[Security Agency Discovers 186 Counterfeit AI Website Domains, Involving 27 Brands Including ChatGPT and Claude] According to a report by Cryptopolitan on November 13th, enterprise browser security company Island released a research report discovering 186 counterfeit AI tool domains, involving 27 brands including ChatGPT, Claude, DeepSeek, and Gemini. ChatGPT had the most counterfeited domains (25), followed by Claude (18) and DeepSeek (16). The research found that some counterfeit websites exploit spelling errors when users enter URLs, redirecting them to malicious pages, inducing PowerShell commands through fake Cloudflare verification, or promoting software with browser hijacking capabilities. Furthermore, researchers also discovered 30 browser extensions involved in search hijacking, 17 of which are still in use, with a cumulative user base of approximately 972,000. Island emphasized that the 186 domains do not represent the actual number of infections, and the specific economic losses caused by the attacks have not yet been confirmed.
