huddle01[.]download

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.
