Analysis of sia.inicioseguro.com indicates an active phishing domain impersonating Indra Group, as evidenced by the page title 'Indra Group Clientes múltiples' observed on July 19, 2026. The domain resolves to IP 76.223.11.49, hosted on AWS Global Accelerator infrastructure in the US, and is registered through GoDaddy.com, LLC with DNS managed by dnsimple.com nameservers. The site presents a valid HTTP 200 status, suggesting operational functionality, and uses a Let's Encrypt SSL certificate (YR1), which does not inherently indicate legitimacy due to its common use in malicious campaigns. As of the report date, the domain appears on one security blocklist (PhishDestroy) and is flagged by 12 of 91 security vendors on VirusTotal, though the specific detection rules and malicious behaviors identified by these vendors are not detailed in available intelligence. The impersonation of Indra Group, a known technology and defense contractor, suggests targeting of corporate or government clients seeking access to client portals or secure services. Defenders should note the domain's continued activity despite blocklist presence, indicating potential evasion of automated defenses. Recommended actions include blocking the domain and IP at network perimeter controls, monitoring for credential submission attempts linked to this infrastructure, and alerting personnel to verify Indra Group communications through official channels. Further investigation into associated email campaigns or distribution vectors is advised, as the domain's hosting on AWS Global Accelerator may facilitate rapid scaling or redirection to additional malicious endpoints.
