Importance of Clickjack Attack
The term “Clickjack Attack” is important in the realm of technology as it refers to a malicious online technique employed by hackers that deceives users into unknowingly clicking on concealed or disguised website elements, such as buttons or links, which ultimately leads to unintended actions.
These actions vary from sharing personal information, downloading malware, or changing privacy settings to the advantage of the attacker.
By understanding and being aware of Clickjack Attacks, users and organizations can take proper precautions and implement security measures to safeguard their digital assets and prevent potential online threats, highlighting the significance of the term in maintaining internet safety and promoting robust cybersecurity practices.
Clickjack attacks serve as a malicious technique used by cybercriminals to manipulate users into unwittingly performing actions on websites without their consent or knowledge. The primary purpose of this tactic is to exploit the trust and familiarity users have with certain websites, tricking them into revealing confidential information, clicking on advertisements, or even liking and sharing content on social media platforms.
This is usually achieved by overlaying invisible elements or crafting disguised buttons over legitimate website content, leveraging the user’s actions to generate profit for the attacker, or to otherwise compromise their security and privacy. In terms of application, clickjack attacks can have considerable consequences for both users and organizations.
For instance, cybercriminals may target e-commerce platforms to fraudulently obtain financial details or social engineering schemes to gather personal information. Apart from its financial implications for users, clickjacking can also lead to the tarnishing of a user’s online reputation, if they unintentionally share explicit content or misleading information on their social media profiles.
Furthermore, clickjacking can compromise the security of businesses, as attackers can trick users into granting them admin access, downloading malware, or infringing upon valuable intellectual property. Vigilance, adequate safeguard measures, and user-awareness education are therefore essential to counteract this form of cyber manipulation.
Examples of Clickjack Attack
Facebook “Like” Button Clickjacking: In 2010, a popular clickjacking attack targeted Facebook users through malicious websites that encouraged them to click on disguised “Like” buttons. Unbeknownst to the user, these buttons were hidden under seemingly harmless elements like quizzes, games or other clickable content. Once clicked, it would share the malicious link, unknowingly spread by the user to their friends through Facebook’s news feed and increase the risk of exposing their friends to the clickjacking attack as well.
Twitter Share Button Clickjacking: In 2012, a clickjacking attack on Twitter involved a disguised “Share” button on various third-party websites. Users who clicked this button were unknowingly retweeting a link to a malicious site, which could lead to downloading malware or gaining unauthorized access to personal information. This attack not only compromised users’ security but also spread the infected URL, potentially affecting other users on Twitter.
Google’s DoubleClick Ad Network: In 2014, the DoubleClick ad network, a Google subsidiary, was targeted by clickjacking attackers. Cybercriminals used hidden iframes and other techniques to trick users into clicking invisible ads on popular websites, artificially inflating ad views and clicks. This allowed the attackers to gain revenue through ad fraud and even redirect users to malicious websites, placing users at risk of downloading malware or having their personal data stolen.
