What Is Hijacking Attack | How To How To Deal With Hijacking

When it comes to answering what is hijacking in computer, one must say hijacking is a type of network attack in which the attacker takes over the control and communication between the victim system and the network.
Any kind of information theft including password, email information, bank account information, etc. can be called a hijacking attack. These types of attacks can take many forms.

Types of Hijacking Attack

• Session Hijacking Attack
• DLL Hijackin Attack
• Fake Page Attack
• Putty Hijacking Attack
• Cross-Site URL Hijacking Attack
• SSH Session Hijacking Attack
• Browser Hijacking Attack
• MITM Hijacking Attack

Session Hijacking uses authentic computer sessions to access system information and services. In particular, this type of attack provides the attacker with authentication information through stealing cookies. A system acts as an intermediary between the web server and the user, and by storing cookies, they store information and exploit it.

The most popular method in Session Hijacking is source-routed IP packets. For instance, in this method, the attacker passes all the information traffic between two BC computers through his machine. Therefore, he can easily listen to all the information. Alternatively, when there is no access to routing, an attacker could use Blind Hijacking. In the Blind method, the attacker guesses the answers coming from the server and sends a command, but does not see a response and can only set a command. Setting a password to access the network from another location could be an example of such commands.

DLL hijacking attack uses Windows features to find the DLL path for destruction. If you know the DLLs used in an application, you can replace it with another file on the host and monitor your attacks. Addresses used in Windows:

a) current working directory of the application, highest priority, first check
b) windows
c) windowssystem32
d) windowssyswow64 —> lowest priority, last check
