BITB – Browser Templates For The Browser In The Browser Attack

The idea of a BITB (Browser Templates For The Browser In The Browser) attack came about because of new computer threats. This advanced method includes manipulating browsers within browsers and taking advantage of security holes to break security.

By looking into the details of this attack, we find a scary way that bad people can break into systems and possibly get access to private data without permission.

Understanding BITB is important if you want to strengthen your digital defenses and stay ahead of cyber threats in the ongoing fight against them. For more information..

Usage

Each folder has a file that has four variables that must be modified:

• XX-TITLE-XX: The title that shows up for the page (e.g. Sign in to your account now)
• XX-DOMAIN-NAME-XX: The Domain name you’re masquerading as. (e.g. gmail.com)
• XX-DOMAIN-PATH-XX: Domain path (e.g. /auth/google/login)
• XX-PHISHING-LINK-XX : Phishing link which will be embedded into the iFrame (e.g.)

Furthermore, if you’re using a Windows template, you should update the icon of the website you’re masquerading as. The default logo is Microsoft.

Windows-DarkMode-Delay

The Windows-DarkMode-Delay folder makes use of jQuery’s fadeIn() function to add a slight delay to the pop-up window as it appears.

This is only one way of making the Window appear in a delayed fashion; there are various other ways to do the same.

Demo

Detecting Color Preference

To get the most out of this, you should determine the OS from the user agent and the color preference and display the appropriate template.

Detecting BITB

Dragging the Window

One way of detecting BITB is by attempting to drag the window to the edge of the browser. If the window cannot escape the browser then it’s not a real window.

Browser Extension

@odacavo released a great browser extension that can detect and warn users about embedded iframes. It’s available here
