microsoft-office365.site poses as a Microsoft Office 365 login portal. Its page title, "Iniciar sesion" (Spanish for "Sign in"), points to Spanish-speaking Microsoft users. PhishDestroy first flagged the domain on 2026-09-27, one day after it was registered. As of 2026-10-19 the site was still online and its content now redirects elsewhere, so the domain remains a live threat.
How the scam works
The domain name combines "microsoft" and "office365" to look like an official address in a link, email or search result. The visitor lands on a sign-in screen styled after Microsoft and is asked for an email address and password, and sometimes a one-time code. Whatever is typed goes to the operators. With those credentials they can take over the mailbox, read and send mail as the victim, reach files stored in the account, and reset passwords on other services tied to that email, including exchange and wallet accounts.
Evidence
Several sources confirm the site independently. On VirusTotal, 15 of 91 engines flagged it on 2026-09-30, among them BitDefender, ESET, Fortinet, Forcepoint ThreatSeeker, Emsisoft, CRDF, alphaMountain.ai and Criminal IP. Google Safe Browsing lists it as social engineering, and urlscan.io rated it malicious and detected the Microsoft brand on the page. Beyond PhishDestroy, the domain is on the MetaMask and SEAL blocklists, and it appears in three AlienVault OTX threat pulses.
Infrastructure
The domain was registered on 2026-09-26 and flagged within a day. That pattern fits a throwaway domain set up for a short campaign. Registration is through Cloudflare, Inc., and the site sits behind Cloudflare's network with a Canadian location, which hides the origin server. It holds a valid certificate from Google Trust Services, so the browser padlock appears as normal and does not mean the page is genuine.
What to do
If you entered your Microsoft credentials here, change that password right away from the official Microsoft site, and change it on any other service where you reused it. Turn on or reset multi-factor authentication. Review recent sign-in activity, mailbox forwarding rules and connected apps, and sign out all other sessions. If you also used this email for crypto exchanges or wallet services, secure those accounts and their recovery settings. Defenders should block the domain at DNS and the mail gateway, search logs for visits or submitted credentials, and force password resets for any affected users.

Registrar accreditation and DNS abuse obligations
For this gTLD, the registrar above operates under an ICANN accreditation agreement. The links below provide the official fee schedule and current DNS abuse compliance guidance.
Accreditation is a contract, not a safety certification.
RAA §3.18 establishes abuse-contact and handling requirements. This report can document stored outbound notices and later technical observations; it does not by itself establish receipt, investigation, remediation, or contractual non-compliance.
Saved certificate metadata. Certificate dates without a timezone are shown as stored. Transport encryption does not establish that the site is trustworthy.

Availability, content, DNS and registration are independent evidence layers. NXDOMAIN, an unreachable origin or missing content alone does not prove registrar action. A registrar or provider is credited only when a direct technical marker identifies that actor. Report causality is shown separately.

Hostnames retained in the domain record or Certificate Transparency cache. A hostname alone does not establish current availability or malicious activity.
