LIMITED and currently resolves to IP address 104.21.88.59 located in CA under Cloudflare infrastructure. The domain uses nameservers craig.ns.cloudflare.com and elaine.ns.cloudflare.com along with detected technologies including Cloudflare Browser Insights and HTTP/3. An SSL certificate issued by Let's Encrypt E7 is present. The site returns HTTP status 403 and displays the page title Site is created successfully. Gridinsoft assigns a trust score of 0/100 while VirusTotal reports 3 detections out of 95 vendors and one blocklist entry exists. AlienVault OTX lists the domain in a single threat pulse and PhishDestroy has applied a block. The threat classification is generic_phishing with high risk and active status confirmed on July 12 2026. What remains uncertain is the precise payload or target brand because the 403 response prevents direct content inspection and no additional campaign artifacts are recorded. Infrastructure analysis reveals standard Cloudflare proxying that obscures origin details and the short registration-to-detection window aligns with patterns seen in disposable phishing infrastructure. Defenders should add casibom-duble.com to internal blocklists and DNS sinkholes immediately. Network monitoring teams can correlate traffic to 104.21.88.59 and the listed Cloudflare nameservers for related indicators. Incident responders are advised to review logs for any prior resolutions or redirects from this domain and to share observed artifacts with threat intelligence platforms to refine blocklist coverage. Continued observation of the IP range and certificate transparency logs is recommended to detect potential successor domains created under the same registrar pattern.
