Late last year, security researchers made a startling discovery: Kremlin-backed disinformation campaigns were bypassing moderation on social media platforms by leveraging the same malicious advertising technology that powers a sprawling ecosystem of online hucksters and website hackers. A new report on the fallout from that investigation finds this dark ad tech industry is far more resilient and incestuous than previously known.

In November 2024, researchers at the security firm Qurium published an investigation into “Doppelganger,” a disinformation network that promotes pro-Russian narratives and infiltrates Europe’s media landscape by pushing fake news through a network of cloned websites.
Doppelganger campaigns use specialized links that bounce the visitor’s browser through a long series of domains before the fake news content is served. Qurium found Doppelganger relies on a sophisticated “domain cloaking” service, a technology that allows websites to present different content to search engines compared to what regular visitors see. The use of cloaking services helps the disinformation sites remain online longer than they otherwise would, while ensuring that only the targeted audience gets to view the intended content.
Qurium discovered that Doppelganger’s cloaking service also promoted online dating sites, and shared much of the same infrastructure with VexTrio, which is thought to be the oldest malicious traffic distribution system (TDS) in existence. While TDSs are commonly used by legitimate advertising networks to manage traffic from disparate sources and to track who or what is behind each click, VexTrio’s TDS largely manages web traffic from victims of phishing, malware, and social engineering scams.
Digging deeper, Qurium noticed Doppelganger’s cloaking service used an Internet provider in Switzerland as the first entry point in a chain of domain redirections. They also noticed the same infrastructure hosted a pair of co-branded affiliate marketing services that were driving traffic to sketchy adult dating sites: LosPollos[.]com and TacoLoco[.]co.
The LosPollos ad network incorporates many elements and references from the hit series “Breaking Bad,” mirroring the fictional “Los Pollos Hermanos” restaurant chain that served as a money laundering operation for a violent methamphetamine cartel.
The LosPollos advertising network invokes characters and themes from the hit show Breaking Bad. The logo for LosPollos (upper left) is the image of Gustavo Fring, the fictional chicken restaurant chain owner in the show.
Affiliates who sign up with LosPollos are given JavaScript-heavy “smartlinks” that drive traffic into the VexTrio TDS, which in turn distributes the traffic among a variety of advertising partners, including dating services, sweepstakes offers, bait-and-switch mobile apps, financial scams and malware download sites.
LosPollos affiliates typically stitch these smart links into WordPress websites that have been hacked via known vulnerabilities, and those affiliates will earn a small commission each time an Internet user referred by any of their hacked sites falls for one of these lures.

According to Qurium, TacoLoco is a traffic monetization network that uses deceptive tactics to trick Internet users into enabling “push notifications,” a cross-platform browser standard that allows websites to show pop-up messages which appear outside of the browser. For example, on Microsoft Windows systems these notifications typically show up in the bottom right corner of the screen — just above the system clock.
In the case of VexTrio and TacoLoco, the notification approval requests themselves are deceptive — disguised as “CAPTCHA” challenges designed to distinguish automated bot traffic from real visitors. For years, VexTrio and its partners have successfully tricked countless users into enabling these site notifications, which are then used to continuously pepper the victim’s device with a variety of phony virus alerts and misleading pop-up messages.
Examples of VexTrio landing pages that lead users to accept push notifications on their device.
According to a December 2024 annual report from GoDaddy, nearly 40 percent of compromised websites in 2024 redirected visitors to VexTrio via LosPollos smartlinks.
On November 14, 2024, Qurium published research to support its findings that LosPollos and TacoLoco were services operated by Adspro Group, a company registered in the Czech Republic and Russia, and that Adspro runs its infrastructure at the Swiss hosting providers C41 and Teknology SA.
Qurium noted the LosPollos and TacoLoco sites state that their content is copyrighted by ByteCore AG and SkyForge Digital AG, both Swiss firms that are run by the owner of Teknology SA, Giulio Vitorrio Leonardo Cerutti. Further investigation revealed LosPollos and TacoLoco were apps developed by a company called Holacode, which lists Cerutti as its CEO.
The apps marketed by Holacode include numerous VPN services, as well as one called Spamshield that claims to stop unwanted push notifications. But in January, Infoblox said they tested the app on their own mobile devices, and found it hides the user’s notifications, and then after 24 hours stops hiding them and demands payment. Spamshield subsequently changed its developer name from Holacode to ApLabz, although Infoblox noted that the Terms of Service for several of the rebranded ApLabz apps still referenced Holacode in their terms of service.
Incredibly, Cerutti threatened to sue me for defamation before I’d even uttered his name or sent him a request for comment (Cerutti sent the unsolicited legal threat back in January after his company and my name were merely tagged in an Infoblox post on LinkedIn about VexTrio).
Asked to comment on the findings by Qurium and Infoblox, Cerutti vehemently denied being associated with VexTrio. Cerutti asserted that his companies all strictly adhere to the regulations of the countries in which they operate, and that they have been completely transparent about all of their operations.
“We are a group operating in the advertising and marketing space, with an affiliate network program,” Cerutti responded. “I am not [going] to say we are perfect, but I strongly declare we have no connection with VexTrio at all.”
“Unfortunately, as a big player in this space we also get to deal with plenty of publisher fraud, sketchy traffic, fake clicks, bots, hacked, listed and resold publisher accounts, etc, etc.,” Cerutti continued. “We bleed lots of money to such malpractices and conduct regular internal screenings and audits in a constant battle to remove bad traffic sources. It is also a highly competitive space, where some upstarts will often play dirty against more established mainstream players like us.”
Working with Qurium, researchers at the security firm Infoblox released details about VexTrio’s infrastructure to their industry partners. Just four days after Qurium published its findings, LosPollos announced it was suspending its push monetization service. Less than a month later, Adspro had rebranded to Aimed Global.

In March 2025, researchers at GoDaddy chronicled how DollyWay — a malware strain that has consistently redirected victims to VexTrio throughout its eight years of activity — suddenly stopped doing that on November 20, 2024. Virtually overnight, DollyWay and several other malware families that had previously used VexTrio began pushing their traffic through another TDS called Help TDS.
Digging further into historical DNS records and the unique code scripts used by the Help TDS, Infoblox determined it has long enjoyed an exclusive relationship with VexTrio (at least until LosPollos ended its push monetization service in November).
In a report released today, Infoblox said an exhaustive analysis of the JavaScript code, website lures, smartlinks and DNS patterns used by VexTrio and Help TDS linked them with at least four other TDS operators (not counting TacoLoco). Those four entities — Partners House, BroPush, RichAds and RexPush — are all Russia-based push monetization programs that pay affiliates to drive signups for a variety of schemes, but mostly online dating services.
“As Los Pollos push monetization ended, we’ve seen an increase in fake CAPTCHAs that drive user acceptance of push notifications, particularly from Partners House,” the Infoblox report reads. “The relationship of these commercial entities remains a mystery; while they are certainly long-time partners redirecting traffic to one another, and they all have a Russian nexus, there is no overt common ownership.”
Renee Burton, vice president of threat intelligence at Infoblox, said the security industry generally treats the deceptive methods used by VexTrio and other malicious TDSs as a kind of legally grey area that is mostly associated with less dangerous security threats, such as adware and scareware.
But Burton argues that this view is myopic, and helps perpetuate a dark adtech industry that also pushes plenty of straight-up malware, noting that hundreds of thousands of compromised websites around the world every year redirect victims to the tangled web of VexTrio and VexTrio-affiliate TDSs.
“These TDSs are a nefarious threat, because they’re the ones you can connect to the delivery of things like information stealers and scams that cost consumers billions of dollars a year,” Burton said. “From a larger strategic perspective, my takeaway is that Russian organized crime has control of malicious adtech, and these are just some of the many groups involved.”
As KrebsOnSecurity warned way back in 2020, it’s a good idea to be very sparing in approving notifications when browsing the Web. In many cases these notifications are benign, but as we’ve seen there are numerous dodgy firms that are paying site owners to install their notification scripts, and then reselling that communications pathway to scammers and online hucksters.
If you’d like to prevent sites from ever presenting notification requests, all of the major browser makers let you do this — either across the board or on a per-website basis. While it is true that blocking notifications entirely can break the functionality of some websites, doing this for any devices you manage on behalf of your less tech-savvy friends or family members might end up saving everyone a lot of headache down the road.
To modify site notification settings in Mozilla Firefox, navigate to Settings, Privacy & Security, Permissions, and click the “Settings” tab next to “Notifications.” That page will display any notifications already permitted and allow you to edit or delete any entries. Tick the box next to “Block new requests asking to allow notifications” to stop them altogether.
In Google Chrome, click the icon with the three dots to the right of the address bar, scroll all the way down to Settings, Privacy and Security, Site Settings, and Notifications. Select the “Don’t allow sites to send notifications” button if you want to banish notification requests forever.
In Apple’s Safari browser, go to Settings, Websites, and click on Notifications in the sidebar. Uncheck the option to “allow websites to ask for permission to send notifications” if you wish to turn off notification requests entirely.

