Defacing websites refers to the unauthorized alteration of a website's appearance or content. This act is typically carried out by hackers who exploit security vulnerabilities to replace the original content with their own messages, images, or graphics. The motivations behind website defacement can vary, including political statements, vandalism, or simply to demonstrate technical skills. The impact of defacing websites can be significant, as it can damage a company's reputation and erode user trust. Organizations often invest in cybersecurity measures to protect their sites from such attacks, which can involve monitoring for vulnerabilities and implementing security protocols to safeguard against unauthorized access.
