证据摘要

HIGH

The domain kastc.xyz presented a page titled "Welcome to nginx!" while impersonating the brand x.com as part of an impersonation scam. This site posed a threat by attempting to deceive users into believing it was associated with x.com, potentially to harvest credentials or spread malware through a fraudulent interface.

Technical analysis shows the site was flagged by 6 out of 95 VirusTotal vendors, with detections from ChainPatrol, alphaMountain.ai, CyRadar, Forcepoint ThreatSeeker, and Seclookup. It was listed on 1 blocklist. The domain was registered through Spaceship, Inc. and created on 2025-10-01. It resolved to IP address 104.21.79.47 in the United States, hosted by AS13335 Cloudflare, Inc. The site used an SSL certificate from Google Trust Services / WE1, with nameservers donovan.ns.cloudflare.com and itzel.ns.cloudflare.com.

The site is currently DOWN/OFFLINE. GridinSoft trust rating is 0/100, and the DOM risk score is 10, indicating a high-risk profile. Given the impersonation of x.com and the low trust metrics, this domain should be treated as malicious and blocked.

认证和 RAA 背景

Registrar accreditation and DNS abuse obligations

For this gTLD, the registrar above operates under an ICANN accreditation agreement. The links below provide the official fee schedule and current DNS abuse compliance guidance.

Accreditation is a contract, not a safety certification.

RAA §3.18 establishes abuse-contact and handling requirements. This report can document stored outbound notices and later technical observations; it does not by itself establish receipt, investigation, remediation, or contractual non-compliance.
