Q-1 | Computer Science homework help

q-1 UnknownpSession hijacking is a type of cyber attack where an attacker takes control of a user session after successfully obtaining or guessing their session identifier. In web contexts, this identifier is often a session token or a cookie that grants access to a user's account or session on a website or web application.

There are various methods attackers might use to hijack sessions:

• Packet Sniffing: Attackers can use packet sniffing tools to intercept and read network traffic between a user and a server. If the session identifier is transmitted in plaintext (without encryption), the attacker can capture it and use it to impersonate the user.
• Cross-Site Scripting (XSS): XSS vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users. If an attacker can inject a script that steals session cookies, they can hijack sessions of other users who visit the compromised page.
• Session Fixation: In this method, attackers force a user's browser to use a specific session identifier chosen by the attacker. The attacker then waits for the user to authenticate, either by logging in or by visiting a malicious link containing the predetermined session identifier.
• Man-in-the-Middle (MitM) Attacks: In a MitM attack, the attacker intercepts communication between two parties, allowing them to eavesdrop on and modify the traffic. This can include capturing session identifiers and using them to hijack sessions.

Once an attacker successfully hijacks a session, they can perform various malicious actions, such as accessing the user's account, stealing sensitive information, manipulating data, or impersonating the user. To mitigate session hijacking, websites and web applications often implement secure session management practices, such as using HTTPS to encrypt communications, employing secure cookies with the 'HttpOnly' and 'Secure' flags, regularly rotating session identifiers, and implementing mechanisms to detect and prevent suspicious activity.
