-v2. Digging further into this Gitlab account, we can find some curious data points available in the JCube Group’s public code repository.

For example, this “status.php” page, which was committed to JCube Group’s Gitlab repository roughly one month ago, includes code that makes several mentions of the term “KYC” (e.g. KYC_UNVERIFIED, KYC_VERIFIED, and KYC_PENDING).

This is curious because a FAQ on the 8Base darknet site includes a section on “special offers for journalists and reporters,” which says the crime group is open to interviews but that journalists will need to prove their identity before any interview can take place. The 8base FAQ refers to this vetting process as “KYC,” which typically stands for “Know Your Customer.”

“We highly respect the work of journalists and consider information to be our priority,” the 8Base FAQ reads. “We have a special program for journalists which includes sharing information a few hours or even days before it is officially published on our news website and Telegram channel: you would need to go through a KYC procedure to apply. Journalists and reporters can contact us via our PR Telegram channel with any questions.”

The 8Base FAQ (left) and the KYC code in Kolev’s Gitlab account (right)

The 8Base darknet site also has a publicly accessible “admin” login page, which features an image of a commercial passenger plane parked at what appears to be an airport. Next to the airplane photo is a message that reads, “Welcome to 8Base. Admin Login to 8Base dashboard.”

The login page on the 8Base ransomware group’s darknet website.

Right-clicking on the 8Base admin page and selecting “View Source” produces the page’s HTML code. That code is virtually identical to a “login.blade.php” page that was authored and committed to JCube Group’s Gitlab repository roughly three weeks ago.

It appears the person responsible for the JCube Group’s code is a 36-year-old developer from Chisinau, Moldova named Andrei Kolev. Mr. Kolev’s LinkedIn page says he’s a full-stack developer at JCube Group, and that he’s currently looking for work. The homepage for Jcubegroup[.]com lists an address and phone number that Moldovan business records confirm is tied to Mr. Kolev.

The posts on the Twitter account for Mr. Kolev (@andrewkolev) are all written in Russian, and reference several now-defunct online businesses, including pluginspro[.]ru.

Reached for comment via LinkedIn, Mr. Kolev said he had no idea why the 8Base darknet site was pulling code from the “clients” directory of his private JCube Group Gitlab repository, or how the 8Base name was even included.

“I [don’t have] a clue, I don’t have that project in my repo,” Kolev explained. “They [aren’t] my clients. Actually we currently have just our own projects.”

Mr. Kolev shared a screenshot of his current projects, but very quickly after that deleted it. However, KrebsOnSecurity captured a copy of the image before it was removed:

A screenshot of Mr. Kolev’s current projects that he quickly deleted.

Within minutes of explaining why I was reaching out to Mr. Kolev and walking him through the process of finding this connection, the 8Base website was changed, and the error message that linked to the JCube Group private Gitlab repository no longer appeared. Instead, trying the same “GET” method described above caused the 8Base website to return a “405 Method Not Allowed” error page:

Mr. Kolev claimed he didn’t know anything about the now-removed error page on 8Base’s site that referenced his private Gitlab repo, and said he deleted the screenshot from our LinkedIn chat because it contained private information.

Ransomware groups are known to remotely hire developers for specific projects without disclosing exactly who they are or how the new hire’s code is intended to be used, and it is possible that one of Mr. Kolev’s clients is merely a front for 8Base. But despite 8Base’s statement that they are happy to correspond with journalists, KrebsOnSecurity is still waiting for a reply from the group via their Telegram channel.

The tip about the leaky 8Base website was provided by a reader who asked to remain anonymous. That reader, a legitimate security professional and researcher who goes by the handle @htmalgae on Twitter, said it is likely that whoever developed the 8Base website inadvertently left it in “development mode,” which is what caused the site to be so verbose with its error messages.

“If 8Base was running the app in production mode instead of development mode, this Tor de-anonymization would have never been possible,” @htmalgae said.

A recent blog post from VMware/Carbon Black called the 8Base ransomware group “a heavy hitter” that has remained relatively unknown despite the massive spike in activity in Summer of 2023.

“8Base is a Ransomware group that has been active since March 2022 with a significant spike in activity in June of 2023,” Carbon Black researchers wrote. “Describing themselves as ‘simple pen testers,’ their leak site provided victim details through Frequently Asked Questions and Rules sections as well as multiple ways to contact them. ”

According to VMware, what’s particularly interesting about 8Base’s communication style is the use of verbiage that is strikingly familiar to another known cybercriminal group: RansomHouse.

