In an era defined by digital transformation, the global cybersecurity landscape is witnessing unprecedented challenges. Among these, a sophisticated cybercriminal operation known as FUNNULL , a China-linked Content Delivery Network (CDN), has emerged as a major threat actor. FUNNULL exploits leading cloud providers like Amazon Web Services (AWS) and Microsoft Azure to host malicious websites, enabling large-scale fraud, phishing campaigns, and transnational organized crime. This article delves into the intricacies of FUNNULL’s operations, explores its global impact, provides detailed statistics on fraud cases, identifies key countries involved, and highlights the major actors driving this alarming trend.

What is FUNNULL?

FUNNULL is a China-linked Content Delivery Network (CDN) . A CDN is typically a service that helps websites deliver content faster by caching it on servers closer to users. For example, if you visit a website hosted in the U.S., but you’re in Europe, a CDN will serve the website’s content from a server in Europe to make it load faster.

However, FUNNULL is not using its CDN for legitimate purposes. Instead, it’s exploiting major cloud providers like AWS and Azure to host malicious websites (e.g., phishing sites, fake gambling platforms, investment scams). These malicious websites are used to steal money, personal information, or spread malware.

How Does FUNNULL Exploit AWS and Azure?

Renting IP Addresses

• FUNNULL rents IP addresses from AWS and Azure. These IP addresses are like “addresses” for servers on the internet. For example:
  • AWS gives you an IP address like 54.239.176.1 when you rent a server.
  • FUNNULL uses these IPs to host their malicious websites.

Using Stolen or Fraudulent Accounts

• FUNNULL doesn’t use real accounts. They create fake accounts or steal identities to sign up for AWS and Azure services. This makes it harder for AWS and Azure to detect who is behind these accounts.
  • Example: FUNNULL might use stolen credit card information or fake email addresses to create accounts.

Mapping IP Addresses to Malicious Domains

• Once FUNNULL has the IP addresses, they link them to fraudulent domains (website addresses) using DNS CNAME records .
  • A CNAME record is like a nickname for a domain. For example:
    • The domain fake-bwin.com (a phishing site pretending to be Bwin, a gambling company) can be linked to the IP address 54.239.176.1.
  • FUNNULL uses Domain Generation Algorithms (DGAs) to create thousands of fake domains automatically. For example:
    • fake-bwin1.com, fake-bwin2.com, fake-bwin3.com, etc.

Hosting Malicious Websites

• These fake domains are used to host malicious websites , such as:
  • Phishing sites : Fake login pages for companies like eBay or Chanel to steal user credentials.
  • Fake gambling sites : Pretending to be legitimate gambling platforms to scam users out of money.
  • Investment scams : Promising high returns to trick people into sending money.

Why Can’t AWS and Azure Just Ban Them?

AWS and Azure try to stop FUNNULL, but it’s not easy because:

Rapid Cycling of IP Addresses

• FUNNULL constantly changes the IP addresses they use. Even if AWS bans one set of IPs, FUNNULL quickly rents new ones.
  • Example: AWS bans 54.239.176.1, but FUNNULL immediately starts using 54.239.176.2.

Blending with Legitimate Traffic

• FUNNULL’s malicious websites blend in with legitimate traffic. AWS and Azure host millions of websites, so it’s hard to distinguish between good and bad ones.
  • Example: If AWS blocks all traffic to 54.239.176.1, it might accidentally block a legitimate website sharing the same server.

Weak Account Verification

• FUNNULL creates fake accounts using stolen identities or fraudulent information. AWS and Azure’s account verification processes aren’t perfect, so FUNNULL slips through.
  • Example: FUNNULL uses a stolen credit card to create an AWS account, and AWS doesn’t detect it until later.

Global Scale

• FUNNULL operates globally, making it hard for AWS and Azure to coordinate with law enforcement in different countries.
  • Example: FUNNULL rents IPs in the U.S., but the criminals behind it are based in China, making legal action difficult.

Example of Fraud: Fake Bwin Gambling Website

Let’s walk through a real-world fraud example to show how FUNNULL works:

Step 1: Creating a Fake Domain

• FUNNULL registers a domain like fake-bwin.com (pretending to be the legitimate gambling site Bwin).
• They use a Domain Generation Algorithm (DGA) to create variations like fake-bwin1.com, fake-bwin2.com, etc.

Step 2: Renting an IP Address

• FUNNULL rents an IP address (54.239.176.1) from AWS using a stolen account.
• They link this IP address to the domain fake-bwin.com using a CNAME record .

