Analysis indicates that the domain ultrabaserpc.online was registered on February 21 2026 via Global Domain Group LLC and is hosted behind Cloudflare (AS13335) at IP 188.114.97.3 located in the United States. The site employs Cloudflare‑provided DNS (aleena.ns.cloudflare.com, clint.ns.cloudflare.com) and presents an SSL certificate identified as WE1. Gridinsoft assigns a trust score of 0/100, and the domain is listed on five external blocklists, including PhishDestroy, ScamSniffer, Polkadot, Enkrypt, and Codeesura. VirusTotal records show that 16 of 93 security vendors have flagged the domain, reinforcing its malicious reputation.
The intelligence classifies the operation as a “Fake Airdrop” campaign that impersonates the Ethereum brand, suggesting that victims may be lured with fraudulent token distribution promises. The site is currently offline, but the infrastructure components remain active and could be reused for future campaigns. Uncertainty remains regarding the exact payload delivered, any command‑and‑control endpoints, and whether the SSL certificate is self‑signed or issued by a trusted CA, because the certificate details are limited to the label WE1.
Defenders should block the domain and its associated IP at perimeter firewalls, add the observed nameservers and IP to DNS sinkhole lists, and monitor for any resurgence of the same Cloudflare‑hosted infrastructure. Continuous re‑scanning with VirusTotal and inclusion of the domain in internal threat intel feeds are recommended to capture any re‑activation. Organizations handling Ethereum assets should educate users about unsolicited airdrop offers and enforce verification of official communication channels.

認定と RAA の背景
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.
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.

About this reportSources, observation dates and corrections
This report combines saved page captures, registration and network records, scanner results and PhishDestroy reporting history. Each source keeps its own observation date. Open a source report to inspect the original result.
The AI-assisted analysis was written on . It describes the evidence available at that time; later source checks can change.
A capture documents what was shown. A scanner result records that provider’s assessment at the time of its check. Neither a valid certificate nor a zero-detection result is a guarantee of safety.
