besttenbook[.]org

The domain besttenbook.org was registered on November 1, 2025 through Cloudflare, Inc. and resolves to the Cloudflare edge IP 104.21.95.149, which is associated with ASN 13335 in the United States. The site is protected by a Google Trust Services certificate issued under the WE1 intermediate, indicating a valid TLS handshake. DNS resolution is served by donovan.ns.cloudflare.com and ines.ns.cloudflare.com, confirming the use of Cloudflare’s authoritative name servers. Network analysis shows the service is delivering content over HTTP/3, a feature commonly observed on modern Cloudflare‑hosted sites.

The only publicly visible page title is “Best Ten Book – Top 10 Book Reviews & Reading Recommendations,” suggesting a content‑focused front end, but no further content has been captured. The domain is currently listed as offline in the latest scan, and it appears on one security blocklist. VirusTotal reports that two of ninety‑five scanning engines have flagged the domain, providing additional corroboration of malicious intent. PhishDestroy also lists the domain as blocked, reinforcing its classification as a phishing resource.

Despite the limited surface‑level information, the convergence of a recent registration date, Cloudflare‑based hosting, a valid SSL certificate, and multiple independent detections strongly indicates that besttenbook.org is being leveraged for generic phishing campaigns. The exact payload, target audience, or credential‑harvesting mechanisms have not been observed, leaving those details uncertain. Defenders should continue to block the domain at perimeter firewalls and DNS filtering solutions, monitor for any new resolution or content changes, and consider adding the IP address 104.21.95.149 to any host‑based deny lists.