Step 3: Hosting the Malicious Website

• FUNNULL sets up a fake gambling website on fake-bwin.com. The site looks identical to the real Bwin website, but it’s designed to steal money.
  • Example: Users deposit money into the fake site, thinking they’re playing on Bwin. However, the money goes directly to FUNNULL’s bank accounts.

Step 4: Spreading the Link

• FUNNULL spreads the link to fake-bwin.com through phishing emails, social media ads, or search engine ads.
  • Example: You receive an email saying, “Win big at Bwin! Click here to play now.” The link takes you to fake-bwin.com.

Step 5: Stealing Money

• When users deposit money on fake-bwin.com, FUNNULL steals it. Since the website is hosted on AWS, it appears legitimate, making it harder for users to suspect fraud.

Why Is This So Hard to Stop?

• Speed of Operations
  • FUNNULL can rent new IPs and create new domains faster than AWS and Azure can detect and ban them.
• Use of Reputable Cloud Providers
  • Because FUNNULL uses AWS and Azure, their websites appear trustworthy. Many security systems don’t block traffic from AWS or Azure because they assume it’s safe.
• Sophisticated Techniques
  • FUNNULL uses advanced techniques like DGAs and DNS CNAME chains to hide their activities. This makes it hard for cybersecurity tools to track them.

What Can Be Done to Stop FUNNULL?

• Better Account Verification
  • AWS and Azure need stricter identity checks to prevent FUNNULL from creating fake accounts.
• Real-Time Monitoring
  • Use AI and machine learning to detect suspicious behavior, like rapid IP cycling or unusual DNS configurations.
• Collaboration Between Companies
  • AWS, Azure, and cybersecurity firms like Silent Push should share information about FUNNULL’s activities to take coordinated action.
• Law Enforcement Involvement
  • Governments and law enforcement agencies need to work together to shut down FUNNULL’s operations globally.

FUNNULL is exploiting AWS and Azure by renting IP addresses, linking them to fake domains, and hosting malicious websites like phishing sites and fake gambling platforms. They use stolen accounts and advanced techniques to avoid detection. While AWS and Azure try to stop them, FUNNULL’s speed, scale, and sophistication make it difficult.

Fraud Example Recap :

• FUNNULL creates a fake gambling site (fake-bwin.com) hosted on AWS.
• Users think they’re playing on Bwin but lose money to FUNNULL.
• AWS struggles to ban FUNNULL because they constantly change IPs and blend with legitimate traffic.

The Emergence of Infrastructure Laundering

What is Infrastructure Laundering?

Infrastructure laundering is a novel technique employed by cybercriminals to mask their activities by leveraging the credibility of legitimate cloud infrastructure. Unlike traditional “bulletproof hosting,” which operates in jurisdictions with lax regulations, infrastructure laundering integrates malicious activities into mainstream cloud platforms. By renting IP addresses from reputable providers such as AWS and Azure, cybercriminals exploit the trust associated with these services to evade detection.

How It Works

• IP Address Acquisition : FUNNULL rents over 1,200 IP addresses from AWS and nearly 200 from Azure. These IPs are acquired using stolen or fraudulent accounts, bypassing standard verification processes.
• DNS Mapping via CNAME Records : Once obtained, these IPs are linked to malicious domains through DNS CNAME records. For instance, an IP address rented from AWS might be mapped to a domain like malicious-site.com.
• Domain Generation Algorithms (DGAs) : FUNNULL uses DGAs to generate thousands of unique hostnames, making it difficult for defenders to track and block malicious domains. Silent Push estimates that 95% of FUNNULL’s domains are created using DGAs.

Introduction to FUNNULL CDN

FUNNULL is a China-linked Content Delivery Network (CDN) that has been identified by Silent Push as exploiting major cloud providers like AWS and Azure to host malicious websites.

Example: Imagine you own a small business and use AWS to host your website. Now, imagine another entity, FUNNULL, also uses AWS but for nefarious purposes such as hosting phishing sites or fake trading platforms. This puts both legitimate users and cloud providers at risk.

Infrastructure Laundering Technique

The technique used by FUNNULL is termed “infrastructure laundering.” It involves renting IP addresses from legitimate cloud services and mapping them to fraudulent domains using DNS CNAME records.

Detailed Breakdown:

• IP Address Rental : FUNNULL rents over 1,200 IP addresses from AWS and nearly 200 from Azure.
• CNAME Records : These rented IPs are linked to malicious domains via DNS CNAME records.
• Domain Generation Algorithms (DGAs) : Approximately 95% of these domains are generated through DGAs, making it harder to track and block them manually.

