ksi303[.]org

Analysis of ksi303.org indicates an active brand‑impersonation infrastructure targeting the Etsy marketplace. The site returns HTTP 200 and is hosted behind Cloudflare (AS13335) with the IP address 104.21.22.235 located in the United States. DNS resolution uses felipe.ns.cloudflare.com and mariah.ns.cloudflare.com, and the domain was registered on 8 November 2025 through NameCheap, Inc. The TLS certificate is issued by Google Trust Services under the WE1 trust anchor, confirming that encrypted traffic is terminated at the Cloudflare edge. The page title, “KSI303 - Link Daftar Permainan Slot Resmi Mudah Akses Terupdate,” does not reference Etsy, but threat intelligence tags the site as impersonating the Etsy brand. Automated scanning on VirusTotal shows five of ninety‑three security vendors flagging the domain, and the Gridinsoft trust score is 0 out of 100, reinforcing malicious intent. Detected technologies include AMP, Google Tag Manager, Cloudflare, and HTTP/3, which are typical of legitimate sites, potentially aiding evasion. The domain appears on one public blocklist and has been blocked by the PhishDestroy filter. Given the high risk rating and active status, defenders should block the domain at network perimeter, monitor DNS queries for the associated IP and nameservers, and consider adding the host to internal threat‑intel feeds. Further investigation is needed to determine the exact phishing payload and credential‑capture mechanisms, as the page content has not been publicly analysed.
