The domain xn--80a6aa.xn--ktt-8cdy4di0oe90r.xn--flh-6cda3ad3eafboaeg4b8wgg001bt11reaf.app-s1.eu.com was registered on 21 February 2026 through Instra Corporation Pty Ltd. DNS resolution points to the IPv6 address 2606:4700:3030::6815:5acd, which belongs to AS13335 operated by Cloudflare, Inc. The authoritative nameservers are ns1‑ns4.centralnic.net, and the MX record is a wildcard null MX hosted by centralnic.net, indicating that the domain does not accept inbound mail. An HTTPS handshake is available; the presented SSL certificate received an E6 rating, suggesting a low‑quality or self‑signed certificate. HTTP requests return a 404 Not Found page title, confirming that no landing page is currently hosted. VirusTotal analysis shows that four of ninety‑three scanned security vendors flagged the domain, reflecting a modest detection rate.

The domain is listed on a single external blocklist and is actively blocked by the PhishDestroy service, reinforcing its classification as malicious. Gridinsoft’s trust scoring engine assigned a score of 0 out of 100, indicating an extreme lack of trust. The site is currently offline, which may be a takedown or a temporary removal.

Given the elevated risk rating, defenders should continue to block the domain at network perimeter and DNS layers, monitor for any resurrection of the site, and consider adding the IPv6 address to deny‑list rules. Threat‑intel teams should correlate any observed traffic to the Cloudflare IP range with this specific domain and watch for future registrations that reuse similar punycode patterns. Continuous re‑scanning with multi‑vendor services is recommended to capture any changes in detection status.