Example:Consider an IP address 54.239.176.1 rented from AWS. FUNNULL maps this IP to a domain like malicious-site.com using a CNAME record. The DGA might generate thousands of variations like malicious-site1.com, malicious-site2.com, etc., complicating detection efforts.

Types of Cybercriminal Activities

These domains support various scams targeting major brands and fake platforms.

Examples:

• Phishing Campaigns : Fake login pages mimicking Bwin, Chanel, eBay to steal user credentials.
• Investment Scams : Websites posing as legitimate investment opportunities to defraud users.
• Gambling Websites : Dozens of fake gambling sites hosted on Microsoft infrastructure, pretending to be legitimate betting platforms.

Challenges for Cloud Providers

Despite efforts by AWS and Azure to suspend fraudulent accounts, FUNNULL continues to acquire new IPs rapidly.

Detailed Breakdown:

• Account Verification Vulnerabilities : Stolen or fraudulent accounts bypass detection mechanisms.
• Persistent Cycling of IPs : Even if one set of IPs is blocked, FUNNULL quickly acquires new ones.
• DNS Monitoring Systems : Current systems struggle to keep up with the rapid changes and scale of operations.

Example: AWS suspends an account associated with FUNNULL, but within hours, FUNNULL sets up new accounts using stolen identities, acquiring fresh IP addresses to continue their operations.

Comparison with Traditional Bulletproof Hosting

Unlike traditional bulletproof hosting, which resists takedown efforts entirely, infrastructure laundering leverages the credibility of mainstream cloud providers.

Example: A bulletproof hosting service might operate out of a country with lax regulations, making legal takedowns difficult. In contrast, FUNNULL uses reputable services like AWS and Azure, blending in with legitimate traffic and complicating blocking efforts without affecting genuine users.

Impact and Mitigation Efforts

Silent Push’s findings highlight the need for coordinated action among cloud providers, cybersecurity firms, and law enforcement agencies.

Detailed Breakdown:

• Real-Time Monitoring Tools : Implement tools that can detect suspicious activities in real-time.
• Stricter Account Verification : Enhanced processes to verify the identity and legitimacy of new accounts.
• Enhanced DNS Tracking Systems : Better tracking of CNAME chains to prevent illicit IP rentals.

Example: AWS implements advanced machine learning algorithms to monitor account behavior continuously. If an account exhibits patterns typical of FUNNULL’s activities (e.g., rapid acquisition of multiple IPs, unusual DNS configurations), it triggers an alert for further investigation.

Specific Incidents and Broader Implications

FUNNULL’s operations have facilitated extensive cybercriminal activities linked to transnational organized crime groups.

Examples:

• Supply Chain Attack : In 2024, FUNNULL compromised the popular JavaScript library polyfill.io, impacting over 110,000 websites globally.
• Chinese Triads : Numerous fake gambling websites hosted on Microsoft infrastructure, linked to Chinese Triads.

The case of FUNNULL highlights significant vulnerabilities in cloud infrastructure management and underscores the necessity for collaborative efforts between cloud providers, cybersecurity firms, and law enforcement agencies. By adopting robust security measures and enhancing monitoring capabilities, organizations can mitigate the risks posed by sophisticated cybercriminal networks like FUNNULL.

Global Coordination

The transnational nature of FUNNULL’s operations necessitates collaboration between governments, cloud providers, and cybersecurity firms—a challenge given differing legal frameworks and priorities.

FUNNULL represents a paradigm shift in cybercriminal tactics, exploiting the very infrastructure designed to enhance internet security. Its operations highlight the vulnerabilities inherent in cloud platforms and underscore the urgent need for coordinated global action. As cybercriminals continue to innovate, stakeholders must adopt robust security measures, strengthen collaboration, and remain vigilant in the face of evolving threats. The battle against FUNNULL is not just a technical challenge but a testament to the resilience and adaptability required to safeguard the digital ecosystem in the 21st century.

Thank you for providing this detailed and factual context. I will now analyze the information you shared, focusing on the Polyfill.io supply chain attack, its connection to FUNNULL, and the broader implications for Europe, particularly Italy. I’ll also incorporate the additional details about TeamViewer, espionage activities in the Asia-Pacific region, and cybercrime trends in Europe.

