TCP session hijacking occurs when a hacker takes over what?

• A. The DNS Server
• B. A User Account
• C. The TCP Session Between Two Machines
• D. An Email Account

Answer: (C)

The concept being tested is the ability to take control of an active communication channel between two hosts. TCP session hijacking happens when an attacker inserts themselves into an already established TCP connection, effectively pretending to be one of the endpoints. By gaining access to the live session, the attacker can intercept, inject, or modify the data being exchanged, or even terminate the connection. This relies on exploiting trust in the ongoing TCP session, often in environments where the channel isn’t protected by strong encryption or authentication. The other options aren’t about hijacking a TCP connection. Taking over a DNS server relates to DNS hijacking or poisoning, which targets name resolution rather than an existing TCP session. Taking over a user account or an email account involves credential compromise or account takeover, not the ongoing TCP session between two machines.
