  • Individual users – Anyone who uses websites or apps for sensitive tasks like banking, shopping, or managing personal data.
  • Organizations – Organizations managing websites or apps to understand this new threat and protect their users.

What is double clickjacking?

Double clickjacking is a tricky cyberattack that manipulates how users interact with websites or apps. It targets something most of us do without thinking—double-clicking.
Here’s a simple example:
Imagine you’re trying to turn on a light with a double-click, but after the first click, the switch suddenly changes and now controls your garage door instead.
This is how double clickjacking works. Hackers change what your second click does without you knowing. been fixed, they serve as a reminder to always be cautious when using third-party plugins.

How does it work?

The setup – You visit a website that looks safe and normal. It might ask you to double-click something, like a CAPTCHA or a confirmation button.
The switch – Between your first and second clicks, the website’s code quickly changes what your second click will do. For example:

  • Instead of confirming your action, you might approve a payment to a hacker.

The consequence – You have no idea this switch happened. Hackers have now tricked you into doing something you never intended.ng third-party plugins.

Why did it happen?

  1. It exploits a habit – Double-clicking feels natural, so it’s hard to suspect anything is wrong.

  4. Minimal effort required – Hackers don’t need fancy phishing emails or malware; they just wait for you to double-click.

  3. Keep software updated: Update your browser and apps regularly to receive security patches.

For organizations

  1. Add confirmation steps: For critical actions, require additional manual confirmation (e.g., re-entering a password).
  2. Monitor unusual activity: Set up alerts to detect suspicious user interactions.
  3. Conduct security testing: Perform regular tests to identify vulnerabilities in user interaction workflows.
  4. Collaborate with security experts: Partner with researchers to stay ahead of emerging threats like Double-Clickjacking.
