jonnysilver[.]win

Analysis of jonnysilver.win, created on 17 September 2025 and currently taken offline, indicates a generic phishing operation using a Gambler Scam kit that impersonates a crypto casino. The domain resolves to IP 188.114.96.3, which belongs to AS13335 Cloudflare, Inc., placing the hosting infrastructure within the United States. DNS resolution is handled by Cloudflare nameservers jamie.ns.cloudflare.com and wilson.ns.cloudflare.com, a common pattern for fast‑flux or abuse‑resilient campaigns. The site presented an HTTP 403 response at the time of observation, suggesting that the content is being actively blocked or that the operator has removed the page after detection. SSL is provided by Google Trust Services under the WE1 certificate chain, indicating a valid TLS certificate that may lend credibility to victims.

The page title “Jonnysilver: Most Popular Online Crypto Casino Based on Blockchain” aligns with the brand‑impersonation scam type, yet no further page content has been captured, leaving the exact lure and credential‑collection mechanisms unverified. Security telemetry shows that 15 of 91 VirusTotal scanners flagged the domain, and it appears on a single external blocklist maintained by PhishDestroy, confirming that at least one reputable anti‑phishing feed has recognized the threat. Gridinsoft assigned a trust score of 0/100, reinforcing the malicious classification. Registration was performed through NameSilo, LLC, a registrar frequently used by short‑lived malicious sites.

Defenders should immediately block the hostname and its associated IP address at perimeter and DNS layers, and add the domain to internal phishing and URL filtering policies. Given the Cloudflare hosting, consider employing rate‑limiting or CAPTCHAs for outbound connections to the IP range if legitimate traffic is expected.
