aavrcs[.]eu[.]com

The domain aavrcs.eu.com was registered on February 21, 2026 through Instra Corporation Pty Ltd. and is currently listed as offline. DNS resolution points to the IP address 104.21.16.1, which belongs to AS13335 Cloudflare, Inc. in the United States. The authoritative name servers are ns1.centralnic.net, ns2.centralnic.net, ns3.centralnic.net, and ns4.centralnic.net, and the MX record is configured to eu-com-wildcard-null-mx.centralnic.net with priority zero, indicating a placeholder mail setup rather than active email handling. An HTTPS handshake presents a Cloudflare TLS Issuing ECC CA 1 certificate, confirming the use of Cloudflare’s edge TLS service.

The HTTP response delivers a default "Welcome to nginx!" page title, suggesting that no custom landing page has been deployed or that the service was deliberately left generic. VirusTotal analysis shows that three of ninety‑three scanning engines flagged the domain, and the domain appears on a single security blocklist, where it is also recorded as blocked by PhishDestroy. The observed threat vector is classified as a brand impersonation targeting the brand x.com, though no additional payload or page content has been publicly disclosed.

At present, the primary uncertainties are the exact nature of any malicious payload that may have been hosted before the takedown and whether the infrastructure will be reused for future campaigns. Defenders should proactively block the domain and its associated IP address at perimeter and DNS filtering layers, add the domain to internal threat intelligence feeds, and monitor Cloudflare‑owned IP ranges for similar activity. Continuous observation of any new subdomains under the eu.com second‑level domain and periodic re‑scanning of the IP address are recommended to detect potential re‑activation of the infrastructure.