The U.S. government today imposed economic sanctions on Funnull Technology Inc., a Philippines-based company that provides computer infrastructure for hundreds of thousands of websites involved in virtual currency investment scams known as “pig butchering.” In January 2025, KrebsOnSecurity detailed how Funnull was being used as a content delivery network that catered to cybercriminals seeking to route their traffic through U.S.-based cloud providers.
“Americans lose billions of dollars annually to these cyber scams, with revenues generated from these crimes rising to record levels in 2024,” reads a statement from the U.S. Department of the Treasury, which sanctioned Funnull and its 40-year-old Chinese administrator Liu Lizhi. “Funnull has directly facilitated several of these schemes, resulting in over $200 million in U.S. victim-reported losses.”
The Treasury Department said Funnull’s operations are linked to the majority of virtual currency investment scam websites reported to the FBI. The agency said Funnull directly facilitated pig butchering and other schemes that resulted in more than $200 million in financial losses by Americans.
Pig butchering is a rampant form of fraud wherein people are lured by flirtatious strangers online into investing in fraudulent cryptocurrency trading platforms. Victims are coached to invest more and more money into what appears to be an extremely profitable trading platform, only to find their money is gone when they wish to cash out.
The scammers often insist that investors pay additional “taxes” on their crypto “earnings” before they can see their invested funds again (spoiler: they never do), and a shocking number of people have lost six figures or more through these pig butchering scams.
KrebsOnSecurity’s January story on Funnull was based on research from the security firm Silent Push, which discovered in October 2024 that a vast number of domains hosted via Funnull were promoting gambling sites that bore the logo of the Suncity Group, a Chinese entity named in a 2024 UN report (PDF) for laundering millions of dollars for the North Korean state-sponsored hacking group Lazarus.
Silent Push found Funnull was a criminal content delivery network (CDN) that carried a great deal of traffic tied to scam websites, funneling the traffic through a dizzying chain of auto-generated domain names and U.S.-based cloud providers before redirecting to malicious or phishous websites. The FBI has released a technical writeup (PDF) of the infrastructure used to manage the malicious Funnull domains between October 2023 and April 2025.
A graphic from the FBI explaining how Funnull generated a slew of new domains on a regular basis and mapped them to Internet addresses on U.S. cloud providers.
Silent Push revisited Funnull’s infrastructure in January 2025 and found Funnull was still using many of the same Amazon and Microsoft cloud Internet addresses identified as malicious in its October report. Both Amazon and Microsoft pledged to rid their networks of Funnull’s presence following that story, but according to Silent Push’s Zach Edwards only one of those companies has followed through.
Edwards said Silent Push no longer sees Microsoft Internet addresses showing up in Funnull’s infrastructure, while Amazon continues to struggle with removing Funnull servers, including one that appears to have first materialized in 2023.
“Amazon is doing a terrible job — every day since they made those claims to you and us in our public blog they have had IPs still mapped to Funnull, including some that have stayed mapped for inexplicable periods of time,” Edwards said.
Amazon said its Amazon Web Services (AWS) hosting platform actively counters abuse attempts.
“We have stopped hundreds of attempts this year related to this group and we are looking into the information you shared earlier today,” reads a statement shared by Amazon. “If anyone suspects that AWS resources are being used for abusive activity, they can report it to AWS Trust & Safety using the report abuse form here.”
U.S. based cloud providers remain an attractive home base for cybercriminal organizations because many organizations will not be overly aggressive in blocking traffic from U.S.-based cloud networks, as doing so can result in blocking access to many legitimate web destinations that are also on that same shared network segment or host.
What’s more, funneling their bad traffic so that it appears to be coming out of U.S. cloud Internet providers allows cybercriminals to connect to websites from web addresses that are geographically close(r) to their targets and victims (to sidestep location-based security controls by your bank, for example).
Funnull is not the only cybercriminal infrastructure-as-a-service provider that was sanctioned this month: On May 20, 2025, the European Union imposed sanctions on Stark Industries Solutions, an ISP that materialized at the start of Russia’s invasion of Ukraine and has been used as a global proxy network that conceals the true source of cyberattacks and disinformation campaigns against enemies of Russia.
In May 2024, KrebsOnSecurity published a deep dive on Stark Industries Solutions that found much of the malicious traffic traversing Stark’s network (e.g. vulnerability scanning and password brute force attacks) was being bounced through U.S.-based cloud providers. My reporting showed how deeply Stark had penetrated U.S. ISPs, and that its co-founder for many years sold “bulletproof” hosting services that told Russian cybercrime forum customers they would proudly ignore any abuse complaints or police inquiries.

