Hello! This is a test page that demonstrates a tabnabbing attack on your browser.
If the website which opened this page was configured correctly, nothing happened. Which means that the page you were visiting is still open in your browser. Go check it now!
The previous page was safe. This page could not change the tab/window!
But..if the website uses no protection, this “malicious” page tries to change the website!
Read about this vulnerability in my blog post here.
