Chống Lừa Đảo

Chống Lừa Đảo, also known as ChongLuaDao or Scam Fighters, is a Vietnamese nonprofit cybersecurity initiative focused on preventing online fraud and helping internet users assess whether websites and digital content are trustworthy. Its work combines community reporting, threat-intelligence data, browser and mobile tools, public education, victim assistance, and cooperation with cybersecurity companies, technology platforms, civil-society organizations, and Vietnamese public institutions. The project emerged during a period when phishing, fake banking domains, malicious applications, recruitment scams, identity theft, ransomware, and other forms of online fraud were becoming increasingly common in Vietnam. It was started by a group of Vietnamese computer-security specialists that included Hieu Minh Ngo, Le Phuoc Hoa, Nguyen Hoang Thang, and Nguyen Hung. Ngo, also known as HieuPC, had previously been convicted in the United States for identity-theft offenses and later became involved in cybersecurity education and community-protection initiatives after returning to Vietnam in August 2020. Other members associated with the project included Nguyen Manh Luat and Pham Tien Manh. Duong Ngoc Thai, a former Google engineer, has been described as a confidential data-security adviser for the project. Chống Lừa Đảo began operations on December 27, 2020, and formally introduced its website and browser extension in early 2021. The extension enabled users to check websites against a community-supported database of dangerous domains and to submit reports. Within the initial period after launch, the project reported thousands of downloads and user-generated reports, as well as the addition of more than 1,000 suspected scam websites to its denylist. The project also shared threat data with organizations including the Anti-Phishing Working Group and later developed cooperation involving PhishTank, Meta, Viettel Cyber Security, Kaspersky, Cisco OpenDNS, CyRadar, and other security providers. The initiative expanded beyond a browser extension. It released or developed Android and iOS applications, maintained frequently updated datasets, and introduced a Facebook Messenger chatbot that allowed users to assess website risks through a conversation interface. Its data and application programming interfaces were made available for use by other security products and platforms. The project has also worked with organizations addressing recruitment fraud, legal information, digital identity, threat intelligence, and online safety. In 2022, its API was incorporated into Twitter's link-screening processes according to the cited reference material, and the project entered a cooperation agreement with Vietnam's Law Library to support anti-fraud assistance. By early 2023, the initiative said its communities across Telegram, Facebook, and browser extensions included more than 300,000 users and that it had assisted more than 11,000 cyber-fraud victims. It reported a database containing approximately 15,000 malicious URLs and identified thousands of fake websites during the first quarter of that year. The project has positioned itself not only as a threat-data provider but also as a public-facing reporting and education service. It has issued warnings about banking-domain impersonation, fake job offers, deepfake-related fraud, ransomware, malicious applications, and automated fraud operations. It has also offered or coordinated free legal-support channels for victims. Public outreach became a larger part of the organization's work in 2023 and 2024. Chống Lừa Đảo conducted information-security workshops, including sessions designed for deaf and hard-of-hearing communities in Hanoi and Ho Chi Minh City. It participated in conferences and policy discussions involving the National Cyber Security Center, the Authority of Information Security, the Vietnam Information Security Association, the Vietnam Blockchain Association, banks, technology companies, and police authorities. At its January 2024 anniversary event, the project reported communities of roughly 500,000 Facebook members and 25,000 Telegram members, along with the detection and handling of more than 20,000 malicious websites. In 2025, Chống Lừa Đảo introduced an artificial-intelligence-based website assessment tool. Unlike a traditional denylist-only model, the tool analyzes submitted websites in real time using characteristics such as page content, source code, and screenshots. The project subsequently added an automated anti-fraud chatbot and a malware-scanning capability aimed particularly at PHP and WordPress websites. The new service reportedly generated a substantial increase in website traffic and processed more than 68,000 analyses within four months. The malware-scanning product reached the final round of the 2025 Vietnam Talent Awards and received third prize at the awards ceremony cited in the reference material. Chống Lừa Đảo remains an active community cybersecurity project rather than a conventional consumer brand. Its core value proposition is rapid, accessible fraud intelligence supported by community participation, technical analysis, public education, and partnerships. Because the available reference material does not provide a verified standalone corporate website, audited financial information, or a complete current leadership roster, those fields are left unspecified.