That story examined the history of Stark’s co-founders, Moldovan brothers Ivan and Yuri Neculiti, who each denied past involvement in cybercrime or any current involvement in assisting Russian disinformation efforts or cyberattacks. Nevertheless, the EU sanctioned both brothers as well.
The EU said Stark and the Neculti brothers “enabled various Russian state-sponsored and state-affiliated actors to conduct destabilising activities including coordinated information manipulation and interference and cyber-attacks against the Union and third countries by providing services intended to hide these activities from European law enforcement and security agencies.”
Authorities in Pakistan have arrested 21 individuals accused of operating “Heartsender,” a once popular spam and malware dissemination service that operated for more than a decade. The main clientele for HeartSender were organized crime groups that tried to trick victim companies into making payments to a third party, and its alleged proprietors were publicly identified by KrebsOnSecurity in 2021 after they inadvertently infected their computers with malware.
Some of the core developers and sellers of Heartsender posing at a work outing in 2021. WeCodeSolutions boss Rameez Shahzad (in sunglasses) is in the center of this group photo, which was posted by employee Burhan Ul Haq, pictured just to the right of Shahzad.
A report from the Pakistani media outlet Dawn states that authorities there arrested 21 people alleged to have operated Heartsender, a spam delivery service whose homepage openly advertised phishing kits targeting users of various Internet companies, including Microsoft 365, Yahoo, AOL, Intuit, iCloud and ID.me. Pakistan’s National Cyber Crime Investigation Agency (NCCIA) reportedly conducted raids in Lahore’s Bahria Town and Multan on May 15 and 16.
The NCCIA told reporters the group’s tools were connected to more than $50m in losses in the United States alone, with European authorities investigating 63 additional cases.
“This wasn’t just a scam operation – it was essentially a cybercrime university that empowered fraudsters globally,” NCCIA Director Abdul Ghaffar said at a press briefing.
In January 2025, the FBI and the Dutch Police seized the technical infrastructure for the cybercrime service, which was marketed under the brands Heartsender, Fudpage and Fudtools (and many other “fud” variations). The “fud” bit stands for “Fully Un-Detectable,” and it refers to cybercrime resources that will evade detection by security tools like antivirus software or anti-spam appliances.
The FBI says transnational organized crime groups that purchased these services primarily used them to run business email compromise (BEC) schemes, wherein the cybercrime actors tricked victim companies into making payments to a third party.
Dawn reported that those arrested included Rameez Shahzad, the alleged ringleader of the Heartsender cybercrime business, which most recently operated under the Pakistani front company WeCodeSolutions. Mr. Shahzad was named and pictured in a 2021 KrebsOnSecurity story about a series of remarkable operational security mistakes that exposed their identities and Facebook pages showing employees posing for group photos and socializing at work-related outings.
Prior to folding their operations behind WeCodeSolutions, Shahzad and others arrested this month operated as a web hosting group calling itself The Manipulaters. KrebsOnSecurity first wrote about The Manipulaters in May 2015, mainly because their ads at the time were blanketing a number of popular cybercrime forums, and because they were fairly open and brazen about what they were doing — even who they were in real life.
Sometime in 2019, The Manipulaters failed to renew their core domain name — manipulaters[.]com — the same one tied to so many of the company’s business operations. That domain was quickly scooped up by Scylla Intel, a cyber intelligence firm that specializes in connecting cybercriminals to their real-life identities. Soon after, Scylla started receiving large amounts of email correspondence intended for the group’s owners.
In 2024, DomainTools.com found the web-hosted version of Heartsender leaked an extraordinary amount of user information to unauthenticated users, including customer credentials and email records from Heartsender employees. DomainTools says the malware infections on Manipulaters PCs exposed “vast swaths of account-related data along with an outline of the group’s membership, operations, and position in the broader underground economy.”
Shahzad allegedly used the alias “Saim Raza,” an identity which has contacted KrebsOnSecurity multiple times over the past decade with demands to remove stories published about the group. The Saim Raza identity most recently contacted this author in November 2024, asserting they had quit the cybercrime industry and turned over a new leaf after a brush with the Pakistani police.
The arrested suspects include Rameez Shahzad, Muhammad Aslam (Rameez’s father), Atif Hussain, Muhammad Umar Irshad, Yasir Ali, Syed Saim Ali Shah, Muhammad Nowsherwan, Burhanul Haq, Adnan Munawar, Abdul Moiz, Hussnain Haider, Bilal Ahmad, Dilbar Hussain, Muhammad Adeel Akram, Awais Rasool, Usama Farooq, Usama Mehmood and Hamad Nawaz.

The U.S. government today unsealed criminal charges against 16 individuals accused of operating and selling DanaBot, a prolific strain of information-stealing malware that has been sold on Russian cybercrime forums since 2018. The FBI says a newer version of DanaBot was used for espionage, and that many of the defendants exposed their real-life identities after accidentally infecting their own systems with the malware.

Initially spotted in May 2018 by researchers at the email security firm Proofpoint, DanaBot is a malware-as-a-service platform that specializes in credential theft and banking fraud.
Today, the U.S. Department of Justice unsealed a criminal complaint and indictment from 2022, which said the FBI identified at least 40 affiliates who were paying between $3,000 and $4,000 a month for access to the information stealer platform.
The government says the malware infected more than 300,000 systems globally, causing estimated losses of more than $50 million. The ringleaders of the DanaBot conspiracy are named as Aleksandr Stepanov, 39, a.k.a. “JimmBee,” and Artem Aleksandrovich Kalinkin, 34, a.k.a. “Onix”, both of Novosibirsk, Russia. Kalinkin is an IT engineer for the Russian state-owned energy giant Gazprom. His Facebook profile name is “Maffiozi.”
According to the FBI, there were at least two major versions of DanaBot; the first was sold between 2018 and June 2020, when the malware stopped being offered on Russian cybercrime forums. The government alleges that the second version of DanaBot — emerging in January 2021 — was provided to co-conspirators for use in targeting military, diplomatic and non-governmental organization computers in several countries, including the United States, Belarus, the United Kingdom, Germany, and Russia.
“Unindicted co-conspirators would use the Espionage Variant to compromise computers around the world and steal sensitive diplomatic communications, credentials, and other data from these targeted victims,” reads a grand jury indictment dated Sept. 20, 2022. “This stolen data included financial transactions by diplomatic staff, correspondence concerning day-to-day diplomatic activity, as well as summaries of a particular country’s interactions with the United States.”
The indictment says the FBI in 2022 seized servers used by the DanaBot authors to control their malware, as well as the servers that stored stolen victim data. The government said the server data also show numerous instances in which the DanaBot defendants infected their own PCs, resulting in their credential data being uploaded to stolen data repositories that were seized by the feds.
“In some cases, such self-infections appeared to be deliberately done in order to test, analyze, or improve the malware,” the criminal complaint reads. “In other cases, the infections seemed to be inadvertent – one of the hazards of committing cybercrime is that criminals will sometimes infect themselves with their own malware by mistake.”

A statement from the DOJ says that as part of today’s operation, agents with the Defense Criminal Investigative Service (DCIS) seized the DanaBot control servers, including dozens of virtual servers hosted in the United States. The government says it is now working with industry partners to notify DanaBot victims and help remediate infections. The statement credits a number of security firms with providing assistance to the government, including ESET, Flashpoint, Google, Intel 471, Lumen, PayPal, Proofpoint, Team CYMRU, and ZScaler.
It’s not unheard of for financially-oriented malicious software to be repurposed for espionage. A variant of the ZeuS Trojan, which was used in countless online banking attacks against companies in the United States and Europe between 2007 and at least 2015, was for a time diverted to espionage tasks by its author.
As detailed in this 2015 story, the author of the ZeuS trojan created a custom version of the malware to serve purely as a spying machine, which scoured infected systems in Ukraine for specific keywords in emails and documents that would likely only be found in classified documents.
The public charging of the 16 DanaBot defendants comes a day after Microsoft joined a slew of tech companies in disrupting the IT infrastructure for another malware-as-a-service offering — Lumma Stealer, which is likewise offered to affiliates under tiered subscription prices ranging from $250 to $1,000 per month. Separately, Microsoft filed a civil lawsuit to seize control over 2,300 domain names used by Lumma Stealer and its affiliates.

KrebsOnSecurity last week was hit by a near record distributed denial-of-service (DDoS) attack that clocked in at more than 6.3 terabits of data per second (a terabit is one trillion bits of data). The brief attack appears to have been a test run for a massive new Internet of Things (IoT) botnet capable of launching crippling digital assaults that few web destinations can withstand. Read on for more about the botnet, the attack, and the apparent creator of this global menace.
For reference, the 6.3 Tbps attack last week was ten times the size of the assault launched against this site in 2016 by the Mirai IoT botnet, which held KrebsOnSecurity offline for nearly four days. The 2016 assault was so large that Akamai – which was providing pro-bono DDoS protection for KrebsOnSecurity at the time — asked me to leave their service because the attack was causing problems for their paying customers.
Since the Mirai attack, KrebsOnSecurity.com has been behind the protection of Project Shield, a free DDoS defense service that Google provides to websites offering news, human rights, and election-related content. Google Security Engineer Damian Menscher told KrebsOnSecurity the May 12 attack was the largest Google has ever handled. In terms of sheer size, it is second only to a very similar attack that Cloudflare mitigated and wrote about in April.
After comparing notes with Cloudflare, Menscher said the botnet that launched both attacks bears the fingerprints of Aisuru, a digital siege machine that first surfaced less than a year ago. Menscher said the attack on KrebsOnSecurity lasted less than a minute, hurling large UDP data packets at random ports at a rate of approximately 585 million data packets per second.
“It was the type of attack normally designed to overwhelm network links,” Menscher said, referring to the throughput connections between and among various Internet service providers (ISPs). “For most companies, this size of attack would kill them.”