“The group utilizes encryption paired with ‘name-and-shame’ techniques to compel their victims to pay their ransoms,” VMware researchers wrote. “8Base has an opportunistic pattern of compromise with recent victims spanning across varied industries. Despite the high amount of compromises, the information regarding identities, methodology, and underlying motivation behind these incidents still remains a mystery.”

Update, Sept. 21, 10:43 a.m. ET: The author of Databreaches.net was lurking in the 8Base Telegram channel when I popped in to ask the crime group a question, and reports that 8Base did eventually reply: ““hi at the moment we r not doing interviews. we have nothing to say. we r a little busy.”

FBI Hacker Dropped Stolen Airbus Data on 9/11

By BrianKrebs

In December 2022, KrebsOnSecurity broke the news that a cybercriminal using the handle “USDoD” had infiltrated the FBI‘s vetted information sharing network InfraGard, and was selling the contact information for all 80,000 members. The FBI responded by reverifying InfraGard members and by seizing the cybercrime forum where the data was being sold. But on Sept. 11, 2023, USDoD resurfaced after a lengthy absence to leak sensitive employee data stolen from the aerospace giant Airbus, while promising to visit the same treatment on top U.S. defense contractors.

USDoD’s avatar used to be the seal of the U.S. Department of Defense. Now it’s a charming kitten.

In a post on the English language cybercrime forum BreachForums, USDoD leaked information on roughly 3,200 Airbus vendors, including names, addresses, phone numbers, and email addresses. USDoD claimed they grabbed the data by using passwords stolen from a Turkish airline employee who had third-party access to Airbus’ systems.

USDoD didn’t say why they decided to leak the data on the 22nd anniversary of the 9/11 attacks, but there was definitely an aircraft theme to the message that accompanied the leak, which concluded with the words, “Lockheed martin, Raytheon and the entire defense contractos [sic], I’m coming for you [expletive].”

Airbus has apparently confirmed the cybercriminal’s account to the threat intelligence firm Hudson Rock, which determined that the Airbus credentials were stolen after a Turkish airline employee infected their computer with a prevalent and powerful info-stealing trojan called RedLine.

Info-stealers like RedLine typically are deployed via opportunistic email malware campaigns, and by secretly bundling the trojans with cracked versions of popular software titles made available online. Credentials stolen by info-stealers often end up for sale on cybercrime shops that peddle purloined passwords and authentication cookies (these logs also often show up in the malware scanning service VirusTotal).

Hudson Rock said it recovered the log files created by a RedLine infection on the Turkish airline employee’s system, and found the employee likely infected their machine after downloading pirated and secretly backdoored software for Microsoft Windows.

Hudson Rock says info-stealer infections from RedLine and a host of similar trojans have surged in recent years, and that they remain “a primary initial attack vector used by threat actors to infiltrate organizations and execute cyberattacks, including ransomware, data breaches, account overtakes, and corporate espionage.”

The prevalence of RedLine and other info-stealers means that a great many consequential security breaches begin with cybercriminals abusing stolen employee credentials. In this scenario, the attacker temporarily assumes the identity and online privileges assigned to a hacked employee, and the onus is on the employer to tell the difference.

In addition to snarfing any passwords stored on or transmitted through an infected system, info-stealers also siphon authentication cookies or tokens that allow one to remain signed-in to online services for long periods of time without having to resupply one’s password and multi-factor authentication code. By stealing these tokens, attackers can often reuse them in their own web browser, and bypass any authentication normally required for that account.

Microsoft Corp. this week acknowledged that a China-backed hacking group was able to steal one of the keys to its email kingdom that granted near-unfettered access to U.S. government inboxes. Microsoft’s detailed post-mortem cum mea culpa explained that a secret signing key was stolen from an employee in an unlucky series of unfortunate events, and thanks to TechCrunch we now know that the culprit once again was “token-stealing malware” on the employee’s system.

In April 2023, the FBI seized Genesis Market, a bustling, fully automated cybercrime store that was continuously restocked with freshly hacked passwords and authentication tokens stolen by a network of contractors who deployed RedLine and other info-stealer malware.

In March 2023, the FBI arrested and charged the alleged administrator of BreachForums (aka Breached), the same cybercrime community where USDoD leaked the Airbus data. In June 2023, the FBI seized the BreachForums domain name, but the forum has since migrated to a new domain.

