Ethical Hacking Questions Medium
Session hijacking attacks refer to the unauthorized takeover of an ongoing session between a user and a system. There are several types of session hijacking attacks, including:
1. IP Spoofing: In this attack, the attacker spoofs or forges the IP address of the victim to gain unauthorized access to the session. By impersonating the victim's IP address, the attacker can intercept and manipulate the session.
2. Man-in-the-Middle (MitM) Attack: In a MitM attack, the attacker intercepts the communication between the user and the system. By positioning themselves between the two parties, the attacker can eavesdrop on the session, modify the data being transmitted, or even inject malicious code.
3. Session Sidejacking: Also known as session hijacking over unencrypted networks, this attack involves the interception of session cookies or tokens transmitted over insecure channels. By capturing these session identifiers, the attacker can impersonate the user and gain unauthorized access to the session.
4. Cross-Site Scripting (XSS): In an XSS attack, the attacker injects malicious scripts into a trusted website that the user visits. These scripts can then steal session cookies or perform actions on behalf of the user, leading to session hijacking.
5. Session Fixation: This attack occurs when an attacker forces a user to use a predetermined session identifier. By tricking the user into authenticating with a session identifier controlled by the attacker, they can hijack the session once the user logs in.
6. Session Replay: In this attack, the attacker captures and replays a legitimate session to gain unauthorized access. By intercepting and replaying the session data, the attacker can bypass authentication mechanisms and gain control over the session.
It is important for organizations to implement proper security measures, such as using secure protocols (e.g., HTTPS), regularly updating software, and employing strong session management techniques, to mitigate the risk of session hijacking attacks.
