The U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) recently imposed sanctions on Funnull Technology Inc., a firm based in the Philippines, along with its administrator Liu Lizhi. These sanctions highlight the company’s role in facilitating elaborate romance baiting scams that have robbed numerous individuals of their hard-earned money, especially in the realm of cryptocurrency fraud. This situation underscores the increasing intersection of online scams, cryptocurrency, and the complexities of international regulation.
Funnull Technology Inc. is alleged to have played a significant part in a network of fraudulent websites that conduct virtual currency investment scams. According to Treasury officials, the activities associated with Funnull have led to approximately $200 million in U.S. victim-reported losses. This staggering figure represents numerous individuals, many of whom have lost an average of over $150,000 each due to these scams.
Initially gaining attention in the cybersecurity realm in June 2024, Funnull was implicated in a supply chain attack involving the widely used Polyfill.io JavaScript library. This precursor to the recent sanctions illustrated the company’s questionable practices and raised red flags about its broader operations. An analysis conducted by cybersecurity experts at Silent Push last year revealed that the infrastructure linked to Funnull has been misused to promote fake trading apps, investment scams, and dubious gambling websites—all underlined by the skepticism surrounding digital currencies.
One notably concerning practice attributed to Funnull is known as “infrastructure laundering.” This practice involves acquiring IP addresses from legitimate cloud service providers, including names like Amazon Web Services (AWS) and Microsoft Azure, which are then utilized to host malicious content and criminal websites. By masking their operations behind the credibility of these well-known providers, cybercriminals can more easily deceive victims and evade capture.
The Treasury outlined the various methods employed by Funnull, including bulk purchases of IP addresses and the automated generation of domain names to perpetuate their scams. The company utilizes domain generation algorithms (DGAs) to create numerous similar domain names, making it easier for scammers to launch multiple websites without drawing immediate attention. Moreover, they supply web design templates that enable criminals to emulate legitimate brands, further enhancing the deceitfulness of these scam websites.
Adding further dimensions to the complexity of their operations, the Treasury alleges that Funnull acquired Polyfill.io with malicious intent. This move allowed them to redirect visitors from legitimate websites to platforms associated with scams or online gambling that may also have ties to Chinese criminal money laundering operations. The scope of these operations is particularly alarming given the growing prevalence of such scams in the digital landscape.
The administrator of Funnull, Liu Lizhi, has also come under scrutiny. The Treasury reported that he possessed numerous documents detailing employee roles and tasks, which included assigning domain names for various fraudulent schemes, ranging from investment fraud to phishing and gambling scams. Such documentation paints a detailed picture of the organized nature of these operations, indicating a well-structured network aimed at exploiting unsuspecting victims.
In a related investigation, the Federal Bureau of Investigation (FBI) unveiled their findings regarding Funnull’s operations. The agency reported identifying 548 unique Canonical Names (CNAME) tied to over 332,000 individual domains linked to Funnull since January 2025. This widespread network of domains suggests that the scale of operations led by Funnull is enormous, with implications that reach far beyond the immediate financial damage inflicted upon individual victims.
Interestingly, data gathered between October 2023 and April 2025 revealed patterns of IP address activity that indicate fraudulent maneuvering across domains using Funnull’s infrastructure. Disturbingly, the FBI found that numerous domains simultaneously transitioned from one IP address to another, often within the same day. This rapid change in digital real estate exemplifies the adaptability of cybercriminals in the face of regulatory scrutiny.
As the digital landscape evolves, so do the tactics employed by scammers. Romance baiting—a trend where fraudsters cultivate romantic relationships online with the intent to deceive victims for financial gain—has gained traction, largely due to the increased use of cryptocurrency. The anonymity and lack of regulation surrounding cryptocurrencies make them an attractive target for opportunistic cybercriminals looking to exploit unwary individuals.
The revelation of the U.S. sanctions against Funnull brings to light the pressing need for vigilance among internet users. Amid the allure of potential gains from cryptocurrency investments and online relationships, individuals must exercise caution and skepticism regarding opportunities and relationships that seem too good to be true. Awareness is key in navigating the treacherous waters of online interactions, particularly when financial transactions are involved.
The sanctions against Funnull and Liu Lizhi serve as a warning to those involved in the digital currency space. Cryptocurrency is becoming increasingly popular, but so are the fraudulent activities that seek to exploit individuals’ trust and naiveté. As a global community, it is essential to foster educational initiatives focused on cybercrime awareness, consumer protection, and digital literacy to mitigate the risks associated with these modern threats.
In conclusion, the sanctions imposed by the U.S. Treasury highlight the urgent and complex nature of combating cybercrime connected to cryptocurrency. Funnull’s role in facilitating significant financial losses and its innovative yet malicious strategies serve as a stark reminder of the dark side of the online world. With financial security increasingly reliant on digital platforms, understanding the risks and adopting vigilant practices is crucial for safeguarding individual interests in this rapidly evolving landscape.
