help-upheld[.]webflow[.]io

help-upheld.webflow.io is flagged as a high‑risk generic phishing infrastructure as of 31 July 2026. The domain resolves to the IP address 104.18.36.248, which is owned by the Webflow hosting platform. Registration records show the domain was created through Webflow, Inc., indicating the use of a reputable SaaS website builder to obtain a legitimate‑looking TLS certificate and DNS configuration. Current DNS queries return no authoritative nameserver information (NS_NOT_FOUND), suggesting that the domain’s DNS records are either hidden behind Webflow’s proxy service or have been deliberately obscured.

The domain appears on three independent blocklists and has been reported by the phishing‑specific vendors PhishDestroy, MetaMask, and SEAL, all of which have added it to their deny lists. Despite these detections, the domain remains active and continues to resolve, implying that the malicious operator has not yet taken the site offline. Publicly available intelligence does not include a page title, SSL certificate details, HTTP response codes, or any associated malware kits, so the exact content and phishing vector remain unknown. Analysts should therefore treat any traffic to the domain as potentially malicious and enforce blocking at the network perimeter, proxy, and endpoint layers.

Monitoring of DNS resolution for 104.18.36.248 and any newly observed subdomains is recommended, as Webflow’s shared infrastructure may host additional related campaigns. Organizations using Webflow‑hosted assets should verify that their own domains are not inadvertently listed on blocklists and consider implementing strict content‑security policies to mitigate credential‑harvesting attempts. Continued observation of blocklist updates and vendor feeds will be necessary to capture any changes in the domain’s status.
