Direct Answer
Session hijacking is when an attacker takes control of your active login session—without needing your password. Instead of logging in, they steal the session data (like cookies) that keeps you logged in and use it to access your account.
Quick Summary
In one sentence:
Session hijacking lets attackers access your accounts without logging in.
In simple terms:
When you log into a website, your device keeps you signed in using session data. If someone steals that data, they can act like you and access your account—without ever entering your password.
Key points:
- Does not require your password
- Uses stolen session data or cookies
- Often happens on insecure networks
