demo.mosci.ai is a page that presents itself under AT&T branding, and PhishDestroy classifies it as impersonation phishing aimed at AT&T customers. PhishDestroy first detected it on 2026-09-25. As of 2026-10-19 the site was still online and redirecting visitors to other content. The page title reads "AT&T × MomentScience", which suggests a co-branded demo page, while our classification treats the use of AT&T's identity as impersonation.
How the scam works
Impersonation pages borrow a trusted brand's name and look so visitors lower their guard. A carrier brand like AT&T is effective bait because people expect messages about their account, billing or rewards. Pages of this kind typically lead visitors toward a form, an offer or a further redirect. The goal is to collect login details, personal information or payment data that the visitor believes they are giving to AT&T. Because this site redirects, the page a visitor finally reaches may not be the one the original link appeared to promise.
Evidence
On 2026-09-29, 10 of 91 VirusTotal engines flagged the domain. The flagging vendors include BitDefender, ESET, Fortinet, G-Data, Forcepoint ThreatSeeker, CRDF, Gridinsoft and SOCRadar. That is a minority of engines, but the detections come from several independent vendors. urlscan.io rated the page malicious and identified AT&T as the brand on display. Among blocklists, it is currently listed by PhishDestroy.
Infrastructure
The parent domain mosci.ai was registered through Namecheap on 2025-02-21. That is roughly nineteen months before this subdomain came to our attention, so this is not a freshly registered throwaway domain. Traffic is served through Cloudflare's network on an address geolocated to Canada. This means the origin server sits behind Cloudflare's proxy and is not directly visible.
What to do
If you entered your AT&T login on this page, change that password immediately and turn on two-step verification for your account. Also add an account PIN or passcode with AT&T to make SIM-swap and port-out attempts harder. If you entered card details, ask your bank to block the card and watch your statements for unfamiliar charges. Treat any follow-up calls or texts that cite what you submitted as part of the same scheme. Security teams should block demo.mosci.ai, search proxy and email logs for visits or links to it, and warn users who reached it.

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.
