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.

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.

In an effort to blend in and make their malicious traffic tougher to block, hosting firms catering to cybercriminals in China and Russia increasingly are funneling their operations through major U.S. cloud providers. Research published this week on one such outfit — a sprawling network tied to Chinese organized crime gangs and aptly named “Funnull” — highlights a persistent whac-a-mole problem facing cloud services.

In October 2024, the security firm Silent Push published a lengthy analysis of how Amazon AWS and Microsoft Azure were providing services to Funnull, a two-year-old Chinese content delivery network that hosts a wide variety of fake trading apps, pig butchering scams, gambling websites, and retail phishing pages.

Funnull made headlines last summer after it acquired the domain name polyfill[.]io, previously the home of a widely-used open source code library that allowed older browsers to handle advanced functions that weren’t natively supported. There were still tens of thousands of legitimate domains linking to the Polyfill domain at the time of its acquisition, and Funnull soon after conducted a supply-chain attack that redirected visitors to malicious sites.

Silent Push’s October 2024 report found a vast number of domains hosted via Funnull promoting gambling sites that bear 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 Lazarus Group.

In 2023, Suncity’s CEO was sentenced to 18 years in prison on charges of fraud, illegal gambling, and “triad offenses,” i.e. working with Chinese transnational organized crime syndicates. Suncity is alleged to have built an underground banking system that laundered billions of dollars for criminals.

It is likely the gambling sites coming through Funnull are abusing top casino brands as part of their money laundering schemes. In reporting on Silent Push’s October report, TechCrunch obtained a comment from Bwin, one of the casinos being advertised en masse through Funnull, and Bwin said those websites did not belong to them.

Gambling is illegal in China except in Macau, a special administrative region of China. Silent Push researchers say Funnull may be helping online gamblers in China evade the Communist party’s “Great Firewall,” which blocks access to gambling destinations.

Silent Push’s Zach Edwards said that upon revisiting Funnull’s infrastructure again this month, they found dozens of the same Amazon and Microsoft cloud Internet addresses still forwarding Funnull traffic through a dizzying chain of auto-generated domain names before redirecting malicious or phishous websites.

Edwards said Funnull is a textbook example of an increasing trend Silent Push calls “infrastructure laundering,” wherein crooks selling cybercrime services will relay some or all of their malicious traffic through U.S. cloud providers.

“It’s crucial for global hosting companies based in the West to wake up to the fact that extremely low quality and suspicious web hosts based out of China are deliberately renting IP space from multiple companies and then mapping those IPs to their criminal client websites,” Edwards told KrebsOnSecurity. “We need these major hosts to create internal policies so that if they are renting IP space to one entity, who further rents it to host numerous criminal websites, all of those IPs should be reclaimed and the CDN who purchased them should be banned from future IP rentals or purchases.”

Reached for comment, Amazon referred this reporter to a statement Silent Push included in a report released today. Amazon said AWS was already aware of the Funnull addresses tracked by Silent Push, and that it had suspended all known accounts linked to the activity.

Amazon said that contrary to implications in the Silent Push report, it has every reason to aggressively police its network against this activity, noting the accounts tied to Funnull used “fraudulent methods to temporarily acquire infrastructure, for which it never pays. Thus, AWS incurs damages as a result of the abusive activity.”

“When AWS’s automated or manual systems detect potential abuse, or when we receive reports of potential abuse, we act quickly to investigate and take action to stop any prohibited activity,” Amazon’s statement continues. “In the event anyone suspects that AWS resources are being used for abusive activity, we encourage them to report it to AWS Trust & Safety using the report abuse form. In this case, the authors of the report never notified AWS of the findings of their research via our easy-to-find security and abuse reporting channels. Instead, AWS first learned of their research from a journalist to whom the researchers had provided a draft.”

Microsoft likewise said it takes such abuse seriously, and encouraged others to report suspicious activity found on its network.

“We are committed to protecting our customers against this kind of activity and actively enforce acceptable use policies when violations are detected,” Microsoft said in a written statement. “We encourage reporting suspicious activity to Microsoft so we can investigate and take appropriate actions.”