USDoD’s InfraGard sales thread on Breached.

Unsolicited email continues to be a huge vector for info-stealing malware, but lately the crooks behind these schemes have been gaming the search engines so that their malicious sites impersonating popular software vendors actually appear before the legitimate vendor’s website. So take special care when downloading software to ensure that you are in fact getting the program from the original, legitimate source whenever possible.

Also, unless you really know what you’re doing, please don’t download and install pirated software. Sure, the cracked program might do exactly what you expect it to do, but the chances are good that it is also laced with something nasty. And when all of your passwords are stolen and your important accounts have been hijacked or sold, you will wish you had simply paid for the real thing.

Adobe, Apple, Google & Microsoft Patch 0-Day Bugs

By BrianKrebs

Microsoft today issued software updates to fix at least five dozen security holes in Windows and supported software, including patches for two zero-day vulnerabilities that are already being exploited. Also, Adobe, Google Chrome and Apple iOS users may have their own zero-day patching to do.

On Sept. 7, researchers at Citizen Lab warned they were seeing active exploitation of a “zero-click,” zero-day flaw to install spyware on iOS devices without any interaction from the victim.

“The exploit chain was capable of compromising iPhones running the latest version of iOS (16.6) without any interaction from the victim,” the researchers wrote.

According to Citizen Lab, the exploit uses malicious images sent via iMessage, an embedded component of Apple’s iOS that has been the source of previous zero-click flaws in iPhones and iPads.

Apple says the iOS flaw (CVE-2023-41064) does not seem to work against devices that have its ultra-paranoid “Lockdown Mode” enabled. This feature restricts non-essential iOS features to reduce the device’s overall attack surface, and it was designed for users concerned that they may be subject to targeted attacks. Citizen Lab says the bug it discovered was being exploited to install spyware made by the Israeli cyber surveillance company NSO Group.

This vulnerability is fixed in iOS 16.6.1 and iPadOS 16.6.1. To turn on Lockdown Mode in iOS 16, go to Settings, then Privacy and Security, then Lockdown Mode.

Not to be left out of the zero-day fun, Google acknowledged on Sept. 11 that an exploit for a heap overflow bug in Chrome is being exploited in the wild. Google says it is releasing updates to fix the flaw, and that restarting Chrome is the way to apply any pending updates. Interestingly, Google says this bug was reported by Apple and Citizen Lab.

On the Microsoft front, a zero-day in Microsoft Word is among the more concerning bugs fixed today. Tracked as CVE-2023-36761, it is flagged as an “information disclosure” vulnerability. But that description hardly grasps at the sensitivity of the information potentially exposed here.

Tom Bowyer, manager of product security at Automox, said exploiting this vulnerability could lead to the disclosure of Net-NTLMv2 hashes, which are used for authentication in Windows environments.

“If a malicious actor gains access to these hashes, they can potentially impersonate the user, gaining unauthorized access to sensitive data and systems,” Bowyer said, noting that CVE-2023-36761 can be exploited just by viewing a malicious document in the Windows preview pane. “They could also conduct pass-the-hash attacks, where the attacker uses the hashed version of a password to authenticate themselves without needing to decrypt it.”

The other Windows zero-day fixed this month is CVE-2023-36802. This is an “elevation of privilege” flaw in the “Microsoft Streaming Service Proxy,” which is built into Windows 10, 11 and Windows Server versions. Microsoft says an attacker who successfully exploits the bug can gain SYSTEM level privileges on a Windows computer.

Five of the flaws Microsoft fixed this month earned its “critical” rating, which the software giant reserves for vulnerabilities that can be exploited by malware or malcontents with little or no interaction by Windows users.

According to the SANS Internet Storm Center, the most serious critical bug in September’s Patch Tuesday is CVE-2023-38148, which is a weakness in the Internet Connection Sharing service on Windows. Microsoft says an unauthenticated attacker could leverage the flaw to install malware just sending a specially crafted data packet to a vulnerable Windows system.

Finally, Adobe has released critical security updates for its Adobe Reader and Acrobat software that also fixes a zero-day vulnerability (CVE-2023-26369). More details are at Adobe’s advisory.

For a more granular breakdown of the Windows updates pushed out today, check out Microsoft Patch Tuesday by Morphus Labs. In the meantime, consider backing up your data before updating Windows, and keep an eye on AskWoody.com for reports of any widespread problems with any of the updates released as part of September’s Patch Tuesday.

