browser-in-the-browser (BitB) A phishing 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.
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).
the browser-in-the-browser "BitB" attack aims to replicate this entire process using a mix of HTML and CSS code to create an entirely fabricated browser window , by a pop-up window to complete the authentication process
the window design with an iframe pointing to the malicious server hosting the phishing page, and it's basically indistinguishable,JavaScript can be easily used to make the window appear on a link or button click, on the page loading etc."
the technique has been abused in the wild at least once before. In February 2020, a campaign that leveraged the BitB trick to siphon credentials for video game digital distribution service Steam by means of fake Counter-Strike: Global Offensive (CS: GO) websites.
While this method significantly makes it easier to mount effective social engineering campaigns, it's worth noting that potential victims need to be redirected to a phishing domain that can display such a fake authentication window for credential harvesting.
