This domain is flagged as a confirmed credential harvesting phishing site designed to deceive users into submitting sensitive login credentials. Analysis indicates the infrastructure is specifically crafted to mimic legitimate services, leveraging social engineering tactics to exploit trust. The threat type is classified as elevated due to its active deployment of deceptive frontend components and backend data exfiltration mechanisms. Infrastructure analysis reveals the following technical indicators: the domain resolves to IP address 198.251.84.200 and was registered on March 21, 2026, through HOSTINGER operations, UAB. Security vendors on VirusTotal flagged the domain with 12 detections out of 95 engines, while it appears on one security blocklist. The site employs Let's Encrypt SSL certificates, Tailwind CSS for styling, LiteSpeed web server, Alpine.js for dynamic interactions, Smartsupp for live chat simulation, jsDelivr for content delivery, and HTTP/3 for optimized performance. The page title, 'Home - rscityb,' suggests an attempt to present a generic yet plausible facade. Mitigation steps for this specific threat type include immediate blocking of the domain and its associated IP address (198.251.84.200) at the network perimeter. Organizations should deploy indicators of compromise (IOCs) such as the domain, IP, and SSL certificate fingerprint into security monitoring systems to detect related activity. End-users who may have interacted with the site should be instructed to reset credentials for any accounts accessed during the exposure window, particularly if reused across platforms. Security teams are advised to conduct a retrospective analysis of logs for connections to the domain or IP, focusing on authentication events and outbound data transfers. Proactive measures include implementing multi-factor authentication (MFA) and domain-based message authentication (DMARC) policies to reduce the risk of similar phishing attempts.

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.

11 recorded events. These records describe collected evidence, outgoing notifications and publication; they do not confirm a complete investigation or a takedown.
A stored Cloudflare Radar report is available. The report link alone is not a malicious verdict and does not prove that every network field was captured.
We scan suspicious URLs, inspect public results and send evidence through the appropriate abuse-reporting channels. The dated events above show what is recorded for this domain. The directory below explains the wider workflow.
