Session Hijacking Attack Complete Tutorial | Session ID and Cookie Stealing | Side Jacking Sniffing into Active Session: The attacker then finds an active session between the target and another machine and places himself between them. Using a sniffer like Wireshark, he captures the traffic and tries to gather information about the session. 2. Monitor: He then monitors the traffic for vulnerable protocols like HTTP, telnet, rlogin, etc., and tries to find any valid authentication packets passing through. 3. Session Id Retrieval: The attacker tries to predict the session id using available information. Now that a target has been chosen, the next step in the session hijacking process is sequence number prediction. Sequence number prediction is a critical step because failing to predict the correct sequence number will result in the server sending reset packets and terminating the connection attempt. If the attacker guesses the sequence numbers wrong repeatedly, the likelihood of detecting the attack increases. 4. Stealing: In application-level hijacking, active attacks are pursued to steal the session Id. Man in the middle attack, cross-site scripting, sniffing are used to steal the session id. Brute Forcing: This is a time-consuming process. While sequencing number guessing can be done manually by skilled attackers, software tools are available to automate the process. 5. Take One of the Parties Offline: Once a session is chosen and sequence numbers predicted, one of the targets has to be silenced. This is generally done with a denial of service attack. The attacker must ensure that the client computer remains offline for the duration of the attack, or the client computer will begin transmitting data on the network causing the workstation and the server to repeatedly attempt to synchronize their connections; resulting in a condition known as an ACK storm. 6. Take over the Session and Maintain the Connection: The final phase of the session hijack attack entails taking over the communication session between the workstation and server. The attacker will spoof their client IP address, to avoid detection, and include a sequence number that was predicted earlier. If the server accepts this information, the attacker has successfully attacked the communication session. Disclaimer: This video is made available for educational and informational purposes only.
