KrebsOnSecurity recently heard from a reader whose boss’s email account got phished and was used to trick one of the company’s customers into sending a large payment to scammers. An investigation into the attacker’s infrastructure points to a long-running Nigerian cybercrime ring that is actively targeting established companies in the transportation and aviation industries.

A reader who works in the transportation industry sent a tip about a recent successful phishing campaign that tricked an executive at the company into entering their credentials at a fake Microsoft 365 login page. From there, the attackers quickly mined the executive’s inbox for past communications about invoices, copying and modifying some of those messages with new invoice demands that were sent to some of the company’s customers and partners.
Speaking on condition of anonymity, the reader said the resulting phishing emails to customers came from a newly registered domain name that was remarkably similar to their employer’s domain, and that at least one of their customers fell for the ruse and paid a phony invoice. They said the attackers had spun up a look-alike domain just a few hours after the executive’s inbox credentials were phished, and that the scam resulted in a customer suffering a six-figure financial loss.
The reader also shared that the email addresses in the registration records for the imposter domain — roomservice801@gmail.com — is tied to many such phishing domains. Indeed, a search on this email address at DomainTools.com finds it is associated with at least 240 domains registered in 2024 or 2025. Virtually all of them mimic legitimate domains for companies in the aerospace and transportation industries worldwide.
An Internet search for this email address reveals a humorous blog post from 2020 on the Russian forum hackware[.]ru, which found roomservice801@gmail.com was tied to a phishing attack that used the lure of phony invoices to trick the recipient into logging in at a fake Microsoft login page. We’ll come back to this research in a moment.
DomainTools shows that some of the early domains registered to roomservice801@gmail.com in 2016 include other useful information. For example, the WHOIS records for alhhomaidhicentre[.]biz reference the technical contact of “Justy John” and the email address justyjohn50@yahoo.com.
A search at DomainTools found justyjohn50@yahoo.com has been registering one-off phishing domains since at least 2012. At this point, I was convinced that some security company surely had already published an analysis of this particular threat group, but I didn’t yet have enough information to draw any solid conclusions.
DomainTools says the Justy John email address is tied to more than two dozen domains registered since 2012, but we can find hundreds more phishing domains and related email addresses simply by pivoting on details in the registration records for these Justy John domains. For example, the street address used by the Justy John domain axisupdate[.]net — 7902 Pelleaux Road in Knoxville, TN — also appears in the registration records for accountauthenticate[.]com, acctlogin[.]biz, and loginaccount[.]biz, all of which at one point included the email address rsmith60646@gmail.com.
That Rsmith Gmail address is connected to the 2012 phishing domain alibala[.]biz (one character off of the Chinese e-commerce giant alibaba.com, with a different top-level domain of .biz). A search in DomainTools on the phone number in those domain records — 1.7736491613 — reveals even more phishing domains as well as the Nigerian phone number “2348062918302” and the email address michsmith59@gmail.com.
DomainTools shows michsmith59@gmail.com appears in the registration records for the domain seltrock[.]com, which was used in the phishing attack documented in the 2020 Russian blog post mentioned earlier. At this point, we are just two steps away from identifying the threat actor group.
The same Nigerian phone number shows up in dozens of domain registrations that reference the email address sebastinekelly69@gmail.com, including 26i3[.]net, costamere[.]com, danagruop[.]us, and dividrilling[.]com. A Web search on any of those domains finds they were indexed in an “indicator of compromise” list on GitHub maintained by Palo Alto Networks‘ Unit 42 research team.
According to Unit 42, the domains are the handiwork of a vast cybercrime group based in Nigeria that it dubbed “SilverTerrier” back in 2014. In an October 2021 report, Palo Alto said SilverTerrier excels at so-called “business e-mail compromise” or BEC scams, which target legitimate business email accounts through social engineering or computer intrusion activities. BEC criminals use that access to initiate or redirect the transfer of business funds for personal gain.