The Aisuru botnet comprises a globally-dispersed collection of hacked IoT devices, including routers, digital video recorders and other systems that are commandeered via default passwords or software vulnerabilities. As documented by researchers at QiAnXin XLab, the botnet was first identified in an August 2024 attack on a large gaming platform.
Aisuru reportedly went quiet after that exposure, only to reappear in November with even more firepower and software exploits. In a January 2025 report, XLab found the new and improved Aisuru (a.k.a. “Airashi“) had incorporated a previously unknown zero-day vulnerability in Cambium Networks cnPilot routers.
The people behind the Aisuru botnet have been peddling access to their DDoS machine in public Telegram chat channels that are closely monitored by multiple security firms. In August 2024, the botnet was rented out in subscription tiers ranging from $150 per day to $600 per week, offering attacks of up to two terabits per second.
“You may not attack any measurement walls, healthcare facilities, schools or government sites,” read a notice posted on Telegram by the Aisuru botnet owners in August 2024.
Interested parties were told to contact the Telegram handle “@yfork” to purchase a subscription. The account @yfork previously used the nickname “Forky,” an identity that has been posting to public DDoS-focused Telegram channels since 2021.
According to the FBI, Forky’s DDoS-for-hire domains have been seized in multiple law enforcement operations over the years. Last year, Forky said on Telegram he was selling the domain stresser[.]best, which saw its servers seized by the FBI in 2022 as part of an ongoing international law enforcement effort aimed at diminishing the supply of and demand for DDoS-for-hire services.
“The operator of this service, who calls himself ‘Forky,’ operates a Telegram channel to advertise features and communicate with current and prospective DDoS customers,” reads an FBI seizure warrant (PDF) issued for stresser[.]best. The FBI warrant stated that on the same day the seizures were announced, Forky posted a link to a story on this blog that detailed the domain seizure operation, adding the comment, “We are buying our new domains right now.”
A screenshot from the FBI’s seizure warrant for Forky’s DDoS-for-hire domains shows Forky announcing the resurrection of their service at new domains.
Approximately ten hours later, Forky posted again, including a screenshot of the stresser[.]best user dashboard, instructing customers to use their saved passwords for the old website on the new one.
A review of Forky’s posts to public Telegram channels — as indexed by the cyber intelligence firms Unit 221B and Flashpoint — reveals a 21-year-old individual who claims to reside in Brazil [full disclosure: Flashpoint is currently an advertiser on this blog].
Since late 2022, Forky’s posts have frequently promoted a DDoS mitigation company and ISP that he operates called botshield[.]io. The Botshield website is connected to a business entity registered in the United Kingdom called Botshield LTD, which lists a 21-year-old woman from Sao Paulo, Brazil as the director. Internet routing records indicate Botshield (AS213613) currently controls several hundred Internet addresses that were allocated to the company earlier this year.
Domaintools.com reports that botshield[.]io was registered in July 2022 to a Kaike Southier Leite in Sao Paulo. A LinkedIn profile by the same name says this individual is a network specialist from Brazil who works in “the planning and implementation of robust network infrastructures, with a focus on security, DDoS mitigation, colocation and cloud server services.”

In his posts to public Telegram chat channels, Forky has hardly attempted to conceal his whereabouts or identity. In countless chat conversations indexed by Unit 221B, Forky could be seen talking about everyday life in Brazil, often remarking on the extremely low or high prices in Brazil for a range of goods, from computer and networking gear to narcotics and food.
Reached via Telegram, Forky claimed he was “not involved in this type of illegal actions for years now,” and that the project had been taken over by other unspecified developers. Forky initially told KrebsOnSecurity he had been out of the botnet scene for years, only to concede this wasn’t true when presented with public posts on Telegram from late last year that clearly showed otherwise.
Forky denied being involved in the attack on KrebsOnSecurity, but acknowledged that he helped to develop and market the Aisuru botnet. Forky claims he is now merely a staff member for the Aisuru botnet team, and that he stopped running the botnet roughly two months ago after starting a family. Forky also said the woman named as director of Botshield is related to him.
Forky offered equivocal, evasive responses to a number of questions about the Aisuru botnet and his business endeavors. But on one point he was crystal clear:
“I have zero fear about you, the FBI, or Interpol,” Forky said, asserting that he is now almost entirely focused on their hosting business — Botshield.
Forky declined to discuss the makeup of his ISP’s clientele, or to clarify whether Botshield was more of a hosting provider or a DDoS mitigation firm. However, Forky has posted on Telegram about Botshield successfully mitigating large DDoS attacks launched against other DDoS-for-hire services.
DomainTools finds the same Sao Paulo street address in the registration records for botshield[.]io was used to register several other domains, including cant-mitigate[.]us. The email address in the WHOIS records for that domain is forkcontato@gmail.com, which DomainTools says was used to register the domain for the now-defunct DDoS-for-hire service stresser[.]us, one of the domains seized in the FBI’s 2023 crackdown.
On May 8, 2023, the U.S. Department of Justice announced the seizure of stresser[.]us, along with a dozen other domains offering DDoS services. The DOJ said ten of the 13 domains were reincarnations of services that were seized during a prior sweep in December, which targeted 48 top stresser services (also known as “booters”).
Forky claimed he could find out who attacked my site with Aisuru. But when pressed a day later on the question, Forky said he’d come up empty-handed.
“I tried to ask around, all the big guys are not retarded enough to attack you,” Forky explained in an interview on Telegram. “I didn’t have anything to do with it. But you are welcome to write the story and try to put the blame on me.”
The 6.3 Tbps attack last week caused no visible disruption to this site, in part because it was so brief — lasting approximately 45 seconds. DDoS attacks of such magnitude and brevity typically are produced when botnet operators wish to test or demonstrate their firepower for the benefit of potential buyers. Indeed, Google’s Menscher said it is likely that both the May 12 attack and the slightly larger 6.5 Tbps attack against Cloudflare last month were simply tests of the same botnet’s capabilities.
In many ways, the threat posed by the Aisuru/Airashi botnet is reminiscent of Mirai, an innovative IoT malware strain that emerged in the summer of 2016 and successfully out-competed virtually all other IoT malware strains in existence at the time.
As first revealed by KrebsOnSecurity in January 2017, the Mirai authors were two U.S. men who co-ran a DDoS mitigation service — even as they were selling far more lucrative DDoS-for-hire services using the most powerful botnet on the planet.
Less than a week after the Mirai botnet was used in a days-long DDoS against KrebsOnSecurity, the Mirai authors published the source code to their botnet so that they would not be the only ones in possession of it in the event of their arrest by federal investigators.
Ironically, the leaking of the Mirai source is precisely what led to the eventual unmasking and arrest of the Mirai authors, who went on to serve probation sentences that required them to consult with FBI investigators on DDoS investigations. But that leak also rapidly led to the creation of dozens of Mirai botnet clones, many of which were harnessed to fuel their own powerful DDoS-for-hire services.
Menscher told KrebsOnSecurity that as counterintuitive as it may sound, the Internet as a whole would probably be better off if the source code for Aisuru became public knowledge. After all, he said, the people behind Aisuru are in constant competition with other IoT botnet operators who are all striving to commandeer a finite number of vulnerable IoT devices globally.
Such a development would almost certainly cause a proliferation of Aisuru botnet clones, he said, but at least then the overall firepower from each individual botnet would be greatly diminished — or at least within range of the mitigation capabilities of most DDoS protection providers.
Barring a source code leak, Menscher said, it would be nice if someone published the full list of software exploits being used by the Aisuru operators to grow their botnet so quickly.
“Part of the reason Mirai was so dangerous was that it effectively took out competing botnets,” he said. “This attack somehow managed to compromise all these boxes that nobody else knows about. Ideally, we’d want to see that fragmented out, so that no [individual botnet operator] controls too much.”
In what experts are calling a novel legal outcome, the 22-year-old former administrator of the cybercrime community Breachforums will forfeit nearly $700,000 to settle a civil lawsuit from a health insurance company whose customer data was posted for sale on the forum in 2023. Conor Brian Fitzpatrick, a.k.a. “Pompompurin,” is slated for resentencing next month after pleading guilty to access device fraud and possession of child sexual abuse material (CSAM).