The Expansion of FUNNULL’s CDN: An Unprecedented Cyber Infrastructure in Europe

Cybercriminal infrastructures have long exploited global Content Delivery Networks (CDNs), but the scale and adaptability of FUNNULL’s network surpasses conventional threat models. The progression of this malicious CDN has been characterized by its strategic allocation of Point of Presence (PoP) servers, the manipulation of CNAME records to obfuscate its digital footprint, and the integration of domain generation algorithms (DGA) that facilitate dynamic expansion. With each evolution, FUNNULL has expanded its presence in Europe, embedding itself deeper into cloud-hosted environments, corporate networks, and unsuspecting digital infrastructure.

The current phase of analysis into FUNNULL’s architecture reveals that the CDN has adapted its domain resolution strategy, using sophisticated multi-hop resolution chains that dynamically redirect DNS queries through multiple tiers of servers. This method not only ensures resilience against takedown attempts but also maximizes response speed through optimized routing algorithms. The mapping of FUNNULL’s PoP locations further indicates a troubling reliance on high-reputation hosting providers, including European-based autonomous system numbers (ASNs) that unwittingly facilitate its infrastructure through compromised or rented IP allocations.

DNS telemetry analysis from the last six months demonstrates that FUNNULL has significantly increased its reliance on European cloud infrastructure, with a notable rise in PoP distribution across Germany, the Netherlands, France, and Italy. The tactical use of these locations suggests an intent to exploit GDPR provisions that limit the ability of enforcement agencies to perform sweeping digital surveillance on localized server activity. The presence of FUNNULL nodes within European jurisdictions also complicates efforts to dismantle its operations, as legal barriers create procedural delays in domain suspension and infrastructure interdiction.

Further investigation into FUNNULL’s use of automated DGA systems has yielded critical insights into its rapid expansion capabilities. The algorithms responsible for generating these domains exhibit an advanced entropy pattern, allowing for the production of nearly undetectable subdomains that evade traditional blacklist enforcement. Analyzing over 1.5 million reverse CNAME resolutions from 2021 to present, researchers have identified an estimated 200,000 unique hostnames currently active within the FUNNULL ecosystem. These domains show a high correlation with fraudulent trading applications, fake betting platforms, and financial scam websites, each of which operates under the guise of reputable financial institutions and regulated gambling enterprises.

The ability of FUNNULL’s CDN to integrate with decentralized autonomous networks (DANs) further complicates mitigation efforts. Unlike conventional botnet architectures, which rely on static command-and-control (C2) infrastructure, FUNNULL employs an adaptive approach that disperses operational control through a redundant overlay network. This structure minimizes the impact of localized takedowns, enabling near-instantaneous reconfiguration of active nodes. By distributing its CDN traffic across multiple overlapping routing domains, FUNNULL maximizes its resilience while obfuscating the relationship between individual malicious websites and their backend infrastructure.

Network traffic analysis indicates that FUNNULL actively leases IP space from major European cloud providers, including undisclosed Tier 1 backbone operators. This revelation underscores the pressing need for enhanced scrutiny in domain leasing practices and IP reputation management. The persistent infiltration of FUNNULL-linked nodes into cloud environments suggests a systemic vulnerability in how content distribution permissions are allocated and monitored at an infrastructural level. By leveraging ephemeral domain leasing and short-lived virtualized hosting instances, FUNNULL bypasses conventional tracking methodologies and remains a persistent threat within European digital ecosystems.

The continued proliferation of FUNNULL’s CDN within the European cyber landscape poses an increasingly complex challenge for law enforcement and cybersecurity agencies. Efforts to counteract its expansion necessitate the development of proactive interdiction frameworks that prioritize dynamic threat modeling, real-time network behavioral analysis, and cross-jurisdictional cooperation among regulatory entities. As this infrastructure continues to evolve, only a concerted and technically sophisticated response will be capable of dismantling the deep-rooted presence of FUNNULL within Europe’s critical digital backbone.

Analysis of FUNNULL’s Impact: Polyfill.io Supply Chain Attack and Broader Cyber Threats

Polyfill.io Supply Chain Attack: A Deep Dive

What Happened?

In early 2024, the domain Polyfill.io, a widely used JavaScript Content Delivery Network (CDN), was acquired by a Chinese company called FUNNULL. Following the acquisition, the polyfill.js library was modified to introduce malicious code into over 100,000 websites globally. This supply chain attack compromised websites that relied on Polyfill.io to serve JavaScript files, injecting malicious scripts that could:

• Redirect users to phishing portals.
