Preventing Browser in the Browser Attacks

Hackers just found a way to show you a “perfect” Microsoft or Google login popup with the right logo and a convincing address bar, but the whole thing is fake. It is powered by a phishing kit called Sneaky2FA, which uses a browser‑in‑the‑browser (BitB) trick to steal both your password and your session, even if you use 2FA.

When you click “Sign in with Microsoft” or “Sign in with Google” on a malicious site, the page can draw a fake browser window inside the website using HTML and CSS. It shows what looks like a real URL bar, buttons, and resize behavior, while quietly talking to a backend that captures your login details and cookies as you sign in.
