The Secret To Cookie Hijacking Is Revealed
In the digital age, everyday computer session is a temporary interaction you have with a website. That means, the time between you first log into your account and then log off after your operation is a session. In this hijacking, a malicious hacker seats in between your system and the website’s server, while you are connected in an active session. In other words, cookie hijacking is another form of man-in-the-middle attack that will give a hacker access to your account. In this session, we are going to acquire certain useful information regarding cookie hijacking and how to prevent hijacking sessions in the upcoming segment, which will help you a lot in many ways.
Things to know about cookie hijacking
First, you have to understand what session hijacking before going to address the issues is. A session is the time-frame in which the authentication of a user on a site is valid. Mostly, sessions are created because requesting user credentials at each access will be unproductive. Sessions are implemented via cookies, and these are to be submitted whenever a user-specific content is required by the browser. Presently used method is to give an identifier string to a user, and this identifier is called a session token.
The session token of a user is used to gain unauthorized access to their account, which is referred to as cookie session hijacking. It can lead to loss of sensitive data. That’s why understanding the general methods used by hackers to hijack session is crucial for end-users as well as developers. There are many ways that an attacker can stage a session hijacking attack. Below are some of the methods used to perpetrate a session hijacking attack:
1) Session side jacking
2) Session fixation
4) Cross-site scripting
Protection against session cookie hijacking puts on the hands of app developers who will have to make sure their programming practices are secure.
Be aware of session hijacking attack
It consists of exploiting the web session control mechanism, which is usually managed for a session token. HTTP communication uses various TCP connections, and the web server needs a technique to recognize every user’s connections. The effective method is based on a token that the web server sends to the client browser after successful client authentication. The session hijacking attack concessions the session token by stealing a valid session token to gain unauthorized access to the web server. Here, some of the ways that session token could be compromised that are mentioned below for your consideration:
– Client-side attacks
– Predictable session token
– Session Sniffing
– Man-in-the-browser attack
Example – Session sniffing
First, the attacker uses a sniffer to get a valid token session called a session ID, and then they use the valid token session to achieve unauthorized access to the webserver.
Example – Cross-site script attack
In this, the attacker can compromise the session token using the malicious code running at the client-side. It shows how the attacker could use an XSS attack to steal the session token.
Prevent the session hijacking today!
At a base level, session hijacking is made by limitations in the TCP/IP protocol, which is the technology responsible for permitting computers to communicate with servers. The method used to steal session-id is installing malicious code on the client website, and then the cookie is stealing. The only way to prevent session hijacking is to enable the protection from the client-side. Take preventive measures from both the client and server sides in order to prevent the session hijacking attack.
