System Hacking: Journey into the Intricate World of Cyber Intrusion  
                     The Ghost in the 
Machine: Unmasking the 
Art of Session Hijacking
Imagine walking through a busy marketplace with your digital wallet 
open. Now picture a shadowy figure slipping their hand into your pocket 
to steal not cash, but the key to your identity and transactions. This is 
session hijacking, a chilling tactic used by attackers to impersonate users 
without needing their credentials.
In the Certified Ethical Hacker (CEH) course, session hijacking is a critical 
vulnerability that demands practical understanding. Attackers become 
the ghost in the machine, inheriting all privileges of their victims by 
exploiting session tokens.
How Session Hijacking

When you log into a website, the server issues a unique Attackers steal this token to impersonate you, bypassing

you to navigate without repeatedly entering credentials. privileges.
Techniques Used in 
Session Hijacking
Session Sniffing
Attackers intercept unencrypted communication to capture session 
tokens, highlighting the need for HTTPS.
Cross-Site Scripting (XSS)
Malicious scripts injected into websites steal session cookies and send 
them to attackers.
Man-in-the-Middle (MITM)
Attackers intercept communication between user and server, 
capturing session tokens.
Session Fixation
Users are tricked into using a session ID known by the attacker, 
allowing hijacking if the session ID isn't regenerated.
