This site impersonates Microsoft with a French-language page titled "Vérifiez votre numéro de téléphone - Microsoft" ("Verify your phone number"). It is aimed at Microsoft and Office users. The hostname is built to look like an internal Office file-sharing address, and it opens with what reads like a person's name. PhishDestroy first flagged it on 2026-09-19. The site has been offline since 2026-09-20, and on 2026-10-19 its DNS was still inactive.
How the scam works
Lures like this usually arrive as a "shared document" link. A sender name in front of an Office-style domain makes the message feel personal and expected. Instead of a file, the visitor gets a Microsoft-branded prompt asking them to confirm their phone number. This kind of step is often paired with a request for the account password or the one-time code Microsoft then texts. Anyone who completes it can hand an attacker the login, the second factor, or both, and lose control of their mailbox, OneDrive files and anything else tied to the account.
Evidence
17 of 89 VirusTotal engines marked the site as malicious on 2026-09-20, the day after it was first flagged. The named vendors include BitDefender, Certego, CRDF, ESET, Emsisoft, Forcepoint ThreatSeeker, Fortinet and G-Data. urlscan.io independently returned a malicious verdict and recognised Microsoft branding on the page. That matches the brand named in the page title. The site is listed on the PhishDestroy blocklist.
Infrastructure
The domain office-share-microsoft.com was registered on 2026-07-15 through Cloudflare, Inc. That is about two months before PhishDestroy detected it, so the name was likely set aside early and used once the campaign was ready. The site was served from Cloudflare's network (172.67.179.214, geolocated to Canada), which hides the real origin server. Its certificate came from Google Trust Services (WE1), which gave the page a normal padlock and lent it false credibility.
What to do
If you entered a phone number, password or SMS code here, change your Microsoft account password from a device you trust. Review the security info and sign-in activity on your account and remove any phone numbers, authenticator apps or recovery addresses you do not recognise. Switch from SMS codes to an authenticator app or a passkey, and treat any unexpected Microsoft texts or calls as hostile. Admins should block office-share-microsoft.com and its subdomains, search mail logs for messages linking to it, and reset credentials and sessions for any users who clicked.

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.
