sso-blockfi--login[.]webflow[.]io

This domain, sso-blockfi--login.webflow.io, is actively flagged as a high-risk credential phishing site targeting BlockFi single sign-on (SSO) credentials. Analysis indicates the domain was registered through Webflow, Inc., and currently resolves to IP address 104.18.36.248, a Cloudflare-hosted endpoint. As of July 22, 2026, 13 of 95 security vendors on VirusTotal detect this domain as malicious, and it appears on at least one security blocklist, specifically PhishDestroy. The domain lacks configured nameservers, which may indicate an incomplete or hastily deployed infrastructure, though this does not reduce its immediate threat level.

Defenders should note that the domain remains active and continues to resolve, suggesting ongoing phishing operations. The use of Webflow as a hosting platform is consistent with attacker tactics to leverage legitimate services for rapid deployment and evasion of traditional blocklisting. While the exact content of the phishing page has not been analyzed, the domain name explicitly references BlockFi SSO, indicating an intent to harvest credentials under the guise of a legitimate authentication portal. Recommended actions include blocking the domain at DNS and proxy levels, monitoring for connections to 104.18.36.248, and reviewing logs for any internal access attempts.

Given the high detection rate and active status, this domain should be treated as a confirmed threat vector. No SSL or HTTP status anomalies are reported, but the absence of nameservers may warrant further investigation into the domain's registration lifecycle. Additional context, such as phishing kit signatures or victim reports, is not currently available.
