This domain was observed on July 19, 2026 as an active credential phishing vector. The hostname signin-collab.land resolves to the Cloudflare‑hosted address 104.21.62.45, which is located in Canada and is served by Cloudflare, Inc. The domain is registered through NICENIC INTERNATIONAL GROUP CO., LIMITED and uses the Cloudflare nameservers sofia.ns.cloudflare.com and nile.ns.cloudflare.com. HTTP requests return a 200 status code and the TLS certificate is issued by Google Trust Services under the WE1 profile, indicating a valid certificate chain. The domain appears on a single security blocklist and is listed as blocked by PhishDestroy. VirusTotal reports four detections out of ninety‑one scanners, confirming that multiple security products have flagged the site. The available intelligence classifies the campaign as credential phishing, but the specific payload, target brand, and page content have not been publicly disclosed. Defenders should deny outbound connections to 104.21.62.45, add signin-collab.land to DNS and URL filtering rules, and continue monitoring for any related C2 domains or newly observed IPs. Given the active status and detection by multiple vendors, the domain should be treated as high‑risk until takedown confirmation.

认证和 RAA 背景

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.

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.
