Which type of communication is typically disrupted by session hijacking?

Session hijacking primarily disrupts the communication mechanisms established during a session, particularly focusing on how a user interacts with web applications and services. In this context, the effective answer relates to web browsing, as this is the most common scenario in which session hijacking occurs.

When an attacker successfully hijacks a session, they exploit the interaction between a user's browser and a web server. This attack typically involves intercepting or manipulating session tokens or cookies, allowing the attacker to impersonate the user without needing their credentials. Due to the nature of web applications, the disruption most evident is in the usability and security of web browsing sessions, making it the primary target for such attacks.

While data transmission is a broader term that encompasses all forms of data exchange, session hijacking specifically targets sessions created for web browsing, which is why web browsing is the ideal focus point in answering the question regarding session hijacking scenarios.