On January 18, 2023, denizens of Breachforums posted for sale tens of thousands of records — including Social Security numbers, dates of birth, addresses, and phone numbers — stolen from Nonstop Health, an insurance provider based in Concord, Calif.
Class-action attorneys sued Nonstop Health, which added Fitzpatrick as a third-party defendant to the civil litigation in November 2023, several months after he was arrested by the FBI and criminally charged with access device fraud and CSAM possession. In January 2025, Nonstop agreed to pay $1.5 million to settle the class action.
Jill Fertel is a former prosecutor who runs the cyber litigation practice at Cipriani & Werner, the law firm that represented Nonstop Health. Fertel told KrebsOnSecurity this is the first and only case where a cybercriminal or anyone related to the security incident was actually named in civil litigation.
“Civil plaintiffs are not at all likely to see money seized from threat actors involved in the incident to be made available to people impacted by the breach,” Fertel said. “The best we could do was make this money available to the class, but it’s still incumbent on the members of the class who are impacted to make that claim.”
Mark Rasch is a former federal prosecutor who now represents Unit 221B, a cybersecurity firm based in New York City. Rasch said he doesn’t doubt that the civil settlement involving Fitzpatrick’s criminal activity is a novel legal development.
“It is rare in these civil cases that you know the threat actor involved in the breach, and it’s also rare that you catch them with sufficient resources to be able to pay a claim,” Rasch said.
Despite admitting to possessing more than 600 CSAM images and personally operating Breachforums, Fitzpatrick was sentenced in January 2024 to time served and 20 years of supervised release. Federal prosecutors objected, arguing that his punishment failed to adequately reflect the seriousness of his crimes or serve as a deterrent.
An excerpt from a pre-sentencing report for Fitzpatrick indicates he had more than 600 CSAM images on his devices.
Indeed, the same month he was sentenced Fitzpatrick was rearrested (PDF) for violating the terms of his release, which forbade him from using a computer that didn’t have court-required monitoring software installed.
Federal prosecutors said Fitzpatrick went on Discord following his guilty plea and professed innocence to the very crimes to which he’d pleaded guilty, stating that his plea deal was “so BS” and that he had “wanted to fight it.” The feds said Fitzpatrick also joked with his friends about selling data to foreign governments, exhorting one user to “become a foreign asset to china or russia,” and to “sell government secrets.”
In January 2025, a federal appeals court agreed with the government’s assessment, vacating Fitzpatrick’s sentence and ordering him to be resentenced on June 3, 2025.
Fitzpatrick launched BreachForums in March 2022 to replace RaidForums, a similarly popular crime forum that was infiltrated and shut down by the FBI the previous month. As administrator, his alter ego Pompompurin served as the middleman, personally reviewing all databases for sale on the forum and offering an escrow service to those interested in buying stolen data.
A yearbook photo of Fitzpatrick unearthed by the Yonkers Times.
The new site quickly attracted more than 300,000 users, and facilitated the sale of databases stolen from hundreds of hacking victims, including some of the largest consumer data breaches in recent history. In May 2024, a reincarnation of Breachforums was seized by the FBI and international partners. Still more relaunches of the forum occurred after that, with the most recent disruption last month.
As KrebsOnSecurity reported last year in The Dark Nexus Between Harm Groups and The Com, it is increasingly common for federal investigators to find CSAM material when searching devices seized from cybercriminal suspects. While the mere possession of CSAM is a serious federal crime, not all of those caught with CSAM are necessarily creators or distributors of it. Fertel said some cybercriminal communities have been known to require new entrants to share CSAM material as a way of proving that they are not a federal investigator.
“If you’re going to the darkest corners of Internet, that’s how you prove you’re not law enforcement,” Fertel said. “Law enforcement would never share that material. It would be criminal for me as a prosecutor, if I obtained and possessed those types of images.”

Was that spinning head a mistake—or the whole point?
When McAfee dropped a new digital ad showing a woman lounging on a beach, only to have her head rotate a full 360 degrees, the internet lit up. Some viewers thought it was a post-production error. Others assumed it was a weird deepfake gone wrong. And while a few sharp-eyed commentators caught the joke right away, most were left wondering: was this brilliant marketing or a complete fail?
Spoiler: it was on purpose.
You may have seen the ad—the calm beach scene, the casual vibe, and then, the fully rotating head. Reactions ranged from confused to amused, with a handful of keen observers nodding in understanding.
We didn’t mess up.
With the help of our creative agency VSA, we developed a series of digital ads using generative AI to blur the line between real and surreal. The goal? To make a bigger point: AI is now capable of mimicking reality in subtle, clever ways that are increasingly hard to detect. That’s exactly why tools like McAfee’s Scam Detector matter more than ever.
“While the ads are clearly AI, the implication is that AI isn’t always so easy to spot,” said Anne-Marie Rosser, CEO of VSA. “It’s funny, and it creates empathy for the user since we’re all susceptible.”
And don’t worry—we didn’t hand everything over to the machines. McAfee and VSA’s full creative and design teams were instrumental in shaping every detail, from concept to execution. The AI was a tool. The vision came from real people.
These creative choices reflect our philosophy at McAfee: take cybersecurity seriously, but don’t always take yourself too seriously. Humor has the power to break through fear and shame—and ultimately, help people protect themselves better.
Alongside these eye-catching ads, we’re launching Scam Stories, a social campaign built around real voices. From concert ticket scams to spoofed customer service texts, people across the country are sharing their experiences using #KeepItReal and #MyScamStory—and we’re listening.
Some of those individuals, like actor Chris Carmack (of Grey’s Anatomy and The O.C.), have joined our campaign to share their own moments of being duped. Others, like cyber student Henry or life coach Cory, are helping us educate others by turning personal pain into public empowerment.
This campaign isn’t just about awareness—it’s about action. That’s why we’ve partnered with FightCybercrime.org, a nonprofit that helps people recognize, report, and recover from scams. We’re donating $50,000 worth of McAfee protection to people in FightCybercrime programs and to the volunteers who support them.
We’re also teaming up to expand education efforts through our Online Safety for Kids initiative—because building a safer internet starts early.
Scammers rely on silence, shame, and speed. But when we slow down, speak up, and share our stories, we take away their power.
The Keep It Real campaign is more than just a product launch. It’s a movement to stop the stigma around scams, help people protect their peace of mind, and remind you: if it can happen to Chris Carmack, it can happen to anyone.
So what’s your scam story? We’re listening.

