AI-Generated Misinformation Harms Chinese EV and Tech Companies
Criminal networks in China used AI-powered text generation systems to produce and spread mass misinformation about electric vehicle and technology companies, earning revenue from platform engagement metrics. Police arrested two networks and shut down over 8,000 accounts; Ideal Auto reported losses of 5,000 monthly orders and approximately 200 billion yuan in market value during the attack campaign.
What happened
Yantai police arrested two criminal networks that used AI technology to generate and spread mass negative misinformation about Chinese electric vehicle and tech companies. The networks operated approximately 8,000 social media accounts controlled through 30 MCN accounts.
The gangs input keywords into large language models to rapidly generate detailed, inflammatory 'blackmail articles' with false claims about delivery delays, customer complaints, and product defects. They distributed these articles across multiple platforms to earn flow-based rewards without seeking payment from companies or engaging in traditional extortion.
Reported impact
Ideal Auto, Huawei Hongmeng Smart Travel, and Xiaomi reported that negative articles appeared on network platforms starting from July 2025. Ideal Auto's monthly orders fell by more than 5,000 units during the period of negative information outbreak, and the company's total market value evaporated approximately 200 billion yuan.
The misinformation created false public perception and disrupted normal business operations. Competitor companies fell into mutual suspicion and recrimination.
Index analysis
The networks used AI to lower the cost and increase the efficiency of generating false content at scale. A single operator could manage thousands of accounts and generate vast quantities of misleading articles in minimal time, allowing teams of only 2–5 people to earn 200,000–300,000 yuan per month.
Platform flow-based reward mechanisms incentivized the production of sensational and inflammatory content without verification of truthfulness, enabling the networks to profit solely from engagement metrics.
Governance controls
In 2025, the Cyberspace Administration launched a 'Clear the Internet·Addressing AI Technology Abuse' special campaign targeting AI use in water army activities. Yantai police action resulted in shutdown of over 8,000 illegal accounts.
