Clickjacking, also known as user-interface or UI redressing attacks, is a type of cyber-attack that tricks users into clicking on a button or link that is hidden from view or appears to be something else. In this blog, we will discuss what clickjacking is, how it works, and what you can do to prevent it.
What is Clickjacking?
Clickjacking is a technique used by cybercriminals to deceive users into clicking on a link or button that performs an unintended action. The attacker uses various methods to hide the true nature of the button or link, making the user think they are clicking on something else entirely. This can lead to the user unknowingly performing an action they did not intend, such as downloading malware or making a payment.
How Does Clickjacking Work?
Clickjacking attacks work by overlaying a transparent layer over a legitimate webpage, making the user think they are clicking on a real button or link, when in fact, they are clicking on the transparent layer. This transparent layer can be created using HTML or CSS, and can be designed to look like a button or link, or it can be completely invisible.
The attacker can then place the hidden button or link over a legitimate button or link, causing the user to accidentally click on the hidden element instead of the real one. This can result in actions such as downloading malicious software, visiting a phishing website, or making an unintended payment.
Preventing Clickjacking Attacks
Use X-Frame-Options: Implementing the X-Frame-Options HTTP response header can help prevent clickjacking attacks by blocking the loading of the webpage within a frame or iframe.
Implement Frame Busting Code: Frame busting code is designed to prevent a webpage from being displayed within a frame or iframe, making it more difficult for attackers to carry out clickjacking attacks.
Use Content Security Policy (CSP): CSP is a security mechanism that allows web administrators to define the types of content that can be loaded on a webpage. This can help prevent clickjacking by blocking the loading of external content.
Educate Users: Educating users on the dangers of clickjacking and how to recognize suspicious activity can help prevent attacks from being successful.
Keep Software Up to Date: Keeping web browsers and operating systems up to date can help prevent clickjacking attacks by patching vulnerabilities that can be exploited by attackers.
In conclusion, clickjacking is a serious threat to online security that can result in the loss of sensitive information, financial loss, or the installation of malicious software. By implementing X-Frame-Options, frame busting code, and content security policy, educating users, and keeping software up-to-date, you can help prevent clickjacking attacks and protect your online identity and assets.