Palo Alto says SilverTerrier encompasses hundreds of BEC fraudsters, some of whom have been arrested in various international law enforcement operations by Interpol. In 2022, Interpol and the Nigeria Police Force arrested 11 alleged SilverTerrier members, including a prominent SilverTerrier leader who’d been flaunting his wealth on social media for years. Unfortunately, the lure of easy money, endemic poverty and corruption, and low barriers to entry for cybercrime in Nigeria conspire to provide a constant stream of new recruits.
BEC scams were the 7th most reported crime tracked by the FBI’s Internet Crime Complaint Center (IC3) in 2024, generating more than 21,000 complaints. However, BEC scams were the second most costly form of cybercrime reported to the feds last year, with nearly $2.8 billion in claimed losses. In its 2025 Fraud and Control Survey Report, the Association for Financial Professionals found 63 percent of organizations experienced a BEC last year.
Poking at some of the email addresses that spool out from this research reveals a number of Facebook accounts for people residing in Nigeria or in the United Arab Emirates, many of whom do not appear to have tried to mask their real-life identities. Palo Alto’s Unit 42 researchers reached a similar conclusion, noting that although a small subset of these crooks went to great lengths to conceal their identities, it was usually simple to learn their identities on social media accounts and the major messaging services.
Palo Alto said BEC actors have become far more organized over time, and that while it remains easy to find actors working as a group, the practice of using one phone number, email address or alias to register malicious infrastructure in support of multiple actors has made it far more time consuming (but not impossible) for cybersecurity and law enforcement organizations to sort out which actors committed specific crimes.
“We continue to find that SilverTerrier actors, regardless of geographical location, are often connected through only a few degrees of separation on social media platforms,” the researchers wrote.
Palo Alto has published a useful list of recommendations that organizations can adopt to minimize the incidence and impact of BEC attacks. Many of those tips are prophylactic, such as conducting regular employee security training and reviewing network security policies.
But one recommendation — getting familiar with a process known as the “financial fraud kill chain” or FFKC — bears specific mention because it offers the single best hope for BEC victims who are seeking to claw back payments made to fraudsters, and yet far too many victims don’t know it exists until it is too late.

As explained in this FBI primer, the International Financial Fraud Kill Chain is a partnership between federal law enforcement and financial entities whose purpose is to freeze fraudulent funds wired by victims. According to the FBI, viable victim complaints filed with ic3.gov promptly after a fraudulent transfer (generally less than 72 hours) will be automatically triaged by the Financial Crimes Enforcement Network (FinCEN).
The FBI noted in its IC3 annual report (PDF) that the FFKC had a 66 percent success rate in 2024. Viable ic3.gov complaints involve losses of at least $50,000, and include all records from the victim or victim bank, as well as a completed FFKC form (provided by FinCEN) containing victim information, recipient information, bank names, account numbers, location, SWIFT, and any additional information.
Marko Elez, a 25-year-old employee at Elon Musk’s Department of Government Efficiency (DOGE), has been granted access to sensitive databases at the U.S. Social Security Administration, the Treasury and Justice departments, and the Department of Homeland Security. So it should fill all Americans with a deep sense of confidence to learn that Mr. Elez over the weekend inadvertently published a private key that allowed anyone to interact directly with more than four dozen large language models (LLMs) developed by Musk’s artificial intelligence company xAI.
Image: Shutterstock, @sdx15.
On July 13, Mr. Elez committed a code script to GitHub called “agent.py” that included a private application programming interface (API) key for xAI. The inclusion of the private key was first flagged by GitGuardian, a company that specializes in detecting and remediating exposed secrets in public and proprietary environments. GitGuardian’s systems constantly scan GitHub and other code repositories for exposed API keys, and fire off automated alerts to affected users.
Philippe Caturegli, “chief hacking officer” at the security consultancy Seralys, said the exposed API key allowed access to at least 52 different LLMs used by xAI. The most recent LLM in the list was called “grok-4-0709” and was created on July 9, 2025.