Richard Hummel is threat intelligence lead at NETSCOUT. Hummel said it used to be that “noisy” and frequently disruptive malicious traffic — such as automated application layer attacks, and “brute force” efforts to crack passwords or find vulnerabilities in websites — came mostly from botnets, or large collections of hacked devices.

But he said the vast majority of the infrastructure used to funnel this type of traffic is now proxied through major cloud providers, which can make it difficult for organizations to block at the network level.

“From a defenders point of view, you can’t wholesale block cloud providers, because a single IP can host thousands or tens of thousands of domains,” Hummel said.

In May 2024, KrebsOnSecurity published a deep dive 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. Experts said 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.

Stark’s network has been a favorite of the Russian hacktivist group called NoName057(16), which frequently launches huge distributed denial-of-service (DDoS) attacks against a variety of targets seen as opposed to Moscow. Hummel said NoName’s history suggests they are adept at cycling through new cloud provider accounts, making anti-abuse efforts into a game of whac-a-mole.

“It almost doesn’t matter if the cloud provider is on point and takes it down because the bad guys will just spin up a new one,” he said. “Even if they’re only able to use it for an hour, they’ve already done their damage. It’s a really difficult problem.”

Edwards said Amazon declined to specify whether the banned Funnull users were operating using compromised accounts or stolen payment card data, or something else.

“I’m surprised they wanted to lean into ‘We’ve caught this 1,200+ times and have taken these down!’ and yet didn’t connect that each of those IPs was mapped to [the same] Chinese CDN,” he said. “We’re just thankful Amazon confirmed that account mules are being used for this and it isn’t some front-door relationship. We haven’t heard the same thing from Microsoft but it’s very likely that the same thing is happening.”

Funnull wasn’t always a bulletproof hosting network for scam sites. Prior to 2022, the network was known as Anjie CDN, based in the Philippines. One of Anjie’s properties was a website called funnull[.]app. Loading that domain reveals a pop-up message by the original Anjie CDN owner, who said their operations had been seized by an entity known as Fangneng CDN and ACB Group, the parent company of Funnull.

“After I got into trouble, the company was managed by my family,” the message explains. “Because my family was isolated and helpless, they were persuaded by villains to sell the company. Recently, many companies have contacted my family and threatened them, believing that Fangneng CDN used penetration and mirroring technology through customer domain names to steal member information and financial transactions, and stole customer programs by renting and selling servers. This matter has nothing to do with me and my family. Please contact Fangneng CDN to resolve it.”

In January 2024, the U.S. Department of Commerce issued a proposed rule that would require cloud providers to create a “Customer Identification Program” that includes procedures to collect data sufficient to determine whether each potential customer is a foreign or U.S. person.

According to the law firm Crowell & Moring LLP, the Commerce rule also would require “infrastructure as a service” (IaaS) providers to report knowledge of any transactions with foreign persons that might allow the foreign entity to train a large AI model with potential capabilities that could be used in malicious cyber-enabled activity.

“The proposed rulemaking has garnered global attention, as its cross-border data collection requirements are unprecedented in the cloud computing space,” Crowell wrote. “To the extent the U.S. alone imposes these requirements, there is concern that U.S. IaaS providers could face a competitive disadvantage, as U.S. allies have not yet announced similar foreign customer identification requirements.”

It remains unclear if the new White House administration will push forward with the requirements. The Commerce action was mandated as part of an executive order President Trump issued a day before leaving office in January 2021.

Federal authorities have arrested and indicted a 20-year-old U.S. Army soldier on suspicion of being Kiberphant0m, a cybercriminal who has been selling and leaking sensitive customer call records stolen earlier this year from AT&T and Verizon. As first reported by KrebsOnSecurity last month, the accused is a communications specialist who was recently stationed in South Korea.

Cameron John Wagenius was arrested near the Army base in Fort Hood, Texas on Dec. 20, after being indicted on two criminal counts of unlawful transfer of confidential phone records.

The sparse, two-page indictment (PDF) doesn’t reference specific victims or hacking activity, nor does it include any personal details about the accused. But a conversation with Wagenius’ mother — Minnesota native Alicia Roen — filled in the gaps.

