证据摘要

重要

The domain linea-bulid.app was registered on March 26, 2026 through NICENIC INTERNATIONAL GROUP CO., LIMITED and is currently resolved to the Cloudflare edge address 172.67.152.4, which geo‑locates to Canada. The site presents a HTTP 403 response and its page title is "Just a moment...". The TLS certificate is issued by Google Trust Services under the WE1 root, indicating use of a legitimate certificate authority but not confirming the legitimacy of the content. The domain is classified as a brand‑impersonation campaign targeting the Linea brand, and its risk level has been assessed as high.

Infrastructure analysis shows the domain is delegated to Cloudflare name servers (harmony.ns.cloudflare.com and randy.ns.cloudflare.com), a common choice for fast‑changing malicious infrastructure. Reputation services flag the domain heavily: Gridinsoft assigns a trust score of 0 out of 100, VirusTotal reports 8 out of 95 security vendors flagging the host, and AlienVault OTX lists the domain in one threat‑intelligence pulse. It appears on a single public blocklist and has been actively blocked by the PhishDestroy service. These indicators collectively suggest a coordinated impersonation effort rather than an isolated misconfiguration.

Defenders should add linea-bulid.app to network and endpoint blocklists, enforce DNS sink‑holing for the domain, and monitor for any outbound connections to its IP address. Continuous observation of Cloudflare‑associated IP ranges for similar activity is advised, as the attacker may shift hosting within the same provider. Organizations that rely on the Linea brand should educate users about the presence of this malicious site and reinforce verification of legitimate URLs, especially given the domain’s recent creation and active status.

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.