Grok, the generative AI chatbot developed by xAI and integrated into Twitter/X, relies on these and other LLMs (a query to Grok before publication shows Grok currently uses Grok-3, which was launched in Feburary 2025). Earlier today, xAI announced that the Department of Defense will begin using Grok as part of a contract worth up to $200 million. The contract award came less than a week after Grok began spewing antisemitic rants and invoking Adolf Hitler.
Mr. Elez did not respond to a request for comment. The code repository containing the private xAI key was removed shortly after Caturegli notified Elez via email. However, Caturegli said the exposed API key still works and has not yet been revoked.
“If a developer can’t keep an API key private, it raises questions about how they’re handling far more sensitive government information behind closed doors,” Caturegli told KrebsOnSecurity.
Prior to joining DOGE, Marko Elez worked for a number of Musk’s companies. His DOGE career began at the Department of the Treasury, and a legal battle over DOGE’s access to Treasury databases showed Elez was sending unencrypted personal information in violation of the agency’s policies.
While still at Treasury, Elez resigned after The Wall Street Journal linked him to social media posts that advocated racism and eugenics. When Vice President J.D. Vance lobbied for Elez to be rehired, President Trump agreed and Musk reinstated him.
Since his re-hiring as a DOGE employee, Elez has been granted access to databases at one federal agency after another. TechCrunch reported in February 2025 that he was working at the Social Security Administration. In March, Business Insider found Elez was part of a DOGE detachment assigned to the Department of Labor.

In April, The New York Times reported that Elez held positions at the U.S. Customs and Border Protection and the Immigration and Customs Enforcement (ICE) bureaus, as well as the Department of Homeland Security. The Washington Post later reported that Elez, while serving as a DOGE advisor at the Department of Justice, had gained access to the Executive Office for Immigration Review’s Courts and Appeals System (EACS).
Elez is not the first DOGE worker to publish internal API keys for xAI: In May, KrebsOnSecurity detailed how another DOGE employee leaked a private xAI key on GitHub for two months, exposing LLMs that were custom made for working with internal data from Musk’s companies, including SpaceX, Tesla and Twitter/X.
Caturegli said it’s difficult to trust someone with access to confidential government systems when they can’t even manage the basics of operational security.
“One leak is a mistake,” he said. “But when the same type of sensitive key gets exposed again and again, it’s not just bad luck, it’s a sign of deeper negligence and a broken security culture.”
The FBI and authorities in The Netherlands this week seized dozens of servers and domains for a hugely popular spam and malware dissemination service operating out of Pakistan. The proprietors of the service, who use the collective nickname “The Manipulaters,” have been the subject of three stories published here since 2015. The FBI said the main clientele are organized crime groups that try to trick victim companies into making payments to a third party.
One of several current Fudtools sites run by the principals of The Manipulators.
On January 29, the FBI and the Dutch national police seized the technical infrastructure for a cybercrime service 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 Dutch authorities said 39 servers and domains abroad were seized, and that the servers contained millions of records from victims worldwide — including at least 100,000 records pertaining to Dutch citizens.
A statement from the U.S. Department of Justice refers to the cybercrime group as Saim Raza, after a pseudonym The Manipulaters communally used to promote their spam, malware and phishing services on social media.
“The Saim Raza-run websites operated as marketplaces that advertised and facilitated the sale of tools such as phishing kits, scam pages and email extractors often used to build and maintain fraud operations,” the DOJ explained.
The core Manipulaters product is 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, to name a few.
The government 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.
“Those payments would instead be redirected to a financial account the perpetrators controlled, resulting in significant losses to victims,” the DOJ wrote. “These tools were also used to acquire victim user credentials and utilize those credentials to further these fraudulent schemes. The seizure of these domains is intended to disrupt the ongoing activity of these groups and stop the proliferation of these tools within the cybercriminal community.”

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.
