Browser templates for Browser In The Browser (BITB) attack.

More information: https://mrd0x.com/browser-in-the-browser-phishing-attack/

Each folder has a index.html file which has 4 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 - 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. https://example.com)

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

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's various other ways to do the same.

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.

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.

@odacavo released a great browser extension that can detect and warn users about embedded iframes. It's available here: https://github.com/odacavo/enhanced-iframe-protection