Roen said that prior to her son’s arrest he’d acknowledged being associated with Connor Riley Moucka, a.k.a. “Judische,” a prolific cybercriminal from Canada who was arrested in late October for stealing data from and extorting dozens of companies that stored data at the cloud service Snowflake.

In an interview with KrebsOnSecurity, Judische said he had no interest in selling the data he’d stolen from Snowflake customers and telecom providers, and that he preferred to outsource that to Kiberphant0m and others. Meanwhile, Kiberphant0m claimed in posts on Telegram that he was responsible for hacking into at least 15 telecommunications firms, including AT&T and Verizon.

On November 26, KrebsOnSecurity published a story that followed a trail of clues left behind by Kiberphantom indicating he was a U.S. Army soldier stationed in South Korea.

Ms. Roen said Cameron worked on radio signals and network communications at an Army base in South Korea for the past two years, returning to the United States periodically. She said Cameron was always good with computers, but that she had no idea he might have been involved in criminal hacking.

“I never was aware he was into hacking,” Roen said. “It was definitely a shock to me when we found this stuff out.”

Ms. Roen said Cameron joined the Army as soon as he was of age, following in his older brother’s footsteps.

“He and his brother when they were like 6 and 7 years old would ask for MREs from other countries,” she recalled, referring to military-issued “meals ready to eat” food rations. “They both always wanted to be in the Army. I’m not sure where things went wrong.”

Immediately after news broke of Moucka’s arrest, Kiberphant0m posted on the hacker community BreachForums what they claimed were the AT&T call logs for President-elect Donald J. Trump and for Vice President Kamala Harris.

“In the event you do not reach out to us @ATNT all presidential government call logs will be leaked,” Kiberphant0m threatened, signing their post with multiple “#FREEWAIFU” tags. “You don’t think we don’t have plans in the event of an arrest? Think again.”

Kiberphant0m posting what he claimed was a “data schema” stolen from the NSA via AT&T.

On that same day, Kiberphant0m posted what they claimed was the “data schema” from the U.S. National Security Agency.

On Nov. 5, Kiberphant0m offered call logs stolen from Verizon’s push-to-talk (PTT) customers — mainly U.S. government agencies and emergency first responders. On Nov. 9, Kiberphant0m posted a sales thread on BreachForums offering a “SIM-swapping” service targeting Verizon PTT customers. In a SIM-swap, fraudsters use credentials that are phished or stolen from mobile phone company employees to divert a target’s phone calls and text messages to a device they control.

The profile photo on Wagenius’ Facebook page was deleted within hours of my Nov. 26 story identifying Kiberphant0m as a likely U.S. Army soldier. Still, many of his original profile photos remain, including several that show Wagenius in uniform while holding various Army-issued weapons.

November’s story on Kiberphant0m cited his own Telegram messages saying he maintained a large botnet that was used for distributed denial-of-service (DDoS) attacks to knock websites, users and networks offline. In 2023, Kiberphant0m sold remote access credentials for a major U.S. defense contractor.

Allison Nixon, chief research officer at the New York-based cybersecurity firm Unit 221B, helped track down Kiberphant0m’s real life identity. Nixon was among several security researchers who faced harassment and specific threats of violence from Judische and his associates.

“Anonymously extorting the President and VP as a member of the military is a bad idea, but it’s an even worse idea to harass people who specialize in de-anonymizing cybercriminals,” Nixon told KrebsOnSecurity. She said the investigation into Kiberphant0m shows that law enforcement is getting better and faster at going after cybercriminals — especially those who are actually living in the United States.

“Between when we, and an anonymous colleague, found his opsec mistake on November 10th to his last Telegram activity on December 6, law enforcement set the speed record for the fastest turnaround time for an American federal cyber case that I have witnessed in my career,” she said.

Nixon asked to share a message for all the other Kiberphant0ms out there who think they can’t be found and arrested.

“I know that young people involved in cybercrime will read these articles,” Nixon said. “You need to stop doing stupid shit and get a lawyer. Law enforcement wants to put all of you in prison for a long time.”

The indictment against Wagenius was filed in Texas, but the case has been transferred to the U.S. District Court for the Western District of Washington in Seattle.
