There are such technical means that use Web pages to implant malicious scripts to gain unauthorized access to user device information. Some malicious attackers may implement it in the following ways： 1. **XSS (cross-site script attack)**: By inducing users to operate on a Web page that has been implanted with malicious scripts, when the user visits the Web page, the malicious script will be executed in the user's browser environment, thereby obtaining information such as Cookies, device identification, browsing history, etc. 2. **Exploit Web vulnerabilities**: Find security vulnerabilities in Web applications, such as input verification defects, inject malicious scripts, and then obtain device-related information. In order to prevent such attacks, users should keep their browsers updated with security patches in a timely manner, do not arbitrarily click on links from unknown sources and download unknown files, and treat interactions on Web pages with caution. Website developers also need to take security measures to prevent Web pages from being maliciously implanted with scripts.
