office365mail.com is an impersonation phishing site that presented itself as Microsoft OneDrive, with a domain name chosen to look like a legitimate Office 365 mail service. It targets people who use Microsoft 365 for work email and file sharing, and who are used to getting 'a document has been shared with you' notices. PhishDestroy first flagged it on 2026-09-17. The site has been dead since 2026-09-29, and as of 2026-10-19 its domain no longer resolves.
How the scam works
Lures of this type usually arrive as an email claiming a file is waiting on OneDrive. The link opens a page titled 'OneDrive' that asks the victim to sign in with their Microsoft account before the document can be viewed. Anything typed there, usually the work email address and password and sometimes a one-time code, goes straight to the operators. With that access, attackers can read the mailbox, take over shared files and send new phishing or invoice-fraud emails from a trusted internal account.
Evidence
On 2026-09-25, VirusTotal showed 18 of 91 security engines flagging the domain. The vendors included Google Safe Browsing, Kaspersky, Fortinet, Forcepoint ThreatSeeker, Emsisoft, Gridinsoft, CRDF and alphaMountain.ai. Google Safe Browsing separately classifies it as SOCIAL_ENGINEERING, its category for deceptive pages that trick users into handing over credentials. The site is also listed on the PhishDestroy blocklist.
Infrastructure
The domain was registered through Name.com, Inc. on 2026-09-10, just seven days before PhishDestroy caught it. That short lead time is typical of throwaway phishing domains set up for a single campaign. Traffic ran through Cloudflare's network, with the address geolocated to Canada, so the real origin server was not exposed. The site used a free certificate from Google Trust Services, which means the padlock in the browser said nothing about whether the page was legitimate.
What to do
If you entered a Microsoft password on this site, change it immediately from the official Microsoft account page. Sign out of all sessions and check that your two-factor methods and recovery details have not been changed. Look for new mailbox forwarding rules, unfamiliar app consents and sent messages you did not write, and warn your IT team, since your account may have been used to phish colleagues. Defenders should block the domain at the mail gateway and proxy, search mail logs for messages linking to it, and reset credentials for any user who clicked through between 2026-09-17 and 2026-09-29.

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.
