A novel phishing technique called browser-in-the-browser (BitB) attack can be exploited to simulate a browser window within the browser in order to spoof a legitimate domain, thereby making it possible to stage convincing phishing attacks.

According to penetration tester and security researcher, who goes by the handle mrd0x_, the method takes advantage of third-party single sign-on (SSO) options embedded on websites such as “Sign in with Google” (or Facebook, Apple, or Microsoft).

While the default behavior when a user attempts to sign in via these methods is to be greeted by a pop-up window to complete the authentication process, the BitB attack aims to replicate this entire process using a mix of HTML and CSS code to create an entirely fabricated browser window.
