- Session Fixation: Threat actors force a specific session ID on the victim by generating or obtaining a valid session ID beforehand. When the victim logs in, the attacker can then use the fixed session ID to hijack the session.
- Man-in-the-Middle (MitM) Attacks: Attackers position themselves between the user and the server to intercept and modify traffic. This enables them to capture session credentials and forge communication.

Adopting secure session management practices is essential:
- Implementing strong session IDs that are resistant to prediction and fixation.
- Regularly rotating session IDs after login or at predefined intervals.
- Using cookies with the ‘Secure’ and ‘HttpOnly’ attributes to protect against XSS attacks.
- Implementing server-side session validations to prevent session tampering.
Employee and User Education
Creating awareness about session hijacking among employees and users is crucial in preventing successful attacks. This includes:
- Teaching users to avoid clicking suspicious links or downloading suspicious files.
- Encouraging the use of strong, unique passwords and Brute Force Attack: A trial and error method used by applica....
- Emphasizing the importance of logging out after a session to invalidate session cookies.
- Providing regular training on recognizing and mitigating phishing attacks.
Session hijacking is a stealthy threat that can have severe consequences for both individuals and organizations. By understanding the mechanics of session hijacking and implementing effective preventive measures, users and organizations can significantly reduce their risk exposure and protect against this pervasive security threat.