When Grey’s Anatomy actor Chris Carmack and musician Erin Slaver tried to order custom patio cushions from what seemed like a trustworthy small business, they thought they were making a simple home upgrade.
But after clicking and paying through a special link, the cushions never arrived. Delays turned into excuses, messages went unanswered, and the seller’s account eventually disappeared—along with their money.
It was a scam. And like so many others, they were left frustrated, embarrassed, and unsure of what to do next.
Now, Chris and Erin are sharing their story—not just to warn others, but to help launch Scam Stories, a McAfee-led movement to end the stigma around being scammed, remind people that it can happen to anyone, and help keep everyone safer online.
Scammers win when we stay silent. At McAfee, we believe speaking out about your experience is a brave way to support your community and help others stay safe from scams.
Built-in partnership with FightCybercrime.org, the Scam Stories movement invites people to share their scam experiences, end the stigma around being scammed, and build a more informed, supportive community.
And Chris and Erin aren’t the only ones speaking up. Our campaign features stories from everyday people who’ve been scammed—and are now helping others by sharing what happened.
These scams happened fast—and could happen to anyone. Each one involved tactics that McAfee Scam Detector is designed to catch:
These stories are powerful reminders that scam prevention starts with awareness. And when people share what happened, it helps others recognize red flags and feel less alone.
FightCybercrime.org is a nonprofit dedicated to helping people recognize, report, and recover from cybercrime. Their tools, educational materials, and survivor support network make them an ideal partner in our mission.
Together with FightCybercrime.org, we’ll be expanding online safety education —and helping more people recover from scams with real support.
As part of our collaboration, McAfee is donating $50,000 worth of protection products to individuals going through FightCybercrime.org’s recovery programs and to the staff and volunteers who support them every day.
At McAfee, we believe that scam protection isn’t just about tools—it’s about empowering people with knowledge and support. And that starts by ending the stigma.
Scam Stories is here to change the narrative—from shame to strength. With help from public figures like Chris and Erin, and brave individuals across the country, we’re turning painful moments into teachable ones—and helping everyone stay safer online.
McAfee is collecting scam stories and encouraging people to share their experiences on social media using #MyScamStory and #KeepItReal.

In today’s online world, scams are everywhere—and they’re harder to spot than ever. From sophisticated phishing texts and deepfake videos to emails that look just like messages from your bank or delivery provider, scammers are constantly evolving. And so are we.
Introducing McAfee’s Scam Detector: advanced scam detection technology built to spot and stop scams across text messages, emails, and videos. It’s included at no extra cost in all core McAfee plans for customers in the U.S., UK, and Australia—helping millions stay safer online without having to upgrade.
Scam messages are getting smarter and more frequent. McAfee Labs saw scam text volumes nearly quadruple between February and March 2025. Nearly half used cloaked links to disguise malicious intent. Scams mimicked toll charges, deliveries, payment services, and even messages from loved ones.
Scammers use urgency and fear to push people into quick decisions—and it’s working. That’s why Scam Detector was designed with AI-powered detection, educational guidance, and coverage that works across multiple platforms and devices.
McAfee’s Scam Detector flags ~1.5% of text messages analyzed as potential scams and ~1.8% of email messages analyzed as potential scams. The text scam detection model included in the initial release achieves greater than 99% accuracy.
1) Smarter text scam detection
2) AI-based scam analysis for email
3) Deepfake detection for video
4) On-demand Scam Check
5) Custom Sensitivity Settings
Choose the level of detection that works for you:
6) Safe Browsing Layer
Scam Detector uses on-device AI wherever possible. That means your messages and data aren’t sent to the cloud for analysis. And because scam protection is now included in all core McAfee plans, there’s no need for additional purchases.
Scam Detector is now included in all core plans:
Available for customers in the U.S., UK, and Australia, this new feature rolls out automatically in the McAfee app. No upgrade required.
McAfee’s Scam Detector is designed to help people stay safer by identifying scams, explaining why they were flagged, and giving users more confidence in their digital decisions.
In a time when scams are harder to detect than ever, it’s one more way McAfee is protecting people—not just devices.

A Texas firm recently charged with conspiring to distribute synthetic opioids in the United States is at the center of a vast network of companies in the U.S. and Pakistan whose employees are accused of using online ads to scam westerners seeking help with trademarks, book writing, mobile app development and logo designs, a new investigation reveals.
In an indictment (PDF) unsealed last month, the U.S. Department of Justice said Dallas-based eWorldTrade “operated an online business-to-business marketplace that facilitated the distribution of synthetic opioids such as isotonitazene and carfentanyl, both significantly more potent than fentanyl.”
Launched in 2017, eWorldTrade[.]com now features a seizure notice from the DOJ. eWorldTrade operated as a wholesale seller of consumer goods, including clothes, machinery, chemicals, automobiles and appliances. The DOJ’s indictment includes no additional details about eWorldTrade’s business, origins or other activity, and at first glance the website might appear to be a legitimate e-commerce platform that also just happened to sell some restricted chemicals.
A screenshot of the eWorldTrade homepage on March 25, 2025. Image: archive.org.
However, an investigation into the company’s founders reveals they are connected to a sprawling network of websites that have a history of extortionate scams involving trademark registration, book publishing, exam preparation, and the design of logos, mobile applications and websites.
Records from the U.S. Patent and Trademark Office (USPTO) show the eWorldTrade mark is owned by an Azneem Bilwani in Karachi (this name also is in the registration records for the now-seized eWorldTrade domain). Mr. Bilwani is perhaps better known as the director of the Pakistan-based IT provider Abtach Ltd., which has been singled out by the USPTO and Google for operating trademark registration scams (the main offices for eWorldtrade and Abtach share the same address in Pakistan).
In November 2021, the USPTO accused Abtach of perpetrating “an egregious scheme to deceive and defraud applicants for federal trademark registrations by improperly altering official USPTO correspondence, overcharging application filing fees, misappropriating the USPTO’s trademarks, and impersonating the USPTO.”
Abtach offered trademark registration at suspiciously low prices compared to legitimate costs of over USD $1,500, and claimed they could register a trademark in 24 hours. Abtach reportedly rebranded to Intersys Limited after the USPTO banned Abtach from filing any more trademark applications.
In a note published to its LinkedIn profile, Intersys Ltd. asserted last year that certain scam firms in Karachi were impersonating the company.
Many of Abtach’s employees are former associates of a similar company in Pakistan called Axact that was targeted by Pakistani authorities in a 2015 fraud investigation. Axact came under law enforcement scrutiny after The New York Times ran a front-page story about the company’s most lucrative scam business: Hundreds of sites peddling fake college degrees and diplomas.
People who purchased fake certifications were subsequently blackmailed by Axact employees posing as government officials, who would demand additional payments under threats of prosecution or imprisonment for having bought fraudulent “unauthorized” academic degrees. This practice created a continuous cycle of extortion, internally referred to as “upselling.”
“Axact took money from at least 215,000 people in 197 countries — one-third of them from the United States,” The Times reported. “Sales agents wielded threats and false promises and impersonated government officials, earning the company at least $89 million in its final year of operation.”
Dozens of top Axact employees were arrested, jailed, held for months, tried and sentenced to seven years for various fraud violations. But a 2019 research brief on Axact’s diploma mills found none of those convicted had started their prison sentence, and that several had fled Pakistan and never returned.
“In October 2016, a Pakistan district judge acquitted 24 Axact officials at trial due to ‘not enough evidence’ and then later admitted he had accepted a bribe (of $35,209) from Axact,” reads a history (PDF) published by the American Association of Collegiate Registrars and Admissions Officers.
In 2021, Pakistan’s Federal Investigation Agency (FIA) charged Bilwani and nearly four dozen others — many of them Abtach employees — with running an elaborate trademark scam. The authorities called it “the biggest money laundering case in the history of Pakistan,” and named a number of businesses based in Texas that allegedly helped move the proceeds of cybercrime.
A page from the March 2021 FIA report alleging that Digitonics Labs and Abtach employees conspired to extort and defraud consumers.
The FIA said the defendants operated a large number of websites offering low-cost trademark services to customers, before then “ignoring them after getting the funds and later demanding more funds from clients/victims in the name of up-sale (extortion).” The Pakistani law enforcement agency said that about 75 percent of customers received fake or fabricated trademarks as a result of the scams.
The FIA found Abtach operates in conjunction with a Karachi firm called Digitonics Labs, which earned a monthly revenue of around $2.5 million through the “extortion of international clients in the name of up-selling, the sale of fake/fabricated USPTO certificates, and the maintaining of phishing websites.”
According the Pakistani authorities, the accused also ran countless scams involving ebook publication and logo creation, wherein customers are subjected to advance-fee fraud and extortion — with the scammers demanding more money for supposed “copyright release” and threatening to release the trademark.
Also charged by the FIA was Junaid Mansoor, the owner of Digitonics Labs in Karachi. Mansoor’s U.K.-registered company Maple Solutions Direct Limited has run at least 700 ads for logo design websites since 2015, the Google Ads Transparency page reports. The company has approximately 88 ads running on Google as of today.