We caught up with The Manipulaters again in 2021, with a story that found the core employees had started a web coding company in Lahore called WeCodeSolutions — presumably as a way to account for their considerable Heartsender income. That piece examined how WeCodeSolutions employees had all doxed themselves on Facebook by posting pictures from company parties each year featuring a large cake with the words FudCo written in icing.
A follow-up story last year about The Manipulaters prompted messages from various WeCodeSolutions employees who pleaded with this publication to remove stories about them. The Saim Raza identity told KrebsOnSecurity they were recently released from jail after being arrested and charged by local police, although they declined to elaborate on the charges.
The Manipulaters never seemed to care much about protecting their own identities, so it’s not surprising that they were unable or unwilling to protect their own customers. In an analysis released last year, 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.
Almost every year since their founding, The Manipulaters have posted a picture of a FudCo cake from a company party celebrating its anniversary.
DomainTools also uncovered evidence that the computers used by The Manipulaters were all infected with the same password-stealing malware, and that vast numbers of credentials were stolen from the group and sold online.
“Ironically, the Manipulaters may create more short-term risk to their own customers than law enforcement,” DomainTools wrote. “The data table ‘User Feedbacks’ (sic) exposes what appear to be customer authentication tokens, user identifiers, and even a customer support request that exposes root-level SMTP credentials–all visible by an unauthenticated user on a Manipulaters-controlled domain.”
Police in The Netherlands said the investigation into the owners and customers of the service is ongoing.
“The Cybercrime Team is on the trail of a number of buyers of the tools,” the Dutch national police said. “Presumably, these buyers also include Dutch nationals. The investigation into the makers and buyers of this phishing software has not yet been completed with the seizure of the servers and domains.”
U.S. authorities this week also joined law enforcement in Australia, France, Greece, Italy, Romania and Spain in seizing a number of domains for several long-running cybercrime forums and services, including Cracked and Nulled. According to a statement from the European police agency Europol, the two communities attracted more than 10 million users in total.
Other domains seized as part of “Operation Talent” included Sellix, an e-commerce platform that was frequently used by cybercrime forum members to buy and sell illicit goods and services.
Cybercriminals are selling hundreds of thousands of credential sets stolen with the help of a cracked version of Acunetix, a powerful commercial web app vulnerability scanner, new research finds. The cracked software is being resold as a cloud-based attack tool by at least two different services, one of which KrebsOnSecurity traced to an information technology firm based in Turkey.
Araneida Scanner.
Cyber threat analysts at Silent Push said they recently received reports from a partner organization that identified an aggressive scanning effort against their website using an Internet address previously associated with a campaign by FIN7, a notorious Russia-based hacking group.
But on closer inspection they discovered the address contained an HTML title of “Araneida Customer Panel,” and found they could search on that text string to find dozens of unique addresses hosting the same service.
It soon became apparent that Araneida was being resold as a cloud-based service using a cracked version of Acunetix, allowing paying customers to conduct offensive reconnaissance on potential target websites, scrape user data, and find vulnerabilities for exploitation.
Silent Push also learned Araneida bundles its service with a robust proxy offering, so that customer scans appear to come from Internet addresses that are randomly selected from a large pool of available traffic relays.
The makers of Acunetix, Texas-based application security vendor Invicti Security, confirmed Silent Push’s findings, saying someone had figured out how to crack the free trial version of the software so that it runs without a valid license key.
“We have been playing cat and mouse for a while with these guys,” said Matt Sciberras, chief information security officer at Invicti.
Silent Push said Araneida is being advertised by an eponymous user on multiple cybercrime forums. The service’s Telegram channel boasts nearly 500 subscribers and explains how to use the tool for malicious purposes.
In a “Fun Facts” list posted to the channel in late September, Araneida said their service was used to take over more than 30,000 websites in just six months, and that one customer used it to buy a Porsche with the payment card data (“dumps”) they sold.
Araneida Scanner’s Telegram channel bragging about how customers are using the service for cybercrime.
