Clickjacking, also known as UI redress attack, is a type of malicious activity that tricks a user into clicking on a button or link on a page other than the one they intended to. By doing so, the attacker can perform an action on the page that the victim is not aware of, such as liking a page, downloading a file, or clicking on an advertisement.
In some cases, the attacker can even hijack the victim's entire account by getting them to click on a "connect" or "login" button that actually takes them to the attacker's own page. Once the victim's credentials have been entered on the attacker's page, the attacker can then use those credentials to gain access to the victim's account.
Clickjacking can be used to carry out a wide variety of attacks, depending on what the attacker's goals are. For example, an attacker could use clickjacking to increase the number of likes on their own Facebook page by getting victims to unwittingly like the page while they are browsing other sites. Or, an attacker could use clickjacking to spread malicious software by getting victims to click on a link that downloads the software onto their computer.
Clickjacking is a serious security threat because it can be used to carry out attacks that are difficult to detect and defend against. For example, an attacker could use clickjacking to hijack a victim's Facebook account and then post malicious content on the victim's behalf, which could lead to the victim's friends and followers being exposed to the attack as well.
Clickjacking attacks exploit the fact that web browsers allow users to click on links and buttons that are embedded in other pages. For example, if you are browsing a website and you see a button that says "like" or "share", you can click on that button to like or share the page that you are currently viewing.
However, what you may not realize is that it is possible for an attacker to embed that button in another page without your knowledge. So, when you click on the button, you are actually liking or sharing the attacker's page, not the page that you thought you were.
This type of attack is possible because of the way that web browsers work. When you visit a website, the browser loads the HTML code for that website and then renders the page on your screen. The HTML code includes instructions for the browser on how to display the page, including the location of any buttons or links that are on the page.
However, the browser does not check to see if the HTML code is coming from the same website that you are currently viewing. This means that an attacker can send you a page that includes HTML code that is embedded from another website. When you click on a button or link on the page, you are actually interacting with the other website, not the website that you thought you were.
There are a few things that you can do to protect yourself from clickjacking attacks. First, you should be aware of the fact that these attacks exist and that they can be used to trick you into clicking on things that you didn't intend to.
If you are ever unsure about a button or link on a webpage, you can hover your mouse over it to see where it is actually going to take you. If the address that is displayed is not the same as the website that you are currently viewing, then you should not click on it.
In addition, you can install a browser plugin that will block clickjacking attacks. These plugins work by detecting when a button or link is embedded in a page from another website and then preventing you from clicking on it.
One popular plugin that you can use is the NoScript plugin for Firefox. This plugin is available for free from the Mozilla website.
Clickjacking attacks are a serious security threat and you should take steps to protect yourself from them. By being aware of the risks and taking steps to protect yourself, you can help to keep yourself safe from these attacks.
