In a live broadcast scenario, the audience may organize malicious activities against the anchor in a variety of ways. These behaviors are usually group, planned, and destructive. The following are common forms of malicious activities and operating logic： **1. Barrage engineering attack** -**Screen-swiping bombing**: Use automated scripts or robot accounts to send repetitive barrage (such as insults and sensitive words), which destroys the real-time interactive atmosphere and may trigger the platform's current-limiting mechanism. -**Keyword pollution**: Through high-frequency triggering of prohibited words on the platform (such as politically sensitive words and pornographic hints), the induction system automatically blocks the live broadcast room. **2. Data manipulation tactics** -**False reporting cluster**: Organize members to centrally report anchor content (such as fictitious vulgarity, infringement and other reasons), and use the loopholes in the platform's review mechanism to implement a crackdown. -**Traffic trap**: By maliciously swiping up the popularity data of the live broadcast room (such as the number of false viewers), it triggers the platform's anti-cheating system to misjudge it as data fraud, resulting in current restrictions or penalties. **3. Social engineering attack chain** -**Spread of human flesh search**: Systematically collect the anchor's personal information (address, contact information, etc.) and post it on a rolling basis in the barrage/comment area, causing panic about the expansion of secondary dissemination. -Cross-platform encirclement**: Establish topic groups on external platforms such as Weibo and post bars, coordinate the implementation of live broadcast room attack time nodes, and cooperate with external public opinion pressure. **4. Economic warfare strategy** -**Gift fraud attack**: Using the platform's refund rules, focus on swiping high-priced gifts to improve the ranking of the live broadcast room and apply for refunds in bulk, resulting in the freezing of the anchor's income. -**Abuse of virtual props**: Malicious use of gifts with visual interference effects (such as full-screen animation effects) to hinder the normal audience viewing experience. **5. Technical penetration attack** -**CDN penetration strike**: Launch a DDoS attack by parsing the streaming address of the live broadcast room, causing the live broadcast to be stuck or interrupted. -**OCR barrage recognition cracking**: Use image recognition technology to capture the barrage content that is not publicly displayed by the anchor, obtain security strategies, and implement countermeasures. **6. Cognitive warfare penetration** - **Semantic pollution attack**: Specific metaphorical vocabulary (such as homophonic forbidden words) is implanted in the barrage to induce the AI review system to misjudge content violations. -**Group psychological manipulation**: Through large-scale barrage rhythm guidance (such as ”anchor gambling“, ”tax evasion", etc.), create public opinion anchors to influence passers-by and audience cognition. **7. Means of ecological niche destruction** - **Competitive product traffic hijacking**: Organization members send competitive product platform drainage information in bulk in the barrage, triggering the platform's automatic blocking mechanism. -**Virtual black public relations**: Fake screenshots of the anchor's inappropriate remarks to spread in the external community, creating a crisis of public opinion and pouring into the live broadcast room. These attacks often show multi-dimensional collaborative characteristics, such as simultaneous barrage attacks, cross-platform reporting, economic fraud, and technological penetration, forming a three-dimensional strike. Some malicious organizations even have a complete division of labor system, including intelligence groups (collecting anchor weaknesses), technical groups (developing attack tools), action groups (performing attacks), and public opinion groups (external momentum building). Understanding these mechanisms helps the platform optimize defense strategies, such as establishing an abnormal behavior correlation analysis model (such as barrage frequency + gift behavior + cross-verification of external public opinion data), rather than a single-dimensional judgment. For anchors, it is necessary to improve their awareness of new attack forms and avoid malicious exploitation of design vulnerabilities in interactive links.
