Enhanced iFrame Protection (EIP) is a lightweight extension to automatically detect and provide verbose warnings for embedded iframe elements in order to protect against Browser-In-The-Browser (BITB) attacks.
In the above screenshot, a phishing website has embedded an iframe element within a div that has been styled to look like an actual browser window (with a fake URL bar claiming to be from accounts.google.com).
This extension has detected the iframe and presented a security warning, highlighting the actual phishing domain as (bigphish.ca).
