Jane, an ethical hacker, is testing a target organization's web server and website to identify security loopholes. In this process, she copied the entire website and its content on a local drive to…

Session hijacking involves stealing or forging valid session tokens to impersonate an authenticated user, which has nothing to do with copying website content to a local drive.

Website mirroring involves using tools (such as HTTrack or wget) to create a complete local copy of a target website, replicating its directory structure, files, images, and links. This offline copy allows an attacker or ethical hacker to analyze the site's architecture, identify hidden directories, and gather reconnaissance data without generating excessive live traffic. It is a passive information-gathering technique used in the footprinting phase of ethical hacking.

Website defacement is an attack where the attacker alters the visual appearance or content of a live website, which is an active, destructive act rather than a passive copying operation.

Web cache poisoning involves injecting malicious content into a caching server so that other users receive corrupted responses, which is unrelated to locally mirroring a website's structure.
