claude-ai[.]cyou

The domain claude-ai.cyou was registered on July 22, 2026 through GLOBAL ASSET DOMAINS INC and is served by Cloudflare nameservers arushi.ns.cloudflare.com and kevin.ns.cloudflare.com. DNS resolution points to the IP address 104.21.46.254, a Cloudflare edge node that provides generic content delivery and does not disclose the underlying hosting infrastructure. The domain appears on a single security blocklist, identified by PhishDestroy, indicating that at least one external threat‑intelligence source has flagged it for malicious activity.

VirusTotal analysis shows that 2 of 91 security vendors have marked the domain as suspicious, confirming limited but non‑trivial detection by automated scanners. No additional public blocklists, Safe Browsing entries, or open threat‑exchange (OTX) references are currently listed for this domain. The short lifespan—only four days from registration to the report date—combined with the use of a reputable CDN and a minimal detection footprint suggests a deliberate attempt to leverage the anonymity and performance benefits of Cloudflare while evading rapid reputation buildup.

Defenders should treat the domain as high‑risk, given its classification as a generic phishing site and its presence on PhishDestroy. Recommended actions include adding the domain to outbound and inbound firewall deny lists, monitoring DNS queries for the associated IP address, and employing URL filtering solutions that reference the blocklist entry. Continuous re‑evaluation is advised, as additional detections may emerge from broader scanning platforms or victim reports, potentially increasing the detection count and expanding blocklist coverage.
