The web as a new medium is accessed and viewed by hundreds of millions of people all the time.
However, the webpage tampering has become a problem that can not be ignored. In October 2019, for example, the number of websites tampered with in China reached more than 20,000, with the largest share coming from Beijing, Shandong and Guangdong respectively.
Webpage tampering means that those web pages accessed are not real or even wrong, which can bring about minor disruptions to browsing and serious damage to property.
At present, the method of tampering was more and more complex. Some webpages were modified directly by intrusion sites, and some webpages were inserted illegal html and JavaScript code through cross site Scripting or other vulnerabilities. |
