What is Session Hijacking in Cybersecurity?
The exploitation of a valid web session by stealing or predicting the session token that authenticates a user. Attackers obtain session IDs through XSS, network sniffing, or brute force. Once they have a valid token, they impersonate the victim without needing their password.
Why Session Hijacking Matters for Your Cybersecurity Career
Session hijacking bypasses authentication entirely, giving attackers full access to user accounts. Penetration testers test for session management flaws in every web application assessment. Security engineers configure secure cookie flags, session timeouts, and token rotation to prevent hijacking. This attack demonstrates why HTTPS alone is not enough.
