Fake Microsoft account code page that relays the victim's one-time code to the operator's server

family: ms-account-otp-relay-2026-11

A phishing page styled as a Microsoft account sign-in step titled 'Enter your code', with six boxes for a six-digit code. The link in the lure e-mail carries the target's e-mail address, and the page shows it as the account being signed in. The page sends that address to its own server, which starts a real sign-in to the victim's Microsoft account, so the victim receives a genuine one-time code from Microsoft. When the victim types the code into the fake page, it is relayed to the operator's server, which completes the sign-in and keeps the account's session; the page then forwards the victim to the real Microsoft sign-in site. The whole page is one self-contained HTML file with no external scripts, on a domain registered shortly before the e-mails go out. Seen in November 2026 at msftportallogin[.]com, reached through a mailing service's click-tracking link.

Matches the page's own code wherever it is served, whatever the domain: the two requests it makes to its own server (one to start the sign-in, one to pass on the code) and the sign-in states it reacts to (code sent, code rejected, password required, signed in, rate limited). No brand text is used, so the real Microsoft pages cannot match. The search adds the known domain and the page's title. A code typed into such a page lets the operator sign in to the account; change the password and review the account's recent sign-in activity if a code was entered.
