es-servicio-acceso[.]com

Analysis of es-servicio-acceso.com indicates an active high‑risk phishing campaign targeting the Cooperativa Ahorro y Crédito de Barranquitas. The domain was registered on February 21, 2026 through NiceNIC International Group Co., Limited and is hosted on Cloudflare’s network (AS13335) with the IP address 104.21.12.50 located in the United States. DNS resolution points to the Cloudflare nameservers cortney.ns.cloudflare.com and nikon.ns.cloudflare.com, confirming the use of Cloudflare’s reverse‑proxy services. The web server presents a WordPress stack backed by MySQL and PHP, fronted by Nginx and serving an HSTS‑enabled site.

A Google Trust Services / WE1 certificate secures the TLS connection, and HTTP requests return a 302 redirect, a pattern frequently observed in credential‑harvesting pages. The page title harvested from the site reads "Cooperativa Ahorro y Crédito de Barranquitas - ¡Nuestro centro eres Tú!", directly referencing the targeted financial institution. Security telemetry shows the domain appears on a single blocklist and is listed by PhishDestroy, while Gridinsoft assigns a trust score of 0 out of 100. VirusTotal scans report three of ninety‑three vendors flagging the domain, reinforcing the malicious classification.

Despite the relatively low number of vendor detections, the combination of a brand‑specific title, Cloudflare‑based infrastructure, low trust rating, and active blocklist entries warrants immediate defensive action. Organizations should add the domain and its resolving IP to web‑filter and DNS‑sinkhole policies, monitor outbound traffic for connections to 104.21.12.50, and educate users about unsolicited communications purporting to originate from the cooperativa. Continuous re‑evaluation is advised, as further indicators such as additional vendor flags or new blocklist listings may emerge.
