att[.]com-sbf[.]icu
“Welcome to nginx!”
証拠の概要
Analysis of att.com-sbf.icu indicates a confirmed phishing domain impersonating X.com, currently offline as of July 23, 2026. The domain was registered on February 21, 2026, through NAMEMART PTE. LTD. and resolves to 104.21.84.200, an IP address hosted on Cloudflare's network (AS13335) in the United States. Nameservers art.ns.cloudflare.com and grannbo.ns.cloudflare.com further confirm Cloudflare as the DNS provider.
No SSL certificate was detected, and the page title captured prior to takedown was 'Welcome to nginx!', suggesting the use of a default or misconfigured web server, which is atypical for legitimate brand-hosted infrastructure. The domain appears on one security blocklist and is blocked by PhishDestroy. Gridinsoft assigns a trust score of 0/100, reinforcing its malicious classification. While 15 of 93 security vendors on VirusTotal flagged this domain, the absence of recent scans or deeper forensic artifacts limits further assessment of its operational lifecycle or specific payload delivery mechanisms. The scam type is classified as brand impersonation, targeting X.com users, though the exact phishing kit or social engineering tactics employed remain unconfirmed due to the domain's offline status.
Defenders should treat this domain as high-risk infrastructure. Network-level blocking of 104.21.84.200 and monitoring for related subdomains or newly registered domains under the same registrar (NAMEMART PTE. LTD.) is recommended. Given Cloudflare's frequent use in phishing campaigns, additional scrutiny of domains leveraging its nameservers or IP ranges may uncover linked threats. No evidence suggests this domain is part of a broader campaign, but historical registration patterns or shared hosting indicators could emerge with further analysis.
