coinpayu[.]app

Analysis indicates that the domain coinpayu.app was registered through NiceNIC International Group Co., Limited on 4 December 2025. The domain is hosted in Germany under ASN 214036 (Ultahost, Inc.) and resolves to IP address 84.200.154.171, which is associated with the same hosting provider. No TLS certificate is presented for the site, meaning connections would be unencrypted. The authoritative name servers are diana.ns.cloudflare.com and kai.ns.cloudflare.com, both Cloudflare‑managed, suggesting the operator leveraged Cloudflare’s DNS service to obscure the origin of the hosting.

The web server responded with the default Plesk Obsidian 18.0.55 title, a generic control panel identifier rather than any brand‑specific landing page, and the Gridinsoft trust score is 0 out of 100, indicating a highly untrusted reputation. The domain appears on two known phishing blocklists, PhishDestroy and ScamSniffer, and 6 of 95 security vendors on VirusTotal flagged the domain as malicious, reinforcing the suspicion of abuse. Current monitoring shows the site is taken offline, but the historical presence on blocklists and the low trust score suggest the domain was used for a phishing campaign.

Defenders should continue to block coinpayu.app at DNS and proxy layers, monitor for any re‑appearance of the domain or its IP address, and consider adding the IP 84.200.154.171 to firewall deny lists. Additional investigation of the hosting provider Ultahost, Inc. may reveal related infrastructure used in other campaigns. At present, the exact payload or credential‑harvesting mechanism remains unknown because the site content has not been captured.
