casigo[.]org

Analysis conducted on July 25, 2026 identifies the domain casigo.org as an active component of a cryptocurrency‑focused phishing campaign. The site was registered on September 25, 2025 through NameSilo, LLC and resolves to the Cloudflare address 104.21.16.87, belonging to AS13335 Cloudflare, Inc. in the United States. The domain is served by the Cloudflare nameservers devin.ns.cloudflare.com and savanna.ns.cloudflare.com and currently returns no SSL certificate, indicating an unsecured HTTP service. The page title retrieved from the live host reads “Casigo: Most Popular Online Crypto Casino Based on Blockchain,” which aligns with the “Crypto Scam” classification and the “Gambler Scam” phishing kit observed in related threat intel. Reputation services uniformly assign extremely low trust scores: Gridinsoft rates the domain 1 / 100, and Scamadviser also reports a 1 / 100 rating.

The domain appears on a single security blocklist and has been explicitly blocked by the PhishDestroy feed. VirusTotal scans show that 11 of 93 antivirus and URL‑reputation engines flag the domain as malicious, reinforcing the suspicion of phishing activity despite the modest detection count. No valid SSL/TLS certificate is present, further reducing confidence in the site’s legitimacy. The available evidence confirms that casigo.org is being used to lure victims into a crypto‑casino scam, likely attempting to harvest cryptocurrency wallet credentials or payments.

However, the offline status reported at the time of analysis prevents direct observation of the payload or credential‑capture mechanisms, leaving the exact phishing workflow uncertain. Defenders should continue to block the domain at network perimeter and DNS layers, monitor for any outbound connections to the IP 104.21.16.87, and update intrusion‑detection signatures with the observed page title and known kit identifiers.
