This domain is flagged under active investigation for hosting a phishing site targeting Credicentro Coop customers. Analysis indicates a generic phishing threat, where attackers impersonate the financial institution to harvest login credentials, personal data, or financial details. The domain exhibits characteristics consistent with credential theft campaigns, including a deceptive page title matching the legitimate entity and infrastructure designed to evade initial detection. Infrastructure analysis reveals the following technical indicators: the domain was registered on June 25, 2026, through NICENIC INTERNATIONAL GROUP CO., LIMITED, a registrar frequently associated with malicious registrations. It currently resolves to IP address 104.21.24.13, a Cloudflare-hosted endpoint that may obscure the true origin of the phishing server. VirusTotal reports 0 out of 95 security vendors flagging the domain as malicious, suggesting it remains undetected by most automated systems. No blocklist entries or trust score downgrades were identified at the time of assessment, further complicating early identification. Mitigation steps for this threat type include immediate blacklisting of the domain and associated IP address in enterprise security controls. Network administrators should implement DNS filtering to block resolution of portal-web-seguro.com and monitor for connections to 104.21.24.13. Endpoint detection rules should be updated to flag processes attempting to access this domain, particularly those originating from browsers or email clients. Financial institutions and customers should be notified of the phishing campaign, with emphasis on verifying URLs before entering credentials. Given the domain's recent registration and lack of prior detections, continuous monitoring for related infrastructure (e.g., newly registered domains with similar naming patterns) is recommended to preempt further attacks.
