Real-Time (Reverse-Proxy) Login Phishing

An advanced phishing page relays your login to the real site in real time, capturing your password AND your session — defeating even two-factor codes.

Think a message like this reached you? You can check it right now.

What this scam is

You click a link to a page that looks exactly like a real login. As you type, the page secretly forwards everything to the genuine site and passes back what it shows — so when you enter your password and your two-factor code, the attacker captures the live session cookie and is logged in as you, even though you used MFA. The defense is not entering credentials on links, using phishing-resistant security keys/passkeys, and watching the web address closely.

What it usually looks like

  • A perfect-looking login page reached from a link.
  • It accepts your password and 2FA code normally.
  • The real service seems to work — but the attacker now has your session.
  • A web address that is subtly wrong.

Common warning signs

  • Logging in through a link rather than the app/bookmark.
  • A URL that's close but not exactly the real domain.
  • 2FA that 'works' but you didn't initiate the login.
  • Unexpected new-device alerts afterward.

Example wording scammers use

Security check required — sign in to confirm your account: [lookalike link].
(The page looks identical to your real login and even accepts your MFA code.)

These are illustrative examples written by ScamSplain, not real messages.

What the scammers want

  • Your live session cookie (bypassing MFA).
  • Your password and 2FA code as you enter them.
  • Immediate account access.

What to do

  • Never log in via links; use bookmarks or type the address yourself.
  • Use phishing-resistant security keys or passkeys where possible.
  • Scrutinize the exact web address before entering anything.
  • Report suspicious login pages.

What to do if you already responded

  • Change your password and, crucially, sign out all sessions/revoke tokens.
  • Re-enroll MFA and check for new devices/rules.
  • Report to IT and at reportfraud.ftc.gov.
