auths-io-coinsquare-cdn[.]webflow[.]io

The domain auths-io-coinsquare-cdn.webflow.io was observed hosting a page with the title “Coinsquare | Login”. The page was built on the Webflow platform and served through Cloudflare’s network, including support for HTTP/3. DNS resolution points to the IP address 104.18.36.248, which belongs to AS13335 Cloudflare, Inc. in the United States. The domain was registered through Webflow and currently reports no public nameserver information (NS_NOT_FOUND). HTTP requests to the site return a 403 status code, indicating that the server is actively refusing access, and the domain has been taken offline at the time of analysis. Threat intelligence categorizes the site as a credential‑phishing operation targeting users of the Coinsquare service.

The hosting provider and technology stack are consistent with many recent phishing deployments that leverage legitimate SaaS builders to obtain a trusted TLS certificate and reduce detection latency. The site appears on a single security blocklist and has been flagged by the PhishDestroy blocklist. Reputation scoring from Gridinsoft assigns a trust score of 0 out of 100, confirming a high confidence of malicious intent. VirusTotal analysis shows that 15 of 94 scanning engines flagged the domain, reinforcing the suspicion of phishing activity. While the page content has not been crawled, the combination of a brand‑specific login title, the use of a reputable content‑hosting service, and the low trust score collectively indicate a deliberate attempt to harvest Coinsquare credentials.

The lack of disclosed SSL certificate details, registrar information, and additional detection signatures limits a full attribution of the campaign infrastructure, but the observable indicators are sufficient for defensive action. Defenders should add the domain and its associated IP address (104.18.36.