Mr. Mansoor is actively involved with and promoting a Quran study business called quranmasteronline[.]com, which was founded by Junaid’s brother Qasim Mansoor (Qasim is also named in the FIA criminal investigation). The Google ads promoting quranmasteronline[.]com were paid for by the same account advertising a number of scam websites selling logo and web design services.
Junaid Mansoor did not respond to requests for comment. An address in Teaneck, New Jersey where Mr. Mansoor previously lived is listed as an official address of exporthub[.]com, a Pakistan-based e-commerce website that appears remarkably similar to eWorldTrade (Exporthub says its offices are in Texas). Interestingly, a search in Google for this domain shows ExportHub currently features multiple listings for fentanyl citrate from suppliers in China and elsewhere.
The CEO of Digitonics Labs is Muhammad Burhan Mirza, a former Axact official who was arrested by the FIA as part of its money laundering and trademark fraud investigation in 2021. In 2023, prosecutors in Pakistan charged Mirza, Mansoor and 14 other Digitonics employees with fraud, impersonating government officials, phishing, cheating and extortion. Mirza’s LinkedIn profile says he currently runs an educational technology/life coach enterprise called TheCoach360, which purports to help young kids “achieve financial independence.”
Reached via LinkedIn, Mr. Mirza denied having anything to do with eWorldTrade or any of its sister companies in Texas.
“Moreover, I have no knowledge as to the companies you have mentioned,” said Mr. Mirza, who did not respond to follow-up questions.
The current disposition of the FIA’s fraud case against the defendants is unclear. The investigation was marred early on by allegations of corruption and bribery. In 2021, Pakistani authorities alleged Bilwani paid a six-figure bribe to FIA investigators. Meanwhile, attorneys for Mr. Bilwani have argued that although their client did pay a bribe, the payment was solicited by government officials. Mr. Bilwani did not respond to requests for comment.
KrebsOnSecurity has learned that the people and entities at the center of the FIA investigations have built a significant presence in the United States, with a strong concentration in Texas. The Texas businesses promote websites that sell logo and web design, ghostwriting, and academic cheating services. Many of these entities have recently been sued for fraud and breach of contract by angry former customers, who claimed the companies relentlessly upsold them while failing to produce the work as promised.
For example, the FIA complaints named Retrocube LLC and 360 Digital Marketing LLC, two entities that share a street address with eWorldTrade: 1910 Pacific Avenue, Suite 8025, Dallas, Texas. Also incorporated at that Pacific Avenue address is abtach[.]ae, a web design and marketing firm based in Dubai; and intersyslimited[.]com, the new name of Abtach after they were banned by the USPTO. Other businesses registered at this address market services for logo design, mobile app development, and ghostwriting.
A list published in 2021 by Pakistan’s FIA of different front companies allegedly involved in scamming people who are looking for help with trademarks, ghostwriting, logos and web design.
360 Digital Marketing’s website 360digimarketing[.]com is owned by an Abtach front company called Abtech LTD. Meanwhile, business records show 360 Digi Marketing LTD is a U.K. company whose officers include former Abtach director Bilwani; Muhammad Saad Iqbal, formerly Abtach, now CEO of Intersys Ltd; Niaz Ahmed, a former Abtach associate; and Muhammad Salman Yousuf, formerly a vice president at Axact, Abtach, and Digitonics Labs.
Google’s Ads Transparency Center finds 360 Digital Marketing LLC ran at least 500 ads promoting various websites selling ghostwriting services . Another entity tied to Junaid Mansoor — a company called Octa Group Technologies AU — has run approximately 300 Google ads for book publishing services, promoting confusingly named websites like amazonlistinghub[.]com and barnesnoblepublishing[.]co.
360 Digital Marketing LLC ran approximately 500 ads for scam ghostwriting sites.
Rameez Moiz is a Texas resident and former Abtach product manager who has represented 360 Digital Marketing LLC and RetroCube. Moiz told KrebsOnSecurity he stopped working for 360 Digital Marketing in the summer of 2023. Mr. Moiz did not respond to follow-up questions, but an Upwork profile for him states that as of April 2025 he is employed by Dallas-based Vertical Minds LLC.
In April 2025, California resident Melinda Will sued the Texas firm Majestic Ghostwriting — which is doing business as ghostwritingsquad[.]com — alleging they scammed her out of $100,000 after she hired them to help write her book. Google’s ad transparency page shows Moiz’s employer Vertical Minds LLC paid to run approximately 55 ads for ghostwritingsquad[.]com and related sites.
Google’s ad transparency listing for ghostwriting ads paid for by Vertical Minds LLC.
Ms. Will’s lawsuit is just one of more than two dozen complaints over the past four years wherein plaintiffs sued one of this group’s web design, wiki editing or ghostwriting services. In 2021, a New Jersey man sued Octagroup Technologies, alleging they ripped him off when he paid a total of more than $26,000 for the design and marketing of a web-based mapping service.
The plaintiff in that case did not respond to requests for comment, but his complaint alleges Octagroup and a myriad other companies it contracted with produced minimal work product despite subjecting him to relentless upselling. That case was decided in favor of the plaintiff because the defendants never contested the matter in court.
In 2023, 360 Digital Marketing LLC and Retrocube LLC were sued by a woman who said they scammed her out of $40,000 over a book she wanted help writing. That lawsuit helpfully showed an image of the office front door at 1910 Pacific Ave Suite 8025, which featured the logos of 360 Digital Marketing, Retrocube, and eWorldTrade.

The lawsuit was filed pro se by Leigh Riley, a 64-year-old career IT professional who paid 360 Digital Marketing to have a company called Talented Ghostwriter co-author and promote a series of books she’d outlined on spirituality and healing.
“The main reason I hired them was because I didn’t understand what I call the formula for writing a book, and I know there’s a lot of marketing that goes into publishing,” Riley explained in an interview. “I know nothing about that stuff, and these guys were convincing that they could handle all aspects of it. Until I discovered they couldn’t write a damn sentence in English properly.”
Riley’s well-documented lawsuit (not linked here because it features a great deal of personal information) includes screenshots of conversations with the ghostwriting team, which was constantly assigning her to new writers and editors, and ghosting her on scheduled conference calls about progress on the project. Riley said she ended up writing most of the book herself because the work they produced was unusable.
“Finally after months of promising the books were printed and on their way, they show up at my doorstep with the wrong title on the book,” Riley said. When she demanded her money back, she said the people helping her with the website to promote the book locked her out of the site.
A conversation snippet from Leigh Riley’s lawsuit against Talented Ghostwriter, aka 360 Digital Marketing LLC. “Other companies once they have you money they don’t even respond or do anything,” the ghostwriting team manager explained.
Riley decided to sue, naming 360 Digital Marketing LLC and Retrocube LLC, among others. The companies offered to settle the matter for $20,000, which she accepted. “I didn’t have money to hire a lawyer, and I figured it was time to cut my losses,” she said.
Riley said she could have saved herself a great deal of headache by doing some basic research on Talented Ghostwriter, whose website claims the company is based in Los Angeles. According to the California Secretary of State, however, there is no registered entity by that name. Rather, the address claimed by talentedghostwriter[.]com is a vacant office building with a “space available” sign in the window.
California resident Walter Horsting discovered something similar when he sued 360 Digital Marketing in small claims court last year, after hiring a company called Vox Ghostwriting to help write, edit and promote a spy novel he’d been working on. Horsting said he paid Vox $3,300 to ghostwrite a 280-page book, and was upsold an Amazon marketing and publishing package for $7,500.
In an interview, Horsting said the prose that Vox Ghostwriting produced was “juvenile at best,” forcing him to rewrite and edit the work himself, and to partner with a graphical artist to produce illustrations. Horsting said that when it came time to begin marketing the novel, Vox Ghostwriting tried to further upsell him on marketing packages, while dodging scheduled meetings with no follow-up.
“They have a money back guarantee, and when they wouldn’t refund my money I said I’m taking you to court,” Horsting recounted. “I tried to serve them in Los Angeles but found no such office exists. I talked to a salon next door and they said someone else had recently shown up desperately looking for where the ghostwriting company went, and it appears there are a trail of corpses on this. I finally tracked down where they are in Texas.”
It was the same office that Ms. Riley served her lawsuit against. Horsting said he has a court hearing scheduled later this month, but he’s under no illusions that winning the case means he’ll be able to collect.
“At this point, I’m doing it out of pride more than actually expecting anything to come to good fortune for me,” he said.
The following mind map was helpful in piecing together key events, individuals and connections mentioned above. It’s important to note that this graphic only scratches the surface of the operations tied to this group. For example, in Case 2 we can see mention of academic cheating services, wherein people can be hired to take online proctored exams on one’s behalf. Those who hire these services soon find themselves subject to impersonation and blackmail attempts for larger and larger sums of money, with the threat of publicly exposing their unethical academic cheating activity.

