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: https://github.com/odacavo/enhanced-iframe-protection