Update: Mozilla also has fixed zero-day flaw in Firefox and Thunderbird, and the Brave browser was updated as well. It appears the common theme here is any software that uses a code library called “libwebp,” and that this vulnerability is being tracked as CVE-2023-4863.

“This includes Electron-based applications, for example – Signal,” writes StackDiary.com. “Electron patched the vulnerability yesterday. Also, software like Honeyview (from Bandisoft) released an update to fix the issue. CVE-2023-4863 was falsely marked as Chrome-only by Mitre and other organizations that track CVE’s and 100% of media reported this issue as “Chrome only”, when it’s not.”

U.S. Hacks QakBot, Quietly Removes Botnet Infections

By BrianKrebs

The U.S. government today announced a coordinated crackdown against QakBot, a complex malware family used by multiple cybercrime groups to lay the groundwork for ransomware infections. The international law enforcement operation involved seizing control over the botnet’s online infrastructure, and quietly removing the Qakbot malware from tens of thousands of infected Microsoft Windows computers.

In an international operation announced today dubbed “Duck Hunt,” the U.S. Department of Justice (DOJ) and Federal Bureau of Investigation (FBI) said they obtained court orders to remove Qakbot from infected devices, and to seize servers used to control the botnet.

“This is the most significant technological and financial operation ever led by the Department of Justice against a botnet,” said Martin Estrada, the U.S. attorney for the Southern District of California, at a press conference this morning in Los Angeles.

Estrada said Qakbot has been implicated in 40 different ransomware attacks over the past 18 months, intrusions that collectively cost victims more than $58 million in losses.

Emerging in 2007 as a banking trojan, QakBot (a.k.a. Qbot and Pinkslipbot) has morphed into an advanced malware strain now used by multiple cybercriminal groups to prepare newly compromised networks for ransomware infestations. QakBot is most commonly delivered via email phishing lures disguised as something legitimate and time-sensitive, such as invoices or work orders.

Don Alway, assistant director in charge of the FBI’s Los Angeles field office, said federal investigators gained access to an online panel that allowed cybercrooks to monitor and control the actions of the botnet. From there, investigators obtained court-ordered approval to instruct all infected systems to uninstall Qakbot and to disconnect themselves from the botnet, Alway said.

The DOJ says their access to the botnet’s control panel revealed that Qakbot had been used to infect more than 700,000 machines in the past year alone, including 200,000 systems in the United States.

Working with law enforcement partners in France, Germany, Latvia, the Netherlands, Romania and the United Kingdom, the DOJ said it was able to seize more than 50 Internet servers tied to the malware network, and nearly $9 million in ill-gotten cryptocurrency from QakBot’s cybercriminal overlords. The DOJ declined to say whether any suspects were questioned or arrested in connection with Qakbot, citing an ongoing investigation.

According to recent figures from the managed security firm Reliaquest, QakBot is by far the most prevalent malware “loader” — malicious software used to secure access to a hacked network and help drop additional malware payloads. Reliaquest says QakBot infections accounted for nearly one-third of all loaders observed in the wild during the first six months of this year.

Qakbot/Qbot was once again the top malware loader observed in the wild in the first six months of 2023. Source: Reliaquest.com.

Researchers at AT&T Alien Labs say the crooks responsible for maintaining the QakBot botnet have rented their creation to various cybercrime groups over the years. More recently, however, QakBot has been closely associated with ransomware attacks from Black Basta, a prolific Russian-language criminal group that was thought to have spun off from the Conti ransomware gang in early 2022.

Today’s operation is not the first time the U.S. government has used court orders to remotely disinfect systems compromised with malware. In May 2023, the DOJ quietly removed malware from computers around the world infected by the “Snake” malware, an even older malware family that has been tied to Russian intelligence agencies.

Documents published by the DOJ in support of today’s takedown state that beginning on Aug. 25, 2023, law enforcement gained access to the Qakbot botnet, redirected botnet traffic to and through servers controlled by law enforcement, and instructed Qakbot-infected computers to download a Qakbot Uninstall file that uninstalled Qakbot malware from the infected computer.

“The Qakbot Uninstall file did not remediate other malware that was already installed on infected computers,” the government explained. “Instead, it was designed to prevent additional Qakbot malware from being installed on the infected computer by untethering the victim computer from the Qakbot botnet.”

