In the context of the current rapid development of the scientific and technological revolution, cyberspace is increasingly becoming a crucial front in the fight against fake news and the protection of ideological foundations. There, technology serves both as a medium for disseminating misinformation and as an effective "shield" and "weapon" for identifying, preventing, and refuting harmful content.
Technological forms used to spread fake news.
The fundamental shift in today's information environment lies in the movement from traditional, highly selective, and verified institutions to the logic of cross-border social media platforms with optimized interaction algorithms. On TikTok, Facebook, or YouTube, extremist, controversial, or emotionally charged content often spreads rapidly because it triggers strong reactions and quickly attracts the attention of social media users. Meanwhile, constructive content that requires reflection often loses its advantage in the competition for speed and reach.
Taking advantage of this mechanism, hostile and reactionary forces have intensified the dissemination of fake news and misinformation, turning them into tools to serve their schemes of distorting history, slandering leaders, disrupting social perception, and undermining national unity.
To capture target audiences, the "filter bubble" phenomenon is also being abused by platforms, limiting social media users to a narrow, deliberate range of information. Because, when the algorithm detects a user's interest in a particular content, it continues to suggest more similar content, gradually leading them to believe it's the only truth and potentially forming biases. This phenomenon can easily be exploited by malicious actors to manipulate public opinion in a negative direction.
According to Mr. Nguyen Tu Quang, a member of the Executive Board of the National Cybersecurity Association, Deepfake is as dangerous as a kind of "nuclear bomb" of the internet world . It has a devastating impact on social trust and morality.
Building information "green zones"
Besides the dangerous harm caused by the spread of harmful and malicious information on social media due to the use of technology, the appropriate use of technology will provide effective solutions to detect and prevent fake news, harmful and malicious information. AI needs to be used to detect anomalies not only in content but also in the behavior of dissemination.
Mr. Nguyen Le Thanh, founder and CEO of Verichains Security Company, emphasized: “Using AI is not only for analyzing content but, more importantly, for analyzing dissemination behavior such as bot networks, unusual sharing speeds, and coordinated accounts to detect and block information manipulation campaigns early on. The technology also allows for the establishment of an automated fact-checking database and the labeling of warnings and the origin of content directly on the platform.”
According to cybersecurity expert Ngo Minh Hieu (Hieu PC), redesigning content recommendation systems to be multi-dimensional and prioritize verified sources is one of the important technological steps to break down narrow, harmful "information spaces."
Beyond its role in identification and prevention, technology will also open up new ways to produce, distribute, and spread legitimate content more effectively. "In cyberspace, beauty doesn't naturally win simply because it's right; it only wins when it has the competitive edge in the attention-grabbing economy. Therefore, the issue isn't how much correct content there is, but whether that correct content is attractive enough to be chosen," analyzed Mr. Le Quoc Vinh, Chairman of the Board of Directors of Le Media Group.
Therefore, technology needs to be applied to transform accurate but dry values into impactful stories, using the right language and format that users, especially young people, prefer, such as short videos, 30-second clips, or unique products delivered quickly, instead of lengthy, cumbersome articles or products that are difficult to access.
On April 7, 2026, General Secretary and President To Lam signed a decision ratifying the United Nations Convention against Cybercrime (Hanoi Convention), demonstrating Vietnam's strong and consistent commitment to upholding international law, the UN Charter, and multilateralism. This is an important international legal basis for Vietnam to enhance the effectiveness of preventing, detecting, investigating, and prosecuting cybercrime, meeting the requirements of national security and social order in the context of digital transformation and deep international integration. This includes requiring technology corporations such as Meta and Google to comply with local laws instead of evading them under the guise of "community standards."
According to Mr. Nguyen Le Thanh, there needs to be a mechanism to force cross-border platforms to be transparent about their algorithms and how they propose content, at least ensuring that they do not promote violence or incite violence.
Furthermore, building a strong domestic technology ecosystem capable of "self-protection" is an inseparable strategy. Currently, "Make in Vietnam" businesses have made significant progress, effectively addressing areas such as cybersecurity monitoring, email protection, and information security assessment. However, a concerning reality is that the rate of using domestic cybersecurity products in agencies and businesses is currently only around 24.77%.
Mr. Vu Duy Hien, Chief of Office and Deputy Secretary General of the National Cybersecurity Association, emphasized: "To truly master the digital 'green zone,' we need strong support policies to elevate the level from 'partially meeting' to 'mastering the ecosystem,' reducing dependence on core security platforms and global threat analysis tools."
Fake news has the characteristic of "spreading quickly." When an information gap appears, fake news will fill it. "Providing timely, accurate evidence and information gives the public a basis for belief. When people know to rely on these sources, they will not be easily swayed by fake news. Conversely, if reliable sources are lacking, people will be easily misled. If we do this well, we will not only combat deepfake and fake news, but also contribute to building a more civilized society where people are accustomed to relying on truth and evidence. Then, we will not only 'fight' but also 'build,' establishing a solid foundation of awareness for the entire society," Mr. Nguyen Tu Quang analyzed.
The fight against fake news is therefore not just a technological race, but a process of strengthening and building a "digital immune system" for the community. When each citizen becomes a responsible "media citizen" in cyberspace, knowing how to verify information, then all Deepfake tactics or manipulative algorithms will no longer have a place to operate.
