What is clickjacking?
Clickjacking is a trick where a malicious website tricks you into clicking on something different than what you think you’re clicking on. Imagine you’re trying to click on a button, to play a video, but instead, you’re actually clicking on a hidden link that does something else, like sharing your personal information, downloading malware, transferring funds, or liking a page without you knowing. It’s like a digital bait-and-switch.
