I'm sure you've heard the term. Do you know what it means? Clickjacking is a malicious technique that uses vulnerabilities in your web browser to trick web users into revealing confidential information or give s the attacker control of their computer while clicking on seemingly innocuous Web pages.
It is a serious problem that diligent patching of your system and software will only partially protect. Malicious hackers still know of undiscovered holes in our systems even when we are fully patched & updated. I apologize if I seem to be a scaremonger but the only way to be sure you're protected is to stay meticulous about knowing where your visiting online and what you're clicking on.