“They are constantly bragging with their community about the crimes that are being committed, how it’s making criminals money,” said Zach Edwards, a senior threat researcher at Silent Push. “They are also selling bulk data and dumps which appear to have been acquired with this tool or due to vulnerabilities found with the tool.”
Silent Push also found a cracked version of Acunetix was powering at least 20 instances of a similar cloud-based vulnerability testing service catering to Mandarin speakers, but they were unable to find any apparently related sales threads about them on the dark web.
Rumors of a cracked version of Acunetix being used by attackers surfaced in June 2023 on Twitter/X, when researchers first posited a connection between observed scanning activity and Araneida.
According to an August 2023 report (PDF) from the U.S. Department of Health and Human Services (HHS), Acunetix (presumably a cracked version) is among several tools used by APT 41, a prolific Chinese state-sponsored hacking group.
Silent Push notes that the website where Araneida is being sold — araneida[.]co — first came online in February 2023. But a review of this Araneida nickname on the cybercrime forums shows they have been active in the criminal hacking scene since at least 2018.
A search in the threat intelligence platform Intel 471 shows a user by the name Araneida promoted the scanner on two cybercrime forums since 2022, including Breached and Nulled. In 2022, Araneida told fellow Breached members they could be reached on Discord at the username “Ornie#9811.”
According to Intel 471, this same Discord account was advertised in 2019 by a person on the cybercrime forum Cracked who used the monikers “ORN” and “ori0n.” The user “ori0n” mentioned in several posts that they could be reached on Telegram at the username “@sirorny.”

The Sirorny Telegram identity also was referenced as a point of contact for a current user on the cybercrime forum Nulled who is selling website development services, and who references araneida[.]co as one of their projects. That user, “Exorn,” has posts dating back to August 2018.
In early 2020, Exorn promoted a website called “orndorks[.]com,” which they described as a service for automating the scanning for web-based vulnerabilities. A passive DNS lookup on this domain at DomainTools.com shows that its email records pointed to the address ori0nbusiness@protonmail.com.
Constella Intelligence, a company that tracks information exposed in data breaches, finds this email address was used to register an account at Breachforums in July 2024 under the nickname “Ornie.” Constella also finds the same email registered at the website netguard[.]codes in 2021 using the password “ceza2003” [full disclosure: Constella is currently an advertiser on KrebsOnSecurity].
A search on the password ceza2003 in Constella finds roughly a dozen email addresses that used it in an exposed data breach, most of them featuring some variation on the name “altugsara,” including altugsara321@gmail.com. Constella further finds altugsara321@gmail.com was used to create an account at the cybercrime community RaidForums under the username “ori0n,” from an Internet address in Istanbul.
According to DomainTools, altugsara321@gmail.com was used in 2020 to register the domain name altugsara[.]com. Archive.org’s history for that domain shows that in 2021 it featured a website for a then 18-year-old Altuğ Şara from Ankara, Turkey.
Archive.org’s recollection of what altugsara dot com looked like in 2021.
LinkedIn finds this same altugsara[.]com domain listed in the “contact info” section of a profile for an Altug Sara from Ankara, who says he has worked the past two years as a senior software developer for a Turkish IT firm called Bilitro Yazilim.
Neither Altug Sara nor Bilitro Yazilim responded to requests for comment.
Invicti’s website states that it has offices in Ankara, but the company’s CEO said none of their employees recognized either name.
“We do have a small team in Ankara, but as far as I know we have no connection to the individual other than the fact that they are also in Ankara,” Invicti CEO Neil Roseman told KrebsOnSecurity.
Researchers at Silent Push say despite Araneida using a seemingly endless supply of proxies to mask the true location of its users, it is a fairly “noisy” scanner that will kick off a large volume of requests to various API endpoints, and make requests to random URLs associated with different content management systems.
What’s more, the cracked version of Acunetix being resold to cybercriminals invokes legacy Acunetix SSL certificates on active control panels, which Silent Push says provides a solid pivot for finding some of this infrastructure, particularly from the Chinese threat actors.