KrebsOnSecurity reviewed the Google Ad Transparency links for nearly 500 different websites tied to this network of ghostwriting, logo, app and web development businesses. Those website names were then fed into spyfu.com, a competitive intelligence company that tracks the reach and performance of advertising keywords. Spyfu estimates that between April 2023 and April 2025, those websites spent more than $10 million on Google ads.
Reached for comment, Google said in a written statement that it is constantly policing its ad network for bad actors, pointing to an ads safety report (PDF) showing Google blocked or removed 5.1 billion bad ads last year — including more than 500 million ads related to trademarks.
“Our policy against Enabling Dishonest Behavior prohibits products or services that help users mislead others, including ads for paper-writing or exam-taking services,” the statement reads. “When we identify ads or advertisers that violate our policies, we take action, including by suspending advertiser accounts, disapproving ads, and restricting ads to specific domains when appropriate.”
Google did not respond to specific questions about the advertising entities mentioned in this story, saying only that “we are actively investigating this matter and addressing any policy violations, including suspending advertiser accounts when appropriate.”
From reviewing the ad accounts that have been promoting these scam websites, it appears Google has very recently acted to remove a large number of the offending ads. Prior to my notifying Google about the extent of this ad network on April 28, the Google Ad Transparency network listed over 500 ads for 360 Digital Marketing; as of this publication, that number had dwindled to 10.
On April 30, Google announced that starting this month its ads transparency page will display the payment profile name as the payer name for verified advertisers, if that name differs from their verified advertiser name. Searchengineland.com writes the changes are aimed at increasing accountability in digital advertising.
This spreadsheet lists the domain names, advertiser names, and Google Ad Transparency links for more than 350 entities offering ghostwriting, publishing, web design and academic cheating services.
KrebsOnSecurity would like to thank the anonymous security researcher NatInfoSec for their assistance in this investigation.

A 23-year-old Scottish man thought to be a member of the prolific Scattered Spider cybercrime group was extradited last week from Spain to the United States, where he is facing charges of wire fraud, conspiracy and identity theft. U.S. prosecutors allege Tyler Robert Buchanan and co-conspirators hacked into dozens of companies in the United States and abroad, and that he personally controlled more than $26 million stolen from victims.
Scattered Spider is a loosely affiliated criminal hacking group whose members have broken into and stolen data from some of the world’s largest technology companies. Buchanan was arrested in Spain last year on a warrant from the FBI, which wanted him in connection with a series of SMS-based phishing attacks in the summer of 2022 that led to intrusions at Twilio, LastPass, DoorDash, Mailchimp, and many other tech firms.
Tyler Buchanan, being escorted by Spanish police at the airport in Palma de Mallorca in June 2024.
As first reported by KrebsOnSecurity, Buchanan (a.k.a. “tylerb”) fled the United Kingdom in February 2023, after a rival cybercrime gang hired thugs to invade his home, assault his mother, and threaten to burn him with a blowtorch unless he gave up the keys to his cryptocurrency wallet. Buchanan was arrested in June 2024 at the airport in Palma de Mallorca while trying to board a flight to Italy. His extradition to the United States was first reported last week by Bloomberg.
Members of Scattered Spider have been tied to the 2023 ransomware attacks against MGM and Caesars casinos in Las Vegas, but it remains unclear whether Buchanan was implicated in that incident. The Justice Department’s complaint against Buchanan makes no mention of the 2023 ransomware attack.
Rather, the investigation into Buchanan appears to center on the SMS phishing campaigns from 2022, and on SIM-swapping attacks that siphoned funds from individual cryptocurrency investors. In a SIM-swapping attack, crooks transfer the target’s phone number to a device they control and intercept any text messages or phone calls to the victim’s device — including one-time passcodes for authentication and password reset links sent via SMS.
In August 2022, KrebsOnSecurity reviewed data harvested in a months-long cybercrime campaign by Scattered Spider involving countless SMS-based phishing attacks against employees at major corporations. The security firm Group-IB called them by a different name — 0ktapus, because the group typically spoofed the identity provider Okta in their phishing messages to employees at targeted firms.

The complaint against Buchanan (PDF) says the FBI tied him to the 2022 SMS phishing attacks after discovering the same username and email address was used to register numerous Okta-themed phishing domains seen in the campaign. The domain registrar NameCheap found that less than a month before the phishing spree, the account that registered those domains logged in from an Internet address in the U.K. FBI investigators said the Scottish police told them the address was leased to Buchanan from January 26, 2022 to November 7, 2022.
Authorities seized at least 20 digital devices when they raided Buchanan’s residence, and on one of those devices they found usernames and passwords for employees of three different companies targeted in the phishing campaign.
“The FBI’s investigation to date has gathered evidence showing that Buchanan and his co-conspirators targeted at least 45 companies in the United States and abroad, including Canada, India, and the United Kingdom,” the FBI complaint reads. “One of Buchanan’s devices contained a screenshot of Telegram messages between an account known to be used by Buchanan and other unidentified co-conspirators discussing dividing up the proceeds of SIM swapping.”
U.S. prosecutors allege that records obtained from Discord showed the same U.K. Internet address was used to operate a Discord account that specified a cryptocurrency wallet when asking another user to send funds. The complaint says the publicly available transaction history for that payment address shows approximately 391 bitcoin was transferred in and out of this address between October 2022 and
February 2023; 391 bitcoin is presently worth more than $26 million.
In November 2024, federal prosecutors in Los Angeles unsealed criminal charges against Buchanan and four other alleged Scattered Spider members, including Ahmed Elbadawy, 23, of College Station, Texas; Joel Evans, 25, of Jacksonville, North Carolina; Evans Osiebo, 20, of Dallas; and Noah Urban, 20, of Palm Coast, Florida. KrebsOnSecurity reported last year that another suspected Scattered Spider member — a 17-year-old from the United Kingdom — was arrested as part of a joint investigation with the FBI into the MGM hack.
Mr. Buchanan’s court-appointed attorney did not respond to a request for comment. The accused faces charges of wire fraud conspiracy, conspiracy to obtain information by computer for private financial gain, and aggravated identity theft. Convictions on the latter charge carry a minimum sentence of two years in prison.
Documents from the U.S. District Court for the Central District of California indicate Buchanan is being held without bail pending trial. A preliminary hearing in the case is slated for May 6.