The DOJ said it also recovered more than 6.5 million stolen passwords and other credentials, and that it has shared this information with two websites that let users check to see if their credentials were exposed: Have I Been Pwned, and a “Check Your Hack” website erected by the Dutch National Police.

Karma Catches Up to Global Phishing Service 16Shop

By BrianKrebs

You’ve probably never heard of “16Shop,” but there’s a good chance someone using it has tried to phish you.

A 16Shop phishing page spoofing Apple and targeting Japanese users. Image: Akamai.com.

The international police organization INTERPOL said last week it had shuttered the notorious 16Shop, a popular phishing-as-a-service platform launched in 2017 that made it simple for even complete novices to conduct complex and convincing phishing scams. INTERPOL said authorities in Indonesia arrested the 21-year-old proprietor and one of his alleged facilitators, and that a third suspect was apprehended in Japan.

The INTERPOL statement says the platform sold hacking tools to compromise more than 70,000 users in 43 countries. Given how long 16Shop has been around and how many paying customers it enjoyed over the years, that number is almost certainly highly conservative.

Also, the sale of “hacking tools” doesn’t quite capture what 16Shop was all about: It was a fully automated phishing platform that gave its thousands of customers a series of brand-specific phishing kits to use, and provided the domain names needed to host the phishing pages and receive any stolen credentials.

Security experts investigating 16Shop found the service used an application programming interface (API) to manage its users, an innovation that allowed its proprietors to shut off access to customers who failed to pay a monthly fee, or for those attempting to copy or pirate the phishing kit.

16Shop also localized phishing pages in multiple languages, and the service would display relevant phishing content depending on the victim’s geolocation.

Various 16Shop lures for Apple users in different languages. Image: Akamai.

For example, in 2019 McAfee found that for targets in Japan, the 16Shop kit would also collect Web ID and Card Password, while US victims will be asked for their Social Security Number.

“Depending on location, 16Shop will also collect ID numbers (including Civil ID, National ID, and Citizen ID), passport numbers, social insurance numbers, sort codes, and credit limits,” McAfee wrote.

In addition, 16Shop employed various tricks to help its users’ phishing pages stay off the radar of security firms, including a local “blacklist” of Internet addresses tied to security companies, and a feature that allowed users to block entire Internet address ranges from accessing phishing pages.

The INTERPOL announcement does not name any of the suspects arrested in connection with the 16Shop investigation. However, a number of security firms — including Akamai, McAfee and ZeroFox, previously connected the service to a young Indonesian man named Riswanda Noor Saputra, who sold 16Shop under the hacker handle “Devilscream.”

According to the Indonesian security blog Cyberthreat.id, Saputra admitted being the administrator of 16Shop, but told the publication he handed the project off to others by early 2020.

Nevertheless, Cyberthreat reported that Devilscream was arrested by Indonesian police in late 2021 as part of a collaboration between INTERPOL and the U.S. Federal Bureau of Investigation (FBI). Still, researchers who tracked 16Shop since its inception say Devilscream was not the original proprietor of the phishing platform, and he may not be the last.

RIZKY BUSINESS

It is not uncommon for cybercriminals to accidentally infect their own machines with password-stealing malware, and that is exactly what seems to have happened with one of the more recent administrators of 16Shop.

Constella Intelligence, a data breach and threat actor research platform, now allows users to cross-reference popular cybercrime websites and denizens of these forums with inadvertent malware infections by information-stealing trojans. A search in Constella on 16Shop’s domain name shows that in mid-2022, a key administrator of the phishing service infected their Microsoft Windows desktop computer with the Redline information stealer trojan — apparently by downloading a cracked (and secretly backdoored) copy of Adobe Photoshop.

Redline infections steal gobs of data from the victim machine, including a list of recent downloads, stored passwords and authentication cookies, as well as browser bookmarks and auto-fill data. Those records indicate the 16Shop admin used the nicknames “Rudi” and “Rizki/Rizky,” and maintained several Facebook profiles under these monikers.

It appears this user’s full name (or at least part of it) is Rizky Mauluna Sidik, and they are from Bandung in West Java, Indonesia. One of this user’s Facebook pages says Rizky is the chief executive officer and founder of an entity called BandungXploiter, whose Facebook page indicates it is a group focused mainly on hacking and defacing websites.

A LinkedIn profile for Rizky says he is a backend Web developer in Bandung who earned a bachelor’s degree in information technology in 2020. Mr. Rizky did not respond to requests for comment.
