casi-gir[.]app

Analysis of the domain casi-gir.app shows a newly registered (26 Mar 2026) site that is actively serving content protected by Cloudflare. The domain resolves to IP 188.114.97.3, which belongs to Cloudflare, Inc. and is geolocated in Canada. DNS is hosted on Cloudflare nameservers ariadne.ns.cloudflare.com and brian.ns.cloudflare.com, and the TLS certificate is issued by Google Trust Services under the WE1 authority, indicating a legitimate‑looking HTTPS endpoint. HTTP requests return a 403 status and the page title is limited to "Just a moment...", suggesting the site is using Cloudflare’s challenge page rather than exposing its payload directly. Threat intelligence flags include detection by 2 of 94 VirusTotal scanners, a Gridinsoft trust score of 0 / 100, inclusion on a single security blocklist, and a listing in an AlienVault OTX pulse. The domain is also blocked by PhishDestroy, confirming active abuse. While the exact phishing content has not been captured, the combination of recent registration, Cloudflare protection, low trust scores, and multiple independent detections points to a high‑risk phishing operation. Defenders should add casi-gir.app to outbound web filtering rules, enforce DNS blocklists that include the domain, monitor for any related C2 activity to the resolved IP, and alert users about potential credential harvesting attempts associated with this URL. Continuous re‑scanning of the domain is advised to capture any evolving payloads.
