x-mtp[.]online

Analysis of x-mtp.online indicates a brand impersonation campaign targeting the Arbitrum ecosystem. The domain was registered on October 21, 2025 through IONOS SE and resolves to the Amazon-owned IP address 75.2.60.5 (AS16509, United States). No SSL certificate is present, and the site returns no HTTP status information because the service has been taken offline. The page title retrieved during earlier scans was "XMTP Browser Developer Tools," a name that does not correspond to official Arbitrum resources and aligns with the reported wallet/seed phishing kit.

Infrastructure evidence shows the domain is served from Amazon’s cloud infrastructure, a common choice for rapid deployment of malicious sites. Nameserver delegation points to four ui-dns servers (ns1070.ui-dns.biz, ns1093.ui-dns.com, ns1100.ui-dns.de, ns1113.ui-dns.org), a pattern observed in other recent phishing deployments. The domain appears on two security blocklists and is actively blocked by PhishDestroy and ScamSniffer, confirming that threat‑intel communities have identified it as malicious. VirusTotal reports that the domain was scanned by 95 vendors, with no detections reported at the time of analysis; this absence of detections does not imply safety.

Gridinsoft assigns a trust score of 0 out of 100, further indicating high risk. The current offline status limits real‑time observation, leaving the exact page content and any credential‑harvesting mechanisms unverified. Defenders should continue to block the domain at DNS and proxy layers, monitor for new sub‑domains under the same registration and hosting patterns, and treat any communications referencing XMTP or Arbitrum from this host as fraudulent. Ongoing vigilance is recommended to catch any re‑activation attempts or related infrastructure reused in future campaigns.
