The following are some means that can be used from a technical point of view to spread false information online and manipulate public opinion for political purposes.： ### Automated fake account generation 1. **Botnet technology** -**Principle**: A botnet is formed by controlling a large number of computers (zombie hosts) that are implanted with malicious software. Attackers can use these zombie hosts to create fake network accounts in bulk. These malicious software usually uses system vulnerabilities to infect computers, and then an attacker can remotely control these computers and generate a large number of accounts according to predetermined procedures. -**Example**: Some hacker organizations may attack computers in specific regions or industries, controlling hundreds or thousands of computers to form a botnet. Then use these botnets to generate a large number of social media accounts, such as Weibo, Twitter and other accounts. These accounts often have relatively simple and random avatars and profiles, and do not have the characteristics of real users. Then use these fake accounts to publish various false information, such as fabricating political events, spreading rumors, etc., in an attempt to influence public opinion. 2. **Fake account generation tool** -**Principle**: Some criminals have developed special fake account generation software, which can simulate the process of real user registration and bypass security mechanisms such as website verification codes. It may randomly generate seemingly reasonable user registration information such as name, email address, and mobile phone number, and then quickly register accounts in bulk. -**Example**: Account generation tools developed by some underground teams can create tens of thousands of fake forum accounts in a short period of time. These accounts will be used to post false posts with obvious political leanings on relevant forums, such as discrediting a political figure or promoting an extreme political view, guiding the discussion direction of other users in the forum, and then influencing the public's views on related political topics. ### Information forgery and tampering 1. **Image and video forgery technology** -**Deep forgery technology** -**Principle**: Using deep learning algorithms, through the learning of a large number of image or video data, it is possible to generate seemingly real but actually forged character images or videos. An attacker can migrate one person's facial expressions, movements and other characteristics to another person to create fake video content. For example, using generative confrontation network (GAN) technology, the generator network learns the facial features of real people, and the discriminator network is responsible for distinguishing between real and fake content. Through continuous confrontation training, the generated fake videos become more and more realistic. -**Example**: In the political field, a fake video of a leader's speech may be produced in which the leader says something that is not in line with his true position. Then it spread widely through social media, video platforms and other channels to mislead the public and arouse negative public opinion on the leader's policies or image. -**Image tampering software** -**Principle**: Although some image processing software such as Adobe Photoshop was originally used as a tool for normal image editing, it may also be used by criminals to tamper with image information. They can modify the characters, scenes, texts, etc. in the photos to convey false information. -**Example**: Modify certain slogans in a photo of a political event site, add some inflammatory or misleading text, and then post the modified photo online, claiming to be the real situation at the event site, in order to mislead the public's understanding of the political event and arouse the publicDifferent opinions and fluctuations in public opinion. 2. **Text forgery and tampering** -**Abuse of natural language generation technology** -**Principle**: Natural language generation technology can generate text based on preset templates and rules. Criminals use this technology to write specific programs or use open source language models to generate seemingly reasonable news reports, commentary articles, and other texts based on the false political views they want to spread. These texts may imitate the real news writing style and contain some specific event descriptions, cited data, etc., making it difficult for readers to distinguish the authenticity. -**Example**: Generate a false news report claiming that a certain government is about to implement a policy that seriously harms the interests of the people, and describe in detail the content of the policy and the possible consequences. Through publication on major news websites, social media groups and other channels, public attention and panic about the policy were aroused, which in turn affected the public's attitude and public opinion orientation towards the government. -**Text editing tools** -**Principle**: Simple text editing software such as Microsoft Word can also be used to directly tamper with text content. An attacker can modify the text of published press releases, policy documents, etc., and change the key information in them, such as policy terms, data statistics, etc., to convey a completely different meaning from the original content. -**Example**: Tamper with the economic growth data in an economic development report released by the government, exaggerate or reduce the growth rate, and then spread the tampered report online. This may raise public doubts about the effectiveness of the government's economic policies, and lead to a negative evaluation of the government's economic work by public opinion. ### Information dissemination and diffusion 1. **Social media platform manipulation** -**Algorithm utilization** -**Principle**: The recommendation algorithm of social media platforms aims to push relevant content to users based on their interests, behaviors, etc. The attacker will study these algorithm rules and create fake popularity
