Session Hijacking: What it is, how it works, and how to stop it
In this video, we explore session hijacking: how attackers take over a logged-in session without needing your password. A “session” is the logged-in state your browser and a server share after authentication. Session hijacking is when an attacker steals or reuses the session token so the server treats them like you. In this lesson, we’ll walk through what sessions look like in real web apps, the most common ways tokens get exposed, how defenders detect suspicious sessions, and how to harden both the application and the user environment. We’ll also end with a practical response checklist. As you listen, remember this mental model: your password gets you in the door, but the session token is the wristband that lets you move around inside. If someone steals the wristband, they can impersonate you until it’s invalidated.