Chống Lừa Đảo was created in Vietnam by cybersecurity specialists seeking to provide practical defenses against the rapid growth of online fraud. The project was associated with Hieu Minh Ngo, also known as HieuPC, who returned to Vietnam in August 2020 after serving a sentence in the United States for identity-theft offenses. Ngo joined other information-security professionals, including Le Phuoc Hoa, Nguyen Hoang Thang, Nguyen Hung, Nguyen Manh Luat, and Pham Tien Manh, to form the initiative's core team. The project was conceived as a nonprofit effort to warn users about malicious websites, prevent cybercrime, and support people affected by fraud. Operations officially began on December 27, 2020. The project then launched its website and browser extension in early 2021. The extension allowed users to query a website's reputation and submit reports about suspicious domains. The initial response produced thousands of downloads and reports, while the project added more than 1,000 suspected scam websites to its denylist during the period described in the reference material. Vietnix Hosting provided server infrastructure, and the project established threat-data cooperation with the Anti-Phishing Working Group. By October 2021, the website was reportedly receiving approximately 35,000 monthly visits for website-reliability checks. Chống Lừa Đảo subsequently broadened its technical offering. It developed Android and iOS applications, used machine-learning methods to assist analysis, maintained datasets updated through community contributions, and introduced a Facebook Messenger chatbot in September 2021. The chatbot enabled users to check a website through an automated conversation. In November 2021, Ngo announced the creation of ChongLuaDao Social Enterprise Limited Liability Company and became its chief executive, although the project continued to be described as a nonprofit-oriented initiative. The organization grew as fake banking domains, malicious applications, personal-data theft, and other digital scams became more frequent in Vietnam. It called for users to report suspicious activity and to share warnings with family and friends. By early 2023, the project reported more than 300,000 community members across Facebook, Telegram, and browser extensions, assistance to more than 11,000 cyber-fraud victims, a malicious-URL database of approximately 15,000 entries, and 50,000 regular application users. Its feeds and widgets were reportedly used by security products and services associated with Kaspersky, Cisco OpenDNS, Viettel, and CyRadar. Partnerships became an important part of the project's development. In 2022, the project reported integration of its API with Twitter's URL-warning and blocking processes. It also worked with Vietnam's Law Library on user-protection and victim-assistance programs. The project became a supporting member of the Global Anti-Scam Alliance and contributed data to research on online fraud in Vietnam and other Asian markets. In 2023, it cooperated with TopCV on recruitment-fraud detection and with AI SPERA, the developer of the Criminal IP cyber-threat-intelligence search engine, on threat-data sharing. Chống Lừa Đảo and VinCSS also signed a partnership involving cybersecurity education, identity and authentication technology, and efforts to strengthen Vietnam's digital defenses. Public education expanded during 2023 and 2024. The team issued warnings about ransomware, deepfake videos, impersonation schemes, fake jobs, fraudulent banking and investment websites, and other scams. It held workshops in Hanoi and Ho Chi Minh City for deaf and hard-of-hearing audiences and participated in conferences involving Vietnamese cybersecurity authorities, banks, technology companies, and civil-society groups. In late 2023, its products received recognition in the community-contribution category of the Vietnamese Talent Awards. At a January 2024 anniversary event in Ho Chi Minh City, the project reported 500,000 Facebook members, 25,000 Telegram members, and more than 20,000 malicious websites detected or handled. During 2024, representatives took part in regional and domestic discussions on online scams, human trafficking connected to scam operations, artificial intelligence, financial crime, and cyber defense. Hieu Minh Ngo participated in a Mekong-U.S. Partnership dialogue in Bangkok, while the team presented at a Vietnamese conference on protecting people and customers from online fraud. Chống Lừa Đảo also appeared at the Smart Banking 2024 exhibition and at cybersecurity discussions organized by Positive Technologies and Ho Chi Minh City police in cooperation with the Vietnam Blockchain Association. In April 2025, the organization launched an AI-powered website-checking tool. The system was designed to assess websites that were not already present in the existing database by examining their content, source code, and screenshots. The service combined browser-side real-time machine learning with an AI-agent mode and later added an automated fraud-prevention chatbot. The project also developed a PHP and WordPress malware scanner. The new tools reportedly processed more than 68,000 analyses in four months, and the malware-scanning product won third prize at the 2025 Vietnam Talent Awards. Chống Lừa Đảo is therefore best understood as an active Vietnamese anti-fraud and cybersecurity initiative whose model combines community intelligence, automated analysis, partnerships, and public-interest education.
