Registrar contextNiceNIC
Stored registration data identifies NICENIC INTERNATIONAL GROUP CO., LIMITED (IANA 3765) as the registrar. PhishDestroy maintains separate NiceNIC abuse-report research; registrar association is contextual and is not an independent detection for this domain.
Analysis on huddle01.download indicates an active brand‑impersonation campaign targeting Discord users. The domain was registered on 21 February 2026 through NiceNIC International Group Co., Limited and resolves to the Cloudflare‑hosted address 66.33.60.67, which is announced as part of AS13335 (Cloudflare, Inc.) and located in the United States. The site is served behind Cloudflare, using HTTP/3 and presents a valid SSL certificate issued by Google Trust Services under the WE1 root, suggesting the TLS handshake is not being abused. However, the HTTP response code is 521, indicating that the origin server is refusing connections, a pattern often observed in temporary phishing infrastructure that relies on Cloudflare’s edge caching.
Reputation checks show a Gridinsoft trust score of 0 / 100 and three independent blocklists have already listed the domain. VirusTotal records show that 7 of 93 scanning engines have flagged the domain, and it appears in a single AlienVault OTX pulse, confirming that threat‑intel communities have observed malicious activity. The domain is also specifically blocked by PhishDestroy, MetaMask, and SEAL, reinforcing the classification as a brand‑impersonation site. The page title returned by the server is “Home – Huddle01’s Documentation”, which does not reference Discord and suggests the content may be a generic landing page used to host malicious payloads or credential‑harvesting forms, although the exact page content has not been publicly disclosed.
The primary uncertainty lies in the current state of the backend service, given the 521 status, and whether the site is actively serving phishing pages or merely staging infrastructure. Defenders should add 66.33.60.67 and huddle01.download to URL filtering and DNS block lists, monitor for any outbound connections to that IP, and enforce multi‑factor authentication for Discord accounts to mitigate credential compromise.

Registrar accreditation and DNS abuse obligations
For this gTLD, the registrar above operates under an ICANN accreditation agreement. The links below provide the official fee schedule and current DNS abuse compliance guidance.
Accreditation is a contract, not a safety certification.
RAA §3.18 establishes abuse-contact and handling requirements. This report can document stored outbound notices and later technical observations; it does not by itself establish receipt, investigation, remediation, or contractual non-compliance.
Saved certificate metadata. Certificate dates without a timezone are shown as stored. Transport encryption does not establish that the site is trustworthy.

Availability, content, DNS and registration are independent evidence layers. NXDOMAIN, an unreachable origin or missing content alone does not prove registrar action. A registrar or provider is credited only when a direct technical marker identifies that actor. Report causality is shown separately.
