What is Clickjacking, its Type and How to prevent it?
Clickjacking, one must be thinking, what does it mean, and what is the primary goal of its attack? Fortunately, you have come to the right place. In this article, we are going to talk about clickjacking attacks and clickjacking prevention techniques.
What is clickjacking?
Clickjacking is a type of cyber attack in which users are tricked into believing something that they are seeing is real, but in reality, it is not. For instance, the attacker may create a duplicate interface just like the original interface or even make a fake HTML element and then run it inside an iframe over the original page.
This creates a perfect environment for a clickjacking attack to cheat the user and take advantage of the user’s vulnerability. Its attack is also known as a UI redress attack or user interface redressing.
That being said, let us discuss some of the techniques of it.
Types of clickjacking:
1. Cropping: This occurs when the attacker changes the layout of the legitimate page as per their liking. For instance, they can change the controls of the page by adding a redirect link for the user that takes them to the attacker’s desired location or simply changing the content or the layout of the website to confuse the user.
2. Click event dropping: As the name suggests, in this approach, the user will feel that the website is not responding after they have clicked on the desired section, but in reality, the clicks are been accepted and running their programmed steps on the malicious page.
3. Transparent overlay: This method is one of the most common clickjacking techniques to trick the user. In this technique, the attacker makes an overlay of a completely legitimate webpage or a web application over their malicious page. Due to this, the user is not able to differentiate between the legitimate page and the fake page.
4. Hidden overlay: The attacker creates a small 1×1 pixel iframe to position it under the mouse cursor. As soon as the user clicks anywhere on the page, the command will go directly to the malicious page that the attacker has set up.
5. Scrolling: In this approach, the attackers create a legitimate pop-up or dialog box. Once the user clicks on the particular pop-up button, it directly activates the malicious webpage, which was portrayed as a harmless prompt to the user.
One drawback of this is that the user might be using an ad blocker that might block the whole attack.
How to prevent clickjacking:
There are some techniques that can be used in clickjacking attack prevention, and they are as follows:
1. Preventing clickjacking using JavaScript:
You might be thinking about how to prevent it in React JavaScript. Well, the answer to that is quite easy: server-side protection and a JavaScript frame-busting technique are one of the most commonly used methods to fight against this cyber threat.
2. Clickjacking protection using frame ancestors:
When it comes to preventing vulnerabilities, it is one of those tools that can be used without a doubt.
Some of the frequently asked questions and answers:
1. How can clickjacking attacks be mitigated?
Ans: Mitigation for clickjacking can be done by following the steps. The X-Frame-Options header can be used for the server side while implementing the frame-ancestors directive on the content security policy in order to control the embedding of the website on other sites.
2. What is a clickjacking attack?
Ans: Clickjacking is when an attacker tricks users into clicking on something that they are not supposed to do or intend to do in order to extort the user’s confidential pieces of information, transfer money, or download malware on their device for various reasons.
3. What is clickjacking in cyber security?
Ans: Clickjacking is a type of malicious attack done on the user by the attacker to get hold of confidential information, download malware, or authorize an unauthorized purchase.
4. What is a clickjacking vulnerability?
Ans: Attackers can trick the user into clicking on certain links that they need the user to click in order to give them access to the attackers to perform various tasks, such as transferring money, confidential pieces of information, passwords, or downloading malware on the user’s device for further processes. Thus, it is safe to say there are many vulnerabilities to clickjacking.
5. What does clickjacking mean?
Ans: In layman’s terms, Clickjacking is a type of attack technique that is used by the attacker to trick the user into believing that they are clicking on the intended place, but in reality, they might be clicking on something that the attacker has planted for their user to click on. One of the most common examples of clickjacking is a pop-up window on a website; as such, they are most of the time laced with some kind of fishy content.
6. Is clickjacking a serious vulnerability?
Ans: Is clickjacking a vulnerability? The answer to this question is YES! Clickjacking can be termed as a great vulnerability; as such, it can be used to trick the user into clicking on some specified spots or links in order to take advantage of the vulnerability of user.
7. Clickjacking: How to prevent?
Ans: Clickjacking can be prevented through frame busting on the client side and X-Frame options on the server side.
8. Which of the following is an example of a clickjacking attack?
Ans: There are many click-jacking attack instances, such as Facebook page liking, unauthorized purchases, malware downloading into the user’s device, or simply stealing the credentials of user.
9. What is the solution to clickjacking?
Ans: The basic solution to clickjacking for the user is to be intuitive and always look where you are clicking; as such, there are many clickbait links that the attacker might have planted for the user to click. Apart from this, there are a few other options that websites are required to take to prevent clickjacking.
10. What is the other name for clickjacking?
Ans: Clickjacking is also called a user interface redress attack or user interface redressing.
11. What is the root cause of clickjacking?
Ans: Clickjacking is a form of deception; as such, it is performed by deceiving the user into believing something that is not true. For instance, the attacker can create a transparent layout of the interface and then mask it on the original interface to trick the user into thinking something that they think is not there.
12. How do you test for clickjacking?
Ans: The click-jacking test can be done by creating an alternative HTML page and then attempting to put a sensitive page in an iframe from the website; as such, this is typical click-jacking behavior. Thus, one must always run the clickjacking checker test code on a different web server.
13. What is an anti-clickjacking header?
Ans: To protect against clickjacking attacks on websites, an anti-clickjacking security mechanism is used. If any website or application reports about an anti-click-jacking header vulnerability, then it is safe to say that particular site is not sending the required HTTP response header in order to defend against a click-jacking attack.
Conclusion:
In a nutshell, it is safe to say that web applications are potentially vulnerable to it. Mentioned above is all the information regarding it that you must know. The world of the internet is going on and on, and there are new innovations on a daily basis, so you cannot deny the fact that the internet will soon eliminate manpower in many fields.
